2. Leaves not reddish, less than ½ as broad as long; wild plant of moist or aquatic habitats. ….. 2. A.philoxeroides.
1. Inflorescence a sessile head in leaf axils
3. Plants prostrate, mat-forming
4. Leaves atleast ¾ as broad as long, stems and leaves rigid; flowers (tepals) spine-tipped …… 3. A. pungens
4. Leaves usually less than ½ as broad as long, stems and leaves soft; flowers (tepals) not spin-tipped … 4. A. paronychoides
3. Plants erect or spreading not mat-forming
5. Leaves sessile, linear or narrowly oblanceolate; plant of moist or wet situations …… 5. A. sessilis
5. Leaves with distinct petiole; mostly cultivated
6. Leaves green or tinged with purple; mostly oblanceolate, gradually narrowed into petiole, less than ½ as broad as long ….6. A. bettzickiana (incl. A. amoena and A. versicolor)

I have updated eFI (efloraofindia) page on Alternanthera
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 the list of Indian species based on Karthikeyan et al. (2009).
Thanks, … Species at other links seems to match with it.
