1 AGINA, L. Prartworrt. (Name from the Latin sagi-

* Very slender, 2-5 inches high: the almost capillary stems several to many, 
subsimple from near the base, usually several-flowered : the lowest flowers 
distinctly axillary : leaves nearly filiform but flattened above, not Pro 
liferous in the upper axils nor forming sterile lateral rosettes ; the basal 
rosette seldom persisting : flowers very small, 4- or 5-parted. 
S. apetala, L. Very slender and commonly glandular-pubescent: 
stems not numerous, procumbent or nearly erect: leaves very slen-
