360 PROCEEDINGS OF THE AMERICAN ACADEMY 



foliis argute dentatis oblongis vel summis ovatis imie basi breviter at- 

 tenuata subspathulatis ; involucri squamis 2 — 3-seriatis lanceolatis ; 

 ligulis circiter 30 parvis rubellis ; pappi paleis oblongis, 2 tubi vil- 

 losissirai corolla? dimidium adasquantibus, 2 alternis brevioribus. — 

 Yosemite Valley ; only one specimen seen, Bolander. — Related to 

 tbe preceding ; but the heads (four or five and racemose at the sum- 

 mit of the stem) large ; rays much more numerous and smaller, the 

 slender ligule only 3 lines long and reddish purple, tube of the corolla 

 conspicuously villous, and leaves with sharp salient teeth, the larger 

 almost 3 inches long. 



Layia pentacileta, Gray in Bot. Whipp. p. 108, t. 16. Speci- 

 mens collected by Mr. Bolander in 1865, at Forest Hill, mixed with 

 L. yaillardioid.es (distinguishable only by the pappus), have in some 

 cases the pappus reduced to two or three seta? or no pappus at all. It 

 is then still readily distinguishable from the following by the copious 

 stipitate glands, uniformly and deeper colored rays, naked receptacle, 

 and scales of the involucre loosely hirsute, without the short strigose 

 bristles of 



Layia (Oxyura) chrysanthemoides. Oxyura ckrysanthemoides 

 and Hartmannia ciliata, DC. This is seldom collected ; but it occurs 

 in Mr. Bolander's and Dr. Kellogsfs recent collections. 



Calycadenia mollis ; virgata, pube brevi molli (nusquam his- 

 pida vix villosa) cinerea ; glomerulis axillaribus dissitis breviter pe- 

 dunculatis ; ligulis 2-3 tubo brevi, lobis rotundatis requalibus ; floribus 

 disci 4-6; paleis receptaculi truneato-obtusis subapiculatis eglandu- 

 losis ; pappi paleis circiter 5 subulato-aristiformibus scabris corolla 

 paullo brevioribus nunc 1-2 additis brevibus oblongis muticis. — At 

 Clark's, Mariposa Co., Bolander. — About a foot and a half high. 

 Principal cauline leaves 1 or 2 inches long, those of the axillary 

 fascicles and the floral ones or bracts more or less glanduliferous. 

 Fertile achenia rugose ; sterile ones a little hairy on the angles. 



Anisocarpus Bolanderi : caule elato (3 - 4-pedali) ; foliis ple- 

 rumque integerrimis, inferioribus linearibus elongatis (6-10-polIicaribus 

 lin. 4 - 6-latis), superioribus brevibus (1 - 3-pollicaribus) e basi lata 

 lanceolatis; capitulis majoribus ; ligulis 15-20; fl. disci paleis pappi 

 5-6 angustissime subulato-linearibus plumoso-fimbriatis corollam sub- 

 requantibus. — Mariposa Big-tree Grove, Bolander. Heads twice 

 the size of those of A. madioides, and with about twice as many flow- 

 ers, the plant similarly hirsute and viscous. Ovaries of the disk-
