M. tomentbaa Ait., M. can^scens Lour., {Sot. Mag., t.'250. ; and our^. "07. ;) 

 is a native of China, Cochin-China, and the Xeelgherry Mountains, in tne East 

 Indies, with rose-coloured flowers, which appear in June and July. It was 

 introduced in 1776, and grows to the height of 5 It, or 6 ft. This very hand- 

 some plant is not unfrequent in collections, though it has been seldom tried 

 against a wall, except in the south of Engl.ind ; where, in Vontey's Nursery 

 at Plymouth, and in other places, it has been found quite hardy. In the 

 neighbourhood of London, it might be grafted on the common myrtle ; and 

 surely some interesting hybrids might he originated between this and the 

 common species. There is a variety of .V. tomentbsa in some nurseries, with 

 leaves less downy than the species, which is known as M. aiti'nis. 



M. tenuifhlia Smith in Lin. Trans., ii. p. 380., Don's Miller, ii. p. 836., is 

 a native of New Holland, with leaves an inch long and one line broad ; and 

 with white flowers one half smaller than those of .V. commiinis. It was in. 

 troduced in 18-24; but, as its fruit and seeds have not been examined by 

 botanists, it may probably belong to some other genus. Some other green, 

 house species of 3/yrtus are described in Don's Mil/rr, and particularly .V. 

 nummul^ria, a creeping species from the Straits of Magellan, and M. tiiyrsi- 

 niijdes from the colder parts of Peru ; but tx>th ofwhicliwill probably prove 

 half.hardy, and neither of which have yet been introduced.

Chatruelaucium cUMum Desf. Mem. Mus., v. p. 40. t. 3. f. B., is a 

 native of New Holland, at King George's Sound, a very singular shrub, 

 with opposite, crowded, linear, triquetrous leaves, and axillary white 

 flowers on short ix;dicels. The flower is girded by two concave bracteas 

 before evolution, each terminating in a dorsal mucro, which afterwards 

 separates transver.->ely. This very singular shrub is not yet introduced. 



Cii/i/lfiri-r ^tiibrn K. Br. i^Bot. Cab., t. ;7S7. ; and our Jig. 7118.) is a shrub, 

 a native of New Holland, with small cylindrical leaves, and pale-reddish 

 flowers, which are produced from April to June. It was introduced in 

 1818, and grows to the height of .3 ft. or 4 ft. / 



C. ericb'ides C'unningh., Don's Mill., ii. p.^812., is a handsome heath. like ' 

 shrub, a nati\e of New Holland, in pineiidges at Bathurst, where it 

 grows to the height of from 4 ft. to fi ft. It was introduced in 1824, and 

 Uiere are plants of it in the Kew Garden. ( 



Dartvimn fasciculiXris Rudge in Lin. Trans., xi. p. 299. t. 22., is a de- \ 

 cumbent shrub, a native of New Holland, with red flowers. Introduced ■ 

 in 1820, but not very common in collections. ^

OF THE HALF-HARDY LIGNEOUS PLANTS OF THE ORDER PAS- 

 SI FLORA'cE.^:. 



The common passion flower (Passiflora caeriilca) is so hardy in the neigh- 

 bourhood of London, as to flower freely against a wall, in most years, without 

 any protection whatever during winter. In very dry sheltered .situations, it 

 wiil even endure the open air as a trailing bush ; but as, in this state, it is liable 

 to be killed by winters of unusual severity, unless protected, we have decided 

 on treating the genus as only half-hardy. It is propagated by cuttings or 

 lavers, and grows freely in common garden soil. 



Passi/tora ccertitca L. {Bof. lilag., t. 28. ; and our 

 Jli^. 709.) is a well-known climbing green-house plant, 

 which will also grow and flower freely on ganlen walls, 

 and on the sides of houses with a southern exposure. 

 It is a native of Brazil and Peru, and has been in cul- 

 tivation since 1699. The prevailing colour of the 

 flower is blue ; and that of the fruit, which is egg- 

 shaped, and about the .size of a Mogul plum, is yellow. 

 In fme summers, the fruit ripens in the open air, in the 

 neighbourhood of London, both against a wall, and 

 when the plant is treated as a bush, and allowed to trail 

 along the surface of the ground. It ripened fruit in 

 the last state, in the Goldworth Nursery, in 1835.
