Florae Indicae Enumeratio: Monocotyledonae, written by S.Karthikeyan, S.K.Jain, M.P.Nayar & M.Sanjappa, and published by Botanical Survey of India is an important reference for names and distribution of Amarylidaceae species in India. As per this document (Karthikeyan et al. 1989) following species of Crinum occur in India:
  1. Crinum amoenum Roxb. ex Ker-Gawl.
  2. C. asiaticum L. [var. asiaticum; var. procera]
  3. C. brachynema Herb.
  4. C. defixum Ker-Gawl. [synonym of Crinum viviparum (Lam.) R.Ansari & V.J.Nair]
  5. C. eleonorae Blatt. & McCann [forma- eleonorae; forma- pupurea]
  6. C. humile Herb.
  7. C. latifolium L. [var. latifolium; var. zeylanica,]
  8. C. pratense Herb. [synonym of Crinum lorifolium Roxb.]
  9. C. pusillum Herb.
  10. C. stracheyi Baker
  11. C. wattii Baker
  12. C. woodrowii Baker

Scrutiny of names in The Plant List indicate some as synonym as mentioned against these names. One variety C.latifolium var. zeylanica is now known as a distinct species-

    13. Crinum zeyanicum (L.) L.

In addition to these two new species of Crinum are described recently-

    14. C. malabaricum M.M.Lekhak & S.R.Yadav

    15. C. solapurense S.P.Gaikwad, K.U.Garad & R.D.Gore

I have updated eFI (efloraofindia) page on Crinum

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.

Thank you for updating a new species in database (eFlora of India).
I have added list of species known in India based on a BSI reference, Plant List and two new publications as given on this page.
Thanks, ... Species at other links match with this.

Pl. go through Crinum page (Amaryllidaceae) with images of species in efloraofindia (done by Bhagyashri Ranade ji).

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.
