158 ECONOMIC BOTANY OF ALABAMA 



ARISTOLOCHIACEAE. Hkart-lf.af Family 



Includes aluiut •') genera and 200 species, mostly South Amer- 

 ican woody vines. Some cultivated for ornament, and some 

 medicinal. 



ARISTOLOCHIA, L. 



This genus is re])resented in Alabama l)y two or three herbs 

 (Virginia snake-root, etc.) and one or two woody vines, which are 

 called pipe-vine or Dutchman's pipe (from the curiously shaped 

 flowers) in the books, but seem to have no bona-fide common 

 name in this part of the world. The flowers and fruit are not 

 often seen, because they are apt to be high up in the trees, and it 

 is possible that every vine does not bloom every year. (I never 

 saw the flowers until l!t27.) The heart-leaf (.Isantni) belongs to 

 the same family. 



Aristolochia tomentosa, Sims. 



A high-climbing twining vine, with very porous stems, an 

 inch or less in diameter, and large heart-shaped deciduous leaves. 

 Blooms in April, and ]^erhaps later. It is occasionally cultivated 

 for ornament, but is liable to spread and become a nuisance. 



(irows mostlv on banks of rivers and creeks, in rather rich 

 soils.

 Tennessee River near Florence (not seen in leaf, but presumed to be this 

 species). Morgan County.
