120 THE CAYUGA FLORA. 



[C. squarrosa, L., in Sartwell's Cat of 1844.] 



1 154. C. retrorsa, Schw. (H. and C.) 

 Meadows and the lake shore ; frequent. June-July. 



1 155. C. retrorsa, Schw., var. Hartii., Carey, (for full description, see 

 Paine's Cat., p. 163.) Ludlowville, (J/r. Lord in Paine's Cat.) 

 Ithaca Marsh. Ellis Hollow Swamp. Slenderer than the type, the 

 lowest spikes loug-peduucled, perigynia few-nerved and akenes not 

 as papillose as in the type. 



1 156. C. utriculata, Boott, (C.) 

 The typical form, in the borders of deep cold swamps, is rare here; 



Summit Marsh. Meadows south of Michigan Hollow Swamp, 

 as forma composita (local.) These have elliptical or oblong 

 perigynia, 7-9 mm. long, with short teeth, as figured in Boott, II- 

 lustr., tab. 39. The spikes of the latter are branched below in a 

 proliferous manner. The common form, occurring in the larger 

 marshes and along our ponds and lakes, has much smaller, nearly 

 ovate perigynia. Its extreme is the next variety. 



1 157. C. utriculata, Boott, var. minor, Sartwell. 



Ludlowville, (H B. Lord, in Paine^s Cat., p. 164, and in Cornell 

 Univ. Herb.) Canoga. Round Marsh. 



115S. C. ampullacea, Good. (H-) 



Specimens from Locke Pond, and more pronounced ones from 

 the Marl Ponds, must be referred here, although they are not typi- 

 cal. The few spikes, slender and mosly smooth culm, canaliculate 

 leaves, and scarcely hispid scale, show the approximation to that 

 species, and yet suggest certain characters of C. utriculata. 



Ii58 a . C. ampullacea, Good., var. sparsiflora, Dew., "Junius," [Herb. 

 Sartwell.)
