PART HI. 



OF THE HALF-HARDY LIGNEOUS PLANTS OF THE ORDER DlLLENIjV^^". 



We introduce tliis order chiefly for the sake of recommending some species of Hibbert/a as half- 

 hardy climbers. All the hibbertias are either natives of the Cape of Good Hope, or of Australia ; 

 and, probably, the whole of them might live against a wall with protection. They grow freely either 

 in sandy loain mixed with leaf mould, or in sand and peat ; and they are readily increased by cuttings, 

 either of the young or of the ripened wood. 



i_ 1. Hibbert\& volhbilis 'Bot. llep., t, ISJG., «7;rf o!<r fig. S8., the. twining Hibbertia, yi&s introduced 

 from the Cape of Good Hope in 1790, and has been 

 long known, in green-houses and conservatories, 

 as Dillenin voUibilis, or Dillfenia scandens. The 

 flowers are about the size of those of Hypericum 

 calyciniTOi : they are of a bright yellow, and are 

 produced all the season, from the beginning of May 

 to the end of October. The plant is a vigorous 

 grower; and, in conservatories, will extend to the 

 height of 8 ft. or 10 ft. in about as many years. 



2. HibMrtia. denttda R. Br., Bol. Reg., t.282., 

 and our 'r^.'oI., ttte toothed -leaved Hibhertia, was. 

 introducccl from New Holland, where it grows on 

 the Blue Mountains, in 1814. It is a vigorous- 

 growing twiner, like the preceding species, with 

 narrower leaves and ratlier smaller bright yellow 

 flowers, which are produced from February or 

 March till August. It has been tried in the open 

 air in several places, and found to stand the winters 

 of London with very little protection ; sometimes, ^vhen neglected, being killed down to the ground, 

 but shooting up again the following spring. One in our garden at Bayswater has stood since 1831 j 

 and one in the garden at Bicton, near Exeter, since 1833. 



a~. 3. HibbM'm grossulnri<efblia Sal., Bat. Mag., t. I'ilS. TJie Gooseherry-leaved Hibbertia. — This is 

 an elegant trailer, from New" Holland, which has been in cultivation since 1816. The leaves are 

 nearly round, beautifully notched ; and the flowers are on peduncles opposite the leaves, and of a 

 bright yellow. It is rather a procumbent than a climbing plant ; but thrives well against a wall, or 

 on rockwork, during the summer months. 



Other Species of Bibbertia, from New Holland, are in cultivation in Britain ; and upwards of a dozen, 

 which have been described, remain to be introduced ; all of which, there can be no doubt, will 

 stand our British winters with little protection, and produce a fine show of their brilliant yellow 

 flowers during the summer months. 



CHAP. V. 



OF THE HARDY LIGNEOUS PLANTS OF THE ORDER ANONA^CEJE. 



Thk characteristics of this order assimilate most to those of Magnolmctw, 

 and those distinctive of it from that order ai-e : anthers with an enlarged 

 four-cornered connectivum, which is sometimes nectariferous ; albumen pierced 

 by the substance of the seed-coat ; leaves wdthout stipules, conduplicate in 

 the bud; properties aromatic. {Lindl. Introd. to N. S., and Don\s Mill.) 

 The leaves of Magnolirtcefz? are involute in the bud ; and, perhaps, they are gene- 

 rally less obviously feather-nerved than those of AnondcecB. The hardy species 

 of this order are included in the genus Ashnina Adans., formerly Ajiona L., and 

 are natives of North America.
