25. Microchirita tetsanae C.Puglisi, sp. nov. 
Species characterised by the presence of a dimorphic indumentum on the anthers and 
sparse hairs on the filaments, and by a little projection at the anther insertion. It is 
most similar to Microchirita thailandica C.Puglisi, but differs in the upper lobes not 
being imbricate with the lower, and in the filament projection. - TYPE: Thailand,

cordate, apex acute to acuminate, finely pubescent above and beneath, ciliate along the 
margin, margin entire or sparsely and minutely denticulate, 6-17 pairs of secondary 
veins, venation slightly sunken above and raised beneath in fresh material, flat in dry 
specimens, tertiary venation inconspicuous. Inflorescences cristate, 1-5-flowered; 
peduncles reduced or 3-8 mm long, fused with each another, pubescent; bracts absent;

base, tube 0.3-0.5 mm long, lobes imbricate, narrowly lanceolate, 4.5-8 x 1-1.2 mm, 
apex acuminate and thickened, margin entire, outer indumentum of long eglandular 
hairs along the midrib, margin eglandular ciliate, inner indumentum of eglandular 
hairs at the tip and sparse sessile glands. Corolla 17-26 mm, tube white to pale blue, 
lobes white or purple-blue, the base of the upper lobes white or dark blue, lower 
lip pale blue or white at the base, with a bright yellow stripe ventrally, tube narrow, 
strongly curved, lower lip expanded, upper lip slightly reflexed, glabrous at the base, 
then finely eglandular hairy, the base of the upper lobes and of the ventral lobe with a 
dense glandular indumentum, the lobes sparsely glandular hairy; tube 10-13 mm long 
dorsally, 13-20 mm ventrally, 10-14.5 mm laterally between lips; upper lobes elliptic, 
2-6 x 2-7 mm, lateral lobes obtuse, 4-6 x 5-8.5 mm, ventral lobe elliptic, 4.5-7.5 x 
6-12 mm. Stamens arising 6-10.5 mm above the corolla base; filaments straight, with 
a little projection dorsally at the base of the anther, pale yellow, sparsely and minutely 
hairy, 2.5-3 mm long, 0.4-0.6 mm wide; anthers white, with an indumentum of long 
coloured hairs growing on the outer end and short white hairs growing on the inner end, 
1.7-2.5 x 1.5 mm, apically joined by a connective, thecae parallel; lateral staminodes 
0.7-1 mm long, arising c. 1.5-7 mm above the corolla base, central staminode 0.2-0.5 
mm long, arising 3-7.5 mm above the corolla base. Disk annular, margin subentire,
