RHODODENDRON. THE ENGLISH FLOWER GARDEN. RHODOTHAMNUS. 805 



leaves are a foot long, covered beneath 

 with a beautiful felt, silvery-white at 

 first, turning brown with exposure. R. 

 racemosum is the most useful and dis- 

 tinct of these new kinds, growing with- 

 out any trouble, and readily increased. 

 It makes a low shrub, well adapted to 

 the rock-garden, growing slowly, needing 

 little root-room, and flowering freely from 

 a height of only a few inches. The 

 white or pale rosy flowers are not large, 

 but instead of confined as in other Rho- 

 dodendrons to a rounded truss at the 

 tips of the shoots, here they also ap- 

 pear all along the shoots as clusters 

 from the leaf-axils, so that in April each 

 branch is transformed into a raceme of 

 flowers. R. rubiginosum, a sca/ce kind 

 which has proved fully hardy at Kew, 

 its flowers bright rose spotted with crim- 

 son. It flowers in late April or May, 

 and is easily increased from home-saved 

 seeds. R. scabrifolium is a pretty little 

 plant, never growing high, with rosy 

 flowers and hairy leaves and stems. R. 

 vunnanense, one of the best, is a beau- 

 tiful hardy kind of slender open growth, 

 doing best in a sheltered spot, where it 

 blooms in -May. The trusses are small 

 but exceedingly graceful, composed of 

 flowers 2 inches or so across, white or 

 rosy-lilac, freely spotted with dark red 

 on the upper petals.

RHODORA (Canadian Rhodora]. R. 

 canadensis is a pretty deciduous bush, 2 

 to 4 ft. high, allied to the Rhododendron, 

 a native of the swamps of Canada, hardy, 

 and needing a moist light soil, though it 

 prefers peat. In very early spring it 

 has clusters of fragrant rosy-purple flowers 

 before the leaves unfold. 



RHODOTHAMNUS./?. chamcecistus 

 is a beautiful little alpine bush very rare 

 in gardens and rather difficult to cultivate. 

 It is less than i ft. in height, with ovate 

 leaves from a quarter of an inch to half 



Rhodothamnus chamaecistus. 



an inch long, thickly clustered on the 

 twigs, the margins set with slender hairs. 

 It flowers towards the end of April and 

 the beginning of May, and produces its 

 blossoms in clusters at the ends of the 

 shoots. From two to four flowers are in 

 the cluster, and each is about if inch 

 in diameter, the free portions of the petals 

 fully expanded. The colour is a pale 

 clear pink with a ring of a deeper shade 

 in the centre. A feature of the flower also 

 is the long stamens. It is by no means 

 rare in a wild state, being found in the 

 Tyrol (often in large patches) as well as 

 in Carniola. In cultivating this plant, full 

 exposure of the foliage to sunlight, com- 

 bined with cool, uniformly moist conditions 

 at the roots are necessary. It should be 

 planted in a sunny position in a crevice 

 or small pocket between the stones, which 

 keep the roots permanently moist and
