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

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

 passing the disk, the outer ones 6-^ 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 ^^- ^^^Sy slightly broadened upward, very minutely

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 & 

 Wilsoft 1575).
