140 A FEW HINTS ON THE MANAGEMENT OF ORCHIDEOUS EPIPHYTES. 
some: the sepals and petals are greenish yellow^ blotched and marked with bars 
of purple brown; and the labellum is spotted with dark red. It is easily- 
cultivated in turfy peat, in a damp stove, where it can be sheltered from the 
direct rays of the sun. O. Harrisonianum. — The flowers of this species are 
yellow, spotted with a rich brown, are numerous, and borne on a tall slender 
stem springing from the root. We grow it in the stove potted in turfy peat 
and potsherds. It also grows freely amongst moss and rotten wood. 0. pul-chel- 
lum. — The spike of flowers of this species grows from six to nine inches high ; 
the flowers are pure white, except a little orange about the base of the lip, and a 
little rose-colour on the column. 0. ampliatum is a very elegant kind ; the large 
branching raceme of yellow flowers makes a very fine show ; the leaves and bulbs 
greatly resemble those of the 0. papilio. Our plants thrive well potted in turfy 
peat, and placed in a hot damp stove. 0. Carthaginense sends up also a tall spike 
containing many brownish-green flowers, which though not possessing gaudy 
colours, have a handsome appearance. We grow it constantly in the stove, potted 
in turfy peat and potsherds with rotten wood. O. luridum greatly resembles the 
last, but the flowers are somewhat greener ; and in several respects the variation 
is conspicuous when the plants stand side by side. 0. triquetrum — This species 
we do not possess ; but our neighbour, Mr. Cooper, flowered it beautifully at 
Wentworth ; and we think it deserves a place in a first-rate collection. 0. divaru 
catum is very splendid. We have prepared a drawing, which will appear in due 
course. It thrives in the stove, either in pots of turfy peat ; or fixed on wood, 
covered with moss. 0. Lanceanum we possess several plants of, but have not yet 
seen it in flower : it is stated to be a very splendid species. 0. variegalum, 
though not one of the most showy, is yet very beautiful ; the raceme is terminal, 
and contains from eight to ten flowers of a greenish-yellow colour, spotted with 
dark brown. 0. marginatum we do not possess, nor have we seen it in flower ; but 
believe it is handsome. 
Renanthera coccinea is a most splendid plant : it grows very freely planted 
in a pot of moss, and trained either against a wall in a hot part of the stove, or 
against a piece of wood covered with moss. It will thrive all the better for being 
syringed every day with water of the same temperature as the house in which 
it grows. If this be attended to, and the situation be not too shaded, there is a 
probability of the plant flowering beautifully. 
RoDRiGUEZiA secunda is an elegant kind; the flowers are produced on a 
spike about eight or nine inches high, are of a rich rose colour, and very beautiful. 
It is a native of Trinidad, and is easily cultivated in a damp stove, partially shaded 
from the rays of the sun, and potted in moss. R, recurva is not quite so showy as 
the last, but is a valuable kind ; the flowers are yellow. R. planifolia. The 
flowers of this are also yellow, with a tinge of green ; the raceme droops very 
gracefully : it is a very desirable kind. Both this and the last will grow in 
turfy peat well drained. 
Sarcanthus paniculatus. The flower-stem of this species is branching, and 
grows from a foot and a half to two feet high ; the flowers are numerous, bright 
yellow, marked with brownish-red, and have no scent. It thrives potted in turfy
