TROPICAL OK.CHIDADE.aE. 297 



The following epiphytes are easily cultivated in a vinery 

 or a 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 hypmirn or sphagnum, and suspended from the 

 rafters; Dendrobium Pierardi, cucullatum, speciosum; 

 Oncidium **bifolium, papilio, junceum ; Fernandesia ele- 

 gans ; Aeranthes 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, aloefolium, 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 orchidaceae ; 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
