Cyperus plateilema (Steud.) Kük. (=  Mariscus bulbosus Steud), wild sedge from Denkanikota area of Krishnagiri District Tamilnadu


Thank you very much for sharing. Can you please tell me how to differentiate this one and 1) Cyperus paniceus (Rottb.) Boeckeler 2) Cyperus cyperoides (L.) O. Kuntze?


One of my earlier upload which seems similar to your species (Cyperus plateilema (Steud.) Kük.). So please confirm and validate.


I am afraid your sedge doesn’t look like the herbarium found in KEW –
What we have in India is Mariscus bulbosus C.B.Clarke (not of Steud; vide FBI.vi.620) (please check http://www.iucnredlist.org/details/176908/0 for distribution) ….. which is somewhat similar to Mariscus pictus Nees (vide FBI)…. I am not sure if your plant can be same.

The KEY, to identify C. paniceus and C. cyperoides, is different in the book “Bengal Plants” and in FBI, which does not tally with what you have provided here.

I have one post. KEW has several herbaria
  • C. cyperoides (spike not always oblong? spikelet 1 to 3 flowered)
  1. http://apps.kew.org/herbcat/detailsQuery.do?barcode=K000362749
  2. http://apps.kew.org/herbcat/detailsQuery.do?barcode=K000321389
  • C. clarkei (I do not know,  as per FBI stem 3-8 inch….since your spikes are subcapitate or with short rays it maybe…)
  1. http://apps.kew.org/herbcat/detailsQuery.do?barcode=K000290886
  2. http://apps.kew.org/herbcat/detailsQuery.do?barcode=K000592556

As for “glumes”, “wing”, “spikelets”, “florets”….. these are all Greek to me and I have never tried to examine them under microscope, for I know I won’t understand.


I agree with Cyperus clarkei C. Cooke, as identified by …


Plant specimens have to be studied for correct identity. Can be a variant of Cyperus cyperoides (L.) Kuntze, a highly variable species.

ID of Cyperus sp. from Assam KD 04 Oct : 3 posts by 2 authors. Attachments (5). Attached images may be Cyperus cyperoides (L.) Kuntze or Cyperus clarkei T.Cooke. Please ID the plant. Date :06.10.14 & 07.10.2014 Location: Assam Family : Cyperaceae. Genus & species : Cyperus cyperoides (L.) Kuntze or Cyperus clarkei T.Cooke. Habitat: Grows wild on hilly area


Seems to be a variant of Cyperus cyperoides (L.) Kuntze. Need a specimen to confirm the identity 


BSI doesn’t list Cyperus cyperoides (l.) Kuntze. Instead, it is regarded as synonym of Mariscus sumatrensis (Retz.) Raynal. Another synonym of the taxon is Mariscus siberianus Nees ex C. B. Clarke.Given that it has been identified so can you please tell me if this species is same as in your another thread ?


I didn’t find any attachment with your mail. If it is of the nomenclature problem, the current name for Mariscus sumatrensis (Retz.) Raynal and Mariscus siberianus Nees ex C. B. Clarke is Cyperus cyperoides (L.) Kuntze, because Mariscus is now treated as Cyperus. In some earlier publications of BSI this species might have appeared under Mariscus, because in those days that was the correct name, but now these are synonyms of Cyperus cyperoides (L.) Kuntze


Thanks, … Pictures are at link


The plant image downloaded from the link is of Cyperus cyperoides (L.) Kuntze


I placed the question before …, and actually the question was if his thread is same species (not necessarily same specimen) or not.


Sorry for late reply. Actually I collected both the specimen from different locality and in different months( one in the month of May and other in the month of October). My second specimen (collected inthe month of October) may be variant of Cyperus cyperoides. So expert will identify & validate.


Well, Sir, I attach a couple of shots i recorded today, a less than 1 ft herb in a bamboo thicket. It looks similar to your uploads in this thread.
Earlier I had identified a similar looking species as C. paniceus in thread.
I am still confused between the two species. Both are distributed in your area as well as in our area.
Somebody has to crack the difference between the two. My guess is that (1) cyperoides spikes are dense (2) at least some spikelets should be two flowered (3) plant should be a bit stouter than paniceus.
The problem aggravates by the fact there are var. in both the species, and one more taxon cyperinus need to be considered.

Thank you … Thanks to … I wish if … could upload macro of spikelets of this species. I also wish to know the differentiating characters between C. cyperoides and C. paniceus so that I could determine my species.

