them like stove heat and full exposure to the sun. The soil 

 best adapted for them is fibrous peat, with a little loam and 

 sand, adding pieces of charcoal to keep the soil open. Hoyas 

 are most readily increased by cuttings, inserted in sandy peat 

 and kept in a moist heat. 



H. hella. — This lovely species is a fine plant for a basket, 

 and has a beautiful appearance thus grown and suspended 

 from the roof of the stove. The leaves are small, opposite, 

 and dark green on the upper side. The flowers are borne 

 upon many-flowered umbels, which proceed from the axils of 

 the leaves, and are waxy-white, with a rosy crimson centre. 

 This is also a beautiful exhibition plant. It is of close, com- 

 pact habit, and should be in every collection. Native of the 

 East Indies. 



H. caniosa. — The leaves of this kind are oval-oblong, 

 pointed, dark green above, and fleshy. The umbels are many- 

 flowered, pendulous ; the flowers pinkish white, and very 

 waxy. It will succeed well in a warm greenhouse, but thrives 

 most luxuriously in a stove. Native of Canton. 



H. coriacea. — A very handsome species, having the leaves 

 ovate-acute, coriaceous, and dark green. The flowers are 

 produced in large umbels, and are of a brownish yellow 

 colour ; its flowering season is from June through the greater 

 part of the summer. These plants have a very pretty efiect 

 when several species are trained upon a pillar or rafter in 

 the stove, a plan which also economises the space very much. 

 Native of Java. 



H. Cumingiana. — A very distinct species ; indeed, when 

 not in flower, it scarcely looks like a Soya. The leaves are 

 closely set, quite thin, obtuse, and dark green. The flowers 

 are white, with a dark brown centre, and very freely pro- 

 duced. It is a very pretty and desirable plant, blooming in 

 early spring. Native of the Philippine Islands.
