Rutaceae week: Citrus sp. from Hooghly:
I recorded these pictures in three villages in Hooghly. I do not know the correct ID of this lime. I was trying to get hold on C. aurantifolia and C. medica by going through previously uploaded group messages. But it is still not clear to me. Though the attached pictures were taken from four individual shrubs, from time to time since 2009, i hope the plant species is same in each photograph.

Species : Citrus aurantifolia ???
Habit & Habitat : shrub, garden, backyard
Date : please see the text
Place : please see the text
PHOTO SET 1 : pictures taken on 09-May-2012, 10.30 A.M. at Garalgacha (Hooghly) :-
PHOTO SET 2 : pictures taken on 10-May-2012, 02.10 P.M. at Krishnapur (Hooghly) :-
PHOTO SET 3 : pictures taken on 06-May-2012, 09.50 A.M. at Nalikul (Hooghly) :-
This plant is a safe resting shade for birds (my own backyard in 2009 & 2010) :-
This species is also LF plant of various butterflies (my own backyard in 2009 & 2010) :-
This is my last post in the ongoing Rutaceae week. I feel sad that i do not know any more member of this family.

I cannot comment on the exact id of the posted plant, but that doesn’t stop me liking your beautiful post, shows the time taken, patience and a keen observation. Thanks for all yours efforts to share this information….


These days the birds are going wary. I think rapid destruction of their habitat is greatly reducing their numbers. Their food and nesting habit are also changing. It was easier to photograph a bird in 2009, even with a 5x zoom!


I think this is Citrus aurantifolia (Christm.) Swingle.
My guess is based on the following websites/document –
Some more related links –

Pl. also consider Citrus longilimon, as per images and details herein.


I am not sure, Sir, how about Citrus × limon (L.) Osbeck of KEW or FoC, and synonymous with Citrus limon (L.) Osbeck of BSI?


Yes, the taxonomy of Citrus is quite complex with different databases saying different things.
Citrus longilimon is an unplaced name as per POWO (and not accepted by Govaerts, R., Nic Lughadha, E., Black, N., Turner, R. & Paton, A. (2021)) and not found in CoL and TPL.
So we may very well keep it at Citrus limon, for the time being.

I photographed it this morning. A 10 ft shrub, didn’t find flower, fruits are about 2 inches long.
I think this is same as in my previous post.

efi page on Citrus medica  


To me this is a cultivar of Citrus aurantiifolia


Is Citrus aurantiifolia same as Citrus x aurantiifolia?
Is Citrus aurantiifolia same as C. aurantifolia?
Is Citrus aurantiifolia synonymous with C. medica var. acida?

If I am not mistaken, yes it is.


Thank you very much again, …
The problem is Flora of Pakistan treats C. medica var. acida and C. aurantifolia two different taxa.

ran out of film
but whatever is showing
these donot look anything like the gondhoraj lebu
I remember running my fingers on the yellow skin and scent inhaling… was nice but not gondhoraj scent
the  gardener working “really keeping an eye on ” visitors said the lebus had seeds and was quite sour to taste…  he was not impressed with any nostalgia imposing scent…
please read these modern papers,  right now I have to run but I promise I will also read it again.. i had discovered this edu site a few years ago, very thorough professors …
http://websites.lib.ucr.edu/calssification
their 3 is also quite informative


Thank you Didi, I took a quick glance this afternoon, very informative, but not helpful to species level ID, I think.


I agree with …, this is likely to be C. aurantiifolia or hybrid.


that was the idea, …
its one of the myriad hybrids
did it not strike you that out of the lemon seeds or saplings carried westward by the arab caravans and sold to italians et at ( venice was a trading post for them) … so many cultivars and then hybrids developed in a span of only a couple of centuries…??
AND EVERYBODY AT EFLORAINDIA THAT GET THIS EMAIL:
think of the big picture and why was lemon a center of so..oo..o much activity, in the western world in several continents including australia, starting in the late 15th century to 17th century especially … and in california and florida in 19th and 20th century…these chapters show us that activity…???
but why???
I know it, do you?
I want to hear all the stories and ideas

Except for commercial exploitation I fail to think of any other cause. The Citrus is/was mostly Asian origin, rather SE Asia.


the chapter 3 i said was more informative
that’s where the keys are for the whole clan and kaboodle
citrus  is halfway down the page/chapter

you’ll have more than what you want
chapter title is : The Botany of Citrus and Its Wild Relatives
BY WALTER T. SWINGLE
Revised by Phillip C. Reece CHAPTER 3
its from UC Riverside
they do a good job

Thank you very much Didi for the link and details. This shrub cannot be true Citrus aurantifolia for it has leaves as large as 10 to 15 cm., never small like our PATILEBU, petioles are not winged, even faintly. At best it can be a hybrid.


