FLOWERING PLANTS OF INDIA, DICOTYLEDONS, Vol-I (Acanthaceae-Avicenniaceae) authored by S. Karthikeyan, M. Sanjappa and S. Moorthy and published by BSI, Kolkata in 2009 is an important document for names, authority and distribution of Acanthaceae species in India.

As per this document (Karthikeyan et al., 2009) following species of Hygrophila occur in India:

  1. Hygrophila anomala (Blatt.) M.R. Almeida
  2. H. balsamica (L.f.) Raf. [var. balsamica; var. thymus]
  3. H. difformis (L.f.) Blume
  4. H. erecta (Burm.f.) Hochr.
  5. H. griffithii (T.Anderson) Sreem.
  6. H. heinei Sreem. [var. heinei; var. birbhumensis (B.P. Guha) H.B. Naithani & S. Biswas
  7. H. incana Nees
  8. H. madurensis (N.P. Balakr. & Subr.) Karthik. & Moorthy
  9. H. phlomoides Nees [var. phlomoides; var. roxburghii]
  10. H. pinnatifida (Dalzell) Sreem.
  11. H. polysperma (Roxb.) T. Anderson
  12. H. pusilla Blume
  13. H. ringens (L.) R. Br. ex Steud. [var. ringens; var. assurgens; var. cochinensis]
  14. H. schullii (Buch.-Ham.) M.R. Almeida & S.M. Almeida [synonym of H. auriculata (Schumach.) Heine]
  15. H. serpyllum (Nees) T. Anderson [var. serpyllum; var.  hookeriana]

I have updated eFI (efloraofindia) page on Hygrophila

Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links.

Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details.

If someone can provide complete list of Indian species with source references it will be wonderful.

Any comments/ corrections are welcome.


I have added list of species of Hygrophila in India based on Karthikeyan et al. (2009).


Thanks a lot, …, Species at other links matches with it.

Pl. go through Hygrophila page with images of species (done by me) in efloraofindia.

If you find any mis-identification, pl. let us know. If anybody can send images of other species of this genera (for incorporation in the website), it will be really nice.
Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let us know.
