711 ARBORETUM AND FRUTICETUM. PART 111. 



B, Species of Bird Cherry Trees which have not yet been introduced, 



1 C. paiiiculdta Lois. (.AT. Du Horn., v. p. 7.), P. panieulata Thunb., not 

 of Bot. Keg., is saiil to be a Japan tree, resembling C. Mahdleb, but differing 

 in having larger and more spreading panicles, smaller flowers, and longer 

 loaves, which are attenuated at the base, and acutely serrated. 



"r C. acuminata Wall. (PI. Par. Asiat., ii. p. 78. t. 181.) is a Nepal tree, 

 growing to the height of 20ft. or 30ft., with the flowers in axillary racemes, 

 and nodding, a little shorter than the leaves. 



I C. mollis Dougl. {Hook. Fl. L\or. Amer., p. 169.) is a tree, from 12 ft. to 

 •24- ft. in height, with the racemes of flowers short, and pubescently tomentose. 

 The leaves obovate-oblong, crenated, and pubescent beneath ; and the fruit 

 ovate. It is a native of the north-west coast of North America, on subalpine 

 hills, near the source of the river Columbia, and also near its mouth. It 

 resembles C. pube'scens (see p. 705.) in habit; and has, like it, the young 

 shoots dark brown and downy. 



s£ C. cmargindta Dougl. (Hook. Fl. Bor. Amer., p. 169.) is a shrub, growing 

 to the height of 6 ft. or 8 ft., with its flowers in corymbose racemes ; oval, 

 serrulated, glabrous leaves ; and globose fruit, astringent to the taste. The 

 leaves are 2 in. long; the flowers are white, and the wood red, with white 

 spots. It is found wild about the upper part of the Columbia river, especially 

 about the Kettle Falls. 



* C. capricida G. Don. The Goat-killing Bird Cherry. Primus capricida Wall., 

 P. undulata Hamilt. in D. Don's Prod. Nepal., p. 239. ; C. undulata Dec. 

 Prod., ii. p. 540. Leaves elliptic, acuminated, coriaceous, glabrous, quite 

 entire, with undulately curled margins. Petioles glandulous. Racemes either 

 solitary or aggregate by threes, many-flowered, glabrous, shorter than the 

 leaves. (Don's Mill., ii. p. 515.) A handsome showy tree, probably evergreen, 

 a native of Nepal, at Narainhetty; where the leaves are found to contain so 

 large a quantity of prussic acid as to kill the goats which browse upon them. 

 Royle seems to consider C. undulata and C. capricida as distinct species; and 

 he observes that these, and " C. cornuta, remarkable for its pod-like mon- 

 strosity, are handsome showy trees, growing on lofty mountains, and worthy 

 of introduction into England." (Royle's Illust., p. 205.) 



3f C. clliptiea Lois. (N. Du Ham., v. p. 4.), Prunus elliptica Thunb., is 

 described in the Flora Japonica, p. 199., as a tree, with elliptic, serrated, veiny, 

 glabrous leaves, and drupes about the size of a small grape.

Engravings. Mill la, 131. t. 196. f. 1. ; Dill. Elth., 193. t. 159. f. 193. ; our fig. 421. ; and the plate of 

 the .species in our Second Volume. 



Spec. Ch'tr.,fyc. Evergreen. Leaves coriaceous, ovate-lanceolate, serrate, 

 glandless. Racemes upright, axillary, longer than the leaves. (Dec. Prod., 

 ii. p. 540.) An evergreen low tree, introduced in 1648, the native country 

 of which ia supposed to be Portugal, or the Azores. 



Variety, 



f C /. 2 Hixa Ser. Primus Hixa Broussonet, according to Willd. Enum., 

 p. 517. ; P. multiglandulosa Cav. in Ann. Sc. Nat., 1801, 3. p. 59. — 

 Leaves larger, with, according to Willdenow, their lowest teeth 

 •.'landed. Racemes elongate. Flowers more loosely disposed. 

 Spontaneous in the islands of Teneriffe, Grand Canary, and Palma. 

 Mr. P. B. Webb informs us that this tree, in its native localities, 

 attains the height of 60 ft. or 70ft. It is much to be regretted that 

 it has not yet been introduced into Britain.
