I think … plant is Lecanthus obtususwhich was for long considered a synonym of L. peduncularis, but is a much shorter, delicate herb, with short peduncles. I am attaching the original description and drawing of Lecanthus peduncularis var. garhwalensis, which is now a synonym of Lecanthus obtusus. On my recent visit to Dhanaulti, I saw Lecanthus peduncularis growing in great numbers and realized how robust a plant it is. That made me relook into the much shorter and delicate plant we had also found earlier. Leaves of L. peduncularis are acute to acuminate, never obtuse as seen in … plant.


Thanks Tabish, for pointing to Lecanthus obtusus (Royle) Hand.-Mazz. – it has very limited distribution in India – endemic to Himachal Pradesh, Jammu & Kashmir, Maharashtra, Uttarakhand.
Hoping that … and other friends familiar with this genus will give their thoughts and resolve the ID.

Pl. check with GBIF specimens of Lecanthus obtusus from Nilgiris (one and two).


Yes, the herbarium specimens agree with my understanding of Lecanthus obtusus. The leaf margins in this species vary from being toothed to being almost entire. I think Dinesh’s plant agrees with this species. Prominent features are the small size of this plant, and the short peduncles. I am attaching an image of a typical Lecanthus peduncularis plant to contrast it with.

What about this one …? Same Lecanths sp.?


Appears to be the same plant as at SK 2818 03 November 2020


I think this is Lecanthus obtusus, a dwarf plant much smaller than Lecanthus peduncularis
I had posted about it HERE earlier.


Yes, … That is why I tried to obtain your opinion.

How can we establish? This would be a new sp. for Nepal.


It is known from East and West Himalaya. So it is not surprising that it is found in Nepal too.


Need to work out on this


Checklist of Nepal already gives Lecanthus obtusus (Royle) Hand.-Mazz. as a syn. of Lecanthus peduncularis (Royle) Wedd.


Yes, that is there but it has not been updated and most of the databases like POWO, GBIF, CoL, IPNI and WP have mentioned this  as different sp. Even the book by KK shrestha et all have not synonymized this sp.
