cuneate lobes, which are 3-5-toothed at the apex; flowers dark- 
purple, 3/’-5’’ broad; sepals obtusish, not awned; capsule-lobes 
distinctly marked with transverse wrinkles; beak about 5/’ 
long, sparingly pubescent; seeds smooth or striate, not pitted, 
nor reticulate; anther-bearing filaments 10. 
In waste places, Maine to Pennsylvania, New York, Ohio and 
Ontario. Alsoin Washington and Vancouver. Fugitive from Eu- 
trope. Other English names are Pigeon-foot, Starlights, Culverfoot. 
May-Sept. 
2. ERODIUM L’Her. Geran. fl. 7. 1787. 
Herbs, generally with jointed nodes, opposite or alternate 
stipulate leaves, and axillary umbellate nearly regular flow- 
ers. Sepals 5, imbricated. Petals 5, hypogynous, imbricated, 
the 2 upper slightly smaller. Glands?5. Anther-bearing sta- 
meus 5, alternating with as many sterile filaments. Ovary 5- 
7 lobed, 5-celled, beaked by the united styles, the beak termina- 
ting in 5 stigmas; ovules 2in each cavity. Capsule-lobes 1-seeded, the styles elastically dehis- 
cent and coiled spirally at maturity, villous-bearded on the inner;side. Seeds not reticulate. 
(Greek, a heron, from the resemblance of the fruit to its beak and bill. ] 
About 60 species, widely distributed in temperate and warm regions. There are three native 
species in the southwest and several exotic ones have been collected on ballast at the seaports.
