 with the projecting foot of the column ; labellum 3-lobed,

TRICHOSPORUM (Greek, hair and seed; seeds with 

 1 or more long hairs at the ends). Syn., Mschyndnthus. 

 Gesneriacese. Subshrubs or shrubs, often climbing over 

 trees, glabrous or rather villous, grown in the warmhouse. 



Lvs. opposite, fleshy or leathery: fls. showy, scar- 

 let, greenish or yellow and green mixed, fascicled in the 

 axils or at the ends of the branches, rarely solitary; 

 calyx truncate, 5-cleft or 5-parted; corolla-tube elon- 

 gated, ventricose or broadened above; limb somewhat 

 2-lipped, usually strongly oblique; perfect stamens 4;

These beautiful free-flowering plants are propagated 

 by cutting the branches that have been made during 

 the season of growth into lengths of about 2 inches, 

 having two leaves attached and another joint to 

 insert in the sand. They root in about a month in a 

 close frame when the temperature top and bottom is 

 maintained around 70. Being epiphytal under natural 

 conditions, these plants like a loose open material to 

 grow in, and equal parts of osmunda fiber and sphag- 

 num moss to which plenty of broken charcoal has been 

 added are the best potting material. Shallow pans are 

 best to grow them in, and provision should be made for 

 the water to pass freely through them. The plants 

 should not be allowed to flower the first season, the aim 

 being to secure a good foundation for a future plant, 

 and this is done by pinching the shoots three or four 

 times during the season, growing them in a night 

 temperature of 65. In winter they may be kept 5 

 cooler and given enough water to prevent shriveling. 

 The plants should not be stopped the second season, but 

 allowed to run to flower; but after they have finished 

 flowering they may be pruned back to within 6 inches 

 of the base of the plant. Trichosporums should be 

 grown hung from the roof of the house, near the glass, 

 and when the sun gets strong they should have a light 

 shade. When well rooted in the pan they are growing 

 in, manure-water should be given. These plants are not 

 subject to insect pests. (George F. Stewart.)
