ANMAR34/54 Please identify this herb : 7 posts by 3 authors. Attachments (6)

Family: Rubiaceae
Date: November 2014
Place: Nelliyampathy, Palakkad, Kerala

Habit: Herb
Habitat: Grasslands

The stipules are pectinate. They are cut up/divided. Please see the attached photo.

Using this feature and referring the Hassan flora, I can narrow down to the genera Neanotis, Oldenlandia, Knoxia, Borreria and Mitracarpus (please see attached photo again).

I cannot go further as I do not know the nature and number of ovules and locules of the ovary in the plant I have photographed.

Neanotis sp?

Neanotis species in eFIoraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ efloras/ books etc., where ever available) 

I guess it is Knoxia mollis (synonym of K. sumatrensis).

Thanks sir. Knoxia sumatrensis.

On 17/8/08 in Talakona forest, AP near Tirupati.

is it some Callicarpa sp

Does not matches with any Callicarpa species so far in efi.

Knoxia wightiana Wall. ex G.Don ??

it is Knoxia sumatrensis very common here

Thank you …! I was thinking between these two !

I too agree with ma’am, sure it’s not wightiana,


Please help me for the identification of some Hedyotis species collected recently (19.12.13) from grasslands in Kerala, above an altitude of 2100m.

This may be Hedyotis eualata (Gamble) Henry & Subram.

Hedyotis eualata is different.  

Hedyotis auricularis ??

No. Different.

Exallage auricularia (L.) Bremek. ??

Knoxia sumatrensis, perhaps.
