 mi. C. platyphylla, Care}'. (Dr. Wright in C.)

1 1 12. C. platyphylla, Carey, var. ■. 



In the nook, opposite the Beechwoods, Six Mile Cr., 1883, (O. E. 

 Pearce.) Elmwood Glen, Cayuga L. It differs from the type in 

 leaves broader, (3 cm.) and longer than the culm; and pistillate 

 spikes mostly with 6 flowers instead of 3 or 4 ; Boott says there 

 are rarely 7 flowers in the type. 



11 13. C. retrocurva, Dew. 



Beech woods and elsewhere ; abundant. June 15-July 15. 



Variable in width of leaves and length of bracts. Forms with 

 green leaves 4-6 mm. broad, in Six Mile Cr., Taughannock and 

 Paine's Cr. These have, however, the sterile flowers at the base of 

 the pistillate spikes, characteristic of true C. retrocurva. A form 

 was found near Ovid, with broad leaves, (8-14 mm.) and large 

 perigynia, suggesting C. platyphylla, but the peduncles were long 

 and slender.
