I. ASPARAGUS L. 



Stem at first simple, fleshy, scaly, at length much branched; the branchlets fili- 

 form and mostly clustered in the axils of the scales in the following species, flattened 

 and linear. Flowers small, solitary, umbelled or racemed. Perianth-segments 

 alike, separate, or slightly united at the base. Stamens inserted at the bases of 

 the perianth-segments; anthers introrse Ovary sessile, 3-celled; ovules 2 in each

 drooping on filiform jointed peduncles; perianth campa'nulate, about 6 mm. long, 

 the segments linear ; stamens shorter than the perianth ; berry red, about 8 mm. 

 in diameter. Escaped from cultivation and naturalized, especially along salt 

 marshes, N. B. to Va. and locally in waste places in the interior. Native of 

 Europe. May-June. 



2. CLINTONIA Raf. 



Somewhat pubescent scapose herbs, with slender rootstocks, erect simple scapes, 

 and few broad petioled sheathing basal leaves, the bractless flowers umbelled at the 

 summit of the scape in our species. Perianth-segments equal or nearly so. Sta- 

 mens 6, inserted at the bases of the perianth segments; filaments filiform ; anthers 

 laterally dehiscent. Ovary 2-3-celled; ovules 2-several in each cavity; stigma 

 obscurely 2-3-lobed. Berry globose or oval. [Name in honor of De Witt Clinton,
