(Mr Biocklehurst's Houlletia. ) 
Class. Order. 
GYNANDRIA. MONANDRIA. 
Natural Order. 
ORCHID\cEiE. 
Generic Character — Perianth spreading; sepals 
partially free ; petals a little smaller, unguiciilate, 
Labellum continuous with the base of the column, 
spreading ; hypochilium (or lower part) narrow, exca- 
vated at the base, and partially two-lipped, its summit 
prolonged, on both sides, into a lobe, lobes short ; meta- 
chilium none ; epichilium dilated, joined to the hypo- 
chilium. Column erect, arched, club-shaped, semi-cy- 
lindrical, rather shorter than the labellum. Anthers 
two-celled, depressed. Pollen-masses two, opening 
behind ; caudicula linear-lanceolate. 
Specifjc CuAHACT^Ti.'— Plant epiphytal. Pseudo-bulbs 
conical, furrowed. Leaves on long peduncles, broadly- 
lanceolate. Racemes erect, six or seven flowered. 
Sepals oblong, somewhat concave, and, with the petals, 
rounded at the apex. Labellum having the lobes of the 
hypochilium linear-lanceolate, reflexed; epichilium 
ovately- triangular, partially hastate, side-lobes acumi- 
nate. 
For the earliest opportunity of inspecting this remarkable species with which 
we were favoured, we are obliged to Mr. Knight, of the King's Road, Chelsea ; in 
whose orchidaceous house a fine specimen, from which we were allowed to prepare 
the accompanying drawing, developed its blossoms last autumn. Since then, it has 
flowered splendidly at Messrs. Henderson s, Pine-apple Place. 
Dr. Lindley, in his admirable Sertum Orchidaceum, states that it " has in many 
respects the character of Mawillaria, and so much resembles M. Warreana in habit 
that I intended to consider it one provisionally, until I could examine with the 
necessary care the whole of those genera which constitute a division of Yandese, to 
which I propose to assign the name of Maxillaridae. 
" Recently, however, a plant has flowered in the Garden of Plants at Paris, 
which, if not the same species as this, must be very near it, and to which M. Adolphe 
Brongniart has given the name of Houlletia^ after M. Houllet, a zealous French 
gardener, who found it on trees in the Corcovado. I therefore at once adopt the 
genus. 
" In some respects, no doubt, it approaches Stanhopea, also a Maxillaridous 
genus ; but it has a totally different habit, and the hypochilium (lower half of tlie 
lip) is not concave ; on the contrary, it is flat, with a funnel-shaped hollow at its base." 
The same authority informs us that " it appears that the credit of first intro- 
ducing this noble plant from the Brazils is due to J. H. Wanklyn, Esq., of
