Phragmipedium ramiroi Kolanowska & Szlachetko
in Materials to the Orchid Flora of Colombia, 1: 56, 2017.

Type : Colombia. R. Medina 239b (Holotype: HPUJ!; UGDA! - drawing).

Etymology : This species is dedicated to Ramiro Medina, who collected the type specimen.

Plant : Rather compact plants.
Leaves : Up to 14 cm long, up to 3.5 cm wide, oblong, acute.
Inflorescence : Erect, as long as or shorter than leaves, unbranched; peduncle abbreviated. The flowers are produced in succession. Floral bracts 20-25 mm long, conduplicate, ovate-lanceolate, acute, green.
Flower : Sepals pale pink; petals white flushed with pink at the base, staminode white with a yellow central spot; lip pink, more intensively coloured on the incurved margins. Pedicel and ovary about 36-42 mm long, brown, finely white pubescent. Dorsal sepal about 11 mm long, 6 mm wide, elliptic, obtuse, pubescent, especially on the external surface. Petals about 21 mm long, 15 mm wide, elliptic to obovate, rounded, margins reflexed, finely white pubescent on both sides, with longer, white hairs at the base. Lateral sepals connate into a synsepal 12 mm long, 9 mm wide, similar in shape to the dorsal sepal, keeled on reverse side, margins reflexed. Lip about 20 mm long, 19 mm wide, urceolate, with prominent ridge along mid-vein terminated by hook in the orifice, finely pubescent on outside, with rather long hairs in the basal part and along the middle of the inner surface; lateral margins incurved. Staminode about 7 mm long, 6 mm wide, white pubescent, rhombic, with elongate obtuse apex.

Habitat : Lithophyte on wet rocky slopes in very wet montane forest.

Distribution : This species is endemic to Colombia. Altitude 1600-1700 m.

Flowering Season : In the natural habitat flowering occurs in September and October.

History :

Comments : Eliseo Tesón (2018, personal communication) has visited the population where the plant was collected. He concludes that it is the same as Phrag. anguloi Braem, Tesón & Manzur.
The authors of this species write in the text that accompanies the description: "P. ramiroi is habitually similar to P. anguloi. Both species are rather compact plants with inflorescence as long as or shorter than leaves, but they can be distinguished by some morphological characters concerning flower segments. Relations in size of sepals and petals are similar in size and form, the dorsal sepal of P. ramiroi barely reaches 1 cm long (vs 2 cm in P. anguloi), and synsepal is shorter (up to 12 x 9 mm vs 20 x 15 mm). The lip of our new species if urceolate, ca 20 mm long and wide, whereas in P. anguloi it is nearly as long, but only half as wide as in P. ramiroi. Both species can be determined by staminode morphology - it is elliptic with rounded apex in P. anguloi, and rhombic with somewhat thickened ridge along midvein terminated with elongate obtuse apex in P. ramiroi."
For the moment I will keep it listed as a separate species.
