achenes. Pappus of 5 to 10 paleae or none. (Named for a Greek girl 
who attended the lectures of Plato in the garb of a man.) 
1. L. glabrata Lindl. Usually branching above the base, 2.6 to 3.8 dm. 
high; leaves linear and entire or the upper pair broadly lanceolate and 
toothed, connate and sheath-like at base; peduncles elongated; pappus 
present.—Borders of salt marshes. 
22. MONOLOPIA DC. 
White-woolly annuals with alternate sessile entire or low-denticulate 
leaves and large peduncled heads of golden yellow flowers. Involucre 
hemispherical. Receptacle conical, naked. Rays with the ligule 3 or 4- 
toothed at apex and bearing at base and opposite the ligule an oblong or

(Greek mono, single, and lopos, husk, on account of the bracts of the 
involucre in one series.)
