unequally three-lobed, the two lateral divisions about a line and half 
long, round, obtuse, with the margins bent down; the central division 
narrow at the base, then broadly rounded, almost reniform, and two- 
lobed; the crista on the base of the labellum consists of a number of 
tubercles, of which four or six are more prominent than the rest. 
Cotumna also yellow, about three lines long, with an oblong or semi- 
ovate, somewhat falcate, wing on each side. 
Poputar AND GeocrapHicaL Notice. This beautiful genus 
forms one of the great ornaments of the woods in the hotter parts of 
America, ,especially in the West Indies; and the tierra caliente of 
Mexico, by the very graceful manner in which its numerous species 
hang from the stems of the trees. One species, closely allied to the 
present, is the plant cotmmonly selected by the Mexican Indians 
to adorn their graves, and many have long been cultivated in the West 
Indian islands for the beauty of their flowers. The species here 
figured, which is very nearly allied to Oncidium —— is a 
Mexican plant. 
InTRoDUcTION; WHERE GrowN; CutTure. The Oncidium re- 
flexum was first introduced into this country, it is believed, by Messr 
Loddiges of Hackney, who were, at any rate, the first to flower it, in 
their unrivalled collection. Our figure was taken from a well flowered 
plant in the collection of G. Glenny, Esq. of Worton Lodge; who 
obligingly favoured us, at the same time, with a specimen of a new 
Correa, to which we hope to pay early attention. This is one of 
that splendid tribe of orchidaceous plants called Epiphytes (from «7+ 
EPI upon, and $vTov PHUTON a plant) in contradistinction to those 
which are terrestial, or grow on the earth. It should be observed that 
these plants are not parasitic: although they grow upon other plants 
they do not, like our mistletoe, receive nourishment from them. De- 
cayed yegetable matter, lodging amongst their roots, may have some 
influence on their luxuriance; still, however, these Epiphytes are prin- 
cipally dependent on a warm humid atmosphere for their successful 
growth. “We have found, says Dr. Lindley, that no soil or tempera- 
ture would nourish them in drought, and that any soil was good when 
the temperature and atmospheric humidity were carefully regulated. 
To speak very accurately upon these points, we should say that the 
mean temperature of the air, in the day, ought to be 87° or there- 
abouts, and that its* humidity should be at the ey of saturation, or 
nearly so
