The name of coananepilli is given to this species in some parts of central and southern 

 Mexico. It is reputed to have medicinal properties. 



4a. Boerhaavia viscosa apiculata Standley, Contr. Nat. Herb. 12: 383. 1909. 



The type of this has not been reexamined and no additional material has been seen. 

 Perhaps it must be considered a synonym of the species, although it seems different 

 in having obtuse and mucronate leaf blades. The type was collected at Cofradia near 

 Culiacan, Sinaloa, by Mr. T. S. Brandegee, October 20, 1904.

 A specimen collected by Doctor Palmer at Torreon, Coahuila, in October, 1898, is 

 very closely related to this species; it differs merely in having larger heads of flowers 

 and fruit. 



The species seems to be fairly common along the western coast of Mexico in Sonora 

 and Sinaloa. It is frequent in open ground, especially in sandy soil, besides being 

 abundant in waste places and in cultivated fields. The roots, at Fuerte, were said 

 to be used medicinally. The common name was given here as moc.hi. It was stated 

 that the town of Las Moch is farther down the river was given its name because of the 

 abundance of the plant about its site. This statement was contradicted by others, 

 however.
