STERCULIA CEAE 
595 
Limonium L. (sea-lavender) and 2 others, on the coast of Brit. 
Infl. compound, mixed, the total infl. being a spike, the partial a 
drepanium. The firs, of many sp., eg. S. Limonium , are heterostyled 
like those of Primula. 
Stauntonia DC. Lardizabalaceae. 2 sp. China, Japan. 
Staurostigma Scheidvv. Araceae (vn). 5 sp. Brazil. 
Steironema Rafin. Primulaceae (ill). 4 sp. N. Am. 
Stelis Sw. Orchidaceae (12). 150 sp. trop. Am. 
Stellaria Linn. (incl. Malachium Fries). Caryophyllaceae (11. 1). 80 sp. 
cosmop. ; 7 in Brit, (chickweed, stitchwort). Of the Brit, sp., S. media 
Cyrill. has small homogamous firs, that fertilise themselves in absence 
of insects; it flowers all the year round, and in winter (apparently on 
account of weak light, cold, &c.) the firs, are often cleistogamic 
(p. 98). The number of sta. is most often 3, but varies a good deal 
(see Burkill, Linn. Soc. Journ . xxxi. 1895). The flrs. of S. gra - 
minea L. are larger and protandrous, but with autogamy, whilst in 
S. Rolostea L. the flrs. are still larger and very protandrous with but 
little self-fertilisation. 
In S. media there is a double row of hairs on each internode. 
Water poured on the plant runs down these, and Stahl explains them 
as adaptations similar to drip-tips (cf. Ficus), for drying the plant 
after rain; Lindman thinks they convey the water to the leaf-axils, 
where it is absorbed by the plant. 
Stemonaceae. Monocotyledons (Liliiflorae). 3 gen. with 8 sp.,E. Ind., 
Am., Austr., &c. The chief genus is Stemona Lour. See Nat . Pfl ., 
and Lachner-Sandoval in Bot. Centr. 50, p. 65, 1892. 
Stenophragma Celak. Cruciferae (iv. 15). 1 sp. Spain. 
Stenorhynchus Rich. = Spiranthes Rich. 
Stenospermation Schott. Araceae (11). 4 sp. trop. Am., sub-andine. 
Stenotaphrum Trin. Gramineae (v). 4 sp. Polynes., Am. .S', ameri- 
canum Schrank is useful for binding drift-sand (cf. Ammophila). 
Stephanotis Thou. Asclepiadaceae (11. 4). 15 sp. Madag., Malaya, 
Cuba. Largely cultivated for their scented flrs. 
Sterculia Linn. Sterculiaceae. 90 sp. trop. Firs, unisexual, apetalous. 
Sterculiaceae. Dicotyledons (Archichl. Malvales). 48 gen. with 660 
sp. chiefly trop. Trees, shrubs, or herbs, with alt. stip. leaves; some 
are lianes. Firs, in complex cymes, $ , usually regular, 5-merous. 
K (5), valvate, with no epicalyx ; C often absent or small, convolute; 
A in 2 whorls, the outer staminodial or o, the inner often branched, 
all more or less united into a tube, anthers 2-loc.; G usually (5), with 
2 — 00 anatropous ovules in each, with the micropyle outwards; style 
simple, lobed. Fruit various, often a schizocarp. Endosperm. Cola 
and Theobroma (cacao) are economically important. Chief genera : 
Dombeya, Hermannia, Melochia, Buettneria, Theobroma, Helicteres, 
Sterculia, Cola. Placed in Malvales by Benth. -Hooker, in Columni- 
ferae by Warming.
