perennials, with one or two exceptions. Some of them are 

 prett3% producing a number of small flowers, usually white, 

 on much-hranched stems. All the smaller species of the 

 genus, which is rather extensive, are well adapted for rock- 

 work. They like a dryish soil, especially if intermixed with 

 calcareous matter, or old lime, or brick rubbish. They nmst 

 be propagated by seeds or cuttings, their tap-rooted habit not 

 generally admitting of safe increase by division. 



HABENARIA. [Orchidacese.] A genus of herbaceous 

 perennials, containing one or two hardy species. Soil, moist 

 peat. Propagated by division. 



HABRANTHUS. [Amaryllidace*.] Greenhouse bulbs 

 with showy flowers. Soil, sandy loam, with one-third peat. 

 Propagated by offsets or by seeds. They flower without the 

 leaves after a season of rest. 



HABROTHAMNUS. [Solanace^.] Elegant greenhouse", 

 shrubs of laige growth. They are very showy when planted 

 out in a cool conservatory, either in borders or against pillars 

 or the back wall ; but in pots they are incommodious, requiring 

 to be grown very large in order to obtain a free development 

 of flowers. They may be grown on conservative walls if tlie 

 branches and roots are sheltered from wet in winter, and the 

 soil is thoroughly drained, and not too rich, so as to check 

 exuberant growth ; but their habit under such treatment would 

 be somewhat changed. Soil, rich loam and peat. Propagated 

 very readily by cuttings. H. jnirpureus, H. elegans, and H. 

 fasciculatus are good. 



HACQUETIA. [Umbellifer^.] A small hardy herba- 

 ceous perennial. Soil, sandy loam and peat, Incieased by 

 division. H. epipactis, flowers yellow, in Api'il. 



H^MADICTYON. [Apocynacese.] Handsome evergreen 

 stove twining shrubs, allied to Echites. Soil, fibry peat and 

 loam, with a sixth part sand. Propagated by cuttings in saiid 

 in a hotbed, under a bell-glass. H. venosuni has beautiful 

 red-veined foliage. H. suherectum and H. venosum flower 

 yellow, in July. 



H^MANTHUS. Blood Flower. [Amaryllidaces. • 

 Greenhouse bulbous plants, most of them not very showy. 

 Soil, sandy loam, with an equal portion of peat, old cowdung, 

 and sand. Increased by off'sets. There are numerous species
