53728. Rhododendron davidsonianum Rehd. and Wils. 



"A western Chinese shrub 10 feet high, with thinly coriaceous 

 leaves glaucescent beneath and rosy pink, bell-shaped flowers 1 inch 

 across." (Alfred Rehder.) 



53729. Rhododendkon decokum Franch. 



"A western Chinese shrub with glabrous leaves glaucous beneath 

 and broadly bell-shaped white or pink flowers 2 inches across." 

 {Alfred Rehder.) 



53730. Rhododendron racemosum Franch. 



An evergreen shrub, 5 or 6 feet high, one of the most distinct and 

 pretty of the dwarfer Chinese rhododendrons. The soft pink flow- 

 ers, 1 inch across, widely bell shaped, are produced from the leaf 

 axils of the previous year's wood. Often 6 to 12 inches of the shoot 

 is laden with flowers. It is a charming plant for grouping in low 

 shrubberies. (Adapted from Bean, Trees and Shrubs Hardy in the 

 British Isles, vol. 2, p. 37 Jf.)

53731 to 53743. Rosa spp. Rosacece. Bose. 



53731. Rosa cinnamomea L. 

 (R. pendulina L.) 



Variety pyrenaica. 



A graceful rose gene'rally less than 2 feet high, said to be plenti- 

 ful in the Pyrenees. The rosy red flowers, 2 to 3 inches in diameter, 

 resemble in outline and form the dog-rose of England; the berries 

 are also ornamental. The plant is well suited to rock gardens, but 

 must not be allowed much root room, as it becomes too rampant. 

 (Adapted from The Gar-den, vol. 27, pp. 5Jf5, 560, and 587.) 



53732. Rosa davidh Crepin. 



A pink-flowered, orange-fruited rose, 3 to 18 feet high, native of 

 western Szechwan, China, at altitudes of 4,000 to 9,000 feet. It 

 is the species in China nearest to Rosa macrophylla of the western 

 Himalayas. (Adapted from Sargent, Plantae Wilsonianae, vol. 3, p. 

 322.) 



For previous introduction, see S. P. I. No. 43886. 



53733. Rosa davidii elongata Rehd. and Wils. 



A western Chinese form with leaflets 2 to 3 inches long, fewer 

 flowers than in the species, and fruits about an inch long. (Adapted 

 from Bailey, Standard Cyclopedia of Horticulture, vol. 5, p. 2997.) 



53734. Rosa longicuspis Bertol. 

 (R. sinotvilsoni Hemsl.) 



A rambling bush about 20 feet high, native to western China; 

 with sparse, short prickles, large, dark-green leaves, and very large 

 lax corymbs of white flowers which are up to 2 inches wide. 

 (Adapted from Kew Bulletin of Miscellaneous Information, 1900, 

 p. 158.)

53735. Rosa mollis Presl. 



A compact Asiatic rose, often not more than 3 feet high, with 

 usually pink, occasionally white, flowers and early ripening, red, 

 pulpy fruits which are often pendulous and are very ornamental.
