After having studied the type of Mawillaria speciosa 
in the Reichenbach Herbarium, I am convinced that the 
horticulturally well-known Mawillaria scurrilis is identi- 
cal with that species. Mawillaria speciosa was originally 
collected in Colombia by Klaboch; a recent collection 
by Asplund 17411 establishes its occurrence in Chiri- 
boga, Prov. Pichincha, Ecuador. 
Plectrophora alata (Rolfe) Garay comb. nov. 
Basionym: T'richocentrum alatum Rolfe in Kew Bull. 
197, 1898. 
The type specimen of T'richocentrum alatum in the 
Kew Herbarium shows clearly that the spur of the flower 
is formed by the lateral sepals and not by the lip as de- 
scribed by Rolfe, hence a transfer to the genus Plectro- 
phora is necessary. I have examined material of this 
species from Colombia and Panama. 
Capanemia superflua (?chb.f.) Garay comb. nov. 
Basionym: Oncidium superfluum Rehb.f. in Walp. Ann. 
Bot. Syst. 6: 721, 18638. 
Synonym: Capanemia uliginosa Barb. Rodr. Gen. et Sp. 
Orch. Nov. 1: 187, 1877. 
Rodriguezia anomala Rolfe in Gard. Chron. 
ser. 8, 9: 728, 1891. 
Rodriguezia uliginosa Cogn. in Mart. FI. 
Bras. 8, pt. 6: 169, 1904. 
The holotype of Oncidium superfluum is in the Kew 
Herbarium. On the type sheet, there is an annotation 
by Rolfe indicating that he considers it to be referable 
to Rodriguezia anomala. Cogniaux in Martius’ Flora 
Brasiliensis united Rodriguezia anomala with Capanemia 
uliginosa. Since we are dealing with only one species 
under different names, the above combination is pro- 
posed, in accord with the rule of priority.
