Endemic to a long geographic range in the Hindukush Himalayas from Bhutan in the east to Pakistan in the west. The western limit of this species is district Swat (Khyber Pakhtunkhwa province), Pakistan. It occurs on higher elevations between 1500 and 3000 m. The habitats of the species are commonly the Himalayan moist temperate forests (evergreen forests of conifers between 1500 to 3000 m elevations), rarely subalpine or open alpine lands (above 3000 m). We collected it from open stony alpine slopes and stream side slopes in a V-shaped mountain valley.

Another plant for ID ABJUL01/38 : 9 posts by 3 authors. 5 images.

I just edited these photos from my earlier walk. I found this growing at about 2300m. The fruit was like a green chilly. Please help identify it.
Above Mcleodganj, Dharamshala, HP
2300m
09 July, 2016

It may be Cynanchum sp. (family Asclepidaceae).


Looks like an Apocynaceae.


Thank you … I saw this plant on my walk on Sunday again. There were no flowers this time but the beans were in pairs. I plucked one leaf to check for the milky sap but there was none. I am not sure what I did wrong. Perhaps I should have broken the leaf in stead of expecting milky sap from the leaf stem.


Not all Apocynaceae has milky latex. Not Asclepiadaceae is merged under Apocynaceae.


Thanks, … I think seem to match with images at Vincetoxicum hirundinaria Medik.  syn. Cynanchum vincetoxicum

Vincetoxicum canescens ABMAY01/2018 : 4 posts by 2 authors. Attachments (10)

I found this milkweed near home this time. I had photographed it earlier and posted to the group here. Revisiting the ID, I found it to be not V. hirundinaria as the description in Flowers of the Himalaya states: ‘Corolla c. 5mm across, with nearly hairless triangular lobes‘ and ‘calyx-lobes triangular, nearly as long as corolla‘ for V. hirundinria.
The plants here have hair on the inside of corolla lobes and calyx is much shorter than the corolla. The description matches more closely to the Cynanchum glaucum in Flora Simlensis: ‘Calyx about half as long as the corolla. Corolla hairy on the inner surface.
Tibetan Medicinal Plant treats C. glaucum (V. glaucum) as a synonym of V. canescens and describes it as:
Corolla yellow or green fading to greenish orange; tube approximately 1mm; lobes ovate, 2-3 x 1.5 mm, hairless outside, sparsely hirsute inside; sepals less than 1mm.’
But the authors treat it as part of the larger V. hirundinaria group perhaps because medicinal properties are similar.
FOP says: ‘Perennial undershrub, c. 15-70 cm tall, erect to twining, pubescent. Leaves 4-7 cm x 1.8-6 cm, ovate-lanceolate or cordate, glabrous to pubescent, entire, acute to acuminate. Flowers clustered in the leaf axils. Pedicels 4-5 mm long. Calyx lobes c. 1.5 mm long, lobes oblong to lanceolate, acute. Corolla c. 4 mm long, cream to greenish, lobes hairy on the inner surface. Corona lobes 5, obtuse. Follicles 5-6 x 1-1.5 (-2) cm, gradually tapering towards the tip.
Fl. Per.: June-September.
I made some measurements too:
Plants 40-80cm tall, pubescent. Leaves c. 5cm x 7cm, bottom ones smaller and blunt-tipped, hairy on the nerves underneath and on the edges. Flowers greenish-yellow c. 1cm across, 5-7 petals (lobes), smooth outside but hairy on the inside; sepals narrow c. 1.5-2mm each. Pedicels 4-5mm.
And since the plants are flowering at the moment, I can say Late-April is more correct than June.
Considering the above information, I would like to think that the plants here (and on our site) are V. canescens. Please advise.

We have Vincetoxicum canescens–  Here in Kashmir as per efloraofindia


You have this sp. also in JK !


It is V. hirundinaria with corolla glabrous inside, In V. canescens it is densely hairy inside. Both occur in Kashmir.


Corolla lobes are not clearly focused in the images, but I see some hairs.
It may be Vincetoxicum canescens.
May I request you to pl. post a clear image showing the corolla lobes and an image showing its calyx.


Going through the images in efi site I still fill this should be Vincetoxicum hirundinaria Medik. !


Can not say until we see a clear image showing the corolla lobes and an image showing its calyx.

Hairs are missing inside the corolla tube.

Both are reported from Kashmir
V. hirundinaria: Corolla lobes glabrous within
We see hairy here, which should be V. glaucum (Wall.) Rech.f. Flora of Pakistan treats it as synonym of V. canescens which according to POWO is a distinct species Native to East Aegean Is., Lebanon-Syria, Turkey
V. glaucum according to POWO has distribution in  Afghanistan, China South-Central, East Himalaya, Iran, Nepal, Pakistan, Tibet, West Himalaya.

