Pbaieie Clover and Kuhnisteka (Genera Petalostemum 



and Kuhnistera) 



The pretty prairie clovers, Petalostemum, are at home 

 on dry pine barrens, where the clustered stems, with many 

 finely cut leaves, bear pink, lavender, or white clover- 

 like heads, which have a faint and agreeable fragrance. 



Closely related to the prairie clovers is the fall-bloom- 

 ing white kuhnistera, whose ripening heads of soft gray 

 and brown are conspicuous in pinelands in early winter. 

 This member of the pea family is remarkable in that each 

 head of flowers is surrounded by an involucre of bracts, 

 as are the flowering-heads of the composite family. 



Flowers of these two genera differ from the usual form 

 in this family, as the wing and keel petals are nearly 

 alike, and the slender claws of these four petals are united 

 in a tube with the stamens, of which there are but five. The 

 standard, which is broader than the other petals, is sepa- 

 rate. The seedpods are very small. 



Petalostemum Feayi (Petalostemon) . Flowers pink or 

 bright lavender, small, in dense globose spikes about V2 in. 

 long. Stems tufted, 10-20 in. tall. Leaflets 3-9, short, very 

 narrow. Dry sand. Blooming in spring and summer. Fla. 



Petalostemum carneum. Taller and less tufted than above 

 species. Spikes cylindrical, 1 in. long or more. Fla. and 

 Ga.
