Descr. Stem erect, straight, a foot to a foot and a half, 
or, in the wild specimens, two feet high, rounded, quite 
glabrous, but little branched. Leaves glabrous, lanceolate; 
the lower ones attenuated into petioles, the rest quite 
sessile, and almost connate, gradually smaller upwards: all 
of them quite entire, dark green, obliquely veined. Flowers 
in crowded, opposite racemes from the upper and smallest 
leaves, and standing so close to the stem, that the whole of 
them seem to form a more or less interrupted and verticillate 
spike, having numerous small, linear, bractee among the 
pedicels. Calyx so deeply divided that it may almost be 
called pentaphyllous, each segment or leaflet ovate, border- 
ed by a white, membranous, and jagged margin, and there 
suddenly contracted into a long and narrow, recurved, pu- 
bescent point or mucro. Corolla small, but of a rich and 
varied purple color, glabrous: upper lip reflected, eee ;
