+ Lower leaves ovate, rather abruptly contracted into slender petioles. 
S. mepia, Smith. (Common Cuickweep.) A low annual: stem

pubescent: leaves ovate, acute or shortly acuminate, the lower sub- 
cordate on slender ciliated petioles; the upper cauline short-petioled 
or sub-sessile; the floral reduced and bractlike: pedicels filiform : 
flowers smaller than in the preceding: sepals in anthesis but 4 ling
