Family : Rubiaceae
Genus & species : Spermacoce remota Lam. (??)
Habitat: Grows wild on hilly slopes
Habit : Herb
Flower : White in colour
Fruits : Not seen efi page on Spermacoce remota ?
I think it should be Spermacoce pusilla Wall. as per comparative images at Spermacoce and as per keys at Flora of China I mean here S.remota is correct. Thanks, …,
I do not think it is Spermacoce remota as per images and details & references herein.
After through search in Flora of China, Flora of Nepal, Efi site etc., I feel it is closer to Scleromitrion tenelliflorum (Blume) Korth. (syn: Hedyotis tenelliflora Blume) as per
On further checking, I think it should be Scleromitrion verticillatum (L.) R.J.Wang (syn: Hedyotis verticillata (L.) Lam.) as per differences between closely related species at
cleromitrion sirayanum (Rubiaceae: Spermacoceae), a new species of the Hedyotis-Oldenlandia complex in Taiwan (hispidulous calyx) and as per GBIF (high resolution specimens) FOC illustration Flora of China
Dehradun-Mussoorie Tour 2013:: Rubiaceae Herb for id from Dehradun : Attachments (5). 5 posts by 3 authors. It may be Metabolos rugosus (= Hedyotis rugosa). Not sure though. After through search in Flora of China, Flora of Nepal, Efi site etc., I feel it is closer to Scleromitrion tenelliflorum (Blume) Korth. (syn: Hedyotis tenelliflora Blume) as per
Catalogue of Life Flora of China FOC illustration GBIF (high resolution specimens)
Hedyotis rugosa (Blume) Korth. does not have any distribution in India. On further checking, I think it should be Scleromitrion verticillatum (L.) R.J.Wang (syn: Hedyotis verticillata (L.) Lam.) as per differences between closely related species at

Thanks … for providing useful links, I do agree that it is quite difficult to conclude based on these pics only..

Does not seem any Spermacose (Borreria) listed in the ACFPN.
Some thing similar was identified while I was sorting out Spermacoce species under Spermacoce pusilla as Oldenlandia ?
However, I am not able to get hold of that post or species right now. It resembles Oldenlandia nitida, Pl. see Hedyotis neesiana
Please see this old post of mine… I think they are similar.. but the id was not resolved
It looks like very much matching with your images but not sure about the ID,
and it is not listed in Nepal. How can we verify?

Hedyotis rugosa (Blume) Korth. does not have any distribution in India. It is quite like to be found in your area as WCSP shows distribution as Trop. & Subtrop. Asia to N. Queensland. Catalogue of Life gives it as Assam; Bangladesh; Borneo; China South-Central; China Southeast; East Himalaya; Hainan; Japan; Jawa; Korea; Malaya; Maluku; Myanmar; Nansei-shoto; New Guinea; Nicobar Is.; Philippines; Queensland; Sumatera; Taiwan; Thailand; Vietnam
… has posted the same plant from from Malsi Deer Park, Mussoorie Road, Dehradun Here is a paper showing differences between confusingly similar species Scleromitrion angustifolium (Cham. & Schltdl.) Benth. is treated as a syn. of Scleromitrion tenelliflorum (Blume) Korth. in Catalogue of Life; On further checking, I think it should be Scleromitrion verticillatum (L.) R.J.Wang (syn: Hedyotis verticillata (L.) Lam.) as per differences between closely related species at Thank you … for validation !

Spermacoce ?? Check Spermacoce pusilla I think close to images at Scleromitrion verticillatum Yes … You are right ! I think leafing pattern looks different from Scleromitrion verticillatum (L.) R.J.Wang ! I do not think so. .
