C. (Sect. Tumidae, Ktikenthal) Hwangii n. s. 



Rhizome Leaves longer than stem; 9 rara broad, sub- 



flaccid. Spikes 4 (always ?), terminal ^ , linear, 7 cm. long, 

 lateral ones cylindrical, dense flowered, 5-6 cm. long, some- 

 what approaching to the terminal, subsessiile, patent. Bracts 

 foliaceous, surpassing inflorescence, very shortly sheathing. 

 Squama? ^ ovate-oblong, subacumlnate, aristate with short 

 scabrous arista. Utricle a little longer than the squama, 3.5 

 mm. long (inch beak), divaricate, smooth, subinflate, trigonous, 

 greenish, indistinctly multi-nerved, contracted at base, narrowed 

 into a beak of median length. Nut trigonous, with concave 

 surfaces, smooth, castaneous. Style subincrassate at base, 

 branches 3. 



Kiang-su : Shang-hai. 



The species is closely allied to C olivacea Boott, but diff^ers 

 from it in the light colored spikes, and in the form of g 

 squama. The spikes are greenish in the present species, but 

 not olivaceous. The female squamae are ovate oblong, and 

 shortly aristate, arista being 1 mm. long ; but in C. oHvacea 

 they are oblong lanceolate and long aristate, arista baing 3 

 mm. long. 



I name the species in honor of Hwang-yi-jen who collected it.
