Pterocaulon alopecuroides (Lam.) DC. [var.] polystachyum DC., Prodr. 5: 454 (1836). Type: ‗ Lin insul.
Caribaeis? (v. s. comm. à cl. Lambert.)‘. Holotype: G-DC. Note: Cabrera & Ragonese (1978: 208) cited the
holotype as in P; this must be considered an isotype.

DC; the ‗h. Mus. Bras.‘ material is almost certainly in P. Lectotype (selected by Cabrera & Ragonese, 1978:
208): ‗Bahìa. Salzman.‘, G. Note: Although lectotypified by Cabrera & Ragonese more precision is needed
and G-DC should be the correct citation. Isolectotype: K.
