98450 to 98481— Continued. 



98460. Rhododendron cephalanthum Franeh. 



A shrub 2 feet high with small elliptical leaves 

 which have brownish wool beneath. The tubular 

 flowers are white. 



For previous introduction see 59029. 



98461. Rhododendron chartophyllum Franeh. 



A distinct species with the general characteris- 

 tics of R. yunnanenese, but the leaves are usually 

 deciduous, more narrowly oblanceolate, and en- 

 tirely wanting the bristles on the upper surface, 

 which are typical of the true R. yunnanense. 

 The form with leaves completely deciduous is 

 called R. chartophyllum prnecox. No doubt the 

 two species, both of which grow in Yunnan, hy- 

 bridize freely, and this probably explains the con- 

 fusion between them in gardens. 



For previous introduction see 97622. 



98462. Rhododendron dasypetaltjm Balf. and 

 Forr. 



A low shrub 2 to 3 feet high, with scaly branch- 

 lets, native to Yunnan, China. The oblong- 

 elliptic leaves, less than an inch long, are densely 

 covered beneath with light-green overlapping 

 scales. The openly funnel-shaped flowers, 1 inch 

 long, are borne in terminal clusters of 1 to 2 flow- 

 ers, and the bright purple-rose corolla is softly 

 pubescent outside. 



98463. Rhododendron fastigiatum Franeh. 



A low erect shrub with scaly branchlets, native 

 to Yunnan, China. The elliptic-oblanceolate 

 leaves, one third inch long, are densely scaly on 

 both surfaces, and the light-purple flowers, one- 

 half inch long, are borne in terminal clusters of 4 

 or 5. 



98464. Rhododendron sargentianum Rehd. 

 and Wils. 



A low alpine shrub up to 2 feet high, native to 

 Szechwan, China. The broadly elliptic mucro- 

 nate leaves half an inch long are reticulate and 

 shining above, clothed with loose flaky scales be- 

 neath. The widely tubular lemon-yellow flow- 

 ers, less than 1 inch long, are densely scaly outside 

 and are borne in loosely capitate few-flowered 

 clusters. 



98465. Rhododendron hippophaeoides Balf. 

 and Smith. 



A shrub up to 3 feet high, native to swampy 

 situations in the Likiang Snow Range, Yunnan, 

 China. The small narrowly oblanceolate leaves 

 obtusely mucronate are covered with contiguous 

 scales above, more densely below; the scales often 

 slightly overlapping are a uniform pale gray. 

 The small flowers, pale lilac to rose, are not 

 spotted. 



For previous introduction see 97625. 



984b6. Rhododendron hypolepidotum 

 (Franeh.) Balf. and Forr. 



A shrub over 4 feet high with scaly branchlets, 

 found in open situations in pine forests at 13,000 

 feet altitude in southeastern Tibet. The oblan- 

 ceolate leaves up to 2 inches long are scaly on both 

 surfaces, the scales below being rather dense and 

 very unequal, flaky, some pale, others darker; 

 lateral nerves distinct. The small yellow flowers 

 are in terminal clusters of 5 or 6. 



For previous introduction see 59076. 



98467. Rhododendron impeditum Balf. and 

 Smith. 



A low shrublet native to the Likiang Snow 

 Range, Yunnan, China, between 15,000 and 16,000 

 feet altitude. The short branchlets are covered 

 with small black scales, and the broadly elliptic 

 leaves, less than 1 inch long, are deeply scaly on 

 both surfaces, the scales below being about half 

 their own diameter apart, more or less uniform 

 but some darker. The openly funnel-shaped

flowers, mauve or light purplish blue, are in ter- 

 minal clusters of 1 or 2. 

 For previous introduction see 59263. 



98468. Rhododendron lysolepis Hutchins. 



A dwarf shrub with erect branches and spread- 

 ing or recurved oblong-elliptic leaves, glistening 

 glandular scaly above and with scattered scales 

 beneath. The deep-violet to pink-violet flowers, 

 1 inch across, in terminal clusters of three, have a 

 short-tubed corolla with the limb spreading at 

 right angles. This specimen was described from 

 plants cultivated at Kew. 



98469. Rhododendron muliense Balf. and Forr. 



A low shrub less than 3 feet high with densely 

 scaly branchlets. The oblong-elliptic leaves, les 

 than 1 inch long, are densely scaly on both sur

 colored outside and maroon inside and are on 

 slender peduncles over 1 inch long.

Mayflower rhododendron. 



An upright Chinese shrub up to 6 feet high, 

 with scaly branchlets, elliptic to obovate leaves 

 which are glabrous above and glaucous beneath,
