 Dond6) ; " tronador " (Colima). 



Palmer reports that in Colima the fiber extracted from the stems is utilized 

 in making rope, hammocks, and nets. The stems are buried in mud for three 

 or four days, then washed, and the bark (which contains the fiber) stripped 

 from the stems by hand. 



22. Abutilon incanum (Link) Sweet, Hort. Brit. 53. 1827. 

 Sida incana Link, Enum. PI. 2: 204. 1822.

 often purple at base, 6 to 9 mm. long; carpels 6 to 7 mm. long, minutely 

 tomentose. " Pelotazo chico " (Sinaloa). 



This, like A. trisulcatum, is a source of fiber. A. racemosum Schlecht.* is 

 probably a synonym of this species.
