Common deciduous trees in inland forests, up to 5 m high on clayey loam. The inflorescences arise precociously and the fruits are almost ripe when the young leaves are still unfolding.
The distribution extends to Myanmar and Thailand.

From Andaman Islands.
pictures with great clarity and i take it that these are the salient diagnostic features in two photos? please can you tell me/us more? thank you …
Kindly go through Flora of India vol. 23 available online in BSI cloud portal and many details are there about Croton oil and other uses as well as characters, habit, habitat and distribution.

its an abstract. of article
quote: A shoot tip culture procedure has been developed for the rapid multiplication of Croton sublyratus Kurz, a tropical plant species cultivated in Thailand for the production of an anti-ulcer medicine, plaunotol. Optimum conditions were established: (1) for the regeneration of shoots from shoot tips: (2) for axillary shoot formation and rooting and (3) for adaptation of regenerated plants to the open ground. The results demonstrate the feasibility of applying the shoot tip culture technique for enhancing production of plaunotol by cultivating uniform populations of C. sublyratus with higher plaunotol levels. end quote from url: https://link.springer.com/article/10.1007/s002990050195
Yes, in Thailand this is not C. sublyratus but C. stellatopilosus, which was so far misidentified as sublyratus. These two species are very close to each other differing only in the nature of the foliar glands. Croton sublyratus occurs in Andamans and Myanmar and it’s properties should be same as C. stellatopilosus of Thailand and Myanmar. The characteristic feature is that they are flowering precociously and the fruits are almost ripe when the young leaves are still unfolding.
Croton oil is obtained from the seeds of C. tiglium, an ancient plant of medicine. However, it is now excluded from different pharmacopoeia due to its drastic purgative nature.
