82 PRESENT-DAY GARDENING 



fleshy, whitish, or yellow, and spotted with purple or 

 brown. They should be grown in baskets suspended in 

 the intermediate house. A. Barkeri, A. densa, and A. Hum- 

 boldtii are free-growing species. 



Acropera. See Gongora. 



Ada. Cool-house genus from Colombia. Leafy ever- 

 green plants with racemes of orange-scarlet flowers. Ada 

 aurantiaca is almost the sole representative of the genus 

 in gardens, and should be grown even in the smallest 

 collections. 



Aeranthus. See Angrsecum. 



Ae'rides A large genus of evergreen Orchids with 

 distichously arranged, leathery, green leaves, the stem pro- 

 ducing air-roots freely. Natives of India, the Malay 

 Archipelago, and other parts of that region, extending 

 to Japan. 



All the species of Ae'rides may be grown in pots, 

 crocked from one-half to two-thirds of the way up, the 

 old stems of the plants, when long, being placed in the pots 

 before the crocks are filled in. The surface should be 

 of good living Sphagnum-moss, and the plants should be 

 liberally watered from the end of February or beginning of 

 March until autumn, when the supply of water should be 

 restricted according to the condition of growth of the 

 plants. Those which have finished their growth and are 

 not showing new leaves in the centre should be given the 

 least supply, but it is not advisable to dry any off com- 

 pletely, unless for some reason they have to be kept 

 comparatively cool throughout the winter, when they are 

 safest if kept tolerably dry. The smaller species may be 

 grown in baskets with advantage when convenient indeed,
