y\-| by J-Y6 i^-' *^i® terminal leaflet a little larger than the lateral ones, 

 all acute and mucronate at the apex, glabrous above, silky-pubescent, 

 strongly nerved and gland-dotted beneath, base subacute or rounded ; 

 lateral leaflets subsessile, the terminal with a petiolule about j^ in. long. 

 Elowers small, 1 or few, sessile in the axils of leaf-like stipulate bracts 

 and forming close terminal heads or spikes. Calyx -^ in. long, mem-
