coloured, those of G. Plantii being reddish- 

 yellow, G. rothschildiana, scarlet and 

 yellow, and G. superba, shades of orange 

 and scarlet. The flowers of the last-named 

 are curiously crinkled. 



Hoy a. The best of the climbing Hoy as is 

 H. carnosa, known as the Wax Flower. It 

 bears compact, rounded clusters of thick, 

 wax-like blossoms, of a pleasing blush tint. 

 The old flower-heads 

 should not be cut 

 off, as later on flowers 

 will be again produced 

 therefrom. The Hoya 

 will thrive in a mix- 

 ture of loam, peat, 

 brick rubble and sand, 

 and does best in the 

 coolest part of the hot- 

 house. Against a 

 moist wall roots are 

 produced from the 

 stem after the manner 

 of Ivy, and if the 

 shoots are taken off 

 and potted they form 

 separate plants. 



Ipomoea. This is 

 nearly related to the 

 Convolvulus, and the 

 flowers are of similar 

 shape. All the 

 Ipomoeas are free- 

 growing climbers that 

 will soon cover a con- 

 siderable space. They 

 are somewhat liable to 

 the attacks of red 

 spider, hence the foliage 

 should be frequently 

 syringed. All of them 

 need a good compost, 

 such as a mixture of 

 loam, well -decayed 



manure, leaf-mould, and sand. They can 

 be increased by cuttings of the young 

 shoots in spring. A selection of the best 

 includes I. Bona - Nox, white, summer 

 and autumn ; I. Horsfalliae, red, depth of 

 winter ; I. Learii, beautiful rich blue, 

 ; summer and autumn ; and I. ternata, also 

 known as thomsoniana, white, autumn and 

 winter. 



Jasminum. As with the hardier Jas- 

 mines, the flowers of the tropical kinds are 

 very fragrant. They are all plants of simple 

 cultural requirements, and will thrive in a 

 mixture of loam, leaf -mould and sand. 

 Cuttings of the young shoots strike root 

 readily in the spring if put in sandy soil 

 and protected by a close propagating case. 

 The best kinds, all with white flowers, are

 J. Sambac flore pleno. 



Passiflora. Two of the hothouse Pas- 

 sion Flowers, namely, P. edulis and P. quad- 

 rangularis, are often grown for their edible 

 fruits, those of the first-named being about 

 the size of a large Plum, while in P. quad- 

 rangularis they somewhat resemble a small 

 Marrow. Both are vigorous growers, and
