[NL., ένδον , within, + κύημα , an embryo ( κυεῖν , con- ceive), + -atel.] In embryol ., developed in the manner characteristic of reptiles, birds, and mammals, in which the embryo is bodily inva- ginated in an involution of the blastodermic membrane, and an amnion is developed in con- sequence; amniotic and allantoic, as verte- brates above batrachians: opposed to epic ye- mate. stem which has ordinarily no dis- tinct i on of pith or bark, and in cro section shows the bundles irregularly dis- posed, either scat- tered over the whole surface or gathered more compactly toward the circumfer- ence.

If there is no ectocyst, the endo- derm forms the entire integument. (b) In Poly- zoa , the proper ectodermal layer of the organ- ism inside the hard ectocyst, together with the parietal layer of the mesoderm which lines and secretes the cells of the exoskeleton. See cut under Plum a tell a . endoderm (en dō-derm), n. [ ένδον , within, + δέρμα, skin.] In zool ., the completed inner layer of cells in all metazoan animals, formed by the cells of the hypoblast or endoblast, and representing, under whatever modification, the lining of the enteron: opposed to ectoderm. Primitively, it is the wall of the gastrular body-cavity, as the ectoderm is that of the whole body. Also entoderm. See cut under Hydrozoa . The inner, or endoderm , is formed by the "invagination" of that layer into the space left void by the di olution of the central cells of the " "morula.'

[ ένδον , with in, + γάμος, marriage.] Marriage within the tribe: a custom among some savage peoples: opposed to exogamy . The rule which declares the union of persons of the same blood to be incest has been hitherto unnamed. The words endogamy and exogamy (for which botanical science affords parallels) appear to be well suited to ex- pre the ideas which stand in need of names, and so we have ventured to use them. McLennan , Prim. Marriage, iii., note. Evidently endogamy , which at the outset must have characterized the more peaceful groups, and which has comitant of the higher forms of the family. The leaves are generally paral- lelveined, the flowers usually have three organs Parts of an Endogen. tyledon, and the radicle i ues from a sheath and is never developed into a tap-root in germination. The endogens are divided into 34 natural orders, including about 1,500 genera and from 18,000 to 20,000 species. By the characters of the in- florescence they are also distinguished as either spadi- ceo us, as in the Palmæ and Araceæ , petaloideous, as in the Orchid aceæ, Liliaceæ , Iridaceæ , and Amaryllid aceæ , or glumaceous, as in the Gramineæ and Cyperacea . These 8 orders embrace over four fifths of the whole number of species, the Orchid aceæ alone including nearly 5,000. This cla contains many of the most valuable food-producing plants of the vegetable kingdom, such as the cereals and The structure of the roots of endogens and exogens is e entially the same in plan with that of their respective stems.
