OXALIDACEAE. 



by broken ridges. [Greek, yellow oxalis.] About 50 species, of wide dis- 

 tribution. Type species: Oxalis corniculata L. 



Stems creeping, like the branches, with scattered lax hairs. 1. X. corniculata. 



Stems not creeping, like the branches, closely pubescent with ap- 



pressed hairs. 



2. X. stricta. 

 1. Xanthoxalis corniculata (L.) 

 J. K. Small. YELLOW PROCUMBENT 

 WOOD-SORREL. Stem branched at 

 the base, the branches 2'-15' long, 

 creeping, somewhat pubescent with 

 spreading or loosely appressed hairs; 

 leaflets deep green, 3"-6" broad or 

 sometimes larger, ciliate and com- 

 monly with scattered hairs on the 

 surface; pedicels minutely strigil- 

 lose; sepals oblong to oblong-lance- 

 olate, ciliate at the apex or only 

 near it; petals 3"-5" long; filaments 

 glabrous; capsule 4"-7" long. [Ox- 

 alis corniculata L. ; 0. microphylla 

 of Lefroy; 0. repens of Keade.] 



Abundant in waste and cultivated 

 grounds. Introduced. Widely dis- 

 tributed in warm and tropical regions. 

 Probably native of tropical America. 

 Flowers from autumn to summer. 



2. Xanthoxalis stricta (L.) J. 

 K. Small. UPRIGHT YELLOW WOOD- 

 SORREL. (Fig. 220.) Stems tufted 

 on woody rootstoeks, or sometimes 

 from annual roots, strigillose. Leaves 

 usually numerous ; leaflets bright 

 green, 4"-8" broad, glabrous or with 

 a few scattered hairs; pedicels strigil- 

 lose; sepals oblong or linear-lanceo- 

 late, 2 "-3" long, sparingly ciliate, 

 more or less pubescent on the back; 

 petals 3"-6" long, pale or yellow; 

 longer filaments glabrous; capsules 

 stout, columnar, 8" -15" long. [Ox- 

 alis stricta L. ; 0. corniculata stricta 

 Sav.; ?0. Dillenii of Keade.] 



Occasional in waste and cultivated 

 grounds, flowering in spring and summer. 

 Native of temperate North America. 



Caudoxalis Bowieana (Lodd.) J. K. Small, BOWIE'S WOOD SORREL, South 

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

 scapose purple flowers li-'-2' wide, its rootstoeks bearing distant pointed 

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

 Lodd.] 



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

 Europe, as Bermudian, is manifestly an error.
