 dorsally, loosely nerved, the upper ones much smaller, about 2-3 mm. long, 

 elliptical, membranaceous. Flowers about 1-3-crowded, about 3| cm. long, 

 erect, with a short and pubescent pedicel 5-9 mm. long. Calyx loosely, 

 campanulato-tubular, unequally 3-lobed, membranaceous, finely pubescent 

 (denser below) externally, about Icm. long, laxly nerved; lobes semiorbicular- 

 ovato, obtuse or mucronato- obtuse or minutely suberose at the apex, minutely 

 subciliated, the one of them smaller. Corolla much exserted; finely pubes- 

 cent externally ; the tube equal to calyx in length, 3-4 mm. across in tbe 

 middle ; longer than the tube, 1^ cm. long, erect-patent, oblong-spathulate, 

 obtuse or acutish-obtuse at the apex, concave within, firmly and thickly 

 membranaceous but thinly membranaceous towards the margin, the posterior 

 one about 10-nerved and cucullate-navicular and with a cusp on the back 

 of the apex, the other two about 7-8-nerved. Lip longer than the 

 corolla-lobes and about 2^ cm. long, sessile, oblong-subspathulate, nearly 

 1 cm. wide at the middle, cut down to the middle into 2 oblong and 

 obtuse-tipped 2-lobules with a close sinus, glabrous, membranaceous, but 

 thicker in centre, furnished with sublunate decurrent minutely pubescent 

 longitudinal 2 lamellae at the base ; lateral lobes minute, deltoid, obtuse, 

 about 1 mm. long. Stamen lower than the lip, but exceeding the corolla- 

 lobes ; filament flattened, linear, glabrous, 9 mm. long ; anther relatively 

 large, oval, 9 mm. long, 6^ mm. broad ; the connective broad, 2-cleft 

 above into acutish-obtuse-tipped lobes, minutely puberulent ; anther-cells 

 linear, shorter than the connective, thickly walled ; rudimentary stamens 

 2, small, enclosed within the base of the corolla-tube, erect, oblong-lanceolate, 

 obtuse, compressed, glabrous, about 3^ mm. long. Style a little exceeding 

 the stamen, filiform, glabrous ; stigma shortly subiufundibuliform with a
