M. tomentbsa Ait., M. can^scens Lour., (Bot. Mag., t.'250. ; and our fig. 70". ;) 

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

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

 introduced in 1776, and grows to the height of 5 ft. 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 England ; where, in Pontey'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 Vie originated between this and the 

 common species. There is a variety of M. tomentosa in some nurseries, with 

 leaves less downy than the species, which is known as M. afiVnis. 



M. tenuifolia 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 M, communis. It was in- 

 troduced in 1824 ; 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 JV/yrtus are described in Don's Miller, and particularly M. 

 nummularia, a creeping species from the Straits of Magellan, and M. w;yrsi- 

 noides from the colder parts of Peru ; but both of which will probably prove 

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

Chamtzlaucium ciliatum Desf. Mem. Mus., v. p. 40. t. 3. f. B., is a "k 70y 



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 pedicels. The flower is girded by two concave bracteas 

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

 separates transversely. This very singular shrub is not yet introduced. 



Ciilythrix glabra R. Br. (Bot. Cab., t. 587. ; and our Jig. 708.) 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. ericbtdcs Cunningh., Don's Mill., ii. p.;812., is a handsome heath-like 

 shrub, a native of New Holland, in pine ridges at Bathurst, where it 

 grows to the height of from 4 ft. to 6 ft. It was introduced in 1824, and 

 there are plants of it in the Kew Garden. 



Darwima. fasciculdris 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 F LOR A^CEJE. 



THE common passion flower (Passiflora aerulea) 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 

 will 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 

 layers, and grows freely in common garden soil. 



Passiflora ccerulea L. (Bot. Mag., t. 28. ; and our 

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

 which will also grow and flower freely on garden 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 fine 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.
