Distribution:— Venezuela, Colombia, northern and west-central Brazil: Roraima, Pará, Amazonas, Acre, Rondônia, Mato Grosso. TDWG code: 82 VEN-OO 83 COL-OO 84 BZC-MT BZN-AM BZN-PA BZN-RO BZN-RR.

Taxonomic note:— Senghas & Steinhardt (1996) and Castro Neto & Silva (2001) used the degree of adnation of the callus lamellae to separate Acacallis hoehnei and Acacallis rosariana from Acacallis cyanea . We found no morphological discontinuity between specimens putatively identified under these names. In fact, callus structure is variable in the same specimen, even more so between specimens, and so it should not be used as a diagnostic character. Thus, we propose to synonymise Acacallis rosariana and Acacallis hoehnei .

Nomenclatural notes:— The lectotype of Kochiophyton caeruleum had its number changed from 2108 to 2008A by Hoehne (1951, 1953) in order to make it agree with collection sequence of Commiss"o Rondon, possibly due to a typographical error. However, we chose to keep the old numbering, since it agrees with the protologue and herbarium specimen label, which was never altered.

The combination Aganisia rosariana (V.P.Castro & J.B.F.Silva) F.Barros & L.R.S.Guim. is not legitimate due to lack of a basionym citation ( McNeill et al. 2012: art. 41.5).

This is the first time the following names are cited as names in scheda: Pescatoria cyanea , Zygopetalum cyaneum and Kochyophyton caerulerum var. duckeanum .
