(Fl. Kwangtung & Hongk.) (1912).— Hutchinson in Millais, Rhodod. 

 261 (1917); ed. 2, 260 (1924). 



Shrub sometimes 6 m. tall; branches thin, rigid, glabrous; bud-scales 

 glabrous, ciliate. Leaves crowded at ends of shoots, subcoriaceous, 

 glabrous, oblong-lanceolate to elliptic-lanceolate, 5-10 cm. long, 1.5- 

 4 cm. wide, acuminate, base cuneate, dark lustrous green above, paler 

 below, margin slightly recurved, secondary veins ascending-spreading; 

 petiole 0.8-1.5 cm. long, glabrous. Flowers umbellate, 6-8 or more; pedi- 

 cels stout, 1-1.5 cm. long, glabrous; calyx saucer-shaped with 5 minute 

 rounded or acute somewhat erose teeth, glabrous; corolla lilac-color, 

 funnelform-campanulate, 5-6 cm. long and broad, deeply 5-lobed, tube 

 narrow, 1.5-2 cm. long, lobes spreading, spathulate to obovate, rounded; 

 stamens 10, unequal, shorter than corolla, filaments flattened and papil- 

 lose in lower half; pistil nearly or quite equaling the corolla, glabrous, 

 ovary narrow-ovoid, 0.5 cm. long, furrowed, glabrous, style relatively 

 stout, stigma large, capitate. Fruit not seen. 



Habitat: Kwantung province, Lantao Island, Kowloon, and Swatow, 

 This is a perfectly glabrous species except for a slight pubescence on 

 the basal part of the filaments. It has very numerous ciliolate bud- 

 scales and a several-flowered terminal umbellate inflorescence. The 

 foliage and habit of growth suggests certain species of Pittosporum. 

 The lilac-colored flowers are said to be fragrant. This Rhododendron 

 appears to be a rare and local species and not to have been introduced 

 into cultivation. It was discovered about 1885 by A. B. Westland on 

 Lantao Island; in 1914 W. J. Tutcher found it on the mainland in the 

 new British territory of Kowloon. It was collected on the summit of 

 Phoenix Mt., Swatow in 1905 by S. T. Dunn.

Bush 1 m. or more tall; branches sub verticil late, slender, rigid, gla-

 sometimes obscurely or irregularly serrulate, reticulate, secondary veins 

 spreading, only slightly ascending, branching; petiole 1-1.5 cm. long, 

 stipitate-glandular or glabrous. Flowers umbellate, 5 to several; pedi- 

 cels 1-1.5 cm. long, clothed with short, curled glandular hairs; calyx 

 discoid, with 5 minute rounded or acute ciliolate, often irregularly 

 pectinate teeth; corolla pink, campanulate, 4.5-5.5 cm. long and
