microarpa. The nuts are known in commerce as Corosso

[1913 Webster]
Vegetable kingdom (Nat. Hist.), that primary division of
living things which includes all plants. The classes of
the vegetable kingdom have been grouped differently by
various botanists. The following is one of the best of the
many arrangements of the principal subdivisions.
[1913 Webster] I. Phaenogamia (called also
Phanerogamia). Plants having distinct flowers and true
seeds. [ 1. Dicotyledons (called also Exogens). --
Seeds with two or more cotyledons. Stems with the pith,
woody fiber, and bark concentrically arranged. Divided
into two subclasses: Angiosperms, having the woody fiber
interspersed with dotted or annular ducts, and the seeds
contained in a true ovary; Gymnosperms, having few or no
ducts in the woody fiber, and the seeds naked. 2.
Monocotyledons (called also Endogens). -- Seeds with
single cotyledon. Stems with slender bundles of woody
fiber not concentrically arranged, and with no true bark.]
[1913 Webster] II. Cryptogamia. Plants without true
flowers, and reproduced by minute spores of various kinds,
or by simple cell division. [ 1. Acrogens. -- Plants
usually with distinct stems and leaves, existing in two
alternate conditions, one of which is nonsexual and
sporophoric, the other sexual and oophoric. Divided into
Vascular Acrogens, or Pteridophyta, having the
sporophoric plant conspicuous and consisting partly of
vascular tissue, as in Ferns, Lycopods, and Equiseta, and
Cellular Acrogens, or Bryophyta, having the sexual
plant most conspicuous, but destitute of vascular tissue,
as in Mosses and Scale Mosses. 2. Thallogens. -- Plants
without distinct stem and leaves, consisting of a simple
or branched mass of cellular tissue, or reduced to a
single cell. Reproduction effected variously. Divided into
Algae, which contain chlorophyll or its equivalent, and
which live upon air and water, and Fungi, which contain
no chlorophyll, and live on organic matter. (Lichens are
now believed to be fungi parasitic on included algae.]
[1913 Webster]
Note: Many botanists divide the Phaenogamia primarily into
Gymnosperms and Angiosperms, and the latter into
Dicotyledons and Monocotyledons. Others consider
Pteridophyta and Bryophyta to be separate classes.
Thallogens are variously divided by different writers,
and the places for diatoms, slime molds, and stoneworts
are altogether uncertain.

Vocabulary.
