about 8 mm wide, blotched with yellow above the throat, the lateral lobes 
broader than the middle one. Capsule about 3 mm long, the calyx-lobes

cylindric, the upper lip erect, broad, concave, notched or bifid, the lower 
broader, spreading, 3-lobed. Stamens 4, all perfect, the 2 anterior ones 
with arched filaments which are appendaged at or near the base; anthers 
touching or cohering in pairs under the upper lip, the cells divaricate. 
Stigma 2-lamellate. Capsule septicidal, the valves separating from the 
placenta-bearing septum. (In honor of D. Vandelli, a Portuguese botanist.) 
Species about 26, chiefly in tropical Asia, about 6 in the Philippines. 
1. Capsule about as long as the calyx or shorter.
