Identification of Lepidagathis sp. : 8 posts by 4 authors. Attachments (3)
Pl. help me to identify the Attached Lepidagathis sp.
Erect herb- Flowers solitary in axle. Leaves entire with spiny tip. Bracts spiny. Flower cream colour.
Observed at Palladam, Tiruppur Dist, Tamilnadu on 19-07-15
Specimen do not match with L. fasciculata due to absence of crenate leaves and short spike inflorescence.
It may not be L pungens  – due to absence of spiny leaf margin.
May not be L.incurva due to absence of terminal short spike of inflorescence.

This is an interesting plant; I never came across.


After detailed net perusal, the possible nearest match is Lepidagathis fasciculata (Retz.) Nees. 


It is not L. fasciculata as the leaves in the posted pictures are spine-tipped.


Thank you …


I think it is Lepidagathis barberi as per GBIF– specimen 1 and specimen 2

Looks different from Lepidagathis rigida as per GBIF– specimen 1 and specimen 2


Lepidagathis pungens Nees ??


No, it is different as per images at Lepidagathis pungens Nees

I thought you both are the same …,

L. barberi (= pungens).


Yes …, Lepidagathis barberi Gamble is the accepted name with L. pungens Nees as its synonym.


They may not be the same.
Probably L. spinosa


This has been identified as Lepidagathis barberi as per images and details herein.
