— Pseudo-bulbs in groups, elongated, bearing several narrowly 
lanceolate, fleshy leaves ; scape arising from the summit of the 
pseudo-bulb, slender, with one or two minute scales ; flowers 
in a racemose head, large, delicate lilac, with purple veins; 
labellum obovate, slightly emarginutc, with an undulated 
fringed margin; veined with raised lines, more marked up the

IT^ESCRIPTIOX. — A pseudo-bulbous herb, forming groups of smallish flattened elongated 
&* pseudo-bulbs, marked above by the scars of several scales. Leaves several, elongate- 
lanceolate, fleshy, and sheathing at the summit of the pseudo-bulbs. From the axil of the last 
rises the slender purple scape, bearing at its summit a racemose crowded group of large but 
delicate flowers of a beautiful lilac tint, veined with purple. The flowers arise from, the axils of 
minute triangular membranous bracts ; the ovary is long and slender ; the sepals lanceolate from 
a broad base, acuminated ; the petals like the sepals in colour, but about twice as broad. The 
labellum rolled round the column below, and decurrent into a linear spur adherent to the ovary ; 
its disk when laid open obovate, slightly emarginate, with undulate fringed margins ; veined 
with raised purple lines, most strongly marked up the centre, and tinged here, from the base, 
with brownish yellow. Column less than half the length of the sepals, clavate, semi-terete, 
channelled in front, slightly incurved, the membranous margin of the upper part very narrow.

History, &c. — We believe this plant was found by a friend of H. Gumming, Esq., in the 
Island of St. Domingo, in the West Indies. It was growing on trees in a shady part of the 
forest, along with several other unknown Orchids, among which is undoubtedly a new Lselia. 
Our present subject is a very lovely plant, not less remarkable for its delicate beauty, than for 
the long endurance of its blossoms. The species first flowered with S. Euckcr, jun., Esq., of 
Wandsworth; and afterwards, in May last, with Messrs. Henderson, of Pine Apple Place, in 
whoso nursery our drawing was made. The plant from which it was made, was exhibited 
by Messrs. Henderson, at the May shows of the Horticultural, and Royal Botanic Societies,- 
mid the same plant, still in flower, was again produced at Chiswick, on the occasion of the June 
fete. 
CuLTuitE. — This plant requires the moist heat and high temperature of the Orchid house. It 
should be fastened to a block of wood by means of some metallic wire, and a small portion of 
moss should be placed about its roots. During the season of growth it should be syringed 
every morning with water of the same temperature as the air of the house, and in the 
hottest part of summer, say during the months of June, July, and August, the syringing 
should be repeated in the evening. Whenever the pseudo-bulbs arc fully formed, the 
amount of atmospheric moisture should be lessened, and the syringe used only on two or three 
sunny mornings during the week. Towards the beginning of October, even that may be dis- 
pensed with entirely, and a dry cool atmosphere allowed to prevail; this is to induce a state of 
rest, which is just as necessary to a native of St. Domingo as it is to an inhabitant of the woods 
and dales of ibis country. The excitement of keeping the plants constantly growing, weakens 
their [lowers, so that instead of progressing they lose their energy, ami eventually perish. A 
season of growth and a season of rest is, therefore, necessary. The heat, when the growth is 
going on, should be about 75° by day, and 65" by night. When it is completed, the heat should 
be 60° by day, and 50" by night. The plant is increased bj dfc iding i ome of the oldest pseudo- 
bulbs from the rest, placing (hem upon fresh blocks, and treating them in ever] respect like 
established plants. — A.
