 the New York Botanical Garden. I have collected this at Tampa, my 

 number 9643. Scoparia dulcis varies considerably in size of corolla, 

 but no other character correlates with this, nor do larger-flowered plants 

 occur in an environment distinct ecologically or geographically. Wide 

 gradation in corolla-size may be found within one colony. 



Waste places, cultivated ground, especially in sandy soil, southern 

 Georgia to southeastern Texas and southward; wholly within the 

 Coastal Plain. A wide -spread weed of lowland Tropical America. 



Flowering and fruiting in subtropical Florida throughout the 3'ear, 

 northward flowering in summer (from about May to September), 

 and soon ripening fruit. Corolla white, at times the lobes slightly 

 pinkish.
