OF THE HALF-HARDY LIGNEOUS PLANTS OF THE ORDER DlLLENUVfLE. 



We introduce this 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 loam 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. 



$_ 1. Hibbertia volhbilis Bot. Rep., 1. 126., and our fig. 38., the twining Hibbertia, was introduced 



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



long known, in green-houses and conservatories, 



as Dillenia volubilis, or Dillenia scandens. The 



flowers are about the size of those of Hypericum „ Q 



calyclnum : they are of a bright yellow, and are «j" 



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. Hibbe'rtia dentata R. Br., Bot. Reg., t. 282., 



and our fig. 37., the toothed-leaved Hibbertia, was 



introduced 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 rather 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, when neglected, being killed down to the ground, 

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

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



it. 3. Hibbert\a. grossulario-fblia Sal., Bot. Mag., 1. 1218. The Gooseberry-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 Hibbertia, 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^CEM. 



The characteristics of this order assimilate most to those of Magnoliara?, 

 and those distinctive of it from that order are : anthers with an enlarged 

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

 by the substance of the seed-coat ; leaves without stipules, conduplicate in 

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

 The leaves of Mngno\idce<z are involute in the bud ; and, perhaps, they are gene- 

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

 of this order are included in the genus Asimina Adans., formerly Anona L., and 

 are natives of North America.
