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 H. rbsa sinensis j 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 H. rbsa sinensis riihro pl6nMSy double 

 red ; H. r, s. cdrnea plenusj double salmon ; IT. r. s. varte- 

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

 petals ] H. r. s. flava plenus, or carneay double buff; IL r. 

 s. lutea plenusj 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. 11. 

 mutdhilis fibre plhio is a splendid plant, of strong growth, 

 and will, when well established, flower abundantly, if the

 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-flbrus 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.) 



HdyaSj wax-plant twelve species. All of them are climb-
