12. BOUCHETIA DC. 
Low and much branched from a perennial root, with entire leaves, 
oblong, campanulate 5-cleft calyx with narrow lobes, short funnelform 
corolla, 5 perfect but unequal stamens, connivent anthers with cells

13. LEPTOGLOSSIS Benth. 
Low perennial diffusely much branched from a woody base, with 
5-cleft or toothed calyx, salverform corolla with slender tube and swol-

stamens (the fifth a sterile filament), somewhat reniform anthers con- 
fluent at summit, stigma or style under it petaloid-dilated, and 2-valved 
pod. 
1, L. TexanaGray. Viscid-pubescent: leaves spatulate-obovate or oblong, acute,
