364 RHODODENDRON 



grow this plant is to plant it in sandy, peaty soil with which a little chopped 

 sphagnum has been mixed, and after it is planted to lay sphagnum round it 

 and amongst the stems also. As it is apt to be cut by late spring frosts it is 

 an advantage to cover the plants with a handlight for a few weeks until that 

 danger be past, or failing that, to select a spot screened from the rays of the 

 morning sun. 



R. KEISKEI, Miguel. 



(Bot. Mag., t. 8300.) 



An evergreen shrub only known as yet in a small state under cultivation, 

 but said to be 6 ft. high in nature ; young branches slightly scaly. Leaves 

 i^ to 2^ ins. long, f to i j ins. wide ; , oval-oblong, pointed at the apex, rounded 

 or tapered at the base, more or less scaly on both surfaces, but especially 

 beneath ; stalk about J in. long. Flowers pale, rather dull yellow, i^ to 2 ins. 

 across, in clusters of about four or five ; corolla broadly bell-shaped ; calyx 

 undulated into five very shallow lobes ; stamens ten, downy ; flower-stalk scaly, 

 ^ to f in. long. Blossoms in April and May. 



Native of Japan ; introduced in 1908, and apparently hardy. Its chief 

 claim to recognition in gardens will be that it is one of the comparatively few 

 species with yellow flowers. The only one of these with which it is likely to 

 be confused is the Himalayan 



R. TRIFLORUM, Hookerfil^ which differs in the leaves being larger, bright 

 green and not scaly above, glaucous beneath, in the more distinctly lobed 

 calyx, the larger pale yellow corolla, and more hairy stamens. R. trifloAnn 

 has been tried several times out-of-doors at Kew, but does not thrive. In. 

 the Isle of Wight, Cornwall, and similar places it succeeds admirably. 



R. KEYSII, Nuttall. 



(Bot. Mag., 1.4875-) 



An evergreen shrub, 6 ft. or more high ; the young shoots, the under-surface 

 of the leaves, leaf-stalk, and flower-stalk densely covered with brownish red, 

 glistening scales. Leaves 2 to 4 ins. long, to \\ ins. wide ; oval-ovate, 

 tapering at both ends ; stalk \ to f in. long. Flowers crowded in short 

 clusters, several of which are borne about midsummer from axillary buds 

 near the end of the previous year's shoot, and at the time of flowering 

 surmounted by the young shoot of the current year. Each flower is | to i in. 

 long, \ in. wide a brick-red, cylindrical tube with five small, blunt, yellow 

 teeth at the mouth ; calyx very small ; flower-stalk in. long. 



Native of Bhotan, up to 10,000 ft. This rhododendron, so remarkably 

 distinct from all others known at the time of its introduction in the curious 

 Correa-like flowers, forms with a recent introduction from China R. spinuli- 

 ferum (g.v.} the sub-genus KEYSIA. It is only hardy in the milder parts of 

 the kingdom, and is a botanical curiosity as well as a rather striking garden 

 plant. Several fine examples exist in Ireland and Cornwall. 



R. LACTEUM, Franchet. 

 (Bot. Mag., t. 8372.) 



A tree 20 or more feet high, the very stout young shoots clothed with 

 down. Leaves clustered at the end of the shoot, narrowly oval, rounded at 

 the base, the apex terminated by a minute tip ; 5 to 8 ins. long, 2 to 3 ins. 

 wide ; dark green and smooth above, covered beneath with a dense red-
