 leaves regularly disposed along the stem or branches (the basal ones not seen); blades 

 cuneate to oblong-cuneate, 1.5-2.5 cm. long, obtuse, densely pubescent but not as pale as 

 the stem except the margins, partly clasping : heads few, terminating somewhat glandular 

 peduncles : involucres 6-8 mm. high ; bracts linear-lanceolate to linear, firm, glandular, 

 merely acute : ray -flowers with ligules about 1 cm. long. 



In sandy soil, near Braidentown, Florida. Fall. 



17. Chrysopsis latisquama Pollard. Foliage woolly below, glandular above. 

 Stems 3-7 dm. tall, corymbose above, the branches often elongated : basal and lower stem-

 blades oblong or nearly so, serrate : involucres 7-8 mm. high ; bracts mostly broadest 

 above the middle, not woolly, glandular, deep green, the outer rather foliaceous, usually 

 acute : ray-flowers with ligules about 1 cm. long. 



In low pine lands, peninsular Florida. Spring to fall. 



18. Chrysopsis decumbeiis Chapm. Foliage densely cobwebby. Stems decum- 

 bent, 6-12 dm. long, corymbose above : basal leaves in dense rosettes ; blades spatulate 

 to linear-spatulate, 4-8 cm. long, sparingly toothed : stem-leaves numerous ; blades oblong 

 to linear-oblong, 1-2 cm. long, obtuse, entire : heads showy, in loose corymbs : involucres 

 8-10 mm. high; bracts linear-lanceolate to linear, glandular-pubescent, acute or acuminate;
