Sageretia continued. 



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

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

 rated; stipules minute, deciduous. 8. hamosa, perhaps 

 the only species introduced, is probably lost to 

 cultivation in this country. 



SAGE ROSE. An old name for the genus 

 Cistus. See also Turnera ulxnifolia. 



SAGINA (from sagina, fatness ; alluding to 

 the presumed nourishing qualities of the plants 

 for sheep). Pearl Weed; Pearlwort. OBD. 

 CaryophylleoB. 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. 

 8. 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). /Z. white ; petals twice as large as 

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

 linear, awned, rather stiff, glabrous, in bundles. Stems creeping, 

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



S. p. aurea (golden). This only differ 

 golden-yello 



from the type in its 

 foliage. It is a good plant for carpet bedding. 



SAGITTARIA (from sagitta, an arrow; alluding to 

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

 A lismacecB. 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, spicate 

 or panicled, pedicellate, three-braoted (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- 

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

 readily increased by division. All flower in summer. 

 S. aontlfolla (acute-leaved). A synonym of S. graminea. 

 S. graminea (grass-like). /!., lower whorls fertile; bracts 

 usually connate; pedicels slender; scape very slender, erect, 

 1ft. to 2ft. high. I. varying from ovate-lanceolate to linear, or 

 reduced to broad and acute phyllodes, scarcely ever sagittate. 

 North America, 1812. SYN. S acutifolia. 



S. heterophylla (variable leaved).* fl. of the lowest whorl fer- 

 tile and almost sessile, the sterile ones on long pedicels ; bracts 

 obtuse; scape weak, 2ft. to 3ft. high, at length procumbent. 

 I lanceolate or lanceolate-oval, entire or with one or two narrow, 

 basal, sagittate, appendages. North America, 1822. 

 S. h. rigida (rigid). I. rigid, narrowly lanceolate, acute at both 

 ends ; petioles stout. A tall form. (B. M. 1652, under name of 

 S. rigida.) 



S. lanoifolia (lance-leaved). fl. on slender pedicels ; several of 

 the lower whorls fertile ; bracts acute or acuminate ; scape 2ft. 

 to 5ft. high. I. lanceolate or lanceolate-oblong, rarely linear all 

 with a tapering base, 6in. to 18in. long, on long, stout petioles,

S. L. angustifolia (narrow-leaved). A variety having the blades 

 of the leaves very narrow or all deficient. Plant much smaller, 

 in all its parts, than the type. (B. B. 1141, under name of 

 S. angustifolia.)
