Damp woods at Fong Kong Tze near Foochow, Hongkong Herb. 3711. 
Wet roeks at Tam Chuk Hang near Foochow, Hongkong. Herb. 3718, 
Although the leaves of the Fong "Kong Tze plants have rounded lobes, while 
those of the specimens from Tam Chuk Hang are acute, giving the two forms 
а somewhat different facies, the divergence does not appear sufficient for the 
foundation of two species or even of two varieties. P. cordata, Brown, is 
allied. The trivial name commemorates the service to Chinese botany of 
Mr. Х. E. Brown, the auther of the account of the Aroids in Hemsley and 
Forbes's ** Enumeration ” (Journ. Linn. Soc., Dot. xxxvi. (1903) 173-188).

The inflorescence of this remarkable sedge, which in other respects 
approaches С. Harlandi, resembles the tuft that would be left if the 
flowering stem of one of the scapose sedges were drawn between the fingers 
so as to remove the bracts and spikes.
