A study of the genus Samolus has revealed this hitherto un described species; it is related to Samolus alyssoides and S. ebrac teatus, from both of which it may be distinguished by the glandular-pilose peduncles and smaller corollas. The corollas of specimens of Samolus alyssoides and S. ebracteatus which I have examined vary from 6-9 mm. in breadth, while those of S. cmre atus are only 4-5 mm. broad. The corolla-segments of the new species are broadly cuneate as contrasted with the suborbicular segments of the two older ones.
The following specimens belong to S. cuneatus Texas : Kerrville, Kerr county, May 14-21, 1S94, A. A. Heller, no. 1751 (type); Waco, 1887, Miss Sara Trimble.
