the calyx; carpels 5, kidney-shaped, with smooth sides, at length 2-valved. 



Rock Island in the Mississippi, Illinois, Engelmann, Parry. Aug. 



2. M. COCCineum, Gray (Sida coccinea, Pursh), a low and hoary 

 perennial, with 5-parted or pedate leaves, and short spikes or racemes of

 more, tipped with capitate stigmas : the ripe fruit separating into as many 1- 

 seeded carpels, which are closed, or commonly 2-valved at the top, and tardily 

 separate from the axis. Seed pendulous. Embryo abruptly bent ; the radicle 

 pointing upwards. — Flowers perfect. (A name used by Theophrastus.) 



1. S. Napaea, Cav. A smooth, tall (4° -10° high) perennial; leaves 5-cleft, 

 the lobes oblong and pointed, toothed; flowers (white) umbellate-corymbed, large;

 the specific name, but it cannot be called a spine. — Waste places : common 

 southward. (Nat. from Trop. Amer. or Afr.)
