conical, pale yellowish-green, occasionally reddish at its base. Pollen- 
masses four, yellow, attached by a filament exceeding them in length. 
Germen an inch long, furrowed, enlarging upwards, pink. . 
The mode of growth of this plant is curious, and analogous to that of other 
genera among the Orchidee. A bud forms immediately above a joint, 
from this one or more flowering-branches are sent forth, and from the 
origin of these many roots arise: ‘branches with roots in like manner 
proceed from these, and others from these again, each after flowering 
appearing gradually to decay. Perhaps the plant, therefore, would be 
more correctly described as having a simple stem, the only really living 
portion being what for convenience is here called a branch.”—GraHam, 
MSS. | 
This plant was received from Rio through Captain GRAHAM, — 
in 1824, and flowered in the stove of the Edinburgh Botanic — 
Garden in March 1826. From Ep. elongatum it differs in 
the shape and texture of the leaves, and especially in the lip of 
the flower, which has the middle lobe linear, and much smaller 
than the lateral ones, whereas in £. elongatum it is of the 
same ‘size and shape as these. | 7

oldest was.connected with }, close to the surface of the earth, and c, d, 
had their origin at the same time from the point.e, from which they 
were only detached by accident; a, is now quite dead, and.e has little 
life. .d, Has ovato-elliptical concave leaves, while onc, they are ellip- 
_ tico-linear,:and nearly flat. Both.of these stems flowered; but d, the 
one represented in the figure, much more freely. At f, a small swelling — 
has taken place, evidently the point from which d will produce its.suc- 
cessor. There:is no bulb:similar to g,on c.
