I have been able to see a specimen of Herb. Falconer distributed from Kew in 

 1869. The flowers of this specimen agree fully with those of Wilson's. Wight's 

 figure shows a flower with glabrous corolla-lobes wliich are always hairj^ within in 

 the specimens before me, with the exception of those of a specimen in Herb. Gray, 

 from Sikkim " Regio temp. alt. 6000 ped.," J. D. Hooker. Forrest has collected 

 a species with glabrous corolla-segments near Yunnan-fu, and it was described 

 by Schlechter (in Not. Bot. Card. Edinburgh, VIII. 15 [PI. Chin. Forrest.] [1913]), 

 as P. Forrestii, which I know only from the description.
