botanical literature as Renealmia racemosa (L.) A. Rich. This 
is the only species of Alpinia that was known to Linnaeus ; hence 
it must be the generic type. The proper application of the 
generic name Alpinia is to the numerous American species now 
known as Renealmia, the latter generic name falling as a 
synonym. Among the numerous synonyms of Alpinia auct., 
non Linn., Languas is the earliest available one for the numerous 
Old World species currently but erroneously referred to Alpinia. 
ORCHIDACEAE 
GALEOLA Loureiro 
* GALEOLA sp. 
Cassytha corniculata Burm. f. FI. Ind. (1768) 93, t. S3, f. 1 . “Hab- 
itat in Java.” 
The type was a Javan specimen collected by Kleinhof. The 
reference to Cassutha cornea Rumph. Herb. Amb. 7: 52 must 
be excluded as it refers to the mycelium of Marasmius. Dr. 
J. J. Smith, in answer to my suggestion that Burman’s species 
might be a Galeola, states in lit., July 12, 1918, that he is con- 
vinced that it is either Galeola altissima Blume or G. pterosperma 
Schltr., the drawing representing the upper part of a plant. 
The “thorns” represent the roots; the “floruli imperfecti” 
probably are the young branches or young floral branches which 
often appear in the axils of the scales. 
DENDROBIUM Swartz 
DENDROBIUM CANINUM (Burm. f.) comb. nov. 
Epidendrum caninum Burm. f. FI. Ind. (1768) 189. “Habitat in 
India.” 
Dendrobium crumenatum Sw. in Schrad. Joum. 2 (1799) 237. 
This was apparently based on a Javan specimen, judging from 
the Javanese name cited, angrec utan, and is unquestionably the 
very common and widely distributed species currently known 
as Dendrobium crumenatum Sw. The Rumphian reference An- 
graecum caninum Rumph. Herb. Amb. 6: 105, t. U7, /. 2, repre- 
sents the very closely allied D. papilioniferum J. J. Sm., of the 
Moluccas. I propose to adopt Burman’s name in place of 
Swartz’s for this very common and well-known species. 
* DENDROBIUM sp. § Aporum. 
Epidendrum articulatum Burm. f. FI. Ind. (1768) 189. “In India 
ex arboribus dependet.”
