A.) Gravelly table land near Presidio del Norte, parson Parry, Bigelow. Stem apparently 
diffuse, the upright branches 6—10 inches high, slender. Leaves 6-8 lines long, 1-2 lines wide; ` 
| the petiole scarcely a line long. Flowers on short pedicels in the uppermost axils, some of them 
 fructifying without being fully expanded, but mostly with a dilated funnel-form border and a 
tube 1-2 lines long. Stamens and style a little exserted. Fruit as in the preceding species.

The inflorescence at length becomes elongated, the flowers separating from each other and 
forming interrupted or somewhat verticillate spikes. The species is closely allied to B. spicata,

Plant 1-2 feet high. Lower part of the stem slightly pubescent. Leaves i in pairs, unequal in 
size, the larger an inch long and half an inch or more broad. ianth | nearly half an inch in 
diameter with scarcely any free tube, purple. Stamens and style much exserted. . Fruit a line 
and a half long. Near B. linearifolia, but that is glandularly viscid or villous, the leaves are 
usually much narrower and hispid on the margin, and the coste of the күр thick and 
rounded. Dr. Parry collected at the Presidio incomplete specimens of another Boerhaavia, 
which may be undeseribed. It diflers from B. anisophylla in the much larger and more 
diffused panicle, smaller flowers, which are mostly solitary at the ni the кее,
