Stipa virlettii E. Fourn., Mexic. Pl. 2: 75. 1886.

Comments.

The description of Stipa virlettii (Type: Virlet 1376 from San Luis de Potosí, Mexico) appears to be a mixture of Stipa mucronata Kunth [= Nassella mucronata ] awns and Bromus laciniatus Beal (= Bromus carinatus Hook & Arn.) as determined by A.S. Hitchcock (isotype: US-A866077 fragm. ex P-Fourn-163!). Notes by A.S. Hitchcock on the US sheet with two fragment packets indicate that there are two species of Bromus on the herb. Fournier sheet: A is B. richardsonii Link; B is B. carinatus , also annotated by ASH.
