A Brazilian epiphyte, nearly related to Epidendrum fra- 
grans, for which I am obliged to Messrs. Loddiges. The 
flowers are straw-coloured, with a few purple streaks on the 
column and at the base of the lip, and have a heavy not 
very pleasant smell, something like that of Ground ivy 
(Glechoma). Of this form of the genus Epidendrum, of 
which Æ. fragrans may be selected as the type, there are 
now several species on record, and it is probable that many 
more remain to be discovered; 1 am already acquainted im- 
perfectly with more than one undescribed species. It will 
therefore be necessary to provide a distinct section for such 
species, to which the name of Oswoprnvruw may be assigned, 
in allusion to their being usually scented plants.

This beautiful plant, whose fleshy root is one of the 
species from which the principal supply of Jalap is derived, 
has been obtained from Mexico by several persons; and has 
lately flowered with Thomas Harris, Esq. of Kingsbury. Its 
slender flowers are of a rich crimson colour, and about four 
inches long. All Botanical observations upon the species I 
reserve till I can publish a figure of the plant; but as it is 
already in the possession of many persons, and will soon 
become common, I am unwilling to keep back the following 
useful notes upon its cultivation, for which I am indebted to 
Mr. D. Beaton, Mr. Harris’s intelligent gardener. 
* [t seems to require a cool atmosphere and plenty of 
room at the roots, and yet the latter are neither numerous 
nor strong. In the stove it grows too vigorously, without 
any disposition to flower. 1 had one plant in a pot all this 
season in the orange house, but if I had turned it out against 
the front of the stove I have no doubt it would have suc- 
ceeded better in regard to flowering. To keep the roots or 
tubers dry from November to March, then to force them 
slightly, and afterwards to harden them, so as to stand the
