Mai/.'] HOT-HOUSE — OF REPOTTING, ETC. 169 
being supposed to represent in the appendages of its flower 
the Passion of Jesus Christ." There are 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. alata is 
in our collections, and greatly admired ; the flowers are red, 
blue, and white, beautifully contrasted, and flower profusely 
in pots. P. racemosa, red flower. P. ccertileo-racemosa, 
purple. P. quadr'angiddris has beautiful red and white 
flowers. The plant is in several collections, but has seldom 
flowered ) it requires to be planted in the ground to make it 
flower freely, and it will also produce fruit. P. picturdta is 
a scarce and beautiful various-coloured species. P. kerme- 
sina, bright rosy crimson, and, beyond all question, the most 
profuse flowering species now in cultivation, and will do well 
in a good green-house. P. Loudonii, bright crimson. P. 
edi'dis is cultivated for its fruit. There are many other fine 
species, but these are the most esteemed sorts ; and, when 
well established, 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. (Soil No. 13.) 
Phoenix, Date-palm, about eight species, principally Asi- 
atic plants. The foliage is not so attractive as many others 
of the palm family, but it is rendered interesting by producing 
a well-known fruit called Date. P. dactylifera will do very 
well in a common green-house. In Arabia, Upper Egypt, and 
Barbary, it is much used in domestic economy. P. palu- 
ddsa has the most beautiful foliage, and the best habit. The 
flowers are dioecious. (Soil No. 12.) 
Plumbago rosea is a pretty free-blooming plant, with con- 
tinued profusion of red flowers; it requires plenty of heat and 
a good drainage. (Soil No. 11.) 
Plumerias, above twenty species. Plants of a slow growth, 
robust nature, and are deciduous. The foliage is greatly ad- 
mired. The plants are shy to flower, but are brilliant in 
colour. P. acuminata has lanceolate, acute leaves, flowers 
corymbose and terminal. P. tricolor has oblong, acute, 
veiny leaves ; corolla red, yellow, and white. This and P. 
rubra are the finest of the genus. They ought not to get any 
water while not in a growing state. (Soil No. 11.)
