DESCRIPTIVE LIST OF NEW PLANTS. 
Asterace^e. —Syngenesia Polygamia. 
Echinacea intermedia. This fine, hardy, herbaceous plant grows 
about two feet high, and is of robust habit; the stem is clothed 
with short bristle-like hairs, and streaked with dull brown; leaves 
scabrous, dark green, nearly heart-shaped at the base, verging 
towards the upper part to ovato-acuminate ; flowers showy, four 
or five inches in diameter, bright reddish-purple or blue; invo- 
lucrum green tinged with brown; florets of the ray large and 
spreading; disk elevated. It blooms from the end of July until 
the beginning of November, and is one of the finest of our 
autumnal border flowers. Like all the other species of Echinacea, 
it is, we presume, a native of the cooler parts of Mexico, and of 
recent introduction, but when, or by whom brought to this 
country is uncertain. Syn. Rudbeckia intermedia .*— Pax. Mag.

Coryanthes Fieldingii (Lindley). The flowers are pendulous 
and inverted, so that the apparatus of the column hangs down¬ 
ward, instead of being erect. The general colour of the parts is 
pale brownish-yellow, a little mottled and stained with crimson 
in an irregular manner. When closed, the flower is about five 
inches long, and three inches wide. As it unfolds, the sepals 
and petals, which are membranous, and bear no small resemblance 
to a bat’s wings, turn back, seem to fold up, and finally hang 
drooping at the back of the lip and column, in which organs, as 
is well known, the singularity of the genus resides. The lip is 
borne by a thick horizontal arm an inch and a half long, which 
proceeds from the top of the flower-stalk, and consequently from 
the lower end of the column. Right and left of its base are 
placed two softish, fleshy, pale, ear-like lobes, which are the 
organs of secretion, a sweet fluid continually dripping from them 
as long as the flower is in vigour. At the other end, this 
horizontal arm expands into a convex cap or hood, hairy in front, 
but bald on the crown; a little compressed from the back, and 
two inches across its principal diameter. From the cap hangs 
down a large fleshy goblet, smooth at the edges, flattened at the 
ends, two inches deep, and as many wide, and connected with 
the cap by a hollowed fleshy stalk, which is strongly marked with
