This species was described in 1857; it is known only from material that was collected in 1828 somewhere in the Sylhet Division in north-eastern Bangladesh.
The original locality is now a very densely populated region and given the fact that the species has never been relocated since its description, it is quite safe to say that it is extinct.

Kress’s Chlorospatha (Chlorospatha kressii)
Kress’s Chlorospatha was described in 1991, it is known only from the type locality, a small enclave of relatively intact, lowland primary forest southeast of the town of Quibdó in the Chocó Department of Colombia, where the plants grew on slopes near a stream in deep primary forest. [1]
The species was collected in 1986, at a time when extensive logging began in the region; the type locality is now apparently completely deforested and this species seems to be extinct.
