five-parted. Leaves sub-opposite, shortly petiolate, oblong 

 or ovate, pinnately nerved and reticulated, entire or ser- 

 rated : stipules minute, deciduous. S. iiamosa, perhaps 

 the only species introduced, is probably lost to 

 cultivation in thi.s country. 



SAGE ROSE.

SAGINA (from nayina. fatness ; alluding to 

 the presumed nourishing qualities of the plants

 Co ryoph yllece. A genus comprising about 

 eight species of small, tufted, annual or 

 perennial herbs {mostly weeds), natives of the 

 temperate and frigid regions of the Northern 

 hemisphere, one being also broadly dispersed 

 over the Southern hemisphere. Flowers small, 

 usually long-pedicellate ; sepals four or five ; 

 petals four or five, entire or loosely emarginate, 

 sometimes minute or wanting. Leaves subulate. 

 S. pilifera is a hardy evergreen, suitable, in 

 some situations, as a substitute for grass 

 edging. " To raise from seed, sow in May. 

 To establish an edging from plants, plant 

 patches in September, about 2in. apart. They 

 require to be frequently beaten flat with the -' 



back of the spade. It seems too apt to become 

 patchy to be relied on for any extensive 

 surface, like a lawn'' (N. E. Brown), 



S. pilifera (hair-bearing). Jf. white : petals twice as large as 

 the calyx ; peduncles very long. July and August. I. opposite, 

 linear, awiied. rather stifi^, glabrous, in bundles. Stems creeping, 

 liranched, tufted, h. 2in. Corsica, 1826.

SAGITTARIA (from sagitta, an arrow ; alluding to 

 the prevalent form of the leaves). Arrow -head. Ord. 

 AlisniacecE. A genus consisting of about fifteen species 

 of stove, greenhouse, or hardy, marsh-loving, usually 

 erect, perennial herbs, inhabiting temperate and tropical 

 regions. Flowers white, usually ternately whorled, spieate 

 or panicled, pedicellate, three bracted (in one species 

 one-bracted) at the nodes ; perianth segments six, in 

 two series, the outer ones persistent, the inner ones 

 larger, petaloid, deciduous ; stamens nine or more, 

 usually numerous; scape erect, slender or robust. 

 Leaves on long or often thick petioles, elliptic-lanceolate 

 or sagittate, often pellucid-dotted or lineolate. The 

 under-mentioned species are hardy, except where other- 

 vpise stated. They require a loamy soil, and may be 

 readily increased by division. All flower in summer.
