Oxalis crassicaulis, Zuccar. 
Peru. This seems one of the best of those Woodsorrels, 
which yield a tuberous edible root. Amongst others 0.

0. carnosa Mol. and 0. conorrhiza Jaeq. from Paraguay, 
might be tried for their tubers. 
Pachyrrhizus angulatus, Bich. 
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

barren ground, and is likely to add to the value of our 
desert-pastures, although it is annual. Stock relish this 
grass. P. sanguinale, L. and P. glabrwn, Gaudin, are allied 
species. 
Panicum Crus-Galli, L.
