and the separated placentae of Diplacus. The capsule is short 
and broad and apparently does not split the calyx when mature. 
Тһе spiral twisting of the upper part of the calyx over the mature 
capsule is unlike that of any other species in the genus. Тһе 
type sheet contains only two short branches of this unusual plant, 
and as this is the only material known it has been impossible to 
tell anything about the size of the plant nor can the color of the 
flowers be determined.

Shrubs 6-18 dm. high; leaves thick, firm, usually dark green, 
mostly revolute in the bud and with compound sessile glands on 
one or both surfaces; calyx narrow-prismatic or tubular, generally 
closely adhering to the capsule and ruptured by it in dehiscence, 
throat oblique, teeth short, unequal; corolla funnelform, yellow, 
orange, red, or salmon color, mostly distinctly bilabiate WI 
wide open throat and more or less spreading irregular lobes; 
stamens glabrous, approximate in pairs, unequally inserted, ut 
longer pair inflated at the point of attachment, anthers co ven 
at apex, glabrous; style glandular-pubescent along the uppe 
half, often thickened at the base when mature; stigma-lips ed 
or subequal; capsule linear-oblong, firm, coriaceous, commonly 
dehiscent down the inner suture and held open along the жс 
one, occasionally dehiscent down both sutures, the broad p 
centae borne on the valves. Sp. 107-114.
