DESCRIPTIVE LIST OF NEW PLANTS. 
OrchidacEtE. — Gynandria Monandria. 
Oncidimn Barkeri (Lindley). This fine species of Oncidium 
was imported from Mexico some years ago by Mr. Barker, but it 
is still scarce. It is a comparatively small growing plant, with 
oval, compressed pseudo-bulbs, with a furrow or two passing down 
each side. The flowers are disposed in a simple curved raceme, 
and are from five to seven in number, sepals and petals alike in 
form and colour, linear lanceolate, wavy, spreading or turned 
back, the lateral very slightly attached at the base ; they are co¬ 
vered with deep rich brown spots and bands on a pale cinnamon 
coloured ground. The lip is pure yellow without spotting, 
much paler on the under side, and larger than the sepals, middle 
lobe large, broader than long, slightly pointed at the top, which 
curves inwards ; it is distinctly stalked; the entire flower 2-3 
inches across. Like the other species of Oncidium, this requires 
a hot and very damp situation, and also in its growing state a 
liberal supply of water, but when it has perfected its summer 
growth, it should be gradually dried off and have a rest for about 
three months in a cool dry atmosphere.— Bax. Mag. Bot. 
Vanda Violacea (Lindley). This is one of those charming 
epiphytes which are only procured in the fertile regions of the 
East. Mr. Cuming found it in Manilla, and introduced it to 
Europe some seven years since. The flowers are in short pen¬ 
dulous racemes, rather large, with an ivory white ground spotted 
with light violet; of the latter colour there is one large blotch 
within the extremity of each sepal and petal, and a few small 
dots are scattered over their surface ; the lip is wholly violet. 
The flowers have a faint and rather disagreeable smell, which is 
not, however, perceived till they are nearly approached.— Bot. 
Beg. 30—47. 
JEpidendrum plicatum (Lindley). This fine species has been 
introduced from Cuba by Messrs. Loddiges, with whom it 
flowered last January. It is remarkable for the petals, which 
are green inside, with a few purplish stains near the point, being 
of a deep rich violet on the outside. The sepals are greenish, 
stained with dull purple on both sides. The lip is a very rich 
purple, with a little yellow near the base ; its middle lobe is 
strongly plaited, and deeply cordate.— Bot. Reg. 35—47 .
