It is my pleasure to share a few images of Hoya wightii (Apocynaceae) said to be endemic to Peninsular India.

Habit: Epiphytic, shrub

Habitat: Evergreen forest
Sighting: Sakaleshpur, Hassan, Karnataka, about 1200 msl
Date: 17-08-2015

Please help me in distinguishing this species from the closely related Hoya ovalifolia Wight & Arn., occurring in the same area and having leaf-margins not recurved and the corona lobes concave above.

Please compare it with Hoya ovalifolia which seems more probable for the above mentioned characters.

efi page on Hoya wightii & no page as yet on Hoya ovalifolia  

Seems to match with images of Hoya wightii at FOI
Does not match with Hoya ovalifolia at hoyor net

Regarding Kannada names: ಅಂಬ್ರಿ ambri, ಪೀಪಿ ಬಳ್ಳಿ pipi balli.  For me it looks correct. English transliteration for ಪೀಪಿ ಬಳ್ಳಿ  is Peepi balli
