 var. Sartwell, Exsicc. No. 49. C fcenea, Boott, 111. Car. 3, p. 118, tab. 

 377. Cfcenea, var. ? sahdonum, Gray, Man. ed. 5. C adusta, Carey 

 in Gray, Man. ed. 1. non. Boott. C. festucacea, Sartwell, Exsicc. No. 44,

 Hampshire, Isle of Shoals, Canby. Rhode Island, on racks and beaches, 

 Narragansett Bay. Massachusetts, Ipswich, in sand, Oakes. New York, 

 Sartwell. Cape Henlopen, Delaware, Canby. June, July. — The dif- 

 ferent color, the alternate spikelets, nutant spikes (in this resembling 

 C. straminea, var. apcrta, Boott), and involute leaves, surely separate 

 this from C. foenea. The fruit matures early ; that of G.fcenea ripens 

 a month or more later. 



Carex senta, Boott, n. sp. : " Mr. Brewer has recently found in 

 California specimens which, in habit, closely resemble C. angustata, 

 Boott, but differs in the perigynum being conspicuously toothed at the 

 margin, and the vagina of the leaves externally scabrous, and in the 

 larger size of the perigynum." Boott, 111. Car. 4, p. 174. It is 

 Brewer's No. 350, which was collected in a canon of the Santa Inez 

 Mountains, California. 



Carex bifida, Boott, n. sp. " With the habit of G. Buxhaumii WahL 

 differs in the bifid orifice of the perigynum, which is not granulated ; 

 the leaves are broader, and scales shorter." Boott, MSS. April, 1863. 

 It is Brewer's No. 574, of Salinos Valley, south of Monterey, and Bo- 

 lander's 6476 from Red Mountain, Humboldt County. 



Carex gynodynama, Olney, n. sp. : spicis 4-5 cylindricis erectis 

 ferrugineis, terminali masculi apiee foeminea, i-eliquis foemineis, suprema 

 masculam longe superante, infiraa reraota longe vaginata pedunculata ; 

 bracteis involutis ciliatis, infima culmo subajquali vel breviore ; stig- 

 matibus 3 ; perigyniis ellipticis rostratis bifidis olivaceis basi leviter 

 nervatis (apice purpureo pilis longis albis vestito, basi glabra) squama

 fornia, near Mendocino City, Bolauder, 4700. Caespitose : culms
