 Scleria reflexa HBK. Nov. Gen. 1; 232. 1815.

 dad; Jamaica; tropical continental America. 



My examination of the type specimen of Schoenus secans L., 

 in the herbarium of the British Museum of Natural History, 

 some years ago, showed that it was the same as Scleria reflexa 

 HBK., and not the same as Scleria Flagellum-nigroriim Berg. 



4. Scleria catalinae sp. now 



Perennial by thick rootstocks; culm stout, sharply 3-angled, 

 roughish on the angles, glabrous, about 1.3 m. high. Leaves 

 glabrous, slightly roughish-margined, 3-5 dm. long, 1-2.3 cm. 

 wide, 3-nerved, attenuate-acuminate, the ligule triangular-ovate 

 to triangular-lanceolate, acute or acuminate, many-striate, nar- 

 rowly callous-margined, 2 cm. long or less; panicle about 5 dm. 

 long, of few, distant, slender branches, the staminate and pistillate 

 spikelets intermixed; staminate spikelets oblong, 3-4 mm. long; 

 achene ovoid, purplish, smooth, shining, acute, 2 mm. long, the 

 style-base persistent ; hypogynium obconic, I mm. long, glabrous, 

 its base rounded, its 3 rounded lobes appressed. 



Santa Catalina, Pinar del Rio {Van Hermann 3272). 



By its very large ligule related to S. arundinacea Kunth, but 

 the achene and inflorescence are quite different, resembling those 

 of S. cubensis Boeckl.
