Rubiaceae Week:: Ixora Sp. for ID from Mullem WLS, Goa:
Seen this Climbing Shrub at Mullem WLS, Goa. Leaves opposite with very short petioles.
Bot. name: Ixora Sp. (ID requested).?
Family: Rubiaceae
Date/Time: 23-04-2011 / 12:15PM
Location: Mullem WLS, Goa.
Habitat: Wild

… again, possibly Ixora nigricans … please check whether this plant is similar to one you found in Chandoli WLS in all aspects.

For me it appears to be Ixora nigricans Br. (Rubiaceae). It is not a climber rather a shrub some times slender

Family: Rubiaceae

Location: Chandoli WLS, Maharashtra
Habitat: Wild

this plant is similar to the one earlier posted Chandoli WLS plant – probable ID, Ixora nigricans.

In case of Ixora ID one must give colour of dried leaves and the length of corolla.

And of the remaining species, I ruled out Ixora arborea because I have seen it before. Lastly, calyx glabrous narrowed it down to Ixora nigricans. I matched it with … earlier photos from Belgaum and later it was confirmed by him and …
