Begonia wengeri C. E. C. Fisch.

Wenger’s Begonia (Begonia wengeri)

Wenger’s Begonia was described in 1932; it is apparently known exclusively from the type material which was collected on moist shady banks along water bodies in the undergrowth of the evergreen forests in the southern Lushai Hills in Mizoram, India.

The species was not found since and might be extinct.

Begonia brevicaulis A. DC.

Short-stemmed Begonia (Begonia brevicaulis)  

The Short-stemmed Begonia was described in 1859, it is, or maybe was, endemic to the state of Megalhaya, India, where it was found growing at elevations of about 300 m.

The plant had a bulbous root system, was completely stem-less and had heart-shaped, browdly ovate leaves.

The species is now considered likely extinct. 

***

The species should not be mistaken for Begonia brevicaulis T. C. Ku, which is a synonym of the Chinese Begonia sinobrevicaulis T. C. Ku.
