spt'^cies, which flowers all through the winter. H. Olympicus 

 and some others of the Oriental species are the hotter for 

 slight protection, their early hlossoms being otherwise dis- 

 figured. These and H. atroruhens, purple, March and April, 

 are the most desirable. 



HELONIAS. [Melanthaceae.] Hardy herbaceous peren- 

 nials. Soil, peat, and a damp shady situation. Increased 

 hv division. 



■^ HEMEROCALLIS. Day Lily. [Liliacece.l Hardy 

 coarse-looking, but gay herbaceous perennials, possessing the 

 property of producing blooms that last but one day : hence 

 the trivial name. They are of the simplest culture, growing 

 readily in ordinary garden soil, and are propagated by dividing 

 the plants. Flowers are pretty freely produced from June to 

 August. They are much alike on their claims for a place in 

 the gardens. 



HEMIANDRA. [Labiatae.] Pretty greenhouse ever- 

 green sub-shrubs, allied to Prostanthera. Soil, peat and loam, 

 with a sixth part of sand or charcoal. Inci'eased by cuttings 

 in sand under a bell-glass in heat. H. einargbiata, flowers 

 white and pink, in May. H. jjungeits, flowers rosy purple, 

 in June. 



HEMIGENIA. [Labiatae.] Greenhouse evergreen sub- 

 shrub. Soil, sandy peat and loam. Increased by cuttings in 

 sand under a bell-glass in heat. H. imrpiirea, flowers purple.

HENBANE. See Hvoscyamus. 



HENFREYA. [Acanthaceae.] H. scandens is a pretty 

 stove evergreen climbing plant, bearing panicles of large 

 white funnel-shaped flowers. It requires a compost of turfy 

 loam and peat in equal proportions, mixed v.ith sand to 

 make it porous, and should be repotted in the beginning of 

 summer, after it has ceased to produce its flowers. Propa- 

 gated by cuttings planted in sand, and placed in a close 

 wann frame. 



HEPATICA. [RanunculaccfB.j Pretty dwarf hardy 

 herbaceous perennials. The common Hepatica {H. triloba) is 

 one of the earliest of the spring flowers. These plants require 

 a well-drained border (sandy loam, with one-third peat, is
