2. X. stricta. 

 1. Xanthoxalis corniculata (L.) 

 J. K. Small. Yellow Procumbent 

 Wood-sorrel. Stem branched at

 creeping, somewhat pubescent with 

 spreading or loosely appressed hairs; 

 leaflets deep green, 3"-6'' broad or 

 sometimes larger, ciliate and com-

Abundant in waste and cultivated 

 grounds. Introduced. Widely dis-

Candoxalis Bowieana (Lodd.) J. K. Small, Bowie's Wood Sorrel, South 

 African, a very decorative species with orbicular-obovate rounded leaflets and 

 scapose purple flowers lV-2' wide, its rootstocks bearing distant pointed 

 tubers, is planted in many gardens, flowering in winter. [Oxalis Bowieana 

 Lodd.] 



Michaux's record of Oxalis Acetosella L., of boreal North America and 

 Europe, as Bermudian, is manifestly an error.
