3. EHRETIA, L. {George Dionysius Ehretya. gifted botanical painter of

 in open cymes or panicles, or rarely almost solitary. — Benth. & Hook. 1. c. 



E. elliptica, DC. Tree 15 to 50 feet high : leaves oval or oblong, sometimes serrate, 

 nearly smooth and glabrous or (with the branchlets and open cymes) minutely hirsute-pu- 

 bescent and the upper face very scabrous : divisions of the calyx broadly lanceolate, acu- 

 minate, as long as the campanulate tube of the corolla : drupes yellow, globose, of the 

 size of small peas (the tliin pulp edible). — Prodr. ix. 503; Torr. Mex. Bound. 136; Miers,

4. COLDfiNIA, L. {Dr. Cadwallader Colden, Colonial Lieut.-Governor 

 of New York, a correspondent of Linnseus.) — Low herbaceous or suffrutescent 

 plants, canescent or hispid ; with small and mostly white flowers sessile and 

 usually in clusters; the original species a prostrate annual, with usually 4-merous 

 flowers and coarsely toothed leaves, the strong simple veins of which run to the 

 sinuses. (Lam. 111. t. 89 ; Ga^rtn. Fruct. t. 68, embryo wrongly figured.) Genus 

 extended by the addition of several North and W. South American species, 

 diverse in habit and minor characters, which might well form more than half as 

 many subgenera as there are species, but may be ranked under three. (Insertion 

 of stamens probably both high and low in the same species.) — Gray, Proc. Am.

§1. EucoLDENiA, Benth. Fruit merely 4-sulcate ; the nutlets with plane 

 contiguous sides and thick crustaceous walls, or in one sj)ecies reduced by abortion 

 to a single cell : corolla not appendaged within : stamens equally inserted : veins 

 of the leaves straight and simple. — Stegnocarpus & Ptilocalyx, Torr. 



C. canescens, DC. Prostrate or procumbent, with somewhat ligneous perennial base, 

 white-sericeous or tomentose : leaves (barely half inch long) ovate or oblong, entii-e, petioled, 

 obscurely veined : flowers solitary or in small clusters at the axils or forks : calyx-lobes 

 linear-lanceolate : fruit depressed-globose ; the four thick-walled nutlets smooth and rounded 

 on the back, obscurely rugose on the plane sides, pointless : embryo slightly curved. —
