Hygrophila difformis is known from India, Mayanmar, Bangladesh and Nepal. In India it is reported from Kerala, Uttar Pradesh and West Bengal (Cook 1996). I think there is now reasonable evidence that the attached photos are of Hygrophila triflora (Roxb.) Fosberg & Sachet. This plant was photographed on 19-Dec-2012 at another place in Hooghly.
It is very possible that my earlier uploads at and at are same species. On checking the links provided by you it seems to me that the earlier uploads (species) reported by you are not the same compared to the present ones. On checking the links provided by you it seems to me that the earlier uploads (species) reported by you are not the same compared to the present ones. I also agree with you, the plant in this thread looks different than the earlier two posts. I try to explain :-
If we stress on the “Aroma” and other characters, as explained in my “decussate herb from Hooghly”, the plant in that post is most likely Hygrophila triflora (Roxb.) Fosberg & Sachet.
If you agree that the plant in this post is replica to the species at biolib.cz then this plant is Hygrophila triflora (Roxb.) Fosberg & Sachet. But the fact that it is not (if yes, very mildly) aromatic goes against the description of “Bengal Plants”.
My third species is without flowers, submerged in water and thereby it was simply a speculation, based on place, occurrence, habitat, and other morphological similarities.
However, all the three species (or is it one?) are adapted to aquatic habitat, have variable leaves (according to habitat), decussate and hairy; the two of them have similar flowers. The aroma is a point, but i have seen variation in smell in Telosma pallida. please move all my threads under Hygrophila difformis (L. f.) Blume to Hygrophila triflora (Roxb. ex Nees) Fosberg & Sachet. BSI will tell you that H. difformis (L.f.) blume is restricted to E Himalaya. decussate herb from Hooghly 2-12-12 sk: But these pictures are recorded in unused fields very near the very ditch where i recorded the pictures in the above link.
Two species at The Plant List :-
Species : Hygrophila triflora (Roxb.) Fosberg & Sachet ?
H & H : small herb, erect, sometimes decumbent; avg. 1 ft high
Date : 02/12/12, 11.50 a.m.
Place : Hooghly There is a post by … at – efi thread. Suggested id(s) are 1) Hygrophila heinei, 2) Species of Justicia Some links (for the above post) : –
The post above might help ID the plant in this thread.
Description of Cardanthera in Bengal Plants and in FBI can be found.
According to The Plant List, Ruellia triflora Roxb. might be the Hygrophila triflora (Roxb.) Fosberg & Sachet.
Attaching more pictures, recorded yesterday.
This plant is Hygrophila triflora (Roxb.) Fosberg & Sachet, i think. The day before yesterday i downloaded Flora Indica and found this plant may not be Ruellia triflora Roxb. copying a few points from F. I. iii. 52. –
R. triflora R.
Found more links that suggest the ID of this plant is Hygrophila triflora (Roxb.) Fosberg & Sachet., though i think this doesn’t fully satisfy Ruellia triflora Roxb. The links are :
please move all my threads under Hygrophila difformis (L. f.) Blume to Hygrophila triflora (Roxb. ex Nees) Fosberg & Sachet. BSI will tell you that H. difformis (L.f.) blume is restricted to E Himalaya. , (… 1981), we proposed the new combination Hygrophila triflora (Roxburgh) Fosberg & Sachet, based on Rue Ilia triflora Roxburgh, Hort. Beng. 46, 1814. We did this in spite of Heine’s having placed this basionym in synonymy under Hygrophila …)
(H. difformis is a beautiful plant from India, Burma, Thailand, and the Malay Peninsula. It was first described by Linnaeus himself in 1781 as Rueliia difformis. It’s also been called Rueliia triflora, Synnema triflorum, and Hygrophila triflora …) underwater garden from Hooghly 24-11-12 sk1: Species : UNKNOWN
H & H : aquatic herb, maybe 2 feet high
Date : 22/11/12, 11.58 a.m.
Place : Hooghly Found something similar :-
Please ignore my earlier comment, this species can be anything, including Rotala & Hygrophila. I imagine if this is some Limnophila sp. I think this is Hygrophila triflora (Roxb.) Fosberg & Sachet, as in another post at – efi thread. For the very same reason as in efi thread, this plant also may not be Hygrophila triflora (Roxb.) Fosberg & Sachet. KEW herbarium will tell you this is also Hygrophila triflora (Roxb. ex Nees) Fosberg & sachet. . Hygrophila species: I have collected the acanthaceae member (may be Hygrophilla) will you please help me to identify it. i found one post on eflora india group Hygrophila Kunnur kerala. ID GK191216- 1 my specimen is exactly look like it.
My specimen shows five stamens in flowers. bilabiate corolla hairy outside, bluish white in colour.
Location Sindhudurg District, Maharashtra Hygrophila erecta (Burm.fil.) Hochr. ??? I checked all the species listed at Hygrophila.
I think it looks somewhat close to specimens (one and two) of Hygrophila triflora at GBIF.
I think it looks different from the images of Hygrophila erecta in GBIF.
The herb seems to be Hygrophila species, Petal character is wanting It appears to be Hygrophila triflora as per discussions at Hygrophila species
