Discussion:
The new species is probably most closely related to M. floribunda Hook., differing in its larger and longer-acuminate leaf-blades and its essentially glabrous (rather than distinctly castaneous-glandular-strigillose) flowers. The species in this section of Macleania (i. e. the species numbered 1 to 6 in my key in Contr. U. S. Nat. Herb. 28: 360. 1932) are fairly close and are not well represented in herbaria; an eventual reconsideration of specific lines will certainly be desirable. Within this alliance, the new species is close only to M. floribunda and M. angulata Hook., being distinguished from the latter by having its leaf-blades more definitely narrowed at both ends, its flowers solitary and with much shorter pedicels, and its corolla cylindric rather than angled.
