Place: Agumbe, Karnataka

Habit: Small shrub
Flowers: Around 2-3 cm across.
Leaves- 3-4 cm in length
Reference: 1) Attached along with photos and 2) http://www.kew.org/herbcatimg/448072.jpg
The combination of 3-ribbed leaves and tuft of bristles on an elongate stalk on the calyx cup led me to O. octandra (Image title ‘3’). Please validate. And in case it is any other species of Osbeckia, I have attached the remaining key to 5 petal Osbeckia sp (‘1’, ‘2’ and ‘3’).

Based on this single images, it appears to be incorrect.


May I request you to give your views in this matter pl.  


Osbeckia octandra sensu Clarke, is distributed only in Sri lanka, Ceylon. In FOI all images shown under Osbeckia octandra is Osbeckia virgata D. Don ex Wight & Arn. 

Osbeckia virgata and O. octandra are closely related. They are easily recognized from other species in their area by their general appearance. But they may be confused with O. brachystemon, O. parvifolia and O. moonii when one has to decide their identity by means of differential characters. O. virgata and O. octandra differ from these by the usually much sparser vestiture of the hypanthium; by the almost thread-like intersepalar emergenoes with 1 to few bristles, or by the much reduced intersepalar emergences; and by the deciduous sepals.

I am attaching few images

That’s right. Osbeckia octandra is found only in Sri Lanka. So, the FOI specimen must be Osbeckia virgata.
