drainage to the pots, and, when the plants are growing, give 

 a liberal supply of water. (Soil No. 17.) 



HeUtrbpiums, about twelve species, of little merit, except 

 H. peruvianum, H. intermedia, H. valitainana, pale bluish 

 white ) H. fleur de Liejje, represented as yellow, but is only 

 a very diill white, with a faint yellow eye ; these are all 

 very agreeably scented, especially'- the two former^ which, are 

 universal favorites. (Soil No. 3.) 



Hibiscus. This genus affords many fine species and varie- 

 ties of plants for the hot-house, besides others for every de- 

 partment of the garden. The most popular in our collec- 

 tions of the hot-house is //. rosa sinensis, with its varieties, 

 which are magnificent, and flower profusely from February 

 to September. The single or original species is also beauti- 

 ful ; the varieties are //. rosa sinensis richro plSn.ns, double 

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

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

 petals; H. r. s. Jlava j^^enus, or carnea, double buff; //. r. 

 s. liitea 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. IL 

 muidhilis fibre p)reno 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 color, 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-jibrus is a new highly esteemed species ; 

 the flowers are various in color, 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.) 



Hoy as, wax-plant twelve species. All of them are climb- 

 ing succulents, requiring plenty of heat and little water. 11. 

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

 tions as the wax-plant; the leaves are green and fleshy;
