with the upper lip undivided (jig. 484) or bifid (fig. 485), and 
commonly more or less arched over the lower lip (jig. 484), or 
sometimes nearly suppressed (fig. 1024); the lower lip 3-lobed 
(fig. 1024), with the odd lobe anterior (fig. 1023); or rarely the 
corolla is nearly regular. Stamens usually 4, and then com- 
monly didynamous (jigs. 487, 1025, and 1026), or very rarely of 
nearly equal length, or only two by abortion ; anthers 2-celled, 
or 1-celled by abortion ; the filament or connective sometimes 
forked, each branch then bearing a perfect cell, or the cell on 
one side obsolete or sterile (fig. 1028). Ovary (figs. 609 and
