Common Name Langlass' Scelochilus [Belgian Orchid Collector late 1800's]

Flower Size

Found in Colombia and Ecuador at elevations around 2500 meters as a miniature to just small sized, cold to cool growing epiphyte with cylindrical, slightly rugose pseudobulbs enveloped basally by several ditichous, imbricating sheaths and carying a single apical, erect, lanceolate-elliptic, acute leaf that blooms in the fall on a basal, 4 to 7" [10 to 17.5 cm] long, many flowered, widely spaced, racemose inflorescence that arises on a mature pseudobulb through the axil of a basal sheath.,

The 1st photo is certainly the same species as in Native Colombian Orchids #594. The 2nd photo is much closer to the species in Native Ecuadorian Orchids #2124 both of which are cited as Scelochilus langlassei. I feel that one of these most likely is S hirtzii but I have little to go on. Anyone know which one is actually S langlassei I would be happy to hear from you

CAUTION Dodson's drawing of S romansii in Icones clearly shows 2 calli on the lip and 2 horn-like extensions towards the base, If you check Dodson's drawing of S hirtzii it has a smooth lip and the 2 horn like extensions at the base as this one does. In Native Colombian Orchids #594 the flower has 2 calli on the lip and 2 hook-like extensions at the base. Could this one, S romansii, S hirtzii and S langlassei be confused in the publications? Who knows how to sort them out? Are they correct on my site?
