Hooghly – might be Vandellia hirsuta Benth, : Attachments (6). 4 posts by 3 authors.

This is from Serampore (recorded today- 26.8.13), Hooghly, Flowers are as small as my previous upload, but the plant is not as succulent and seems to be slightly hairy.


Is it not same as in your other post: Hooghly – Vandellia multiflora G. Don ? (Identified as Lindernia viscosa (Hornem.) Merr.)


I fail to understand how a glabrous plant, and with different sepal-to-capsule ratio can be grouped into a single taxon, viscosa.

I think, besides glabrous, other salient differences are 1) leaf margin [crenate/sinuate vs. serrate] 2) in this plant orbicular capsule is smaller than sepals (a 2in1 plate + key attached).
Less important point, as i have observed, this plant is rather less succulent (it might be due to less humid soil).

Possibly Lindernia mollis

Looks close. Col has shown distribution in Assam, so it may be possible !


This one is reported from Kurung Kumey district, Arunachal Pradesh already.


It may be correct !


I took this species to the notice of  P. Sunojkumar, as he have worked in Lindernia of India.

His comments were: 
It is Lindernia viscosa (Hornem.) Merr. (=Lindernia hirsuta). 
This species shows high variation in its leaf shape and hair pattern (glabrous to densely hirsute). But there is no considerable variation seen in the floral characters.

Lindernia mollis / Vandellia montana ? : 10 posts by 4 authors. Attachments (5) – 1 mb each.

This sample was collected Sept 14 2020 in Dhaka, Bangladesh. Definitely in the Linderniaceae family, distinctive for the large leaves (3-4cm) and relative small flower (~4mm). Appreciate your input

Looks different.


Can it be Lindernia diffusa? I have found the same plant and was never sure about its identity.


Thanks, … But looks different from Lindernia diffusa as per
Research Gate

I think this is Lindernia viscosa (a highly variable species) as per images and details herein and as per comparative images at Lindernia


Since I posted these photos I had been wondering whether it is Lindernia multiflora (Roxb.) Mukerjee. It’s very similar to this specimen.  However, all other confirmed L. viscosa photos I see have the corolla’s lower lip at right angles to the upper lip (as in other L. viscosa samples I’ve seen near here), but in the area I’ve collected these samples none of them have this characteristic. Since this characteristic is not in the descriptions, I guess it isn’t essential. Thanks for your identification, I trust your judgment. 


Leaf shape is different in your link at this specimen


Thank you …, I had puzzled over this plant for some time. You must be correct
