Sageretia—continued. 
five-parted. Leaves sub-opposite, shortly petiolate, oblong 
or ovate, pinnately nerved and reticulated, entire or ser- 
rated; stipules minute, deciduous. S. hamosa, perhaps 
the only species introduced, is probably lost to 
cultivation in this country. 
SAGE ROSE. 
Cistus. 
SAGINA (from sagina, fatness ; alluding to 
the presumed nourishing qualities of the plants 
for sheep). Pearl Weed; Pearlwort. ORD. 
Caryophyllee. 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. 
_§. 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. p. aurea (golden). This only differs from the type in its 
golden-yellow foliage. It isa good plant for carpet bedding. 
SAGITTARIA (from sagitta, an arrow; alluding to 
the prevalent form of the leaves), Arrow-head. ORD. 
Alismacee, 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-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, 
y numerous; scape erect, slender or robust. 
Leaves on long or often thick petioles, elliptic-lanceolate 
An old name for the genus 
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. acutifolia (acute-leaved). A synonym of S. graminea. 
graminea (grass-like). f lower whorls fertile; bracts 
usually connate ; icels slender; scape very slender, erect, 
lft. to 2ft. high. l. varying from ovate-lanceolate to linear, or 
reduced to broad and acute phyllodes, scarcely ever sagittate.

basal, sagittate, appendages. North America, 1822. 
S. h. rigida (rigid). J. rigid, narrowly lanceolate, acute at both 
ends; petioles stout. A tall form. (B. M. 1632, under name of

house. (A. B. R. 335; B. M. 1792.) 
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. R. 1141, under name of 
S. angustifolia.) 3
