Vanda javierae D. Tiu.

A rare and beautiful orchid, it is endemic to the Philippines, occurring on two islands - Luzon and Calayan, in very small areas, at an altitude of 1200m, always close to water sources.
Discovered in the 1980s, this species is considered endangered (EN).
Some scholars already consider it to be extinct in nature.
It is the only white species of the genus Vanda. It is one of the rarest species of the genus.
Due to the beauty of its white flowers, it was collected indiscriminately.

Cattleya milleri (CR)

Cattleya milleri (Blumensch. ex Pabst) van den Berg & M.W.Chase

Basionym: Laelia milleri Blumensch. ex Pabst
Synonym:
Hoffmannseggella milleri  (Blumensch. ex Pabst) V.P.Castro & Chiron
Sophronitis milleri  (Blumensch. ex Pabst) van den Berg & M.W.Chase

Cattleya milleri was described by Dr. Almiro Blumenschein in 1960 in a publication by the Institute of Genetics of the Luiz de Queiroz Higher School of Agriculture (ESAQ) – Universidade São Paulo – Piracicaba.
Guido Pabst, in a publication in Bradea 1367 (1973), mentions an occurrence for Serra dos Ingleses, 1200m. Today it is known that it occurs in other localities.
Pablo Viany Prieto justified the inclusion as a species “Critically Endangered (CR) because it is a species with great chances of disappearing in nature in the near future because it is collection pressure for ornamental purposes, because it is a species with a punctual distribution Quadrilátero Ferrífero (MG) and because it occurs in ferruginous rock fields that have been irreversibly degraded due to mining. These reasons lead us to believe that there is a decline in the number of mature individuals in the population.
