2a. Celtis Georgiana Small. GEORGIA HACKBERRY. A shrub or small 

 tree, with pinnately arranged branches, the young twigs puberulent. 

 Leaves small, mostly less than 5 cm. long, short-petioled, obliquely ovate, 

 subcordate, acute or short-acuminate, sharply few-toothed or some of 

 them entire, firm, rough or roughish above, prominently reticulate- 

 veined beneath; peduncles short, 2-8 mm. long, mostly not longer than 

 the diameter of the globose fruit. In rocky places, D. C. to Fla., Mo.

aa. Chenopodium vulvaria L. STINKING GOOSEFOOT. Annual, much- 

 branched, white-mealy, the branches procumbent, 3 dm. long, or more; 

 leaves ovate, entire, 2.5 cm. long, or less, the slender petioles about as long 

 as the blades; flowers in dense short axillary and terminal branched or 

 simple spikes mostly shorter than the leaves; sepals ovate-lanceolate, 

 obtusish. In waste places and ballast, Ont. to Del. July-Sept. 



P. 384, after Sesuvium maritimum, add : 



la. Sesuvium sessile Pers. WESTERN SEA PURSLANE. Much-branched, 

 glabrous, similar to S. maritimum, the stems often copiously verrucose; 

 pedicels 1-3 mm. long, or none; stamens numerous; flowers and capsules 

 slightly larger than in S. maritimum. On beaches, shores and in saline 

 soil, W. Kans. and Colo, to Tex., Cal. and Mex. Also in S. Am. May- 

 Nov. 



P. 385, strike "Minn." from range of Talinum teretifolium and insert: 

 la. Talinum rugospermum Holzinger. ROUGH-SEEDED TALINUM. Sim-

 filaments very slender, red; anthers nearly circular in outline, yellow; 

 style 3-cleft nearly one-third its length into linear stigmatic lobes; seeds

 oblong anthers, and smooth black seeds. In dry soil, Ind. to Wis. and 

 Minn.

 basal leaves long-petioled, deeply palmatifid into linear segments 1.5-3 

 mm. wide; raceme often 3 dm. long or more, loose, the lower pedicels 

 sometimes branched; pedicels very slender, ascending, the lower 5-10 cm.
