2. FLOERKEA Willd. Neue Schr. Ges. Nat. Freuude 

 Berlin 3 : 448. 1801. 

 Low slender annuals, simple or branched a little from the base. Leaves simply pin- 

 nately dissected. Flowers inconspicuous on axillary, arcuate, recurved peduncles. Sepals 

 3, slightly imbricate in aestivation, spreading in fruit. Petals 3, white, open in aestiva- 

 tion, about half as long as the sepals. Stamens 6 ; filaments subulate, distinct, those op- 

 posite the petals shorter ; anthers didymous, introrse, opening longitudinally. Ovaries 2 or 

 3 ; style 2- or 3-cleft at the apex ; stigmas capitate. 

 Type species, Floerkea proserpinacoides Willd. 

 Peduncles longer than the petioles and often equaling the leaves ; sepals 



ovate, 2-3 mm. long; carpels 2-2.5 mm. 1. F. occidentalis. 



Peduncles rarely equaling the petioles ; sepals lanceolate or lance-ovate, 3-5
