A revision of Microchirita in Thailand 
233 
Wood (1974) listed a number of synonyms for Chirita hamosa, all from India. 
As noted by Middleton & Triboun (2013), several different species were included in 
Wood’s concept of Chirita hamosa so we refrain from listing any of these synonyms 
pending a thorough revision of the genus in India.

towards the apex, apex acute, outside sparsely eglandular hairy at base, hairier distally, 
inside with an indumentum of sparse sessile glands. Corolla 10-15 mm long, narrow 
basal portion greenish white, rest of tube white, with a yellow stripe ventrally inside, 
lobes pale lilac, tube with a narrow basal portion, then broadening into a funnel-shaped 
distal portion, this curved down, pubescent outside except at base, inside glabrous, 
the upper lobes densely covered in stalked glands, the lower central lobe sparsely so, 
the lower lateral lobes glabrous; tube 9-12 mm long dorsally, 10-11 mm ventrally, 
8.5-9 mm laterally between lips, upper lobes broadly elliptic, 2.5-3 x 4^1.7 mm, 
lower lateral lobes elliptic, 2-4 x 4-5 mm, lower central lobe rounded, 3-4 x 4-5 mm. 
Stamens arising 4-6.5 mm above the corolla base, filaments glabrous, 3-3.5 mm
