ful ; the varieties are H. rbsa sinensis rubro plenus, double- 

 red ; //. r. s. earned plenus, double salmon; H. r. s. varie* 

 gdtusj double striped; striped on the back of the outside 

 petals; //. r. s. flava plenus, or carnea, double buff; H. r. 

 s. liltea 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. If 

 mutdbilis flare 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. //. Ullii-flbrus 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 warmest part of the house. (Soil No. 9.) 



Hoi/as, wax-plant, twenty species. All of them are climb- 

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

 carndsa 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- 

 sifolia, H. grandiflora, brown flowered, If. bella, variegated, 

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

 cultivation. (Soil No. 2.) 



Ipomceas, 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 re- 

 mark. /. 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.. 

 7. muUiflbra, blush and lilac. /. Learii produces a profu- 

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