been, as far as I am aware, alone known to produce its 

 lovely and most delicate blossoms ; cc the secret" as Mr. 

 Bateman observes, " of its success with Mrs. Wray being, 

 obviously, the comparatively moderate temperature main- 

 tained in her stove, and which appears to be exactly 

 adapted to the OrchidacEjE of the more elevated districts of 

 Guatemala." Baskets filled with moss, or blocks of wood, 

 are found to be most congenial to the roots of Barreria ; 

 — in peat, continues Mr. Bateman, they perish directly. 



Descr. Stems, rather than pseudo-bulbs, four to six 

 inches high, cylindrical, almost as thick as the little finger, 

 somewhat broader upwards, and there producing two or 

 three alternate, oblong, coriaceous, dark-green leaves. Pe- 

 duncle terminal, with a long, brown, sheathing scale at the 

 base, eight to ten inches or more high, bearing seven to 

 nine large flowers, of great delicacy of colour and texture. 

 Sepals spreading, all pointing upwards, lanceolate, acumi- 

 nate, lilac slightly marked with darker spots. Petals ovato- 

 lanceolate, acuminate, of the same colour as, and slightly 

 spotted like, the sepals. Lip large, bent down, clawed at 

 the base, ovate-acuminate, waved, yellowish, spotted and 

 tipped with purple, bearing three elevated plates or lamellae 

 on the disk. Column club-shaped, bent down, as it were, 

 and applied to the disk of the column, deep lilac with 

 darker dots. Anther-case small, operculiform. Pollen- 

 masses four, caudiculate.
