Epidendrum radiatum Hoffmgg., non Lindl., from 
Brazil is known to us only by the description. Its affinity 
is doubtful, but it is included here because both Lindley 
and Cogniaux cite it as probably asynonymof HF. /atilabre. 
Epidendrum corymbosum Ruiz & Pav., non Lindl., 
deseribed from two Peruvian collections, is referred to 
this alliance on the authority of Cogniaux who included 
it as a questionable synonym under EF. difforme. 
Epidendrum virens Hoffmgg., described from ma- 
terial collected near Rio de Janeiro, Brazil,is questionably 
referable to this alliance. It was described as being close 
to H.subumbellatum, but of more slender habit and with 
solitary flowers. It was included with a query in synony- 
my by Cogniaux (in Mart. Fl. Bras. 8, pt. 5 (1898) 139) 
under EF. latilabre. This concept is only known to us 
through the original description. 
Epidendrum arachnoideum Rodr. from Rio de Ja- 
neiro, Brazil, is, judging from the description, only a 
gigantic form of .difforme. 
Epidendrum chlorocorymbos Schltr. The type col- 
lection is Powell 82 from Panama. Specimens of the 
type collection show the papillose-asperate ovary which 
Schlechter mentions as adifferentiating trait, but this trait 
is also more or less present in specimens from Salvador 
and Costa Rica. The lip is much like that of many other 
specimens of /.difforme. 
Epidendrum firmum Reichb.f. The type collection 
is Wendland 1135, from Naranjo-Cartago in Costa Rica. 
Our tracing of the type shows a caespitose plant with 
four stems, the tallest of which is about 15 em. high. 
The leaves are linear-ligulate, the flowers small, the mid- 
lobe of the labellum nearly as broad as long and obcordate. 
Epidendrum majale Schitr. The type collection is 
Ad. Tonduz 17620, from San Ramon, Costa Rica. A 
specimen of this plant proves it to be the same as E. fir- 
[52]
