This is Osbeckia stellata.

In Osbeckia– stamens are equal in length and shape, but in Melastoma– stamens are unequal in length and shape. In this picture stamens are equal in length. So i think this is Osbeckia only.


Yes Osbeckia stellata

Osbeckia stellata Wallich ex D.Don (Melastomaceae) is a frequent shrub in mid hills of Uttarakhand. It produces beautiful flowers during June-September.
With this tricoloured flower I salute TRICOLOUR OF INDIA.

Thanks … for sharing.. we searched for this plant in present tour of Chakrata region (as we had found this during our tour in September 2011), but no trace was found, probably due to the fact that all roads were not open for traffic and we could not visit the area of its distribution..

as we were returning back through other route we had completely ended the search for this, even this was out of mind… and we were happy to find the beautiful flowers greeting us.. sharing one of my latest pics..


Prominently SIGMOID anther lobes are clearly visible. This is what I wanted to discuss in the group on my plant and the one given on Flowers of India.

Likely to be Sarcopyramis napalensis or else Osbeckia stellata.


Thanks… To me it is not S.nepalensis. Probably Osbeckia stellata.


Okay, agreed, Osbeckia stellata. However, the spelling for the other species will not be nepalensis but napalensis, as per the protologue.  Please mention the stature of the plant in your posts.

All major Floras of Himachal Pradesh has listed presence of O. stellata in the state. Flora of Himachal Pradesh by Chaudhary and Wadhwa has mentioned presence of O. chinensis from Kangra. 


Not familiar with any Osbeckia, yet it raises my interest. The problem is –

Can’t say if the above two are synonymous or not. I have read Anil Ji’s attached document.
Descriptions of both in Flora of British India leave one confused. However, Fl. Br. Ind. referred to biodiversitylibrary where the flower is purple (or pure white).

I would rather go with O. stellata Buch.-Ham. ex Ker Gawl, as in FoC; until we get the latest revision of the genus.


i mean the illustration at biodiversitylibrary is of O. crinita of Fl. Br. Ind.

Sir W. J. Hooker treated the above as synonymous with O. stellata.(as had been described in FBI).


I will also go with Osbeckia stellata.

Yes, O. stellata. Excellent images! Also in Sikkim and Bhutan.


Please suggest if these pics belong to Osbeckia stelllata, they were recorded from Assam-Arunachal border this year..

I am no expert but I had seen this plant at many places in Sikkim at low altitudes. The species is unmistakable by  the hirsute branches, the terminal umbellate panicles and the 4-merous flowers with violet petals.

Enclosing suggestion received from member for your opinion please !

Dear …,
My compliments to you on treating us with Nepal Flora.
This does seem to be O. stellata. (keys below).
Up to what altitude do you see this plant in Nepal?
It is said to occur between 700-1600m, however, I have sighted this plant at about 3700m in October 2009 in Sikkim on the Goecha la route between Pheydang and Kokchurung. 
Will be happy to learn of your view.
If Hypanthium (calyx Cup) 4–7 mm long……..1. Osbeckia chinensis                       

                                                                  2. O. nutans
If Hypanthium 10–23 mm long:
Lamina 17–25 mm long…………………….. …..3. O. capitata

Lamina 40–130 mm long: Flowers 5-merous…………………. ……………4. O. nepalensis
Flowers 4-merous………………….…………….5. O. stellata

2nd mail
My apologies for this second communication.
I feel that the plant in your post (on eFI) of August 08, 2016 is not O. stellata.
Please refer to the keys sent to you in earlier mail.
It looks like O. chinensis to me as hypanthium seems smaller.
Attaching what I think is O. stellata from my collection.

Look forward to your views.


Your observations about what you thought was Osbeckia stellata on the Goecha La route at some 3700m caught my eye.
This struck me as much higher an elevation than previously recorded. According to ‘Enumeration of the Flowering Plants of Nepal’ Vol 2 (1979) the highest O.stellata was known from was 2600m.  For a species to be recorded 1100m higher than ever before, would be most surprising.  All that can be said is that according to your memory, based upon a quick glance, you came across what you thought was probably O.stellata.  Do you have any photos or specimens to support this surprising suggestion?
‘Flowers of the Himalaya’ says 1200-2400m, Uttarakhand to Arunachal Pradesh and what was Burma for Oxytropis stellata.
R. Clement in ‘Flora of Bhutan’ Vol 2 Part 1 (1991) which also covered Sikkim (which as you known borders E.Nepal and now being Indian territory is of particular interest to eFI members) says O.stellata is extremely variable and a number of authors have recognised the differences at specific level. Hansen (1977) ‘Asiatic species of Osbeckia (Ginkgoana 4: 1-150) considered the taxa poorly defined, recognising taxa within O.stellata. Clement adopted this treatment. He gives three varieties: stellatarostrata; crinita.
He described var. crinita from open hillsides and rock crevices @ 1520-2290. That is by far the highest elevation any taxon of Osbeckia

recorded from Bhutan or Sikkim but still 1400m lower than 3700m!


The post I have copied for opinion is from some other member
of our group. I am also enclosing page from the Flowers of India further reference.

