San Francisco (Bolander) ; San Diego County, Palmer. Common in Europe and the Mediter- 

 ranean region ; also found in Chili. This rather handsome grass is very common on the coast 

 and, according to Mr. Bolander, late in the season covers the dry hills everywhere. Of no recog- 

 nized agricultural value ; animals on the continent of Europe are said to eat it. 



2O. CINNA, Linn. WOOD REED-GRASS. 



Panicle open, flexuose with spreading rays, or narrow with rigid erect branches. 

 Spikelets 1-flowered, more or less flattened. Glumes lanceolate, acute, 1 -nerved, 

 the lower shorter, the upper equalling or slightly longer than the floret. Floret with 

 a manifest callus, or even stipitate within the glumes. Palets similar in texture to 

 the glumes, the lower 3-nerved, acute and awnless, or bearing a short awn or seta 

 just below the apex, the upper indistinctly 2-nerved, or with the nerves confluent 

 and apparently 1-nerved, slightly shorter. Scales 2, very short. Stamens 1 to 3. 

 Ovary oblong, smooth : styles 2, elongated ; stigmas plumose. Grain linear-oblong, 

 free. 



A small genus of perennials, formerly including several species now placed in Muhlenbergia. 



1. C. arundinacea, Linn., var. pendula, Gray. Culm 2 to 6 feet high, 

 smooth, with conspicuous brownish nodes : leaves flat, lanceolate, 4 to 8 lines broad, 

 rough on both sides and margins ; ligules conspicuous, 2 to 4 lines long ; sheaths 

 shorter than the iriternodes, smooth or slightly roughened : panicle 8 to 12 inches 

 long, drooping at apex, the capillary rays clustered, distant, flexuose, very unequal, 

 the longer flower-bearing above the middle, very scabrous : spikelets about 1 ^ lines 

 long, pale green, strongly flattened : glumes very acute, pubescent, ciliate-hispid on 

 the keel : lower palet minutely hairy, especially on the nerves, the terminal mucro 

 distinct or quite wanting in the same specimen ; stipe very distinct with sometimes 

 a minute rudiment : stamen solitary, opposite the upper palet. Manual, 2 ed. 545.

Big Tree Grove (Bolander) ; Oregon and Washington Territory (Lyall, Hall) ; and north to 

 Sitka. Eastward it is found in the northern border States and in the mountains southward, and 

 it also belongs to northern Europe and Japan. The rarer typical form, ranging from Canada to 

 Louisiana, has not thus far been detected within the State. It has a much denser and narrower 

 panicle, longer spikelets (sometimes 3 lines), and is often tinged with purple. The type and 

 variety have a rather pleasant scent, but neither appears to be sought after by cattle. 



2. C. macroura, Kunth. Culm 3 or 4 feet high, erect and rigid, smooth or 

 slightly pubescent below the nodes, clothed below with broken and withered sheaths : 

 leaves narrow, convolute and attenuate at apex, rough-pubescent, the lower 3 to 4 

 and the uppermost 1 to 2 inches long, all very rigid ; ligule 2 or 3 lines long ; sheaths 

 much longer than the internodes, loose, rough : panicle 1 or 2 feet long, erect, very 

 narrow, dense and tapering above, loose and interrupted below, the base sometimes 

 included ; rays fascicled, very unequal, the longer (1 to 4 inches long) flower-bearing 

 above, the shorter for their whole length ; all, with the common axis, more or less 

 roughened : spikelets 1 to 2 lines long, scarcely compressed, minutely scabrous- 

 pubescent and on rough pedicels about their own length : glumes acute at apex or 

 blunt with a minute point, the lower somewhat longer and indistinctly 3-nerved : 

 floret usually somewhat exceeding the glumes, with a brief and minutely hairy callus ; 

 palets very delicate in texture, the lower minutely pubescent, more or less acute, 

 3-nerved, broad and involving the very thin distinctly 2-nerved upper one, which is 

 about the same length : stamens 3, Avith linear anthers. Gram. i. 67 ; Trin. Agrost. ii.
