Pecharthal Tripura
Kindly identify

Any idea about the family ?

Haven’t come across this plant, but two families where they are common are Orobanchaceae and Orchidaceae.. kindly chk them..

I think this is Cyrtosia javanica [Orchidaceae]

The photos are not clear. Hope it may be a member of Orobranchaceae

Thanks, … Identified as Cyrtosia species of Orchidaceae.

Very interesting. I saw a brother of this live in Laos in 2012, so happy to see this, although just the image.

This is either Cyrtosia nana or Cyrtosia javanica, both of which are known from India and are of smaller size like this.
I need to see a better pic.
If I have to guess this could be Cyrtosia nana (owing to the widely open flower that i can see in one of the image), but cant confirm.
The seeds of this are supposed to be dispersed by birds in Japan and I assume it applies in India too.

Very interesting plant.

Four sp. have got distribution in Tripura :
Cyrtosia lindleyana Hook.f. & Thomson
Cyrtosia falconeri (Hook.f.) Aver.,
Cyrtosia javanica Blume and
Cyrtosia nana (Rolfe ex Downie) Garay
And looks closest to Cyrtosia javanica Blume ! Cyrtosia lindleyana Hook.f. & Thomson , Cyrtosia falconeri (Hook.f.) Aver., Cyrtosia javanica Blume, and Cyrtosia nana (Rolfe ex Downie) Garay

Cyrtosia javanica or C. nana. Not easy to make out from these pics, both are found in north east. If I have to guess owing to faint colour of fruit i would say Cyrtosia javanica. But cant confirm.

The seed development of a mycoheterotrophic orchid, Cyrtosia javanica Blume– Yang Chih-Kai and Yung-I Lee- Yang and Lee Botanical Studies 2014, 55:44 (Abstract- Cyrtosia javanica is a rare, mycoheterotrophic vanilloid orchid native to the bamboo forest in central Taiwan. Like some vanilloid orchids, the seeds of C. javanica are hard and difficult to germinate in vitro. A better understanding of the embryology would provide insights in the propagation and conservation of this rare species. Based on the histological and histochemical studies, we observed some remarkable features in developing seeds of C. javanica. First, the developing embryos without a structurally defined suspensor; Second, the chalazal accessory cells have densely stained cytoplasms that are different from the adjacent cells of seed coat; Third, the multiple layers of seed coat with the lignified in the outermost cell layer of the outer seed coat. In C. javanica, the large and heavy seeds embedded in fresh fruits may adapt to the dispersal strategy. The hard seeds with lignified outer seed coat could provide a rigid protection during seed dispersal but also cause coat-imposed dormancy. This study provides insights in the seed coat structure and the hints of seed treatment methods.)
