TWO NEW SOUTHERN SPECIES OF COREOPSIS 



Coreopsis falcata n. sp. 



A glabrous perennial herb 8-i2 dm high. Stem stout, erect, 

 hollow, corymbosely-branched near the summit, round, striate, 

 leafy to the branches : radical and lower leaves scythe-shaped, 

 2-3 dm long including the petioles, i-2 cm broad, terminating in a 

 rather blunt point, entire or with one or more narrow, ascending 

 lobes, gradually narrowed below into a winged petiole which is 

 enlarged at the base and forms a clasping sheath ; upper stem 

 leaves narrower, sessile by a clasping base, usually with 2-4 very 

 narrow lateral lobes, the terminal portion of the blade long and 

 curved ; leaves of the branches much reduced in size or bract-like : 

 heads several, 3~5 cm broad including the rays : outer involucral 

 bracts lanceolate, 5-7 mm long, the inner about one-third longer 

 than the outer, oblong-elliptic to broadly ovate, thin, marked with 

 purple lines : chaff of the receptacle linear, acute, tipped with red : 

 rays orange-yellow, three-lobed, the middle lobe the largest, 

 rounded or sometimes notched at the apex : ovary minutely hispid 

 on the margins : pappus a pair of straight awns : ripe achenes not 

 seen. 



The species above proposed is evidently related to C. longifolia Small 72 and 

 C. gladiata Walt. 73 The longer outer involucral bracts of C. falcata, together 

 with its more robust habit and peculiar leaves, present characters which serve to 

 distinguish it from both species mentioned. 



The original specimens were collected in shallow water near Pembroke, N. C, 

 June, 1901. The type material is preserved in the Biltmore Herbarium. 



Coreopsis stenophylla n. sp. 



A glabrous, annual or short-lived perennial herb 3~4 dm high. 

 Stem stiff and wiry, usually several from the same base, striate, 

 leafy throughout : leaves firm, erect or ascending, opposite, nar- 

 rowly linear to filiform, 2-6 cm long, the lower sometimes 2 mm wide 

 and narrowed into slender petioles; the upper i mm or less wide, 

 often with one or two filiform, lateral segments : heads several,
