For Identification_02012011_DS_SN2: Snapshot of another climber - shot taken today in Uluberia garden, Howrah, West Bengal. is it a kind of ipomoea? Flowers tiny, approx. .5 inch dia. 

Need ID for a flower.:  I tagged my photo for a flower as  Evolvulus alsinoides ( dwarfed Morning glory  or शंखपुष्पी) but got confused when someone said it could be Jacquemontia violacea.
Can you help me to confirm the identification of flower in my photo and provide some more inputs on Jacquemontia violacea flower to understand the difference?
The URL for my photo is

E. alsinoides is a tiny wild herb spreading on ground and the flowers are solitary and just 5-7 mm. Jacquemontia violacea is a large twining climber found in gardens, the flowers are in clusters and about 2 cm dia. It looks to be Jacquemontia but you are best placed to differenciate depending on the size and where you clicked them.
yes it is Jacquemontia (twining climber) and not Evolvulus (small prostrate herb)
Native to tropical America, it has spread to many tropical countries because of the ease with which it can be grown and for its beautiful appearance. Ideal for covering trellises and growing in pots over "balloons," Skyblue Clustervine is a small freely blooming creeper of controllable growth.  
The stem of the creeper is slender and green and the leaves are arranged alternatively.
The leaves are small, shiny and heart-shaped with pointed tips.
The bell-shaped white-throated ultramarine blue flowers are produced in clusters at the ends for long stalks. The creeper looks gorgeous with its many flowers spread on it after rains and in the cooler season.  
Compared to other members of morning glory family, the flowers are smaller. They are about the size of a one-rupee coin or 2.5 cms across, with the petals fixing into bell shape with five stamens.

..., this I suppose is J. coerulea, a cultivated climber with 2 cm blue flowers. J. paniculata is a wild plant with 1 cm white flowers.
... please validate if Jacquemontia violacea (Vahl) Choisy is also a possibility.
Changed to Jacquemontia paniculata (Burm. f.) Hallier f. only on finding that J. violacea is put as its synonym at The Plants List.
To me your plant seems to be the same as one uploaded by ... as Jacquemontia pentantha, and also commonly cultivated in Delhi. J. paniculata and J. coerulea seem to be quite distinct species. J paniculata has calyx lobes ovate-lanceolate nearly 5-6 mm broad, and corolla shorter barely 1 cm long as against 2-4 mm broad and corolla 2 cm long in J. pentantha. Plus if we see most photographs on net including one on Flowers of India (...), J. paniculata has lighter coloured (nearly white flowers with distinctly narrow and sharply pointed corolla lobes.
Jacquemontia coerulea (Schum. & Thonn.) Choisy ex G. Don is now considered as synonym of J. ovalifolia (Choisy) Hallier.f. seems also to have similar coloured flowers but with much broader corolla lobes and apparantly larger flowers and much different oval leaves..
But there also seems to be confusion about the status of Jacquemontia violacea. Flora of China reports Fang and Huang (Fl. Reipubl. Popularis Sin. 64(1): 46. 1979) incorrectly listed Jacquemontia violacea (Vahl) Choisy, based on Convolvulus violaceus Vahl, as a synonym for J. paniculata. Jacquemontia violacea is a synonym of J. pentantha (Jacquin) G. Don, a West Indian species introduced to Asia as an ornamental but not known to be in China.
The Plant list only adds to the confusion. It treats it as synonym of Jacquemontia paniculata (Burm. f.) Hallier f., but treats its basionym Convolvulus violaceus Vahl as synonym of Jacquemontia pentantha (Jacq.) G. Don
My thoughts after going through each name, ... my posted plant looks fitting to J. violacea, now a synonym of J. pentantha, update from ... search.

I agree on the latest legitimate name of Jacquemontia pentanthos 

Convolvulaceae Week: Jacquemontia pentantha from Delhi:  

Jacquemontia pentantha (Jacq.) G. Don

Climber with ovate-cordate leaves, flowers blue about 25 mm across on long pedunculate cymes.

Closely similar to J paniculata which has calyx lobes ovate-lanceolate nearly 5-6 mm broad, and corolla shorter barely 1 cm long as against 2-4 mm broad and corolla 2 cm long in J. pentantha.

Photographed from Delhi

The plant matches what I know about Jacquemontia pentanthos.
The closeup showing the structure of the stigma is nice .

Jacquemontia sp. For ID


Most probably a planted one.

J pentantha may be
I agree although I prefer to use the epithet spelling J.pentanthos
