Jack's Ivy. Tree. 



Cult. All the species of Ivy are of easy culture. The com- 

 mon ivy and its varieties only require to have slips of them 

 planted where they are intended to remain ; or to be grown in 

 pots until they are the size required, and then finally planted 

 out : the other hardy species should be treated in a similar man- 

 ner. The greenhouse and stove kinds will grow in almost any 

 kind of soil, but the lighter the better ; and cuttings of them 

 are easily rooted under a hand-glass.

Cult. Any light soil will suit the species of Paratropia; 

 and cuttings of them will be easily rooted under a hand-glass in 

 heat. 



XIII. ARTHROPHY'LLUM (from apflpov, arthron, a joint,

ORDER CXXV. HAMAMELl'DE^E (plants agreeing with 

 Hamamelis in important characters). R. Br. descr. pi. chin. 

 1818. p. 3. Adr. Juss. diet, class 8. p. 28. Sweet, hort. brit. 

 371. D. C. prod. 4. p. 267. Pet.Th.veg. afr.austr. ed. 2. p. 31. 



Tube of calyx adhering to the ovarium more or less, 4-lobed 

 (f. 69. a. g.) or repandly toothed. Petals 4 (f. 69. e. i.), linear, 

 elongated, inserted in the calyx, alternating with the calycine 

 lobes, involutely valvate in aestivation : rarely wanting, but 

 probably sometimes changed into stamina. Stamens inserted 

 with the petals, and double their number (f. 69. i.) ; those al- 

 ternating with the petals are fertile, and those opposite the petals 

 are sterile and destitute of anthers (f. 69. g.) ; filaments all short. 

 Fertile anthers inserted by the base, 2-celled, dehiscing in va- 

 rious ways. Ovarium adnate at the base, 2-celled: cells 1- 

 seeded ; ovula pendulous. Styles 2 (f. 69. /.), very rarely 3. 

 Capsule adnate at the base to the permanent tube of the calyx, 

 2-celled, 2-valved ; valves bifid at the apex. Seed pendulous, 

 with a superior hylum. Albumen corneous. Embryo straight, 

 slender, with a superior radicle ; and foliaceous flat cotyledons, or 

 having their margins rather involute. Shrubs. Leaves alternate, 

 bistipulate, petiolate, feather-nerved, entire or sinuately toothed. 

 Flowers axillary, nearly sessile, in fascicles, usually bracteate, 

 sometimes dioecious or polygamous. 



Many of the genera of this order were formerly placed among 

 the Berberidece and Amementaceoe, but were constituted a dis- 

 tinct order by R. Brown in 1818 ; but the place which it should 

 hold in the natural system is still doubtful. According to R. 

 Brown, it is intermediate between Bruniacece and Marlea*, (a 

 genus which should have been placed in Alangieee, vol. ii. p. 806. 

 But according to Pet. Thouars, it comes nearest to RMmneee, 

 and according to Juss. to Haloragiece. But afterwards it was
