Sida— continued. 
Only three species call for description here. They thrive 
in any rich soil. S. Napwa may be increased by seeds; 
and the others by cuttings, inserted in sand, under a 
glass, in heat. Many plants, formerly included here, are 
now classed under Abutilon. 
S. inzequalis (oblique-leaved).* fl. on lateral peduncles about 
2in. long; calyx segments ovate, acute, ferruginous, pubescent ; 
corolla white, 2in. across when fully expanded, the petals 
clawed, densely glandular-pubescent outside. May. J. 4in. to 
Tin. long, slightly undulated, harshly pubescent, cordate-ovate, 
unequal at base, acuminate; petioles lin. to 2in. long. h. Tft. 
Brazil, 1829, Stove shrub. (B. M. 3436.) 
S. Napza (Napza).* jl. white, large, disposed in umbellate 
corymbs; carpels ten, pointed. Summer. Z. tive-cleft; lobes 
oblong, pointed, toothed. h. 4ft. to 10ft. North America. A 
tall, smooth, hardy, herbaceous perennial. (B. M. 2913.) 
S. sessiliflora (sessile-flowered), fl. yellow, small, somewhat 
glomerate, sessile, axillary and terminal; corolla scarcely twice 
the length of the calyx. August to November. l. cordate, acute, 
serrated, h. 3ft. South America, 1827. Stove sub-shrub. 
(B. M. 2857.) 
SIDALCEA (from Sida, and Alkea, an ancient Greek 
name, used by Dioscorides for some Malva; alluding to 
the appearance and alliances of the plants). ORD. Mal- 
vacee. A genus comprising eight species of hardy, 
mostly perennial herbs, with the habit of Malva or 
Althea, natives of Western North America. Flowers 
shortly pedicellate or sessile, disposed in terminal ra- 
cemes or spikes; calyx five-cleft; petals rose-purple or 
white; staminal column duplex at apex. Leaves mostly 
lobed or parted. S. candida and 8. malveflora, perhaps 
the only species in cultivation, require culture similar 
to Malva (which see). 
S. candida (white). /l. white, in terminal racemes, freely pro- 
duced. Summer. l. roundish, seven-lobed, glossy, long-stalked. 
h. 2ft. to 3ft. Colorado, 1882. 
S. malvzeflora (Mallow-flowered). fl., corolla lilac; racemes 
many-flowered ; pedicels twice as long as the calyx. Summer. 
l., radical ones orbicular, loosely five to nine-lobed or incised- 
crenate ; primary ones sub-truncate at base ; cauline ones pro- 
foundly seven to nine-cleft ; segments trilobed, toothed at apex, 
the uppermost ones entire. Stem twiggy, slender. h. 1}ft. Texas, 
1838. (B. R. 1036, under name of Sida malvefora.) SYN. Cal- 
lirhoe spicata (R. G. 737.) s 
SIDE-GRAFTING. A method of Grafting that 
may be adopted for supplying a branch or stem to a tree 
when one is deficient; it may be practised without cutting 
away the head of the stock. For mode of application, see 
SIDERITIS (an old Greek name, used by Dioscorides 
for several plants, and derived from sideros, iron; so 
named on account of a supposed property of healing 
flesh-wounds inflicted by iron). Ironwort. Syns. Burgs- 
dorfia, Hesiodia, Marrubiastrum. ORD. Labiate. A 
genus comprising about forty-five species of hardy or 
half-hardy, often woolly or softly pilose herbs, sub- 
shrubs, or shrubs, natives of the Mediterranean region 
and the Canary Islands, numerous in the Orient. Flowers 
often yellowish, small; calyx tubular, with five erect, 
usually somewhat spiny teeth; corolla tube included ; 
limb bilabiate, the upper lip entire, emarginate, or bifid, 
the lower one trifid, its middle lobe much the largest ; 
stamens four; whorls six to many-flowered, axillary or 
interruptedly or densely spicate. Nutlets ovoid, smooth. 
Leaves entire or toothed; floral ones reduced to bracts, 
or the lower cauline ones conformed. The species (a re- 
presentative selection of which is given below) prefer 
a dry, sandy or chalky soil. Propagation may be effected 
by seeds, by cuttings, or by divisions. All have yellowish 
flowers, produced in summer.

SIDEROXYLON (from sideros, iron, and wylon, 
wood ; alluding to the very hard wood furnished by 
the various species). Syns. Achras and Sapota (as far as 
the Old World species are concerned), Robertsia. ORD. 
Sapotaceœ. A genus comprising nearly sixty species of 
stove or greenhouse, glabrous or pubescent trees or 
shrubs; they are broadly dispersed through the tropics, 
a few are found in the extra-tropical regions—South 
Africa, Australia, and New Zealand—and one in Madeira. 
Flowers usually small, sessile or pedicellate, fascicled | 
at the nodes or axillary, five-parted; calyx segments 
closely imbricated; corolla broad or tubular-campanu- — 
late. Berries ovoid or globose. Leaves coriaceous, 
scattered. The fruits of S. dulcifiewm have a very sweet 
taste, and are known, with others, in West Africa, under 
the name of Miraculous Berry. Several of the species 
have been introduced, but they are of little or no value 
from a garden standpoint. =

Prague, 1785-1844, a botanist who travelled in the 
East), Syn. Trachymene (of De Candolle). Orp. Um- | 
bellifere. A genus comprising fourteen species of green- 
house, rigid herbs with a perennial (almost woody) stock

_Flowers white, small; calyx teeth small, but usually con- 
spicuous; petals entire; involncral bracts small; umbels 
compound or rarely simple, terminal. Leaves all entire,

without stipules. The under-mentioned species is, per- 
haps, the only representative of the genus which has 
been introduced to English gardens, and is probably not 
now in cultivation. For culture, see Trachymene.
