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 Lowit), 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 Aérides. Other 
species are A. Cathcartii (Himalaya) and A. moschifera 
(Malaya). A. Cathcartii will thrive in the intermediate 
house.
