 inch long besides the slender petiole) : inflorescence spiciform and interrupted ; clusters sev- 

 eral-flowered : pedL-els short (a line long) : floral leaves abruptly reduced to membranaceous

 small ovate and slender-acuminate very caducous bracts : inflorescence racemose-spiciform, 

 of numerous and several-flowered distant clusters : pedicels as long as the tube of the 

 oblong-campanulate calyx; the broad lips of which are divergent and half the length of 

 the tube, the upper mucronatcly (often minutely) 3-toothed, lower 2-cleft, its teeth broadly
