164 Small : The flora of peninsular Florida 



appressed-pubescent: leaves opposite; blades ovate in outline, i- 

 4 cm. long, more or less distinctly hastate-lobed and irregularly 

 toothed, rough-pubescent, short-petioled : heads long-peduncled : 

 involucres not foliaceous; bracts ovate to oblong-ovate, not sur- 

 passing the disk, the outer ones 6-7 mm. long, ciliate and pubes- 

 cent: bractlets 6-7 mm. long, ciliate at the tips: corollas 6.5-8 

 mm. long; tube sparingly pubescent above; lobes ovate, ciliate: 

 achenes 2.5-3 mm - l° n g> slightly broadened upward, very minutely 

 papillose, with a prominent tip over each side: pappus-bristles de- 

 ciduous, longer than the achene. 



Melanthera radiata is most closely related to M. aspera (Jacq.) 

 Steud. (M. deltoidea Michx.) from which, however, it differs con- 

 spicuously in habit, the several or many stems arising from a thick, 

 woody root, spreading radially, and decumbent. The leaf-blades 

 too are small and very short-petioled and with sharp teeth. The 

 type specimens were collected in pinelands near the homestead 

 trail near Camp Longview, Florida, May 13-16, 1904 {Small & 

 Wilson 1575).
