Houlletia lowiana

Houlletia lowiana Rchb.f., Gard. Chron., n.s., 2: 484. 1874.

Type: Colombia, Ocaña, Norte de Santander; Bruchmüller s.n. [locality and collector questionable] (holotype, W-R-19093).

Illustrated specimen: Colombia. Antioquia: Municipality of Yarumal, Reserva Natural Los Magnolios, 1500 m. 27 May 2019. S. Vieira 046 (JAUM; LCDP voucher).

Eponymy: Named after Hugh Low (1824-1905), a British naturalist and orchid collector.

Houlletia lowiana can be easily distinguished from the other species in the genus by its unspotted pale yellow sepals and petals together with patent wide opened flowers. Its most related species, H. sanderi Rolfe, has a very similar coloration, but possesses campanulate flowers. The species has a wide distribution, from Norte de Santander in Colombia to Cochabamba in Bolivia, at altitudes between 1100 and 1800 m.
