I am confused between Uncaria scandens and Uncaria sessilifructus as per images and details herein.

Pl. check with the descriptions and keys in Flora of China. also check the following:

https://www.gbif.org/species/5338202

Seeing the fruits I am more inclined towards Uncaria scandens (Fruiting head 20-25 mm in diam. Fruit sessile, obovoid to oblanceoloid, 6-9 mm, hirtellous) than Uncaria sessilifructus Roxburgh (Fruiting head 25-35 mm in diam. Fruit sessile, fusiform, 10-14 mm, sericeous)

Flora of china Garg Ji,

With regards.

[J.M. Garg]

Thanks, Paradesi ji,

How about fruits ?:

Uncaria scandens (Fruiting head 20-25 mm in diam. Fruit sessile, obovoid to oblanceoloid, 6-9 mm, hirtellous) than Uncaria sessilifructus Roxburgh (Fruiting head 25-35 mm in diam. Fruit sessile, fusiform, 10-14 mm, sericeous)

[J.M. Garg]

Uncaria scandens (Fruiting head 20-25 mm in diam. Fruit sessile, obovoid to oblanceoloid, 6-9 mm, hirtellous- stipules deciduous, ovate, 6-10 mm, deeply 2-lobed, strigillose, puberulent, or glabrescent,  lobes lanceolate, ovate, or narrowly triangular, acute) than Uncaria sessilifructus Roxburgh (Fruiting head 25-35 mm in diam. Fruit sessile, fusiform, 10-14 mm, sericeous- stipules deciduous, ligulate to lanceolate, 7-10 mm, 2-lobed for 2/3 or more, glabrous to densely puberulent, lobes narrowly triangular, acute).

From the above, I have the feeling nthat there is not much difference in the stipule lobes. Pl. check and let us know.

[Paradesi Anjaneyulu]

Garg Ji, how can we measure to the fruits and shape too, there is not clearly a single fruit, there is only clumped fruits with inflorescence, that's why only I took which character(stipules) differentiate with photos. 

with regards.

[Paradesi Anjaneyulu]

Nidhan Ji, please check with which provide information Garg Ji if you have material, 

then finalize species,

With regards.

[J.M. Garg]

Hi, Paradesi ji,

PL. see the shape of the fruit in Uncaria sessilifructus at

http://www.efloras.org/object_page.aspx?object_id=119538&flora_id=2

It looks quite different compared to those posted by Nidhan ji.
