There have been quoted by Dr. Lindley two plants under this , 
name, which I believe decidedly different, viz. the H. densiflorwin 
of Sir William Hooker (Bot. Mag. 3791) and &. rubrocinctum, 
Lindl. (Bot. Reg. 1843, Misc. 20). I shall write on both in 
another place. In Walp. Ann. vi. 380, I brought to the same 
neighbourhood the Epidendrum Lansbergu, Regel Cat. Hort. 
Petrop. I havé, however, not seen a type, and the question 
stands in doubt. 
The plant was discovered in Mexico by Ruiz and Pavon! (Brit. 
Mus.!, herb. Boiss.! Rehb. fil.!). Then it was gathered in 
Mexico, near Jalapa, at Hacienda de la Laguna, on shaded rocks 
by Schiede! Barrancas Teosolo Zacuapan; Galeotti! 5125! 
Same place; Leibold! Talea; Hartweg! Guatemala; Bernouilli!
