GENERA AND SPECIES 85 



Goodyera Dawsoniana, and plants of similar character. 

 The flowers of most of the species are white. They are 

 sometimes grown in plant cases, or under bell glasses, but 

 if the proper position in a warm, moist house can be 

 found, they are better without these coverings. Propa- 

 gation renews the vigour of the plants and prevents them 

 degenerating, as they often do in cultivation if left undis- 

 turbed for too long a period. 



Ansellia. A fine genus of some half-dozen species 

 peculiar to Natal and Tropical Africa, and growing from 

 one to six feet in height, the leafy pseudo-bulbs having at 

 the top fine, branched spikes of yellow flowers, more or less 

 barred or spotted with purple. Pot as for epiphytal Orchids, 

 and grow in the intermediate house. Water the roots 

 liberally until the flowering is past, and then rest the plants 

 in cool and dry conditions. 



A. africana is not only most commonly grown, but it 

 is one of the finest species. Others, some of which are 

 mere varieties of A. africana, are A. confusa, A. gigantea, 

 A. nilotica, and A. congoensis. 



Arachnanthe. This is a small genus of warm-house 

 plants possessing extraordinary habits, and including the 

 Bornean A. Lowii (Vanda Lowii), a very strong-grow- 

 ing species which bears drooping racemes of greenish- 

 white flowers barred with red. The two basal blooms 

 are dissimilar or dimorphic both in shape and colour, 

 being tawny yellow spotted with purple. The plants 

 should be grown in pots or baskets as Aerides. Other 

 species are A. Cathcartii (Himalaya) and A. moschifera 

 (Malaya). A. Cathcartii will thrive in the intermediate 

 house.
