Came across this plant in a garden nursery at Vadodara.  Its from Apocynaceae family. (28-10-09)
Looks like Wrightia sp. Plant was still in its growing stage.

I think Citrus sp.

I think this is a variety of Wrightia arborea

it is
Wrightia antidysenterica
Family: Apocynaceae
Snowflake, Milky way, Winter Cherry Tree, Arctic Snow, Pudpitchaya, Sweet Indrajao, Hyamaraca
Origin: Sri Lanka
A small compact and bushy shrub that blooms non stop year-round. The plant all covered with 1″ white flowers that look like little stars from a distance. It is a perfect specimen for limited space garden or patio. Can be easily grown as a houseplant. Doesn’t require additional pruning. It is a medicinal plant in India.

The bark possesses anti-microbial and anti-infammatory properties and therefore the juice extracted from it is administered for mouth sores. The leaves are used in treating several skin disorders, psoriasis, nonspecific dermatitis etc. The bark is used as an adulterant for the well known drug, Holarrhena antidysenterica. Related species – Wrightia tinctoria.

Confusion regarding Kutaja or indrajao of Ayurveda and the actual plant: The plants are very distinct, no one ever confuses them. One without corona now correctly known as Holarrhena pubescens, commonly known as Indrajao, feverpod and perhaps the real Kutaja of Ayurveda.

The other is the Wrightia antidysenterica, the coral swirl popularly sold in nurseries under the name arcticsnow, Snowflake. A plant with distinct corona, petals distinctly obovate, also known as Meethi indrajao.
Let us also bring in the related species Wrightia tinctoria with smaller flowers, linear petals, also known as sweet indrajao
To resolve this confusion let us go to the original descriptions in Flora of British India and synonyms. The first plant is described as named by Wallich and subsequently A. deCandolle, and hence citation Wall. ex DC. in recent publications. Wrightia antidysenterica Grah cited as synonym. FBI is not sure about synonymy of Chonemorpha antidysenterica G. Don. Wrightia tinctoria is a distinct species and should not come in confusion except for names indrajao and kutaja sometimes applied. The third crucial plant is one described as Wrightia zeylonica (L.) R.Br. with Nerium antidysentericum L. and Nerium zeylanicum L.
At the time Flora of British India, synonyms were cited but basionym author was not included in the accepted name. When this practice started Chonemorpha G. Don remained unknown and combination came to be known as Holarrhena antidysenterica (L.) Wall. ex A. DC., many not bothering to know where this L. came from, even after recently it has been understood that correct name for this plant been understood as H. pubescens. Pl. see citations below:
The second website, though a very reputed one, but puts first black and white illustration correctly but coloured photograph shows Wrightia antidydenterica. The Plant List worst confused, even putting H. pubscens as unresolved name. The correct synonymy can be seen at:
The second plant very distinct though remained in confusion because people remembered L., but forgot where it came from till it was finally known that Wrightia zeylanica (L.) R. Br. be correctly known as Wrightia antidysenterica (L.) R. Br., and it is based on Nerium antidysentericum.
The unfortunate thing being that people remembered antidysenterica but never bothered to know where it came from, and got tagged wrongly to Holarrhena antidydenterica (L.) Wall. ex A. DC., instead of correct H. anitdysenterica (G. Don) Wall. ex A.DC. as synonym for H. pubescens. Perhaps also important to mention that earliest name for this species was given by Roth in 1821 as Echites antidysenterica 1821 as against Chonemorpha antidysenteria G Don, 1838, but Roth’s name can’t be taken as basionym (Roth can’t go in parenthesis) as it is a a later homonym of Echites antidysenterica (L.) Roxb. ex Fleming.

Thank you very much … for this clarity and analysis of confusing identities.
From the references I read and use, I find kutaja is Holarrhena pubescens Wall. ex G. Don (earlier literature quote Holarrhena antidysenterica Wall. Ex A. DC.).
All other plants related to qualities of kutaja have some descriptors prefixed – like sweta-kutaja, stri-kutaja, pun-kutaja &c.

Yes … The real confusion started when basionym author was included wrongly as L. (not knowing about Chonemorpha antidysenterica of G. Don). The the Wikipedia has confused the things further.


Thanks a lot Sir for a very detailed analysis and review of a confusing situation…the unfortunate thing is there are a large number of such confusions probably due to the fact that access to data have not been so easy as it is today…I hope, in times to come majority of confusions will be resolved…thanks for throwing light on the matter…
