alone ov half surrounding one ovary (female flower) which is not enclosed ti a 
separate involucre, Ovary 2-8-celled, with 1 pendulous ovule in each cell. 
*#Ovary ov female flower, when present, enclosed in the same 
involucre as the stamens; involucre shortly tubular, 
cup-like or 4-angled, sometimes open to half-way down 
on one side, never open to the very base nor composed 
of entirely free segments. 
+Inyolucre a cup or short tube cut into a fringe of filiform 
segments at the top, with an erect oblong entire lobe 
outside and behind, glandular at its apex and over- 
topping the fringe ‘ . 1. STENADENIUM. 
ttInvolucre a cup (not 4-angled), with a an ents rim-like 
gland or 2-8 green or coloured glands at its margin, 
surrounding an inner circle of 4-8 (usually 5) thin 
and usually fringed or toothed lobes, often with a 
pair of scale-like or conspicuous green or coloured 
bracts at its base or enclosed in an entire or 2-lobed 
obliquely cup-like bract. 
Involuecre with one continuous rim-like entire or rarely 
4-crenate erect or spreading gland entirely 
surrounding it, or open on one side, occasionally 
with 1-5 cut-like notches separating the gland 
into contiguous and usually unequal segments, 
but scarcely forming distinct glands. (See also 
4, Euphorbia.) 
Perennials with thick cylindric fleshy stems or with 
annual unbranched stems from a tuberous root- 
stock. Bracts free or combined into an oblique 
entire or 2-lobed cup longer than and partly 
concealing the involucre, which is open on one 
side : : : 5 3 c ~ 
Branching shrubs or small trees; bracts free, 
scarcely or not exceeding the rim of the in- 
volucre, Which is usually entire, but sometimes 
has 1-5 cut-like notches . 5 : 
Involucre with 2-8 distinct glands, contiguons or 
equally spaced, entire and with or without petal- 
like appendages or 2-horned or divided into 3-15 
entire or forked processes. (In a few succulent 
species of Kuphorbia the glands are united into a 
continuous rim and then are technically not dis- 
tinguishable from Synadenium, and a few species 
of the latter genus have the gland divided by 
cut-like notches and are then technically scarcely 
distinct from Euphorbia.) 
Fruit separating into 3 lobes or cells, which open 
down the inner face to liberate the seed, not 
fleshy or but slightly so in a few succulent