I do not have macro images of my species collected from Assam. But I have visited Meghalaya on 03.10.15
where fortunately I have collected the same species (?). Here I attached the images of those
species. Hope this will help you.

Sir, as you know I am trying to tread a path where only a few members dare to express their opinion! I take advantage of the fact that i have nothing to lose!
Well, i think the spikelets here are different than what i have here. 4th and 5th pics in this set indicate presence of more than one florets per spikelet. So, your new find won’t be C. paniceus, i think would be C. cyperoides.
But, here is a problem, number of spikelets per spike is less than what has been described in FoC or FoP. Given that C. cyperoides is a very variable (please check endnote in FoC) species i think i would select C. cyperoides for this one.
We should wait for view of … and/or others.
Thank you very much for taking care.


Sir, please do not mind, my assumption is based on the marked spikelets of your resized photograph no.5.

Cyperus sp. from Kamrup district, Assam : Attachments (4).  4 posts by 3 authors.
Attached images are Cyperus sp. Please ID the species.
Date :30.05.2013
Location: Kamrup district
Family :Cyperaceae
Genus & species : Cyperus sp.
Habitat: Grows wild wild on waste places
Habit : Herb

One cyperaceae, Mariscus sieberianus Nees (http://www.theplantlist.org/tpl/record/kew-254024 ?) looks similar.

Other similar looking –
  • Mariscus cyperinus Vahl
  • M. pictus Nees
  • M. paniceus Vahl

Also pl. check images at Cyperus paniceus (Rottb.) Boeckeler, Cyperus clarkei T.Cooke & Cyperus cyperoides (L.) Kuntze 


It looks like Cyperus cyperoides

This Cyperus sp. was shot from Panipat?..I have a single shot..please id if possible…


I think its Cyperus cyperoides (L.) Kuntze.

Cyperus paniceus


Thank you …! Cyperus paniceus (Rottb.) Boeckeler

This link contains several species of Cyperaceae.


Looks like Cyperus cyperoides (L) Kuntze


I guess … is correct! Looks like Cyperus cyperoides (L) Kuntze

Poaceae, Cyperaceae and Juncaceae Week: Cyperaceae- 05042013GS3 Cyperus for ID from Kashmir-GS43 :
Tall Cyperus species growing along Nagin lake in Kashmir. Kindly help in ID.

Pl. also check with images at Cyperus squarrosus L.


It may be helpful to know what Stewart had recorded about Cyperus squarrosus.
He found it from what was the North-West Frontier Province through Swat & Hazara to Ladakh (so I have a special reason to familiarise myself with this species – it is the only member of the genus known here) also as common Kashmir incl. Lidderwat & Pahlgam, though Srinagar/the lakes are not specifically mentioned; 1200-2700m.
Unfortunately, I have a description of this species from Bhutan and Sikkim- here it is a dwarf plant to 15cm at most, typically on mossy boulders, damp roadsides, fields, arable weed. The herbarium specimens at Kew support these dimensions, so this species seems highly unlikely.
Have had a quick look at information about 5 Cyperus recorded from the lakes (all sounded promising) or nearby in Srinagar but 4 definitely do not fit; the other I cannot find an accepted name to check it out. Stewart knew it as C.globosus (syn. C.capillaris). Perhaps you can track down what its current name is and whether it is a possibility?
I am a complete beginner with Cyperus – we only have 2 species in UK and they are not common. Rather more to consider in the Himalaya/ India. Stewart lists close on 50 species from Pakistan & Kashmir….

Can be Cyperus cyperinus, need a specimen to confirm the identity.


I know very little about Cyperus but worth mentioning that Stewart did not record tis from anywhere in Pakistan or Kashmir, though did say “To be expected in Jammu”.

PLANTS FROM GUJARAT
CYPERACEAE


I think its Cyperus cyperoides.


I do not know how to differentiate a Cyperus cyperoides from a Mariscus paniceus (Rottb.) Vahl (Cyperus paniceus). One interesting find is that while IUCN informs that the later can be found in Gujarat (http://www.iucnredlist.org/details/176887/0), the former finds no mention in IUCN list – http://www.iucnredlist.org/details/177276/0.


Again I am confused between the two – Cyperus cyperoides (L.) Kuntze and Cyperus paniceus (Rottb.) Boeckeler :-


It is Cyperus cyperoides (L) Kuntze
