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 Asclepiadaceae

As per this document (Karthikeyan et al., 2009) following species of Decalepia occur in India:
1. Decalepis araylpathra (J.Joseph & V. Chandras.) Venter
2. D. hamiltonii Wight & Arn.
3. D. nervosa (Wight & Arn.) Venter 

Scrutiny of these names in The Plant List indicate them as accepted names. In addition to these one another species D. salicifolia (Bedd. ex

Pollination Biology of Decalepis Hamiltonii and Shorea Tumbuggaia by Aluri Jacob Solomon Raju- Lambert Academic Publishing, 2010 – 64 pages-
In Decalepis hamiltonii, extended flowering pattern, self-incompatibility, pollinator limitation, absence of seed dormancy, abortion of a considerable percentage of seedlings prior to establishment are contributing factors for the regulation of its population size. Further, the roots of this plant are over-exploited due to its commercial value in the preparation of a soft drink “nannari sharbat” in India.

Decalepis salicifolia (Bedd.ex Hook.f.) Venter (Apocynaceae)-A new source for 2-hydroxy-4-methoxybenzaldehyde by Satheesh George, C.T. Sulaiman, Indira Balachandran, Anu Augustine- Medicinal plants-International Journal of Phytomedicines and Related Industries 01/2011; 3(3):259-260.
ABSTRACT : The tuberous roots of Decalepis salicifolia (Bedd. ex Hook.f.) Venter (Syn. Utleria salicifolia Bedd. ex Hook.f.), a critically endangered and endemic medicinal plant with very narrow restricted distribution, have been investigated. The volatile oil obtained after steam distillation was processed further and yielded a pure compound. The isolated compound was characterized using IR, MS, 1H NMR, 13C NMR and identified as 2-hydroxy-4-methoxybenzaldehyde. This is the first report of occurrence of this compound from this plant.

I have updated eFI (efloraofindia) page on Decalepis

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 species of Decalepis in India based on Karthikeyan et al (2009) and The Plant List.

Thanks, … Species at other links match with this.


Pl. go through Decalepis (‎‎Apocynaceae) 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), if any, 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.
