greenish pink, and always marked by longitudinal lines 
connected by other transverse ones, which thus form nume- 
rous elevations, and make the flower look like a draught- 
board. The two lower sepals have their inner edge at the 
base rolled inwards like a horn. The /abellum is triangular, 
tongue-shaped, of a pure ivory white, bordered with deep 
purple, and nerved with a deeper tint. Its edges are turned 
downwards, and it is attached to the base of the column by 
a narrow white claw. At the origin of the claw is a crescent- 
shaped plate, hollowed out at its upper edge, and fringed 
with long stiff white hairs, which furrow downwards all the 
part that supports them. 
This charming plant is found in gloomy damp woods on 
the banks of the Rio de Pirapitinga, in the district of Bananal. 
It is scentless, and flowers in June. 
Mr. Rollisson assures me that he received his specimen 
from the same country as that which produced the Zygo- 
petalon cochleare, figured in this work, plate 1857; if so, I 
must have been misinformed as to Trinidad being the native 
country of the latter. I am the more disposed to believe 
that such was really the fact, because I find a drawing, of 
what is e! a luxuriant specimen of Z. cochleare, 
among M. Descourtilz's collection, gathered in Brazil, on the 
high mountains separating the province of St. Paul's from 
that of Minas Geraes, and known by the name of the Manti- 
queiras, where it flowers in the hottest season. 
It thrives very well in the orchideous-house at Tooting» 
where the atmosphere is kept saturated with moisture, and 
the temperature is in winter from 60° to 70° Fahr., and in 
summer from 70° to 90°. The house is of course well shaded 
from the bright rays of the summer’s sun. Like other kinds 
of orchidaceous plants with thick fleshy roots, this requires 
a considerable quantity of water, and should be freely 
syringed. It is grown ina pot, but would probably succeed 
quite as well if hung up, as the greater part of those with 
fleshy roots do much better in that way. 
It is propagated by taking off the young shoots, which it 
sends out rather slowly.
