320. Nycta'nthes arbor-tristis //. Arbortristis or Night 



Jasmine. (Jasminese.) India. 



A stove plant; growin? three or four feet high; with white flowers; appearing in summer; in- 

 creased by cuttings; grown in light ricli soil. Bot. Mag., 1S56, pi. 4900. 



An interesting small shrub, requiring in England the tem- 

 perature of the stove, where it blooms all summer, opening 

 only at night. The flowers are similar in shape and size to 

 the other Jasmines, but are pleasingly varied by an orange- 

 colored tube and a deep orange eye. It is highly fragrant, 

 and spreads its rich odor to a considerable distance every 

 evening, but at sunrise it sheds most of its night flowers, 

 which in the East are collected for the use of perfumes and 

 dyes. In our climate it would grow freely in the open air in 

 summer, treated like the Vinca and other tropical plants.

321. Cypripedium purpuratum Lindl. Purple-Stained 

 Lady's Slipper. (Orchidese.) Malayan Archipelago. 



a stove plant; growing six inches high; with white and purple flowers; appearing in autumn; 

 increased by offsets; grown in peat and leaf mould. Bot. Mag., 1856, pi. 41)01. 



All the Cypripediums, both hardy and tender, are beautiful 

 plants, and well worthy a place in every choice collection. 

 In Europe they are much prized by all amateur lovers of 

 flowers ; even our common species, so abundant in our 

 woods, are considered an indispensable addition to their 

 gardens. 



The present species has very much the foliage of C. 

 venustum, being elegantly mottled with dark green. The 

 flowers also resemble it, being white, beautifully shaded and 

 striped with purple. Dr. Hooker considers it " a lovely 

 species." It requires the temperature and moisture of a 

 damp stove to flower in perfection. {Bot. Mag., Feb.) 



322. Pentapterygium flaVum Hook. Yellow Pentap- 



TERYGiuM. (Vacciniaceae.) India. 



A greenhouse shrub; growing two feet high; with yellow flowers; appearing in spring; in- 

 creased by layers; grown in peaty soil. Bot. Mag. 1856, pi. 4910. 



" Though not a showy, it is a remarkably elegant and or- 

 namental plant, from the deep-green glossiness of the wrin- 

 kled leaves, and the nodding racemes of yellow flowers,
