TROPICAL ORCHIDADE^E. 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 hypnum or sphagnum, and suspended from the 

 rafters ; Dendrobium Pierardi, cucullatum, speciosum ; 

 Oncidium ^bifolium, papilio, junceum ; Fernandesia ele- 

 gaus ; 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 5 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 orchidacese ; 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
