 margin, shorter than the glabrous, milky, persistent petals and ovate cap- 

 sules. Rhizome slender, long; branches above ground 3-6 cm. high, 

 densely leafy at base and scape-like, with few flowers above. 



Dry, sandy places by Rio Chico de Sta. Cruz and by Lago Argentine. 



4. C. PROSTRATA Phil. 



Prostrate annual, usually hairy. Leaves linear, or attenuate below, 

 hispid, marginally appressed-ciliate. Flowers in dense heads, axillary and 

 terminal ; upper leaves as an involucre, not surpassing the flowers. Sepals 

 dorsally hirsute, with compound hairs, mostly tridentate. Corolla purple. 

 Seeds many, shining.
