tegris acutis utrinque viridibus glabris, floribus copiose laxe spicato-pani- 
culatis, involucro unifloro bracteis 4 lanceolatis rigidulis glabris subobtusis,

quam involucrum 3-4plo longiore, limbo quam tubus quadruplo breviore. 
An erect shrub, 6-8 feet high, with slender tetragonous gla- 
brous green branchlets. Petiole sometimes 2-23 in. long; blade
