about fifty species, all climbing plants, that belong to 

 the Hot-house. Many are of no ordinary beauty; a 

 few species are odoriferous ; others bear edible fruits, 

 though not rich in flavour. P. data is in our collections, 

 and greatly admired; the flowers are red, blue, and white, 

 beautifully contrasted, and flower profusely in pots. P. 

 racemosa, has red flowers, and one of the most profuse 

 in flowering. P. cceruleo-racemosa, purple and red, 

 and by many thought to be the finest of the genus. P.

 flowered ; it requires to be planted in the ground to 

 make it flower freely, and it will also produce fruit. P. 

 filamentosa is white and blue, and a good flower er. P. 

 picturata is a scarce and beautiful variously coloured 

 species. There are many other fine species, but these 

 are the most esteemed sorts ; and when well establish- 

 ed will flower profusely from May to August. They 

 are desirable in every collection, and will take only a 

 small space to hold them, by training the vines up the 

 rafters of the Hot-house. 



Panddnus, Screw Pine. There are above twenty 

 species in this genus, several of them very interesting, 

 but none so greatly admired as P. odoralissimus. The 

 leaves in established plants are from four to six feet 

 long, on the back and edges spiny ; are spreading, im- 

 bricated, and embracing the stem, and placed in three 

 spiral rows upon it, The top soon becomes heavy 

 when the plant throws out prongs one, two, or three 

 feet up the stem in an oblique descending direction, 

 which take root in the ground, and thus become per-
