This should be S. violaceum
S. anguivi has mostly white flowers, less than 12 mm across, in many-flowered raceme like cymes.

Sir,

I must have missed some characters. I need to refresh my solanum collection. I will upload more species later.

FoP must have updated their site after your key in - https://groups.google.com/d/msg/indiantreepix/7070VSdNpTs/ewa6R-1k_-YJ

FoC has S. violaceum Ortega - with shiny orange berry, which is similar to S. anguivi Lam. of FoZ.

Flora indica, vol1, p570 informs -
S. indicum Willd. sp. i. 1042 (i don't know it's meaning) - berries erect, round. smooth.... while immature variegated with deeper and lighter green, when ripe with deep orange yellow.

Thank you

Regards,
suraji

Good morning Sir,

This plant is not Solanum anguivi Lam. as per Flora of Zimbabwe and your post & discussion at - https://groups.google.com/d/msg/indiantreepix/dSZcm0MK01c/p_liC6fnl4YJ & https://groups.google.com/d/msg/indiantreepix/7070VSdNpTs/hWiljeLiSJ4J

KEY to Solanum in eFI informs S. violaceum Ortega is an unarmed shrub : 15a > 16b > 19b > 20b !!! This goes against the thread - https://groups.google.com/forum/#!msg/indiantreepix/dSZcm0MK01c/p_liC6fnl4YJ, both on 'arm' and 'flower size'.

Attached here sub-reniform, foveolate seeds of this plant.

Thank you

Surajit ji
Stem in S. violaceum has curved prickles as per our regular key on the website. I can't now figure out how I added S. kurzii as synonym of S. violaceum. I have removed that now. But then S. kurzii is an East Himalayan species, fruits uploaded by Ritesh ji once as Tita Baingun. Perhaps you can explore it further.

Good morning Sir

Thank you for the updated KEY. Interestingly GRIN thinks Solanum kurzii Brace ex Prain is synonym of Solanum violaceum Ortega.

I think I must have followed GRIN in putting S. kurzii as synonym after constructing the key. Perhaps original description of S. kurzii should help.

I looks both synonyms given by GRIN have problem. S. violaceum clearly has curved prickles as indicated in both description of Flora of China


Important also that it includes some specimens originally included under S. indicum in earlier Floras.

Good morning Sir

I have read and re-read FoC description of S. violaceum Ortega many times. Herbarium of S. violaceum clearly shows prickles -

This is confusing, for earlier I thought my plant was closer to S. anguivi Lam. of FoP., even though it doesn't have many flowered racemes. But at the same time my plant neither have 'scorpioid raceme' (?) of S. violaceum of FoC. Of-course 'Prota.org' have different version of Solanum anguivi.

Thank you

Regards
!

The confusion is justified, as both S. anguivi and S. violaceum have S. indicum as snonym in one form or another, obviously not very different species. Perhaps any recent book which lists both can give a better and conclusive key.

Thank you Sir.
Solanum erianthum D. Don (S. verbascifolium non L.) is another species which was entered, in Hooker, Prain and Haines as S. verbascifolium L. But, S. verbascifolium L. is regarded as S. donianum Walp., by GRIN and FoC.

Yes Surajit ji, the plant identified as S. verbascifolium in Indian works is S. erianthum D. Don, as clarified in several threads of of efloraofindia

Yes Sir, I have noted our group site posts. I was thinking what could be Ritesh Ji's plant, which looks somewhat like http://www.ethno-botanik.org/Nutzpflanzen/Solanum_aethiopicum/Afrikanische_Aubergine_Solanum_aethiopicum.html, impossible though!

Thank you very much.

Regards
