Lycoseris Cass., Dict. Sci. Nat. 33: 474 (1824).

Diazeuxis D. Don, Trans. Linn. Soc. London 16(2): 302 (1830). Type: Diazeuxis latifolia D. Don = Lycoseris latifolia (D. Don) Benth.

Type: Atractylis mexicana L.f. = Lycoseris mexicana (L.f.) Cass.

Reference

Egerd, K. & B. St hl. (1991). Revision of Lycoseris (Compositae - Mutisieae). Nordic J. Bot. 11(5): 549574.

Note: Egerd & St hls key and account provides little in the way of discrete characters to separate the two species recorded for Bolivia. Material from the east of Santa Cruz shows much variation in leaf shape and pubescence as well as in capitulum size, even in male capitula. It is quite probable that only one variable species exists and this should be named L. boliviana.
