as per Catalogue of Life;
Keys as per Flora of China:
Leaflet margin entire, sometimes ciliolate; leaves 2- or 3-pinnatisect, terminal leaflet narrow.   9 B. bipinnata
Leaflet margin prominently serrate; leaves subpinnately divided, terminal leaflet broad, ovate.   10 B. biternata

Spanish Needles, yellow flowered blackjack, black jack, five leaved blackjack, beggar ticks • Hindi: चिर्चिट्टा Chirchitta;
 
Tall annual herb with subpinnately divided larger leaves with broader serrate leaf segments, terminal largest, ovate; involucre bracts with dilated tips; ray florets yellow. 
 
The species Bidens biternata is distinct from B. pilosa in much smaller number of florets, linear involucre bracts which are ciliate (nearly spathulate and glabrous in B. pilosa)

Leaflet (segment) margin is prominently toothed/serrate, so it should be B. biternata. Also leaves are less divided with large terminal segment. In B. bipinnata leaves are twice to thrice pinnatisect with entire leaflet (segment) margin. Both lack rays or may have up to 5 yellow ones, they are white and prominent in B. pilosa.

Herb for Id- 041109Jm1: On 11/10/09 along roadside in Ananthagiri HIll forest in Rangareddy district of Andhra Pradesh.


This is Bidens pilosa (Asteraceae). Pl. also check it for B. biternata.


Thanks, …
I think it’s Bidens biternata as per FOI link & indiantreepix thread:
http://www.flowersofindia.net/catalog/slides/Spanish%20Needles.html (Closely related to B. pilosa, but can be distinguished by the leaves, which are usually 5-7 foliolate, with the lowermost pair redivided into two to three segments)

It is B biternata. The species is distinct from B. pilosa in much smaller number of florets, linear involucre bracts which are ciliate (nearly spathulate and glabrous in B. pilosa)


Am uploading pictures of Bidens pilosa.


In my search for wild plants, weeds that are also edible, I found that Bidens Pilosa is a pot herb.

I would like to know if anybody has actually used it and more details on its usage.

Bidens biternata from Ajinkyatara Satara.
