Beskrivelse
R. lepidostylum (Trichoclada) (- 18 °C). Berømt for sin meget blå bladvækst, og berygtet for sin ustabile opførsel. Denne plante danner en lav og bred silhuet. Bladene er små og tæt skællede, meget aromatiske og med en usædvanlig farve, nærmest voksagtig dueblå. Blomsterne er små, bleggule og kommer i maj-jun., men er oftest mere eller mindre skjult af bladvæksten. Vanskelig at holde i perfekt stand. SV Yunnan 3.000-3600 m.
