Hi, this is Solanum indicum (= S. anguivi), i think (to be different!!).

DEAR ALL,

Please let us come into a decision regarding the specific epithet of this particular plant. Let us all supplement our responses with morphological points; i.e why you call calling this plant belonging to the partical species of Solanum sp [ diagonistic feature of the species]. It will help us all to get into a conclusion and decipher the cprrect name of the plant.

Friends, It can not be Solanum Indicum because, the fruits in the case
of Solanum Indicum turn to black (almost colour, as seen in the
picture in the link given below). Whereas Solanum Viarum Dunal is
green in colour with white lines and it turns to red when it ripens.
Please go through the links sent earlier. Please also go through the
link sent today to confirm that it is not solanum Indicum.

Dear Yazdy ji,

you have a valid point to share. let wait for other responses.

I have the following observations

The plant can't be Solanum xanthocarpum which has subsequently been named as S. surattense and now correctly as S. virginianum, because that plant is a small spreading subshrub with leaves not velvety.

The name S. indicum applied to Indian plants is not valid. Some of Indian Plants i.e. S. indicum auct with glabrous fruits is correctly S. anguivi, S. indicum L. now correctly known as lasiocarpum has tomentose berries.

   S. verbascifolium L. now correctly known as S. erianthum has unarmed stems and leaves.

I think the toss is between S. viarum and S. anguivi:

 Solanum viarum Dunal in A. de Candolle, Prodr. 13(1): 240. 1852

Syn: Solanum khasianum C. B. Clarke var. chatterjeeanum Sen Gupta.

Herbs or subshrubs, erect, 0.5-1(-2) m tall, armed, minutely tomentose with many-celled, simple, mostly glandular hairs. Stems and branches terete, densely and evenly pubescent with many-celled, simple hairs to 1 mm, armed with recurved prickles 2-5 × 1-5(-8) mm and sometimes with needlelike prickles 1-4 mm. Leaves unequal paired; petiole stout 3-7 cm, armed with erect, flat straight prickles 0.3-1.8 cm; leaf blade broadly ovate, 6-13 × 6-12 cm, with prickles and coarse, many-celled, glandular simple hairs on both surfaces, these mixed with sparse, sessile, stellate hairs abaxially, base truncate to short hastate, margin 3-5-lobed or -parted; lobes blunt at apex. Inflorescences extra-axillary, subfasciculate, 1-5-flowered racemes; peduncle obsolete or short. Flowers andromonoecious, only basal ones fertile. Pedicel 4-6 mm. Calyx campanulate, ca. 10 × 7 mm, lobes oblong-lanceolate, 0.6-1.2 mm, hairy and sometimes prickly abaxially. Corolla white or green; lobes lanceolate, ca. 2.5 × 10 mm, pubescent as on calyx. Filaments 1-1.5 mm; anthers lanceolate, acuminate, 6-7 mm. Ovary puberulent. Style ca. 8 mm, glabrous. Berry pale yellow, globose, 2-3 cm in diam. Seeds brown, lenticular, 2-2.8 mm in diam. Fl. Jun-Aug, fr. Jun-Oct.

Wastelands, grasslands, thickets, open forests, along ditches, roadsides; 1400-2200 m. E Xizang (Zaya Xian), Yunnan [widespread in tropical Asia and Africa].

A prickly undershrub, 1.5-2 m tall, with dense stellate-tomentose parts. Prickles up to 10 mm long, erect to slightly recurved. Leaves 4-15 x 3.5-9 cm, ovate to oblong-ovate, repand, acute, both surfaces stellately hairy and prickly on the nerves. Petiole up to 2.5 cm long. Flowers 4-15 in number, bluish-purple, in extra-axillary cymes. Calyx ± 4 mm long, campanulate, stellately hairy. Corolla limb 18-20 mm broad; lobes acute. Anthers 6-7 mm long; filaments glabrous. Ovary and style pilose-pubescent. Berry globose, (5-)8-10 mm broad, glabrescent, yellow. Seeds ± 3 mm long, subreniform, minutely reticulate, foveolate.

I would go with S. viarum on the basis of longer petioles and prickles on leaf surface.

Dear All,

On the basis of the relevant taxonomic characters discussed by Yazdy Ji & Gurcharan Ji we all can come into a positive conclusion that "The plant in the attached photographs belong to the genus Solanum sp and its specific epithet is Solanum viarum". I personally thank all of you for taking the tedious effort and well planned techniques to decipher the name of this long discussed plant from West Bengal brought into our notice by Mr. Sibdas Ghosh.

 

THANKS TO ALL

Dear Friends,
I am not very sure now, because since posting my last mail, I have
seen pictures of ripe fruits that are yellow in colour, but the
fruits I have seen in my farm is of fruits that are red in colour.
We may have to wait a while and study a bit more.
Regards
Yazdy Palia.

Dear all,

The flowers in Solanum viarum Dunal are usually white and the fruits (small wild brinjals,some 3 cm across?) are used as vegetable by local people in TN. Plants are smaller when compare to S. anguivi (= S. indicum). So the pictures shared by Sibdas ji must be Solanum anguivi (shrub 1-1.5 m high, with fruits of about 1 cm) and not S. viarum. He may like to provide more pictures for better understanding.

[sibdas ghosh]

Taking the clue from Gurcharanji, I am attaching some more photos,

one of them (100_1031 JPG) was sent earlier which I labeled as S.xanthocarpum/ surattense, but did not get any response from others. The other (100-1137-1) was also sent earlier . It was identified as  S.viarum. If that is a viarum, the present one is likely anguivi- waiting comment from Gurcharanji- Sibdas Ghosh

Dear Sibdas da,

attached photo is of 2 different plant first and last one is of Solanum torvum (100_1031 JPG & 100_1137-1.JPG) and the middle one is S surattense (100-1137-1) . please see the leaf morphology and you will understand that i am correct .

You seem to be getting confused with long thread. First photo is same as first in original set above, only that flower is clearly seen. As Sibdas ji has pointed out ( and earlier Vijayasankar ji) it is S. anguivi. Third one seems to be S. viarum, as suggested by Sibdas ji. Second one with highly dissected leaves and paniculate white flowers is definitely not S. xanthocarpum(S.surratense correct name S. virginianum). This perhaps is still unidentified and needs further critical examination.

[R. Vijayasankar]

The second picture (100_1031) with white flowers and dissected/lobed leaves probably belongs to Solanum sissimbrifolium.

[Gurcharan Singh]

Yes Vijayasankar ji

Seem seem to have solved the riddle ultimately.
