A PRELIMINARY SYNOPSIS OF THE SOUTHERN 
CALIFORNIA CYPERACEAE. VII.* 
BynS) Bakarisht 
§. CAREX Linn. Sp. Pl. 972. Sedge. 
Perennial herbs, with mostly 3-angled leafy culms. 
Spikes simple or aggregated, monoecious, dioecious, or 
androgenous, each subtended by a leafy or seale-like involucral 
leaf, or bract, or rarely bractless. Flowers solitary in the axils 
of scales; the staminate of 3 stamens; the pistillate of a single 
pistil. Perianth wanting. Styles with 2-3 stigmas. Achenes 
3-angled lenticular, or plano-convex, completely enclosed in a 
sac-like bractlet, called the perigynium. 
A genus of over 1,000 species; of wide distribution, but 
most abundant in temperate climates. In Southern California 
they are most largely represented in the higher mountains, 
often forming the prevailing herbage of meadows. Most of our 
species are hydrophytic or mesophytic, but a few are xero- 
phytic. 
Two subgenera are recognized: 
Staminate and pistillate flowers in separate, mostly sim- 
ple and elongated spikes. I. Eucaryx. 
_ Staminate and pistillate flowers in the same sessile, mostly 
short and aggregated spikes. II. Vignea. 
Subgenus I. HUCAREX, Coss, Fl. Paris, 744. 
Staminate flowers in one or more terminal linear or clavate 
spikes. Pistillate flowers. in inferior, simple, pedunculate or 
sessile spikes. Or the spike solitary and staminate at summit or 
base, or rarely dioecious. Stigmas mostly 3, and achenes tri- 
gonous or triquetrous; or stigmas 2, and achenes lenticular. 
One or more of the uppermost pistillate spikes is often 
staminate at summit, or rarely at base, and one or more of 
the staminate spikes may be pistillate at base or summit. 
KEY TO EUCARYX. 
I. Staminate flowers in one or more terminal spikes; pistil- 
late flowers in several inferior sessile or pedunculate spikes. 
Perigynia attenuate to a beak one-third as long as the body, or 
longer.
