Stem stout. Leaves 4-6 in. long and nearly as broad, pubescent or glabrate 
above ; petiole 14-3 in., slender. Cymes shortly peduncled, 3 in. diam. Corolla-tube 
fyiindrie, in. long; lobes spreading and recurved, thick. Column nearly filling the 
ube. 
ll. M. thyrsiflora, Hook. f.; nearly glabrous except the puberulous 
cymes, leaves broadly ovate or oblong- or deltoid-ovate deeply cordate acumi- 
nate, cymes elongate of clusters of shortly peduncled flowers on a long rachis, 
corolla urceolate glabrous without and within, lobes lanceolate, coronal scales 
short rounded wholly adnate to the long subulate anther-tips. M. tinctoria, in

Leaves 4-8 by 2-6 in., membranous ; petiole 1-3 in. Cymes 4-6 in. long; rachis 
flexuous ; pedicels very short. Sepals nearly glabrous, obtuse. Corolla 75-75 in. 
long ; lobes coriaceous. Anther-tips longer than the column, basal spurs very small. 
Stigma fusiform. Follicles 2 in. long, dagger-shaped, turgid below ; pericarp thinly 
coriaceous, glabrous. Seeds ovate, à-l in. long.—So similar to some forms of M. 
tinctoria in foliage and inflorescence as to be easily mistaken for that plant. The 
coronal scales may be said to be absent.
