berry) : Ribes.

Saxifrageae (Benth. -Hooker) = Saxifragaceae. 
Saxifraginae (Warming). The 18th cohort of Choripetalae (p. 137). 
Scabiosa (Tourn.) Linn. (incl. Knautia Linn., PterocefihalusVdj\\. y Sue - 
cisa Neck.). Dipsacaceae. 86 sp. Eur., As., Afr., esp. Medit. ; 3 in 
Brit., of which S. (K.) arvensis L. (scabious) and S. Succisa L. 
(devil’s-bit scabious) are common. The former has a large head of 
firs. ; the corolla of these is drawn out upon the outer side (cf. Com- 
positae), and this the more the further they are from the centre of the 
head. Honey is secreted by the upper surface of the ovary, and 
protected from rain by hairs in the tube. The sta. are ripe first, while 
the style with immature stigmas is quite enclosed in the corolla; later 
the sta. wither and the style occupies their place. The stigmas of the 
various flowers upon the head ripen nearly simultaneously. 
Scaevola Linn. Goodeniaceae. 60 sp. Austr. , Polynes., coasts of trop. 
Afr., As., Am. S. Koenigii Vahl furnishes a kind of rice paper ; its 
pith is squeezed flat like that of Fatsia. 
Scandix Tourn. ex Linn. Umbelliferae (5). 12 sp. Eur., As., N. Afr. 
S. Pecten- Veneris L. (Venus’ comb) in Brit. The ripe mericarps 
separate with a violent jerk. 
Scheuchzeria Linn. Juncaginaceae. 1 sp., S. palustris L., N. temp 
and arctic, incl. Brit. ; a marsh plant. 
Schinus Linn. Anacardiaceae (ill). 4 sp. Mexico to Argentina. 
S. Molle L. yields American mastic (resin). 
Schismatoglottis Zoll. et Mor. Araceae (v). 10 sp. Malaya. At 
the top of the spadix, above the <? firs., are sterile firs, consisting of 
staminodes. 
Schivereckia Andrz. = Alyssum Tourn. 
Schizaea Sm. Schizaeaceae. 16 sp. trop. and subtrop. The sporangia 
form a double row on the lower surface of each of the reduced fertile 
pinnae. 
Schizaeaceae. Filicineae Leptosporangiatae (Homosporous). 5 gen. 
with 70 sp., chiefly trop. Am.; a few subtrop. or temp. They are 
mostly small ferns with but little stem. Lygodium is a curious leaf- 
climber. As in Osmunda, the sporangia are borne (exc. in Mohria) 
on special pinnae of the leaf, distinct from the ordinary vegetative 
pinnae. The sporangia are sessile, usually without indusium ; at the 
apex is a cap-like annulus, and the sporangium dehisces longitudinally. 
Chief genera : Schizaea, Aneimia, Lygodium, Mohria. 
Schizandra Michx. Magnoliaceae (2). 7 sp. trop. and warm temp. As.;
