The distribution extends to Myanmar and Thailand.

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.
