 Oxalis crassicaulis, Zuccar. 



Peru. This seems one of the best of those Woodsorrels, 

 which yield a tuberous edible root. Amongst others 0. 

 tuberosa, Mol. and 0. succulenta, Barn, from Chili, as well as 

 0. camosa Mol. and 0. conorrhiza Jacq. from Paraguay, 

 might be tried for their tubers. 



Pachyrrhizus angulatus, Rich. 



Prom Central America rendered spontaneous in many 

 tropical countries. A climber, the horizontal starchy roots 

 of which attain a length of 8 feet and a thickness of many

 species. 



Panicum Crus-Galli, L-
