Epidendrum Ghiesbreghtianum 4. Richard & 
Galeotti in Comptes Rend. Acad. Sci. Par. 18 (1844) 
512, nomen; in Ann. Sci. Nat. ser. 8, 8 (1845) 19. 
Hpidendrum Ghisbreghtianum Schlechter in Beihette 
Bot. Centralbl. 86, Abt. 2 (1918) 462, sphalm. 
This species was originally inadequately described as 
follows: ‘‘Pseudobulbo oblongo diphyllo: foliis lanceo- 
latis: scapo terminali bifloro; sepalis lanceolatis: labello 
amplo pallide violaceo, late subcordato, sinuoso. Aff. 1. 
higulato Va Llave.”’ 
This description alone is too vague to make possible 
any helpful conception of the species, but it is clarified by 
the photograph of the type sheet in the Herb. Mus. Par., 
a tracing of Galeotti’s drawing of the flower in the Rei- 
chenbachian Herbarium and photographs of sheets of 
this species in Herb. Kew. and Herb. Reichenbach. Un- 
fortunately Galeotti’s drawing is somewhat misleading 
as it shows what appears to be the more unusual form of 
lip and has led, we believe, to some confusion. Further- 
more the sheet at Kew containing several collections, the 
data for which is mostly in the handwriting of R.A. 
Rolfe, has at least one envelope the contents of which 
Rolte determined as H.hastatum Lindl., though the visi- 
ble evidence places the material in 7. Ghiesbreghtianum. 
Among the collections of Kpidendrum sent by Mr. 
Ostlund, there was a sheet of what we believed to be a 
new species, but which fortunately Ames suggested bore 
earmarks of 7. Ghiesbreghtianum and a restudy of a pho- 
tograph of the type and other information available has 
convinced us that it represents that species. 
The following amplified description drawn trom the 
newly acquired Ostlund specimens (supplemented by a 
sheet in the United States National Herbarium which has 
been restudied) and the information previously available 
will, we trust, clarify another of the obscure Mexican
