OF HORTICULTURE. 533 
Synadenium—continued. - 
solitary, with bifid, recurved stigmas. Leaves scattered, 
obovate, entire, rather thick. Only one species has been 
introduced. It thrives in a thoroughly well-drained, 
sandy loam, with the addition of a little well-rotted 
cow-dung. Propagation may be effected by cuttings, 
thoroughly dried at the base, inserted in sand, and 
occasionally very slightly moistened.

deeply keeled above; petioles channelled above; sheaths 
short, opening. ‘Trunk slender, annulate, often stoloni- 
ferous. S. fibrosus, the only species introduced, is an 
exceedingly graceful Palm, requiring similar treatment to 
Chamezdorea (which see).

spathe; peduncles fascicled or solitary, short. Leaves 
petiolate; primary ones sagittate; adults pedately three 
to nine-cut; petioles elongated; sheaths persistent, 
accrescent. The species introduced are described below. 
They are easily grown in a house where a high tem- 
perature and a moist atmosphere are maintained. An 
open compost of loam and peat, or leaf mould, to which 
some coarse sand should be added, is best; the plants 
are not, however, very fastidious regarding soil. Plenty 
of water and frequent syringings are essential in the 
summer or growing season; and no more shade should be 
applied than is requisite to keep the leaves from scorching. 
Propagated easily by dividing the stems into lengths con- 
sisting of about three joints, and inserting them in pots, 
in a brisk heat. These soon become established, and make 
new growth at the top. Any old plants which get too high 
for the house they occupy may have their tops cut off 
and inserted as large cuttings: these soon re-establish 
themselves.

peduncles very numerous, two to seven from one axil, slender, 
nearly equalling the spathe. l. acute; anterior lobes oblong-

SYNNOTIA (named in honour of W. Synnot, who 
collected many plants at the Cape of Good Hope). Erro- 
neously spelt Synnetia. ORD. Iridew. A small genus 
(three species) of pretty, greenhouse, bulbous plants, 
natives of South Africa. Flowers rather large, sessile ; 
perianth funnel-shaped, with erecto-patent, unequal lobes ; 
stamens affixed at base of throat; spathes scattered at 
the sides of the stem, rather broad, cut or fimbriate- 
toothed at apex, one-flowered. Leaves few, flat, linear- 
ensiform, flaccid. Stem simple or very slightly branched. 
Propagation is readily effected by seeds; or by offsets, 
which are freely produced. Seeds should be sown in 
pans of sandy soil, about September, and placed in a 
cool frame. The young plants may remain in the seed- 
pans for the first year, when they should be either 
potted singly or planted out. Three or four years 
elapse before they flower. Propagation by offsets is 
a much quicker method, as the plants then generally 
flower the second year. Synnotias, cultivated as pot 
plants, are adapted for conservatory and cool 
decoration, in spring, The bulbs should be potted rather 
firmly, in sandy loam and leaf soil, during October, © 
placing about six or eight in a 5in. pot, and covering