I am happy to note the elevation difference. I will peruse it and publish it if the altitude difference is so significant. Thanks for the lead.
These areas are not fully documented and there is still a lot more we can learn from further expeditions.

Now lets focus on answering whether the plant I photographed is indeed Osbeckia stellata or some other Osbeckia species etc.
…, I am posting my images (attached here):
a) for identity confirmation
b) for altitude discussion [I am sure these images were taken beyond Phedang, 3000 m approx,, so even in a worst case scenario the elevation is 3000+ m, if not 3700m. Even then it is way beyond its known elevation.]
c) I also have habitat images with some neighboring ferns, some general shots of the surroundings etc..plus with a couple of not so good images of a bird and frog nearby at that height.

a, b, and c above are essentially in response to … negative assumptions in his (direct) e-mail to me.

I have referred to a couple of books published in Nepal by authentic publications including the Government of Nepal publication and all publications says the elevation for this plant is as 800-2600,1300-2600 mt. whereas FoI says 200-2300 m and Polunin and Stainton says 1200-2400 mt.

Flower for Id pl.
Location – Cherrapunji

Date – 16.10.2016


It is Melastoma species


I am in agreement that it is a Melastoma and not Osbeckia which is the commonest genus of the Melastomataceae encountered along the Himalaya –there is a line drawing of O.stellata in ‘Flora Simlensis’ showing the stamens all similar 8-10 which helps to distinguish the genus from Melastoma which has stamens of two kinds; 5-7 longer with purple anthers & 2 yellow swellings plus 5-7 shorter with yellow anthers.  This characteristic is difficult to see in the single image not in close-up from Cherrapunji.  Other differences include the feathery-haired calyces which can be seen or at look sufficiently different to those of the main Osbeckias from the region.
In ‘Flowers of the Himalaya’ it says there are two species of this genus in the Himalaya. ‘Enumeration of the Flowering Plants of Nepal’ lists M.malabathricum and M.normale – with the former species recorded from Tropical Himalayan foothills around 200m.  Whereas the latter 900-1800m.
As does ‘Flora of Bhutan’ – though the differences in the key are minimal.
But it comes as no surprise to find that M.normale has been relegated to a synonym of Melstoma malabathricum.
I think I probably saw this ten years ago during my only visit to the Meghalaya a decade ago (I was hugely disappointed that it did not rain when I was there) close to wonderful Nohkalikai Falls.

It thus


I hope it was understood that I considered the specimen to be Melastoma melabathricum – I have minimal knowledge of the local
flora in this region. There appears to only be this species now?

I see this would be the first image for this group from Meghalaya.


Thanks, … Is this also a Rhododendron variety ?


No, …


looks like Osbeckia cupularis….


I am confused by this suggestion.  Do you mean the flower named as a Melastoma? If not, kindly send images I can view.
Osbeckia cupularis is currently not an accepted name. Do you have links to up-to-date references?
It is within ‘Flora of British India’ as a species from S.India/ Sri Lanka only with dark purple or whitish flowers.

It’s the same thread in discussion- the pink flower “copy of Meghalaya 188′ posted. I read on Google that Melastoma melabathricum is also known as Indian Rhododendron hence asked the question.


Thanks for information. I understand now.
It illustrates the problems (and often confusion) caused by common names which are applied differently in different regions of a country or parts of the world.
My understanding of ‘Rhododendron’ is a plant belonging to a genus within the Ericaceae family. Whereas ‘Melastoma’ belongs to the Melastomataceae family – which are not similar, so as a botanist this common name seems incorrect to me.
In the UK, the common name “bluebells” is used in England for a completely different plant, belonging to a totally different family compared to its use in Scotland.
I recently read the paragraph in ‘Supplement to Flowers of the Himalaya’ by Stainton about the use of Latin names despite the indisputable fact that it is the only universally valid (and accepted) way of referring to a plant.
I fully endorse this as I can communicate with botanists is Japan, Russia, Norway or wherever who have minimal English using Latin names.
Anyhow, the main point is that Stainton stated that when describing Himalayan flora English names can be applied only where the species also occurs in Britain or where it is so well-known as to have acquired an English name even though it does not grow there. 
After publication of ‘Flowers of the Himalaya’ some regrets were expressed that no vernacular names had been included. The difficulty being that more than one language is involved, not only Hindi and Nepali, but also the various Tibetan dialects, the Nepali caste languages, Kashmiri and doubtless other variants as well.  And even among speakers of the same language the name used for a plant may well differ from one area to another.  To have included vernacular names in the text would therefore have been a task to tax the skills of a trained philologist!
Definitely, the inclusion of as many local names in addition to the Latin names (which are troubling enough with so many changes) is valuable and informative for efloraofIndia, hopefully helping to engage with more people.

I regularly lecture about my travels in the Himalaya (telling them it is Himalaya and not Himalayas) to clubs and societies interested in garden plants.  Many struggle with Latin names so I used common names as well when they exist but it is essential to use the Latin ones.


I think this should be Osbeckia stellata as per keys and images herein.
