Taxonomy and nomenclature

Cynorkis angustipetala was originally described in 1885. However, the name has been applied incorrectly to another species, which is now known as C. speciosa. In 2007, Hermans and Cribb [1] realized that two distinct species were distributed as C. uncinata, which is a synonym of C. calanthoides,[2] and described a new species C. guttata. Subsequently, Hermans and Cribb (2014) [3] realized that C. guttata actually corresponds to what Ridley described as C. angustipetala, and what we have been calling C. angustipetala is C. speciosa. They speculated that this confusion was originated from the type specimen folder of C. anugustipetala, which unfortunately contained a herbarium sheet that had both C. angustipetala and C. speciosa in a single sheet as well as another sheet that had C. speciosa. So subsequent researchers looked at the type specimen folder, and they mistakenly thought that the name C. angustipetala is referring to the green sepal species, which is actually C. speciosa.

Description

Cynorkis angustipetala is also endemic to Madagascar, and its habitat is terrestrial in rocky outcrops and grassland.[1] It is fairly common in the highlands of Madagascar and has sporadic distribution in the east and west of the island. In TROPICOS, there are 2 records of specimens[4] from Antsiranana at the elevation of 225m and 315m. Global Biodiversity Information Facility (GBIF) lists 3 additional records,[5] which include western populations.

gollark: It might be unfathomable dark magic. I can't tell you *much* if you just provide vague descriptions of what happens.
gollark: oh no.
gollark: And it has an XML response type available, I guess.
gollark: I mean, it can do HTTP requests for XML stuff but so can basically anything else.
gollark: They just named it that because XML was trendy at the time.
