H. eViptica, purple ; H. ilicifoUa, purple blue ; H. linearis, 

 H. lonc/ifoUa, purple ; H. jmngens, blue ; H. splendens, blue ; 

 but two or three are as many as one would care for, and 

 H. ilicifoUa is the best of all. 



HOYA. [Asclepiadacere.] A genus of showy plants, 

 mostly climbers, and mostly requiring stove heat. The popular 

 H. cariwsa may, however, be grown in a greenhouse, or, in- 

 deed, in a window, although it also thrives well in a stronger 

 heat. This, an extensively climbing shrub, has umbels of 

 flowers of a peculiar waxy appearance, whitish, with rose 

 colour at the centre, where hangs a drop of limpid honey. We 

 have seen this plant thriving admirably in a Wardian case, 

 placed in a parlour window having a sunny aspect. It is 

 reared by cuttings, which root freely planted in sandy soil, 

 and not too much watered. When rooted they require a 

 compost of loam and peat, and a tolerably large pot ; but it 

 must be thoroughly drained, and some such porous material 

 as broken brick or broken charcoal should be largely inter- 

 mixed with the soil. When the roots get firm hold of a 

 considerable body of such an open compost the branches 

 grow away rapidly, and in a healthy manner, and require only 

 to be fastened in such positions as they are to occupy. Blos- 

 soms are developed in due course ; and here it should be 

 stated that the old bloom-stalks should not be removed, for 

 these put out blossoms year after year — a very singular fact 

 in the economy of this plant. It does not require very large 

 supplies of water, especially in a dormant state. Horja bella, 

 H. imperialis, and H. CunninghamicB are most desirable. 



HUERNIA. [Asclepiadaceae.] Greenhouse succulent 

 evergreen, related to Stapelia. Soil, sandy loam, with a little 

 peat. Increased by cuttings, which should be dried a little 

 before being planted. 



HUGELIA. [Polemoniaceae.] Dwarf hardy annuals, 

 closely related to Gilia, and requiring the same treatment. 

 Light garden soil. They should be sown in the open borders 

 in March and in April. 



HUMEA. [Compositge.] H. elegans is a very elegant 

 greenhouse biennial. It is the graceful form of growth which 

 it assumes that renders it a favourite. The whole plant is 

 not much unlike a pyramidal fountain; the branches shoot out
