Notes. This species is recognisable by the small, white flower with a tubular corolla, 
and by the relatively short and densely hairy fruit. It is widespread across the north 
of Thailand and in the neighbouring countries. It frequently flowers when only a 
unifoliate plant. 
Microchirita hamosa is conserved with a conserved type (proposed by 
Middleton & Puglisi, 2015; supported by Nomenclature Committee for Vascular 
Plants in Applequist, 2016).