Yes …, I saw your paper just now, which supports my conclusion of the above plant being V. glaucum, as according to the above paper and POWO V. canescens does not occur in our area.


Pl. check the floral images at page 57 of the publication.


The paper cites my specimen from Harwan Kashmir (my Ph.D. research area) G. Singh 833 under V. kenouriense.


So you agree for V. kenouriense?

Inflorescences mostly sessile, rarely both sessile and short-pedunculate inflorescences present on the same plant, peduncles up to 1.5 cm; bracts linear, up to 2 mm long, pubescent; pedicels 2–8 (–10) mm long, pubescent all around, sometimes pubescent along one or two longitudinal lines. Flowers yellowish-green to green, 4–5 × 2–2.5 mm; sepals tapering to acute or narrowly acute apices, up to 2 mm long, margins sparsely ciliate, calycine colleters 5 or 10 per flower; corolla tube ca. 1 mm long, lobes oblong with obtuse apices, 3–3.5 × 1–2 mm, glabrous within or sparse caducous trichomes present; corona lobes long-triangular with acute apex, slightly divergent, ca. 1 × 0.8 mm, exceeding slightly the length of the gynostegium. Follicles fusiform, up to 7 × 1 cm, apex long-acuminate, surface glabrous, slightly striate. Seeds brown, 6–7 × 3–3.5 mm, wings less than 1 mm broad; coma 2–3 mm long.

Endemic to eastern Himalayas including India and
Nepal and occurring at an elevation of over 2000 m.
 Herbarium label on W. Dudgeon & L.A. Kenoyer 56 (MO) indicates its habitat to be open grassy places.
Endemic to a long geographic range in the Hindukush Himalayas from Bhutan in the east to Pakistan in the west. The western limit of this spe-
cies is district Swat (Khyber Pakhtunkhwa province), Pakistan. It occurs on higher elevations between 1500 and 3000 m. The habitats of the species are commonly the Himalayan moist temperate forests (evergreen forests of conifers between 1500 to 3000 m elevations), rarely subalpine or open alpine lands (above 3000 m). We collected it from
open stony alpine slopes and stream side slopes in a V-shaped mountain valley. The as-ociated vegetation was either alpine herbs or conifers, and herbaceous to shrubby flora.

In view, I feel it is Vincetoxicum kenouriense (Wight) Wight only.
I have found Vincetoxicum glaucum (Wall. ex Wight) Rech. f. also in our observations, the post of which I will send to you, along with to others.


I checked all our observations.
They all appear to be Vincetoxicum kenouriense (Wight) Wight only.

Vincetoxicum arnottianum (Wight) Wight ??  Please post open flower images.


Unfortunately I don’t have flower images.


I mean to say capture when it flower.


Thank u sir. I think it is differed from Vincetoxicum arnottianum.


Tylophora is more likely. What are the species reported from the area?


What are the species reported from the area?


Sir following Sp. reported from H.P:-
Tylophora tenerrima from Shoja area of Kullu as per  Flora of Kullu by Dayal Singh Dhaliwal and M sharma 1999.
T. govanii, T. hirsuta, T. tenerrima is reported from H.P as per Flora of HP by Chowdhery and Wadhwa 1984.
What about Vincetoxicum hirundinaria??? Reported from the same location where current plant was clicked.

On checking all these species, Vincetoxicum canescens is possible.
May I request you to pl. show the close up of the flower buds?

Vincetoxicum canescens (Willd.) Decne. or some susp.??

I think this should be Vincetoxicum hirundinaria Medik. of Checklist of Nepal as per keys in Flora of Pakistan as Corolla lobes glabrous within.


POWO and Flora of Pakistan give its distribution in Nepal.

I feel there are some difference between this one sp: SK 2636 26 June 2020 and  others:
Vincetoxicum canescens (Willd.) Decne., SK 2641 29 June 2020,
SK 2246 26 October 2019
SK1981 07 June 2019 where leaves of the first one are thin and soft whereas it is hard and stiff on other sp, and looks to have some differences in flowers as well


There are a lot of variations, pl. see

These are what we have input. I am not sure !

Vincetoxicom:
Please have a look at these links of Vincetoxicum. There are two  sp. having distinct characters.

Type A : Erect, stiff, thick and linear leaf, thick fruit, hairy corolla center.
Type B: Not stiff, thin and soft leaf, thin fruit, glabrous corolla center.

I am aware about these and tried quite hard, but unable to get any lead other than these belonging to the same species.
