 base of the bractlet, exserted more than y 2 the length of the bracts. — (C. 

 sylvatica, Thurb. in Bot. Cal., not of DeCandolle. Description adapted from that 

 of Thurber, in the absence of specimens. Reported as having been collected 

 by Bolander in the "Redwoods," but the actual locality is not stated; per- 

 haps not within our limits, but to be looked for.) 



2. C. aleutica Hong. Aleutian Reed-grass. Stems stout, erect, 2 to 5 ft. 

 high; sheaths minutely scabrid ; blades 6 to 12 in. long, 3 to 5 lines wide, 

 scabrid on both surfaces, margins scabrous; panicle 6 to 10 in. long, y 2 to l 1 /^ 

 in. broad, loosely contracted and somewhat interrupted, somewhat drooping 

 above; branches erect, some at each node spikelet-bearing from the base; 

 spikelets acute; lower bract 1% to 3VL> lines long, glabrous except the scabrid 

 keel; upper rather shorter: bractlet 2% to 3 lines long; awn from near the 

 middle of the bractlet and barely equaling it, usually strongly geniculate; 

 anthers 1 to iy 2 lines long. 



Along the seashore in rocky or marshy places, from Pt. Reyes northward. 

 June-July. A tall coarse species, forming large tufts. 



3. C. angusta Kearney. Narrow Reed-grass. Perennial; stems few, 

 slender, 2 1 /? to 3% ft. high; ligule about 2 lines long, apex broad, truncate 

 or rounded; blades not filiform, all strongly involute, at least above; panicle 

 spikelike, narrow and dense, strict, 4 1 /£> to 7 in. long, sometimes interrupted 

 below ; branches short, appressed, the lower in threes ; spikelets densely crowded, 

 about 3 lines long, strongly compressed; bracts subequal, rather- sharply 

 killed; awn from near the base of the bractlet, and shorter than or not 

 much exceeding the bracts, iy 2 lines long, stout; anthers \ x / 2 lines long. 



The type, which appears to be the only specimen so far known, is from Santa 

 ( Iruz. 



4. C. subflexuosa Kearney. Flexuous Reed-grass. Stems tufted, slender, 

 erect, 2 to 3 ft. high; sheaths minutely scabrid; ligule 1 to 2 lines long, apex 

 slightly truncate; blades strongly involute, but not filiform; panicle 4 to (i in. 

 long, oblong-lanceolate, narrow and dense, almost spiciform, often interrupted 

 or lohed below, usually somewhat flexuous, brownish-purple ; branches erect, in 

 fours or sixes below, the longest about 2 in.; spikelets crowded, 2 to 2% 

 lines long, strongly compressed; bracts subequal, about 2U> lines long, sharply 

 keeled, glabrous except the scabrid keel; bractlet and palea minutely o- toot lied; 

 awn from a little above the base of the bractlet, about equaling the bracts, 



stout ; anthers 1 line long. 



Oakland Hills, Bolander, no. 2274; does not appear to have been re-collected. 



It resembles ( '. aleutica, bul is said to be at once distinguishable by the 

 short and narrow involute Leaves and by the position of the awn.

 from a scaly, st oloni ferous rootstock: stems 2 to 2% ft. high, stout, erect from 

 a decumbent base, very Leafy, densely clothed with the old, dry sheaths; the 



lowest sheaths bearded at the junction with the blade; ligule 1 ' L . lines long, 

 serrate; blade about 1 line wide. Hat or becoming involute, minutely scabrid. up
