172 NATURAL HISTORY OF PLANTS. 
have been described, probably only contains from eight to ten at the 
most, all natives of the north temperate regions of the two Worlds. 
Beside the Limes is placed Schoutenia and 
Muntingia, which also have indehiscent fruits. 
In the former it is dry and monospermous, 
but the calyx is accrescent round it, and form- 
ing at the base a kind of large membranous 
reticulate involucre. In the latter the peri- 
carp surrounds numerous seeds, but it is 
fleshy. Glyphea has also a dry fruit, inde- 
hiscent or nearly so, elongated and polysper- 
mous; the ovary is divided into a variable 
number of cells: there may be as many as ten. 
It is the same in Apeiba; as many as thirty cells have been 
counted in the indehiscent fruit (fig. 185); but it is circular, de- 
pressed, muricate, or covered with prickles or hairs. In Awcistro- 
carpus the tetramerous flower has an ovary with six incomplete cells, 
a 5-adelphous androceum, a coriaceous globular fruit covered with 
hooked prickles (indehiscent?). In Zu/ea the fruit is capsular, 
dehiscent, with winged seeds, but the exterior stamens are sterile, 
and the flower is surrounded by a variable number of bracts forming 
an epicalyx. Græffea has also an epicalyx formed only of three val- 
vate leaves, two multiovulate cells in the ovary, and the stamens all 
fertile. In Mollia the epicalyx disappears, the stamens are united for 
a great distance into ten bundles, superposed five to the sepals and 
five to the petals, while the capsular fruit remains two-celled. Spar- 
mannia (figs. 186-190) and Zytelea generally have tetramerous 
flowers. In the former the exterior stamens are sterile, undulate- 
glandular or moniliform, and the fruit is an almost globose capsule 
with 4-8 cells, all outwardly bristling with prickles. Zrtelea (fig. 191) 
has nearly the same flowers and fruit, but all its stamens are fertile. 
Honckenya has a small number of interior fertile stamens, the 
others being reduced to slender filaments. ‘The fruit is an elongated, 
echinate, loculicidal capsule, the valves, from four to eight in number, 
Apeiba Tibourbou.
