NEW AND RARE PLANTS. 105 



agdiust a wall. Dr. Lindley observes that this plant is known in some nurseries 

 under the names of C. ovatus and C. thyrsiflorus, but from both it *is very dis- 

 tinct. The first is a mere variety of C. Americanus, and the latter is a Califor- 

 nian tree, with deep blue flowers, and very strong angular branches. The 

 present species is much hardier than C. azureus, the flowers are of a pale blue. 

 The plant merits a place wherever there is a convenience ; it is easy of culti- 

 vation, grows rapidly, blooms profusely, and is to be obtained very cheap. 



3. Ipomea i.ongifolia, Long-leaved. (Bot. Reg. 21, 1840.) Convolvulacea*. 

 Peutandria Monogynia. A native of Mexico, and introduced into this couutry 

 by the London Horticultural Society. Mr. Hartweg discovered it growing in 

 pastures 'about Leon, and called Quebra platos. It is a hall-hardy perennial, 

 having a long spindle-shaped root, and the stem rising to five feet high, without 

 any branches. It blooms from July to September, each flower opening in the 

 morning and perishing in the evening. The flowers are delightfully fragrant, 

 diffusing a delicious perfume resembling noyau. Each root sends up three or 

 fom shoots, and if taken off when two or three inches long readily strike root. 

 It delights, like most of the Ipomeas, in a strong, rich, but not damp soil, and 

 requires the usual winter treatment given to such roots, taken up, kept dry, free 

 from frost, and excluded from the air as much as possible. The flower is white, 

 with a slight tinge of sulphur, and a rosy -purple centre, each) being about four 

 inches across. It is a most desirable plant. 



4. Impatiens glanduligeua, Glandular. Balsam. (Bot. 'Reg. 22, 1840.) 

 Balsamineae. Peutandria Monogynia. Another of the Indian species raised in 

 1839 in the Garden of the London Horticultural Society, and where it bloomed 

 very freely. The seeds were sown in May, and by the end of August the plants 

 had attained the height of twelve feet. It is not quite as hardy as the kinds 

 having long fruit. The flowers arc of a beautiful rosy-purple colour, each flower 

 being about an inch and a half across. Dr. Lindley remarks that it is one of 

 the most beautiful plants that can be looked upon if grown in an atmosphere it 

 likes.

5. Genista Buacteoi.ata,' Racemose Genista. (Bot. Reg. 23, 1840.) Fa- 

 bacea?. Diadelphia Decandria. A native of Teneriffe, sent to the nursery of 

 Mr. Young, Milford, near Godalming, by Mr. Webb. It requires to be grown in 

 a greenhouse or conservatory. The flowers are produced on terminal racemes, 

 yellow, and flowering freely ; the plant is very showy.

 form and hue of (ruffle, and loses its leaf before the flowers appear, which come 

 up one on either side. The flower is nearly as large as Cattleya labiata, of a 

 fine rose colour, streaked with yellow, and ridges of white tubercles, also having 

 some deep crimson stains on its surface. The flower stem only rises about two 

 inches high. 



7. Osiieckia canescens, Hoaiy-leaved. (Bot. Mag. 3790.) Melastomaceie. 

 Octandria Monogynia. This very beautiful flowering plant has bloomed in the 

 Edinburgh Botanic Garden, where it had been received from Berlin. It thrives 

 and blooms profusely in moderate heat. The plant grows to about seven feet 

 hi^h, and i's lovely flowers are produced in panicles. Each flower is about an 

 inch and a half across, of a fine rcddish4ilac above, paler below. The antheis 

 are of a deep purple. The plant deserves a place in every collection, in a coolish 

 stove, warm greenhouse, or conservator}'.
