102 PROCEEDINGS OF THE CALIFORNIA 



Plumes unequal, oblong, tapering abruptly into a blunt point, scabrous, dis-' 

 tinctly nerved, broadly hyaline margined (lower 3 to 5, upper T-nerved). 



Palets unequal ; lower oblong (0.43 inch long) distinctly 7-nerved, (the three 

 central excurrent, the others evanescent) scabrous and tuberculate, broadly 

 hyaline margined toward the apex ; lower about one-third shorter, pyriform, 

 obtuse, coriaceous, tuberculate, ciliate. Anthers three, (i^ of an inch long). 



Root tuberous; fibres tomentose. Culms rarely ctespitose, 3 to 6 feet high, 

 erect, terete, canaliculate, smooth and leafy. Sheaths scabrous, the lower longer 

 and the upper shorter than their internodes. Ligules exserted, lacerated. 

 Leaves lanceolate, one-eighth of an inch wide, 7 to 10 inches long, scabrous. 



Panicle oblong, simple, 6 to 10 inches long, interrupted ; branchlets very un- 

 equal, generally in fours, of which one is much longer than the rest, usually 

 spreading and many flowered, ■while the others are unequally short and one or 

 few flowered ; the rachis and branchlets angular and retrorsely scabrous. 



Quite common in dry soil, in the upper part of Yosemite Valley, 4,000 feet 

 alt. July, 185C. (My number 6,121 of Catalogue, 1867.) 



3. Me lie a Harfordii Bol. 



Root perennial, fibrous ; fibres tomentose. Culms csespitose, terete, lower 

 internodes declining, then erect, 3 to 6 feet high, glaucous, generally smooth, but 

 sometimes • scabrous, leafy, (4 to 7). Sheaths smooth or .scabrous, lower ones 

 longer, and the upper ones shorter than their internodes. Ligules short and 

 obtuse. Leaves lanceolate, 6 to 14 inches long and ^4 of an inch wide, on the 

 inside, as well as on the margins, retrorsely scabrous. 



Panicle 6 to 12 inches long, %-% inch wide, claviform, interrupted especially 

 below, but more dense and compact towards the apex, branchlets in series of 

 twos and threes, short, unequal and closely appressed, single or few flowered. 

 Rachis and branchlets scabrous. Spikelets oblong, cylindrical, ^o to ^8 'of 

 an inch long, 5 to 8-flowered, uppermost abortive. Plumes unequal, obtuse, 

 membranaceous, distinctly nerved, lower unequal, upper nearly equally, .5-nerved. 

 Palets oblong ; lower coriaceous, but slightly scarious margined, 5 to 7-nerved. 

 The middle nerve is generally extended into a short scabrous awn, obtuse or 

 refuse, scabrous, pubescent especially on the margins ; lower palet j^ shorter, 

 obtuse or retuse, ciliate. 



Wooded hillsides, Santa Cruz road, near Lexington, June, 1865. (My num- 

 ber .53 of small sets of grasses.) Redwood, on the upper Mattole River, June, 

 1867. (Xo. 6,464.) Shady debris, Yosemite Valley, June, 1866. Bear Val- 

 ley, Nevada County, (4,.500 feet alt.) on rocks and debris, June, 1869. 



It gives me great pleasure to name this beautiful species in honor of W. Gr. 

 W. Harford, a very zealous co-laborer in natural history for several years. 

 Although the gentleman devotes most of his time to conchology, yet he has 

 constantly embraced every opportunity to collect largely botanical specimens. 

 He explored some of our northwestern counties, visited the coast south of San 

 Francisco, and the Sierras in Mariposa County. Last summer he also made a 

 large collection of botanical specimens in Oregon, along the Columbia River.
