HABENATtlA.— 0?t/; Iddcece.— 

 Hardy North American peren- 

 nials, with tuberous roots, and very 

 curiously-shaped flowers, which are 

 generally yellow, but sometimes 

 pui-ple, and sometimes white. They 

 grow best in a shady situation, and 

 in a peat soil, kept rather moist 

 than dry. 



Habra'nthus. — AmaryUldacece. 

 — Bulbous-rooted plants (some of j house; they should be grown in peat 

 which will thrive in the open grounds [ and sand mixed with a little loam, and 

 though others require a greenhouse, j the pots should be well drained, and 

 and others a stove), the culture of never suffered to become either too 

 which exactly resembles that of the 

 Amaryllis. The flowers are also 

 similar, though very much smaller ; 

 and, as in the Amaryllis, they are Snowdrop-tree. American low trees, 



very coarse-growing, and take up a 

 great deal of room. H. mxdtifldrus 

 is, however, an exception, as it is 

 rather pretty. 



H^MATOXYLON. — LegiLminoscs . 

 — The Logwood. This tree, which 

 grows about twenty feet high in its 

 native country is a stove shrub in 

 Britain. It has yellow flowers, and 

 should be grown in a mixture of peat 

 and loam. 



H A^KE A. -Prof ea ceoe. - A ustralian 

 shrubs, with flov/ers somewhat resem- 

 bling those of the Grevillea, which 

 are frequently sweet-scented. The 

 plants are generally keptin thegreen- 



produced before the leaves. The 

 Habranthus appears to exemplify the 

 doctrine of bulbs being under-ground 

 stems ; for we are told by the late 

 Hon. andRev.W. Herbert ( Sof. 3/o^/. 

 t.257), that the bulbs of this species, 

 though round when imported, after 

 having been potted a year, become 

 gradually elongated. Plants of this 

 genus are generally grown in a mix- 

 ture of sandy loam and peat ; and 

 for the details of their culture, see 



AlIAKY'LLIS. 



H ABROTHA 'mnus, — Cestvcicece. — 

 Very elegant jMexican shrubs, bearing 

 a profusion of rose-coloured tube-like 

 flowers in the middle of winter. A 

 plant of H. elegans, planted in the 



which generally form very handsome 

 hardy shrubs in British pleasure- 

 grounds. The reason of this is, that 

 in North America the species all 

 grow on the banks of rivers, in very- 

 poor rocky soil, whereas in England 

 they are grown in dry places in rich 

 soil ; and too much nourishment to a 

 tree which does not require it, has the 

 same effect as too much animal food 

 to a child — it makes it increase in 

 width instead of height. The Snow- 

 drop-tree flowers freely, and its stem 

 droops gracefully over water. The 

 flowers are white, and resemble those 

 of the Snowdrop ; and the seed is 

 curiously winged. The species will 

 grow in any soil or situation, but 



«ight months in every year
