 inches long ; . corymbs 2-6 flowered ; petals pinkish-white, 1 \ inc

Ramondia Nataliae. By E. Wocke (Die Gart. p. 533, November 

 20, 1909). — An alpine of recent introduction from the Serbian Balkans, 

 with large close-growing evergreen, hairy leaves, forming a rosette, and 

 numerous large rosy-lilac flowers. Perfectly hardy and easily grown in 

 peaty soil in a cool, shady, and moist spot among rocks. — G. B. 



Ramondia pyrenaica alba. By E. J. (Garden, July 31, 1909, 

 p. 374.) — The plant never appears to such advantage as when on the 

 nearly vertical face of a wall. The seedling forms are variable, the 

 petals often ■ assuming a pinkish tone. Anything approaching root 

 dryness causes the leaves to shrivel. — H. B. D. 



Rhododendron AugUStini. By M. Girard (Le Jard., vol. xxiii., 

 No. 534, p. 158 ; May 20, 1909 ; 1 fig.). — A low-growing hardy rhododendron 

 introduced from China by M. Vilmorin in 1898. It flowers in the middle 

 of May. The foliage is distinct, with russet patches on the under surface ; 

 flowers 7-10 in terminal umbels, 5 cm. in diameter, rosy white, the upper 

 portion spotted with deep yellow ; limb elongated, deeply five cleft ; 

 calyx segments hardly 2 mm. long. Suitable for rock work on the front 

 of a rhododendron bed. It is easily raised from seed, in a cold frame, in 

 spring, in well-drained pans filled with peat and sand ; the seeds should 

 be barely covered with mould. Dust the pans with charcoal, to keep down 

 mosses and Marchantias, or better keep in the dark for several weeks till 

 the seeds have germinated. When the leaves are visible transplant into 

 small pots, and keep in a frame, protecting them for the first winter, after 

 which they can be planted out. They will always, however, need a 

 sheltered position. — F. A. W. 



Rhododendron COOmbense. By W. B. Hemsley (Bot. Mag. tab. 

 8280). — Nat. ord. Ericaceae ; tribe Bhododendreae. China. Shrub, 

 densely branching ; leaves oblong-lanceolate, coriaceous, lj-1^ inch 

 long ; corolla 1|-1J inch across, pale purple. — G. H. 



Rhododendron kamtsehaticum (Die Gart. p. 554, November 20, 

 1909). — Although quite a common Siberian shrub this is not* often met 

 with in gardens. The reason of its scarcity is, no doubt, that it requires 

 quite different treatment from other Rhododendrons. It should be 

 grown in full sun, and treated more as a bog plant, in loam and peat or 

 ordinary peat with sphagnum. It is deciduous and grows from 6 to 18 

 inches in height and has large deep purple or crimson flowers, usually
