with spreading and reflexed hairs; leaves opposite, subopposite or 
scattered, oblong or elliptic, narrowed from the middle into the very

half, 3-nerved at the base, glandular-pubescent, especially on the 
nerves beneath, 2-12 in. long, 1-3} in. broad; spike elongate, 
bearing numerous closely adpressed white flowers, pubescent with 
spreading and reflexed glandular hairs, 3-4 in. long; bracts sessile,

Schauer, not having seen the fruit, placed this species in the section 
Chascanum (Schauer, |. c.). More complete material shows that its affinities are 
with species of the group Rhagocarpium.

leaves alternate, petiolate, oblong, cuneately narrowed from the 
middle to the base, decurrent on the petiole, obtuse or rounded at the 
apex, coarsely and acutely dentate-serrate above the middle, 
glandular-puberulous above, pubescent with white hairs beneath 
especially on the nerves; nerves very distinet, impressed above, 
prominent beneath; petiole pubescent, 1-3 lin. long; lamina
