422 NATURAL HISTORY OF PLANTS. 
tropous ovules are seen, with superior and exterior micropyle, tardily 
separated from each other by an incomplete false oblique partition. 
The fruit is a three-shelled drupe, whose rather thin mesocarp 
covers three osseous stones, often divided by a false woody partition 
(transverse or oblique, and complete or incomplete) into two super- 
posed cells, each of which contains an obliquely descending seed, 
folded upon itself in the shape of a horseshoe, the coats covering a 
fleshy albumen. The axis is occupied by a curved hook-shaped em- 
bryo, with narrow, elongated, semicylindrical, incumbent cotyledon, 
and superior cylindrical radicle. © The two species of Creorum known 
are shrubs, small in size, more or less bitter, unarmed, glabrous or 
velvety,' with alternate, simple, entire leaves, articulate at base, not 
punctuate, or only glandular towards the edges. The flowers’ are 
axillary, solitary, or disposed in few-flowered cymes, with a peduncle 
connate for a variable distance with the axile leaf and articulate 
pedicels. They inhabit the Mediterranean region, and the isles on 
the North-Western coast of Africa.’ 

XI. ZYGOPHYLLUM SERIES (Beancapers). 
Zygophyllum has nearly regular hermaphrodite flowers. If we take, 
for example, those of 7. Fubago’ (figs. 497-502), an eastern species, 
often cultivated in the garden in France, we see that the receptacle 
is convex, bearing, first, five sepals, with quincuncial imbricated præ- 
floration, and five alternate petals, with short claws° imbricated in a 
variable way, or contorted in the bud. ‘The stamens are ten in 
number,’ superposed five to the sepals, and five, a little shorter, to 
the petals. They are composed of a free exserted filament internally, 

1 The hairs are attached by the middle of 
their length.

more or less dark in most of the species which 
often have the rest of the limb yellow.
