fill; the varieties are R. rbsa sinensis rubro plenus, doublt- 

 red ; H. r. s. cdrnea plenus, double salmon ; H. r. s. varie- 

 gains, double striped; striped on the back of the outside 

 petals; 77". r. s. flava, plenus, or carnea, double buff; II r 

 s. littca plenus, double yellow, or rather sulphur. The plants 

 grow freely, and produce their flowers 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 pleno is a splendid plant, of strong growth, 

 and will, when well established, 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 in- 

 dented. H. lillii-fibrus is a new highly esteemed species; 

 the flowers are various in coloar, 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 warmest part of the house. (Soil No. 9.) 



Hoyas, wax-plant, twenty species. All of them are climb- 

 ing succulents, requiring plenty of heat and little water. H. 

 carnbsa is a fine flowering species, and known in our collec- 

 tions 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. cras- 

 sifblia, H. grandifiora, brown flowered, II. bella, variegated, 

 H. Cunninghamii and II. imperialis are all well worthy of 

 cultivation. (Soil No. 2.) 



lpomoeas, a genus of tropical climbing plants, nearly allied 

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

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

 mark. I. 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. 

 I. multiftbra, blush and lilac. I. Learii produces a profu- 

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