TROPICAL ORCHIDADEZ. 297 
The following epiphytes are easily cultivated in a vinery 
or 2 pine-pit, in pots filled with pieces of peat: Catasetum 
tridentatum, floribundum; Brassia maculata; Oncidium 
flexuosum, pulvinatum ; Gongora atro-purpurea; Cattleya 
intermedia, Forbesii, labiata, crispa; Zygopetalon Mackayi; 
Stanhopea insignis, grandiflora, oculata, tigrina, Devoniana; 
Crytopodium Andersonii; Acropera Loddigesii. The fol- 
lowing kinds are well adapted for being placed in pots 
filled with hypnum or sphagnum, and suspended from the 
rafters; Dendrobium Pierardi, cucullatum, speciosum; 
Oncidium bifolium, papilio, junceum; Fernandesia ele- 
gans; Aéranthes grandiflora; Vanda teres, multiflora; 
Broughtonia sanguinea; Rodriguesia secunda. Some of 
the larger species grow best in rough, black peat-soil, and 
flower freely under ordinary treatment in a stove; such as 
Phajus maculatus; Calanthe veratrifolia; Bletia macu- 
lata; Peristeria elata; Cymbidium siense, aloéfolium, en- 
sifolium. Cypripedium insigne, and venustum. The Va- 
nilla planifolia may be cultivated in the same way; and it 
has been found, that if the retinaculum be carefully re- 
moved from the top of the stigma, and the anther turned 
down to the stigma, the very fragrant fruit of this plant 
may be produced in our stoves. 
A principal object should be to imitate, in some measure, 
the native climate of these orchidacew; to give them a 
dry or hot season, a rainy or watering period, and a cold 
or winter season. Generally speaking, the dry season may 
include May, June, and July; the watering period, August, 
September, and October; and the cold season the rest of 
the year. 
The propagation of these epiphytes is not in general dif- 
ficult. Many sorts form pseudo-bulbs, by means of which 
they are readily multiplied. In others, if the rhizoma or
