Andinia auriculipetala is most similar to A. cordilabia and A. werneri but can be distinguished by the acute lateral sepals (vs. apiculate), the reniform, hirsute petals proportionally larger (comparable in size to the lip) with the lobes unequal and the sub-cordate lip ciliate toward the round apex, with the basal lobes oblong and touching above the column.
Type: Colombia. Santander: Vélez province, Municipality of La Belleza, Vereda Vista Hermosa, 2480 m. 11 January 2020. M. Calderón Hernández 190 (holotype: JBB; LCDP voucher).
Andinia auriculipetala has only been found at the type locality, where it grows together with several other species of subgenus Brachycladium (Luer) Karremans & S. Vieira-Uribe such as A. catella (Luer & R. Escobar) Karremans & S. Vieira-Uribe, A. ciliaris (Luer & Hirtz) Karremans & S. Vieira-Uribe and A. irrasa (Luer & R. Escobar) Karremans & S. Vieira-Uribe. It resembles the Ecuadorean A. cordilabia (Luer) S. Vieira-Uribe & Karremans and A. werneri (Luer) S. Vieira-Uribe & Karremans in having an elliptical-ovate, hirsute dorsal sepal; diverging ovate to triangular lateral sepals and an inflorescence positioned almost opposite to the leaves, but can be distinguished by the proportionally larger reniform, hirsute petals with the lobes unequal and . . .

Andinia chaoae belongs to a group of species with ovate, pubescent dorsal sepals, and reflexed non-pubescent lateral sepals with an apiculum. Its in orescence is longer than the leaf and the flowers are facing downwards. Its glabrous, triangular lateral sepals longer than the dorsal sepal easily distinguish it from all congeners except A. cordilabia, A. chelosepala and A. werneri. It can be distinguished from A. chelosepala and A. werneri by the narrowly triangular lateral sepals more than twice as long as wide, its sub-orbicular lip with lateral lobes not extending beyond the column and its pubescent petals.

Masdevallia hortensis is similar to most other species of Masdevallia subgenus Meleagris, it can be distinguished by the callus at the apex of the dorsal sepal and the revolute, white, lateral sepals with a red-purple mid vein. For a long time known only from the type locality where it became extinct by over-collecting, it has been recently rediscovered in two other nearby localities in the Cordillera Occidental in Antioquia and Risaralda, Colombia, where it grows as an epiphyte in shaded and very humid areas of the montane forests around 2600 m elevation.

]]>Platystele colombiana is most similar to P. caudatisepala, P. posadarum and P. baqueroi but can be easily distinguished by the completely glandular-hirsute tepals and the very narrowly linear to acuminate petals that are about a third the width of the sepals, but similar in length.
Type: Colombia, Antioquia: Municipality of Carmen de Víboral, Vereda Santo Domingo, 2170 m. 13 October 2012. S. Vieira & E. Dominguez 0023 (holotype: JAUM; LCDP voucher).
The relatively large flowers with long-cuadate sepals of Platystele colombiana are somewhat reminiscent of P. caudatisepala (C. Schweinf.) Garay, P. posadarum Luer & R. Escobar and P. baqueroi L. Jost & Iturralde. The new species is easily distinguished from those by the completely glandular-hirsute tepals, the very narrowly linear to acuminate petals that are about a third the width of the sepals, but almost the same in length (vs. tepals glabrous [only marginally hirsute in P. baqueroi], petals broader, at least half the width of the sepals, and less than half the length). Platystele speckmaieri Luer & Sijm is also superficially similar with its long-attenuate tepals, with sepals and petals similar in length. However, its flowers are glabrous, tepals are very narrowly caudate and the lip is broad below the middle and contracted apically. . .
