Epidendrum validum Schlechter in Fedde Repert. 
Beih. 9 (1921) 95; ex Mansfeld in Fedde Repert. Beih. 
57 (1929) t. 122, nr. 479. 
An examination of typical material of the heretofore 
obscure species, Ivpidendrum cristatum, has convinced 
me of the identity of this concept with the widespread 
plant commonly known as H.raniferum Lindl. E.erista- 
tum apparently does not differ from the usual forms of 
this variable concept except in having more deeply di- 
vided lateral divisions of the lip. These lateral lobes con- 
sist of four divisions of which the posterior one is obliquely 
ovate-lanceolate and the three anterior divisions linear, 
spreading and successively longer toward the front. 
Full synonymy of Mpidendrum raniferum is given in 
Ames, Hubbard & Schweinturth The Genus Epiden- 
drum in the United States and Middle America (1986)

Epidendrum densifolium Avédnzlin in Fedde Re- 
pert. 1 (1905) 186. 
There has recently come to hand a specimen which 
must be referred to 27. densifolium. It agrees well with 
the type collection (of which I have seen an excellent 
photograph) except that the leaves appear to be slightly 
smaller and the inflorescence consists of a spreading pani- 
cle rather than of a ‘‘raceme’’ as described. The detached 
flower-cluster which appears in the type specimen is prob- 
ably a branch of a panicle and shows a strongly fractiflex 
rachis, whereas the rachis of the branches of the panicle 
in my specimen are at most slightly so.
