Rhododendron kailiense Fang et M. Y. He in Bull. Bot. Res. 2(2): 83. Pl. 2. 1982 et in Journ. Rhodod. Spec. Foundation 1: 101. 1984.
乔木，高4-5米，胸径15厘米；当年生枝棕褐色，无毛，多年生枝灰褐色。叶革质，宿存，近于轮生，长圆形或长圆状披针形，长8-14厘米，宽2.5-4厘米，先端锐尖，基部楔形或宽楔形，边缘微反卷，上面绿色，中脉微凹陷，下面淡白色，中脉凸出，侧脉不显著；叶柄长约1.3厘米，无毛。花的特征不详。蒴果圆柱形，长9-10厘米，直径5毫米，基部拱弯，近于直角，常5枚簇生枝顶叶腋，花萼宿存；裂片呈宽线形，长达1.7厘米；果梗长1.8-2厘米，无毛。果期8-9月。
产贵州西部。生于海拔1 340-1 540的山谷密林中。模式标本采自贵州凯里（雷公山）。
本种近于长蕊杜鹃R. stamineum Franch.和毛棉杜鹃花R. moulmainense Hook.f．但不同在于本种的蒴果长达9-10厘米，长圆柱形，基部弯曲，通常4-5（-9）枚簇生枝顶叶腋；宿存的萼片长达1.7厘米，易于区别。
形态特征：乔木，高4--5米．胸径15厘米； 当年生枝棕褐色， 无毛，多年生枝灰褐色。叶革 质，宿存，近于轮生，长圆形或长圆状披针形，长8—14厘米，宽2．5—4厘米， 先端锐 尖，基部楔形或宽楔形，边缘微反卷，上面绿色， 中脉微凹陷， 下面淡白色， 中脉凸出， 侧脉不显著；叶柄长约1.3厘米；无毛。花的特征不详。蒴果圆柱形， 长9—10厘米，直 径5毫米，基部拱弯，近干直角，常5枚簇生枝顶叶腋，花萼宿存；裂片呈宽线形，长达 1．7厘米；果梗长1．8--2厘米，无毛。 果期8—9月。
产地分布：产贵州西部。生于海拔1 340--1540的山谷密林中。模式标本采自贵州凯里(雷公山)。
本种提示：本种近于长蕊杜鹃R．Stamlneum Franch．和毛棉杜鹃花R．Moulmainense Hook． F．但不同在于本种的蒴果长达9--10厘米，长圆柱形，基部弯曲，通常4—5(--9)枚簇 生枝顶叶腋；宿存的萼片长达1．7厘米，易于区别。

Rhododendron westlandii Hemsley
凯里杜鹃 kai li du juan
Erect shrubs or small trees, 3–5 m tall; branchlets stout, cylindric, pale gray-brown at maturity, red-brown when young, glabrous. Petioles stout, ca. 10 mm. Leaf blade thickly leathery, long-elliptic or subelliptic to oblong-lanceolate, 5–12(–21) × 2.5–5(–8) cm; base cuneate to rounded; apex acute or with a sickle-shaped acumen; both surfaces glabrous; lateral veins 14–18-paired, becoming conspicuous on both surfaces on drying. Inflorescence terminal, umbellate, 5–6-flowered; peduncle short and stout, ca. 5 mm, glabrous. Pedicel 1–1.5 cm, glabrous; calyx usually obscure, sometimes developed and then lobes membranous, linear, to 17 mm, pubescent, margin sparsely fimbriate-ciliate, apex obtuse or two-forked; corolla funnel-campanulate, white or pinkish to rose, with yellow flecks on upper part of inner surface of lobes, ca. 5 cm, tube ca. 15 mm; lobes obovate or ovate, ca. 3 cm; stamens 10, 3.5–4(–4.5) cm, filaments white-pubescent below middle; ovary tapering into style, ca. 8 mm, glabrous; style stout, slightly longer than stamens, glabrous. Capsule cylindric, sometimes with base curved through almost 90 degrees, 90–100 × ca. 5 mm. Fl. Apr–May, fr. Sep–Dec.
Dense forests, thickets, open areas by rivers, near rocks; 400–1500 m. Fujian, Guangdong, Guangxi, W Guizhou, Hainan, Jiangxi [N Vietnam].
Gao Lianming (pers. comm.) notes that a wider circumscription of Rhododendron westlandii is used here than in FRPS (57(2): 355. 1994, where it was treated as a synonym of R. moulmainense). Recent herbarium studies indicate that the calyx characters that have been used to separate R. westlandii from R. kaliense and R. linearicupulare are very variable and cannot be reliably used to delimit species.