Pl. also consider Citrus longilimon, as per images and details herein.


I guess you are right … !
https://efloraofindia.com/2011/02/15/citrus-longilimon/


Very confusing, Sir, I would rather prefer Citrus sp. only.


Same as at Rutaceae week: Citrus sp. from Hooghly


Yes, Sir, I fully agree.

Seen at the Flower Show in Lalbagh yesterday. (21.1.20)

It looks like those fruits of C. aurantiifolia at efI, but here the skin is too smooth. So, I am not sure if it can be same species, specially since it is displayed in a flower show. 


Thanks for the possible id.
Unfortunately, there were no names on display.

Fruits & Vegetables Week: Citrus limon, the lemon:
Citrus limon, the lemon, the commonest source of lemon juice, the fruit characteristically pointed at the tip.


– This in Marathi is called Idlimbu???? Just recently when  had been to Sibsagar Assam, I saw that almost all houses had a tree of ths plant along with Aamla. In their daily meals they take a large piece of this lemon either cut round or elongated. They eat it just like that or with salt. I know that it is a good source of Vit C, but eating such a big piece of lemon raw by everybody, without exception was new to me. Why so much vit C is consumed? How come every house has there qwn trees of lemon and Aamala? Can somebody from Asssam on the group explai? They also presented around a dozen of these lemons to each of us. I could make two bottles of pickeles of it.


– In California also I found one big slice of lemon being served with most dishes and often fixed on the top a glass of lemonade or juice, or a bowl of salad. Matter of in plenty and use.


– Even though it is acidic in nature, it is good for acidity and the body absorbs the vitamins better from the food, if it is mixed with the lemon juice.

Fruit for Id pl.
Which is this Citrus species ? Looks much bigger than the usual ones.
Location –  Ghatghar, Uttarakhand.
Date – 21.11.2016

Citrus species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available on net)


To me, this is still Citrus aurantifolia, because in our country there are some cultivars of it which can be globose or oblong, small or big, green or yellowish at maturity.


Looks like Galgal lemon, Citrus x limon (L.) Burm.f. (= C.pseudolimon Tanaka). Could you post a close up of the leaf and the CS of fruit?


Posting two more photos for reference. Attachments (2)


Yes, to me it appears to be a large fruited hill lemon or galgal lemon!

Beautiful, yes. Please, I have a question; my curiosity. I looked at both The Catalogue of Life and The Plant List, no result. I did find it listed here: Citrus limon (L.) Burm.f. syn. C.medica L. var. limon.
Any idea why it would not be listed? Thank you.


Earlier it was listed in GRIN. But this link is not opening now.
I tried but could not help more than this.

Citrus limonia – efloraofindia | Google Groups:
Citrus limonia (Gandharaj Lemon) from my terrace garden giving lots of fruits these days, photos taken today morning, I took out two of these limes with one I made nimbu pani whcih I am enjoying now to beat the summer heat other will be included in my lunch Ha ha ha . Please see the thorn at the leaf axil and also presence of oil glands on leaf and fruits .. they smell awesome!!


Fruits have some brown patches. Are the infected with Citrus Cancker ?


Taxonomy of Citrus is perhaps most complex. Wish we have good collection on our website.


I Use phosphate, but mostly rely on compost fertilizers. I also add a lot of manure (cow dung) to it, Seems to be fruiting well for last 3 yrs . Yes my pot is big one .
 Dear Satish ji,
My plant is not at all infected with cranker it developed because the fruits were developing in the shade of the leaf  in hindi we tell ” Patte ki daag” ..I grow them on terrace garden hence some times they end up developing near the wall and get hold of  such spots. Plants infected with citrus canker have characteristic lesions on leaves, stems, and fruit with raised, brown, water-soaked margins, usually with a yellow halo or ring effect around the lesion. Older lesions have a corky appearance, still in many cases retaining the halo effect. The bacterium propagates in lesions in leaves, stems, and fruit. The lesions ooze bacterial cells that, when dispersed by windblown rain, can spread to other plants in the area. Infection may spread further by hurricanes. The disease can also be spread by from contaminated equipment, and by transport of infected or apparently healthy plants. Due to latency of the disease, a plant may appear to be healthy, but actually be infected.
Citrus canker bacteria [Xanthomonas axonopodis]can enter through a plant’s stomata or through wounds on leaves or other green parts. In most cases, younger leaves are considered to be the most susceptible. Also, damage caused by Citrus Leaf Miner larvae (Phyllocnistis citrella) can be sites for infection to occur. Within a controlled laboratory setting, symptoms can appear in 14 days following inoculation into a susceptible host. In the field environment, the time for symptoms to appear and be clearly discernible from other foliar diseases varies; it may be on the order of several months after infection. Lower temperature increases the latency of the disease. Citrus canker bacteria can stay viable in old lesions and other plant surfaces for several months.

