carica_; ♀-plants, which have only seed-flowers, and bear the edible
Figs, and ♂-plants (called “Caprificus”), which bear inedible fruits,
and have ♂-flowers at the upper part of the Fig, but gall-flowers at
the base. [The Caprificus, at Naples, bears three crops of inedible
Figs each year, viz. _Mamme_ (April), _Profichi_ (June), _Mamnoni_
(August). The ♂-flowers are produced especially in June, the first
Figs being almost entirely ♀, and the last having but few ♂-flowers.
Each crop produces a new generation of Fig-wasps. The female wasp
enters the Figs on the Caprificus, and lays one egg in each flower,
with the result that the flower developes into a kind of gall. The
mother-wasp dies within the Fig. The male wasp is wingless; it bites
a small passage into the ovaries containing the female wasps, and
impregnates them; the female wasps then escape from the Fig, those in
the _Profichi_ carrying pollen away with them as they pass out. They
then enter another Fig, lay their eggs, and die. The edible Fig-tree
similarly has three crops in the year, _Fiori di fico_, _Pedagnuoli_,
_Cimaruoli_. The wasps, entering these Figs, are unable to lay their
eggs in the ovary, but, nevertheless, they effect cross-pollination on
entering the _Pedagnuoli_, which bear fertile seeds.]~

The flowers of _Brosimum_ are the most reduced. The perianth
is wanting, and the ♂-flower has only 1 stamen. _Cecropia_
(Trumpet-tree), in S. Am., has its pith divided into chambers;
these are inhabited by ants, which feed upon small food-bodies
formed on the swollen base of the petioles. The leaves are
petiolated, often shield-like, fringed or lobed, and sometimes
with white felted hairs. They serve as food for _Bradypus_
(the Sloth). _Sorocea_; _Castilloa_.
