May.~] HOT-HOUSE OF REPOTTING, &c. 165 



three or four inches in diameter, from the young wood; the 

 leaves are ovate, acuminate, smooth, entire at the base, 

 and coarsely teethed at the end. All the varieties are of 

 the same character, and highly deserving of a situation 

 in every collection. There is said to be a double white 

 variety, which we doubt. H. mutabilis fibre, plena is a 

 splendid plant, of strong growth, and will, when well esta- 

 blished, flower abundantly, if the wood of last year is cut 

 to within a few eyes of the wood of the previous year ; the 

 flowers are produced on the young wood, and come out a 

 pale colour, and change to bright red, and about the size 

 of a garden Provins rose ; leaves downy, cordate, angular, 

 five-lobed, acuminate, and slightly indented. H. lillii- 

 florus is a new highly esteemed species ; the flowers are 

 various in colour, being pink, blush, red, and purple. The 

 leaves vary in character, but are generally cordate, crenate, 

 acuminate ; the petioles are brown, and the whole slightly 

 hirsute ; is deciduous, and requires to be kept in the warm- 

 est part of the house. (Soil No. 9.) 



Hoyas, wax-plant, seven species. All of them are 

 climbing succulents, requiring plenty of heat and little 

 water. H. carnosa is the finest flowering species of the 

 genus, and known in our collections as the wax-plant ; the 

 leaves are green and fleshy ; the flowers are mellifluous, 

 five-parted, and in pendulous bunches, slightly bearded, 

 and have every appearance of a composition of the finest 

 wax ; of a blush colour. H. crassifolia has the best-look- 

 ing foliage, and the flowers are white. The former will 

 keep in the green-house, but will not flower so profusely.

Ipomaeas, a genus of tropical climbing plants, nearly allied 

 to Convolvulus, but of greater beauty. /. Jdlapa is the 

 true jalap of the druggists, but not worthy of any other 

 remark. /. Horsfdllia has brilliant rosy crimson flowers, 

 which it is almost entirely covered with from December to 

 May. /. rugosa has a profusion of large rosy lilac flowers. 

 /. multiflora, blush and lilac. /. Learii produces a profu- 

 sion of large blue flowers ; they are all very showy and 

 beautiful ornaments for either the hot-house or the flower 

 garden. (Soil No. 13.) 



Ismene amancaes, or Pancratium amdncaes. This pro- 

 fuse yellow flowering bulb is richly deserving of cultiva-
