Rhododendron purdomii

R. purdomii (Pontica eller Fortunia ) Langsomt voksende krybende stedsegrøn dværgbusk som når en højde på 20 cm efter 10 år. Blomster hvide med nogle få røde pletter. Vildtvoksende i Gansu bla. på Taibai Shan. Nogle kloner har 7 kronblade med kortere lapper som peger på slægtskab med Fortunea andre kloner ligner mere Pontica, så der er måske en uændret stamfader til disse to subsektioner Hans Eiberg
Collected from Taibai Shan in China. ARS 461/1995 (from Xian Botanical Garden -> Holden Arboreum -> ARS 461/1995). As a seed plant it looked like a R. aureum, which is located in Pontica subsection (HE. 2008). The crown is also somewhat deeply divided as is characteristic of the species in subsec. Pontica, but not in subsec. Fortunea, Taliensa and Selensia. Seeds booth is some candelabra shaped like at R. aureum (2009) H. Eiberg
R. purdomii grown from cw seed by the late Peter Wharton. Jens Nielsen saw it when he was here and said it matched the ones he saw and collected in China (Szechuan or Gansu???). John Weagle
