noso cordato trilobo laciniis rotundatis intermediä emar- 
ginatä apice calloso basi 2-tuberculato, spicä globosä 
recurvä.—— Jamaica, Panama, Martinique, Guayana, 
f Grenada. —— One of the most common of all plants in 
some of the tropical parts of America, and varying 
greatly in the size of its flowers and length of the flower- 
stem. Hence have arisen several species, proposed by 
myself and others, which a better acquaintance with 
these plants induces me to believe mere varieties. In 
colour the flowers vary from dull greenish purple to green 
| and almost yellow. Sir W. Hooker’s E. viridipurpureum 
has unusually large flowers, and a flower-stem shorter 
than common ; but in real structure I perceive no differ- 
ence. There is a little difference among these plants in 
the degree of lobing observable in the lip; but I find no 
limit to that kind of variation. 
8. E. orchidiflorum (L. no. 29.); folis distichis lineari- 
| oblongis obtusis, caule apice nudo obtusé vaginato, ra- 
cemo brevi terminali, floribus carnosis, sepalo supremo 
obovato lateralibus oblongis dimidiatis, petalis linearibus 
cuneatis, labello subrotundo basi bicalloso apice triden- 
tato: dente intermedia minore.——Bahia. Leaves 
very small, fleshy and shining. Flower-stem a foot long, 
stout, clothed with blunt somewhat rough sheaths. 
Flowers as large as in the Ep. viridipurpureum of 
Hooker. (Not in cultivation.) 
9. E. fruticosum (L. no. 22.) ; foliis distichis ovato-oblongis 
acutis, caule ramoso fruticoso, racemo terminali nutante, 
sepalis cartilagineis petalisque membranaceis ovato-lan- 
ceolatis acutis erectis, labello subrotundo cordato retuso 
apiculato undulato callis 5 magnis confluentibus in disco. 
— — Mezico.—-— Stem branching, without a trace of 
shéaths, as thick as a crow-quill. Bracts linear-lanceo- 
late, about as long as the ovary. (Not in cultivation.) 
10. E. campestre ; foliis distichis lineari-lanceolatis, pedunculi 
elongàti squamis distantibus appressis, racemo cylin- 
draceo, sepalis lateralibus faleatis labello duplö brevio- 
ribus, petalis conformibus angustioribus, labello subro- 
tundo obsolet® 4-lobo margine integerrimo | basi lineis 
duabus elevatis confluentibus alterá intermedia axin per- 
currente, clinandrio 4-lobo : laciniis quadratis.——
