 filiform, with revolute, scabrous edges ; stipulas fuscescent, ciliat- 

 ed with bristles ; cymes terminal and axillary, crowded. 1. S.

 calyx glabrous, acutely 4-toothed ; anthers exserted. Native

 the size in all its parts. Fruit unknown, therefore the genus 

 is doubtful.

 fruticose, and is as well as the branches, terete and glabrous ;

 8. but not of Nees. Bigelowia linifolia, Spreng. syst. 1. p. 404. 

 Fruit unknown. Anthers blue. 



Flax-leaved Borreria. PL 1 foot. 



Cult. The species of Borreria are of most easy culture. A 

 light soil suits them best ; and cuttings of the perennial and 

 shrubby kinds strike root readily in the same kind of soil, in 

 heat. The annual kinds require the treatment of other tender 

 annuals. 1
