Yes …, i think you got the correct id. We collected this species from Khurda / Khordha district in Orissa and got it identified by using Flora of Orissa by Saxena & Brahmam.
It seems that the plant is rarely distributed in Orissa (http://
You are right, … It is an uncommon species and interestingly Pachystylidium is a monotypic genus. Did you check the recent revision of the family? and what is the distribution status in India? As per the first link provided by you, it is seemingly reported from OR, MP, CG, BI only. Is your collection a new distributional record to NE India?
And i could not find any picture of this species in the net, except now in efloraofindia database. So perhaps u r first to share pictures to the world. Congrats!
Attaching mine (not a good pic though).
I think the identification is correct. However, Pachystylidium hirsutum has not been recorded from Eastern Himalayas. So far it is known from Odisha, Andhra Pradesh and Madhya Pradesh. Hence it may be a new record for Arunachal Pradesh. But survey of literature is needed to find out if anybody recorded it from Arunachal Pradesh. If … can locate the plant again in its natural habitat, he may kindly prepare herbarium specimens and donate to BSI herbaria at Itanagar, Shillong and Central National Herbarium at Howrah, it would be very useful.
I am extremely sorry. It is Megistostigma burmanicum, a new record for Arunachal Pradesh.
Distribution known so far: India (Nagaland), Myanmar, China, Thailand and Malaysia
