Type.

ECUADOR. Napo [ Sucumbíos]: Páramo de Mirador above Cocha Seca, lower páramo zone, burned, 00°34'N; 77°39'W, 3700-3900 m alt., 23 May 1985, S. Lægaard 54413 (holotype: AAU!; isotypes: K (K000308461!), MO (MO05100301 [image!]), QCA (QCA78857 [image!]), QCNE, US (US00588939!)).

Comments.

Previously considered endemic to Ecuador with a global conservation status of VU B1ab(iii) - Vulnerable ( León Yánez et al. 2011). The voucher specimen collected matches the species description in every aspect apart from its having two anthers as opposed to one. The number of anthers is taxonomically informative in the genus Calamagrostis and it may be that the Sylvester 3049 specimen should be considered as a distinct taxon, although further research including molecular analysis is needed to clarify this. Laegaard (1998) noted that Calamagrostis carchiensis bears affinity to Calamagrostis bogotensis (Pilg.) Pilg., especially in terms of florets with a single anther.
