BALFOUR—NEW SPECIES OF RHODODENDRON. 263 
Cephalanthum series, and yet it is not so loose and spongy as is 
typical there. The broad disks of the scales are very beautifully 
seen in this new species. The colour of the indumentum is 
darker (on the way to rufescent) than in any other species of the 
series. The flowers are bright yellow as they are in Rh. gym- 
nomiscum, Balf. f. et Ward, Rh. nwatense, Balf. f. et Ward and 
in Rh. Sargentianum, Rehder et Wilson of the series. The 
large leathery bracts with broad soft scales on the back are char- 
acteristic, and it is one of the species that has a puberulous rhachis 
to the inflorescence and lepidote short pedicels. The calyx is 
distinctive from most species of the series the lobes having a 
lepidote margin. The stamens have glabrous filaments, and the 
style is shorter than the ovary. 
I hope Mr. Farrer has introduced to cultivation this beautiful 
little species.