2015april_sk33/33 : GANDHORAJ LEBU ? : 6 posts by 3 authors. Attachments (4)
A seller was selling these as GANDHORAJ LEBU in our market. I bought 3 at Rs. 10/-. The fruits are seedless, acidic (not much), smells like usual PATI-LEBU, though a bit stronger. I do not know if this can be gandhoraj lebu. But surely it’s a hybrid, being seedless.

product of : a lemon (shape) and lime (not too acidic and thinnish rind) … and added bonus to them … seed less…
not gondoraj …if not really strongly scented
but on krishi vigyan show they had talked of many varieties of lebu a farmer could plant in west bengal
i did not take notes but it can be traced
the speaker was from kalyani univ
i wish they would have websites and all the information written up and handy
like the extension office websites of many aggie colleges and univ in USA
in one many many years ago i had even found varieties of patol one could grow profitably in florida soils and weather for the local indian populations and ..listen to this for export to india… bojo… but for here …i am hoping.. lets hope

Yes Didi, I think now there is no use of finding species level ID of these lebu(s)!


Citrus longilimon, Assam lemon, with elongated fruit, discussed so many times on our group
efi thread 1
efi thread 2


ah, so I was on the right track, in a nonbotanist way
I thought it was a lime masquerading as a lemon or vice versa
but the assam lemons i think have seeds if i am not mistaken


…, thank you. I understand that it comes from lemon (limon) group.


BSI key & description of Citrus – http://efloraindia.nic.in/efloraindia/taxonList.action?id=3636&type=3, There are a few pics and illustrations in species pages too.
Thanks to Japan for providing open access to the document – “A revision of Assam Citrus“.
Where does BSI fit Citrus longelimon Tanaka n. sp.?


I think close to images and details at Citrus × limon (L.) Osbeck


Gandhoraj or Assam lemon is important cv of Lemon. In fruit, Seeds are less and juice gives aroma.

Citrus limon L., also called Nemu Tenga in Assamese.


Although most official sites of NE mention C. limon as botanical name, seeing the shape of fruit, this is what I dug out from the Site Sorting Plant names:

Citrus longilimon Tanaka

ENGLISH : Assam lemon, Long-fruited lemon, Oblong lemon.

FRENCH : Citron des Indes à fruit long.
JAPANESE :   アッサムレモン  Assamu remon.
VIETNAMESE :  Chanh Assam, Chanh quả dài.


Taking it as Citrus × limon (L.) Osbeck, as per details herein.


Assam lemon cv. is famous in the world for special qualities.

Rutaceae week: Assam lemon ? at Mizoram:
Came across this Citron Sp. at Mizoram.

Earlier, in one of the discussion this was identified as Citrus longilimon Tanaka.

If these are the flowers of C. longilimon, these are the non-Indian names for it:
Citrus longilimon Tanaka
CHINESE : 阿萨姆柠檬 A sa mu ning meng.

ENGLISH : Assam lemon, Long-fruited lemon, Oblong lemon.

FRENCH : Citron des Indes à fruit long.

JAPANESE :  アッサムレモン Assamu remon.
VIETNAMESE : Chanh Assam,
Chanh quả dài.
What are the names from India ??

Yes … and … This plant has been well discussed on our group after … uploaded it in 2010:

Here is my note from that:
Assam lemon, characterised by its long fruits (distinctinctly longer than broad) have been named as C. limon at many websites, and as C. medica in many websites. It should not look strange firstly because taxonomy of Citrus is very confusing, secondly many authors consider C. limon as var. or subsp. of C. medica, and as such those not going below species level would simply call it C. medica. Plus C. longilimon (character is in the name itself) is comparatively recently established species, not known to me. NMPMD database is generally well researched, and it is from here as well photographs of Assam lemon at various websites that C. longilimon appears to be the most logical name. Plus GRIN also recognises it as distinct species.
C. limon is generally differentiated from C. medica by much thinner and smoother rind. Let us try to find out other differentiating features (in addition to longer fruit) of C. longilimon to arrive at final conclusion.
Before that … had also uploaded the plant

Taking it as Citrus × limon (L.) Osbeck, as per details herein.
