70. MONOLOPIA, I)( . 

 Head many-flowered, with 8 to lU pistillate rays; some of the disk-flowers often 

 sterile. Involucre a single (or in M. minor somewhat double) series of tliiu-herba- 

 ceous flat equal scales, united at base or into a hemispherical cup. Receptacle more 

 or less conical, naked. Eays broad, 2 - 4-toothed or lobed at the summit, some- 

 times with an opposite small lobe or appendage at the base of the ligule': disk- 

 corollas with a rather slender tube and a dilated-funnelform or campanulate throat 

 or limb, the ovate lobes more or less bearded. Anthers tipped with ovate append- 

 ages. Style-branches truncate-obtuse. Akenes obovate or oblong, quadrangular- 

 compressed or flatter, the outer ones obcompressed or triangular" with terminal 

 areola small, whoUy destitute of pappus. — Californian floccose- woolly or cottony 

 annuals : with mostly alternate or sometimes mainly opposite entire or pinnately 

 parted leaves, and terminal slender-peduncled heads of yellow flowers. 



The type of the genus, our second section, is M. major. Except for this species it were better 

 to include the hrst section in Bahia. The best cliaracter of the genus is furnished bv tlie 

 broader and flattened akenes, supplemented by the constant al)seuce of pappus —not iii tlie 

 gamophyllous involucre, which varies in the original species, and nearly fails in one form of it. 



§ 1. Low, a span high: leaves {alternate) not clasping, sometimes petioled and 2nn- 

 natifid: rays destitute of the little appendage, barely 'I -2, toothed at the apex 

 — Pseudo-Bahia, Gray. 



1. M. bahicBfolia, Benth. Slender, whitish with close cottony wool : leaves 

 Imear-oblanceolate or spatulate and entire, or some of them obtusely S-lobed (about 

 half an inch long) : scales of the involucre united about to the middle : akenes 

 hairy, esi.ecially towards the rounded summit. — PI. Hartw. 317. 



Var. pinnatifida, Gray. Leaves (sometimes an inch long) nearly all once or 

 even twice pinnately parted into oblong or linear lobes. — Monolopia Heermanni, 

 JJurand. 



Hillsides &c.. Valley of the Sacramento, Hartivcc,. The variety, Calaveras Co., Dr. Hcermann. 

 Also near Auburn, Placer Co. Bolandcr. Involucre broadly campanulate or hemispherical, 2* 

 lines high. Rays about 8, oval or oblong, 2 or 3 lines long. Receptacle, at least in the variety, 

 narrowly conical. Akenes a line long, rather broad and flatfish, with small areola. 



2. M. minor, DC. Loosely very woolly, mostly pinnately 3-5-parted into 

 linear divisions : scales of the involucre united only below the middle, rather obvi- 

 ously m two series : ovary glabrous. — Hook. Ic. PI. t. 343. 



California, the locality unknown, collected only by Douglas. Head hemispherical : receptacle 

 apparently little elevated. Ovaries obovate-oblong. Lobes of the corolla bearded. 



§ 2. Larger: leaves entire or somewhat toothed, sessile and partly clasping: rays 

 dilated, coarsely 3 - i-toothed or lohed at the summit, the base on the opposite 

 side of the style a^ypendaged loith a small and rounded denticulate lobe. — 

 True Monolopia. 



3. M. major, DC. "White or whitish with floccose wool, sometimes becoming 

 glabrate and green, a span to 2 feet high : leaves varying from linear to broailly 

 lanceolate or the upper lanceolate-oblong, entire or coarsely and unequally repaud- 

 serrate : scales of the broadly campanulate or hemispherical involucre united to or 

 above the middle : akenes glabrous or very minutely hirsute-puberuleut. — Hook.
