Good morning Pudji Ji,

Thank you for the ID of this plant. Would you please tell me how Kyllinga monocephala differs from K. brevifolia? The net gives confusing data -

• K. monocephala is synonym of K. nemoralis - http://www.theplantlist.org/tpl/record/kew-251362
• sometimes the above name is either illegitimate or with low confidence level - http://www.theplantlist.org/tpl/record/kew-251375

Thank you & Regards,

Dear all,

The correct name for this species is Kyllinga nemoralis (Forst.) Dandy ex. Hutch. & Dalz. (Fl. W. Trop. Africa 2:486. 1936).

Kyllinga monocephala Rottb. is an illegitimate name since Rottboel referred Schoenus coloratus L. (now Rhyncospora colorata (L.) H. Pfeiff.) as a synonym in his protologue (Descr. lcon. Rar. Nov. Pl.: 13. t.4. 1773). The next validly published name is Thryocephalan  nemoralis  J. R.  & G. Forst (Char. Gen. Pl.: 130. 1776) which became the basionym for K. nemoralis.

Dear Surajit ji

You may please use the following key to distinguish both the taxa

Key to the species

• Inflorescence of 1–3 sessile, white or greenish white globose spikes, the central spike larger than others; nut bearing glumes winged; glumes white, winged towards the distal end, wings ciliate ……......................K. nemoralis
• Inflorescence a single globose spike, green to yellowish green; nut bearing glumes not winged; glumes green, acutely keeled, keel ciliate or glabrous……………..........K. brevifolia

  There are two infraspecific taxa for Kyllinga brevifolia. A key to the subspecies is given below..

Key to the subspecies

• Glume 2.5- 3mm long with ciliate keel……………….………...….var. brevifolia
• Glume 2.0 mm long with glabrous keel……………..…………..…var. stellulata

with best regards

Sir,

Thank you very much for providing me the ID keys to K. nemoralis & K. brevifolia. But, i fail to understand the terms used in the keys. These terms are new to me. I tried and failed to learn about them using google search. I need more help on these.

Except for glume colour, i fail to sort out which of the attached pic shows the, "central spike larger than others; nut bearing glumes winged; (glumes white); winged towards distal end, wings ciliate" .... (the key to K. nemoralis).

According to eflora China - 

• Leaves usually shorter than culm ..... K. nemoralis - http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242101155
• Leaves shorter to slightly longer than culm .....K. brevifolia - http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200026870

Glume color - 

• Glumes pale to straw colored ....K. nemoralis - http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242101155
• Glumes white and rusty brown maculate or rarely straw colored ..... K. brevifolia - http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200026870

Culms -

• Culms distant or laxly tufted ......K. nemoralis - http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242101155
• Culms serially arranged, sometimes also laxly tufted .....K. brevifolia - http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200026870

Am i going completely wrong way?

Sir,

I have now by my side, a book, "BANGLAR GHAS O BANSH" (Grasses and Bamboos of Bengal) by Dr Dulal Chandra Paul.

This book, written for enthusiasts, also features some Cyperaceae members, since they are also grasses to us, the commoners.

According to above mentioned book the Kyllinga species found in West Bengal is Kyllinga monocephala Rottb., the accepted name being Kyllinga nemoralis as have been confirmed by Manudev Ji and Pudji Ji in  earlier mails.

Regards,

Surajit Koley
