Beskrivelse

Fundet i Tibet på ny vej mellem Liijang og Lhasa – ligner en R. burjaticum, der vokser i Øst Sibirien ved Sayan / Sajal bjergene som ligger op til Buryatia (in Eastern Sayan, Khamar-Daban range) i Irkutsk regionen nord for Tibet og er kompakt voksende. R. bulu har en flad tragt så den er udelukket. R. burjaticum er den mest sandsynlige. Denne plante har blade på ca. 2 cm. Er måske en hybrid mellem R. adamsii og R. parvifolium, idet planten vokser mellem disse to arter.
