“PHANEROGAMIA, 
OR 
FLOWERING PLANTS: 
Prants with flowers furnished with special organs of reproduction 
(stamens and pistils), and producing seeds containing an embryo 
previous to germination. 
Crass I.—DICOTYLEDONS. 
Herbs, shrubs, or trees, which have a stem formed of concentric 
layers: a cellular pith in the centre; then one or more layers of 
elongated cells intermixed with vessels; the whole surrounded by 
a separable bark or rind, having elongated cells on the inner and 
ordinary short cells on the outer side. 
Seed containing an embryo having two opposite seed-leaves or 
cotyledons, between which lies the bud which is to form the future 
stem. 
Leaves with branched anastomosing veins. Parts of the flower 
generally 5, or 4, or some multiple of these numbers. Calyx and 
corolla generally unlike in texture. 
Suzp-Crass I.—POLYPETALA THALAMIFLORA. 
Calyx almost always free from the ovary. Sepals distinct, very 
rarely united. Torus small or elongated, very rarely expanded 
into a thick fleshy disk. Petals in 1 or 2 whorls, unlike the 
sepals, or in 2 or more whorls passing gradually into sepals, 
inserted on the torus, or rarely into the very bottom of the calyx, 
and united at the base of the staminal whorls (abnormal or even 
wholly absent in a few cases). Stamens commonly but not always 
indefinite, inserted into the torus, or more rarely adhering to the 
base of the calyx, or that of the petals. Ovary superior, or rarely 
immersed in an enlarged fleshy torus.
