See list of 3 species in this genusReference: Nesom (2001).
-
1a. Leaf blades decurrent on the stem as thin wings [Fig. 446], acuminate at the apex
-
1b. Leaf blades not decurrent on the stem, obtuse to acute at the apex
-
2a. Stems usually with persistent, white tomentum, sometimes only sparsely so, appearing gray or gray-green, eglandular or infrequently stipitate-glandular near the base; capitula wth 4–8 bisexual flowers and 38–96 carpellate flowers; plants relatively inodorous
-
2b. Stems rapidly losing most of the white tomentum, appearing green, covered with abundant stipitate glands 0.1–0.2 mm tall; capitula with (7–) 11–20 bisexual flowers and 47–78 carpellate flowers; plants fragrant
