 strongly plicate-ridged, its teeth acute, the lower much shorter, the lowest pair upcurved to 90 

 toward the uppermost lobe, which is upcurved-projecting; corolla 25^0 mm. long, yellovv, its 

 throat ventrally deeper yellow and with carmine spots and sometimes a median blotch, with 2 

 strongly developed and densely hairy ridges that join distally to form a palate that closes orifice,

 yellow ridges, its lobes spreading, nearly alike, retuse to shallowly notched, magenta at base (so 

 forming a dark purple ring around the open orifice) ; anthers glabrous ; stigmas very unequal, 

 the upper rudimentary, the lower recurved and effecting self-pollination by the eventual adherence 

 of the anthers ; capsule 5-6 mm. long, dehiscing slightly through septum-apex.
