1254 ARBORETUM AND FRUTICETUM. PART III. 



App. ii. Half -hardy Species ofjasmlnum. 



J. odoratissimum L., the Jasmine of Goa (Bot. Mag., t 285.), is a well-known inhabitant of the 

 green-house ; and, being a native of Madeira, it may be kept through the winter in a pit, or 

 against a conservative wall. The flowers are yellow, and extremely odoriferous. 



J. glaucum Vahl is a native of the Cape of Good Hope, with lanceolate leaflets like the leaves of 

 the privet, and white flowers resembling those of J. officin&le, but longer. 



J. azdricum Vahl (Bot. Mas., t. 1889.) is a native of the Azores- and Madeira, with trifoliolate 

 leaves, and white flowers. The shoots twine, as well as climb; and the plant is. doubtless, half- 

 hardy. 



CHAP. LXXVII. 



OF THE HARDY AND HALF-HARDY LIGNEOUS PLANTS OF THE 

 ORDER ^POCYNA V CE^E. 



GENUS I. 



FTNCA L. THE PERIWINKLE. Lin. Syst. Pentandria Monogynia. 



Identification. Lin. Gen., No. 295. ; Juss., 144. ; Lindl. Nat. Syst Bot., 2d edit., p. 301. ; Don's Mill., 



4. p. 95. 



Synonymes. Pervinca Tourn., t. 45. ; laPervenche, Fr. ; Sunngrtin, Ger. 

 Derivation. In Don's Mitter, this word is said to be derived from vinco, to conquer ; because the 



species subdue other plants by their creeping roots, or bind them by their runners : but a much 



better origin seems to be from vinculum, a band, on account of the suitableness of the shoots for 



the purpose of making bands. 



Gen. Ckar., fyc. Calyx 5-cleft ; segments linear or subulate, acute. Corolla 

 salver-shaped ; tube longer than the calyx ; throat bearded ; segments of 

 of the limb flat, oblique, truncate at the apex. Stamens 5, inserted in the 

 throat, enclosed. Filaments short. Anthers ending each in a hairy mem- 

 brane at the apex, which connive over the stigma. Stigma bearded, seated 

 on a flat orbicular disk, which is grooved round the circumference. Glands 2, 

 alternating with the ovaries, glabrous, as well as they. Follicles 2, erect, 

 terete, narrow, dehiscing lengthwise, few-seeded. Seeds cylindrical, naked. 

 Albumen fleshy. (Don's Mill., iv. p. 95.) The hardy ligneous species 

 are creeping evergreens ; natives of Europe, in shady places; of the easiest 

 culture ; and readily propagated by division, layers, or cuttings.

Spec. Char., $c. Stems erectish. Leaves ovate, acute, ciliated. Calycine 

 teeth linear-subulate, ciliated, usually with a small tooth on each side at the 

 base. Segments of corolla broad, obovate. This species is larger in all its 

 parts than the preceding. Corollas fine purplish blue. Flowering stems 

 erect; barren ones trailing. There is a variety of this with variegated 

 leaves. (Don's Mill., iv. p. 95.) A low, trailing or creeping, suffruticose 

 evergreen ; a native of the middle and south of Europe, and apparently 

 wild in some parts of Britain. It grows as high as 2 ft., forming a dense 

 dark green, low, trailing bush, growing freely under the shade of other 

 trees ; and producing its fine blue flowers from March to September. 



Variety. 



'&, V. m. 2 variegdta Hort. has the leaves variegated with white and 

 yellow.
