corolla lobes

Corolla lobes almost free to base, united in pairs at base, or united into a very short tube up to 1 mm.

Stems and leaves sparsely hairy when young, glabrescent; corolla lobes glabrous, contrasting sharply with prominently hairy throat.

Corolla lobes yellowish; labellum white with yellowish margin, narrowly elliptic.

Labellum reflexed, adnate to filament to form a slender tube above lateral staminodes and corolla lobes.

Lateral staminodes petaloid, larger than corolla lobes.

Nectaries on corolla lobes; stigma elevated above ovary, not decurrent.

Corolla lobes oblong to ovate, ca. 2 mm, reflexed, glabrous except for densely glandular granulose margin, apex obtuse.

Stem leaf blade bases obtuse to rounded, subamplexicaul; corolla lobes shorter than tube, suberect.

staminodes 5, subulate to triangular, inserted in throat and alternating with corolla lobes.

staminodes petal-like, alternate to corolla lobes.

lobes ovate-lanceolate, 2-3 mm. Stamens exceeding corolla lobes or not.

staminodes 5, linear to ligulate, alternating with corolla lobes.

4 (3) Corolla lobes densely long pilose inside, without a longitudinal fold .

Stamens 5; corolla lobes denticulate; calyx not scaly outside.

Corolla white; lobes navicular, ca. 2 mm. Stamens ca. equal to corolla lobes.

Calyx 4-parted, lobes subequal; corolla lobes dark blue when dry.

Corolla lobes 5-7 mm, broadly lanceolate, corolla widening above base of lobes.

Corolla lobes to 2. 5 cm; calyx as long as or slightly shorter than corolla.

Sepal 5, corolla lobes 5, partial combine.

Bracts ca. 1. 5 cm; corolla lobes, lateral staminodes, and labellum to 1. 5 cm.

2 (1) Stigma small, ca. 2 mm in diam. ; corolla lobes 7, entire.

Labellum white, oblong-cuneate, shorter than corolla lobes, margin recurved, crisped;

Stamens inserted at same or different levels on corolla at base, alternate with corolla lobes, exserted to included;

Central lobe of labellum with purple stripe and cream blotches, oblong-obovate, shorter than corolla lobes;

Stamens inserted at 1 side of base of each corolla lobe, alternating with corolla lobes;

Stamens inserted at throat of corolla tube just below sinus between corolla lobes;

posterior pair perfect, inserted at base of corolla lobes, included;

Female flowers: corolla lobes linear-oblong;

Stamens as many as corolla lobes and alternate with them, inserted within corolla, all alike or 1 or more reduced;

Stamens included; filaments adnate to lower part of corolla lobes, free parts ca. 2 mm;

Stamens 5, inserted at corolla base, alternate with corolla lobes;

Stamens ca. as long as to slightly shorter than corolla lobes;

Stamens included; filaments adnate nearly to middle of corolla lobes, free parts ca. 0. 5 mm;

stamens 10, unequal, long ones half as long as corolla lobes;

Stamens 10, included: 5 basal or hypogynous, 5 inserted high on corolla and alternating with corolla lobes;

filaments adnate to base of corolla lobes, free parts 3--4 mm;

Stamens 5[or 10], epipetalous, alternate with corolla lobes if 5;
