SOME UNDESCRIBED VARIETIES AND HYBRIDS OF 
CAREX. 
M. L. FERNALD. 
IN the course of recent studies of New England Carices five 
forms have been examined which differ so markedly from the described 
species as to merit special recognition. 
Carex vESTITA, Willd., var Kennedyi. Pistillate spikes solitary or, 
if 2, closely approximate, the upper sometimes androgynous; stami- 
nate spike very short, overtopped by the pistillate. Near Silver 
Lake, Wilmington, Massachusetts, June 11, 1899 (G. G. Kennedy) 
A remarkable plant, on a casual examination seeming to have only 
pistillate spikes, and thus appearing very unlike typical C. vestita with 
its long, clavate, staminate spike. 
C. maritima, Müll., var. erectiuscula. Spikes short, 1.25 to 1.75 
cm. long, short-peduncled or subsessile, erect, not drooping, scattered 
or approximate : scales with shorter less conspicuous tips than in the 
species: perigynia smaller than in the ordinary American form, barely 
3 mm. long. Cushing, Maine, July 10, 1888 (F. S. Collins in herb. 
C. W. Swan). An extreme form of the species parallel with C. crinita, 
vars. minor and simulans. 
C. lupulina x bullata. Coarse as C. Zupu/ina: pistillate spikes 
subtended by broad elongated bracts, solitary or 2, remote, sessile or 
short-peduncled, 3 to 5 cm. long, 3 cm. broad, mostly staminate at 
tip: perigynia firm as in C. ?u//afa, but large and dull as in C. Zupu- 
lina: principal staminate inflorescence peduncled; the peduncle 
about half as long as in C. bullata; the spikes numerous, as large as 
in C. lupulina. About small ponds in woods, Medford, Massachu- 
setts, July 31, 1870 (Wm. Boott). 
C. retrorsa x utriculata. Spikes and perigynia as in C. wtric- 
ulata, but the perigynia mostly retrorse as in C. retrorsa. Connec- 
ticut, probably near Hartford (C. Wright in herb. C. W. Swan). 
C. virescensx arctata. Slender and tall, 6 to 8 dm. high: 
leaves long and comparatively narrow (broadest 3 or 4 mm. wide), 
pubescent, especially on the sheaths: spikes slender, 2.5 to 5 cm. long, 
2 to 2.5 mm. thick, mostly peduncled, ascending or spreading : perigynia 
as in C. arctata, minutely puberulent or glabrous. Wooded banks with 
both parents, Surry, New Hampshire, July 23, 1899 (M. L. Fernald 
in herb. Alstead School Nat. Hist. No. 242). Beautifully combin-
