/fᵻˈlɒdʒn̩əs/, U.S.

/fəˈlɑdʒənəs/

Origin: Formed within English, by compounding. Etymons: phyllo- comb. form, -genous comb. form.

Etymology: < phyllo- comb. form + -genous comb. form. With sense 2 compare earlier phyllogen n. at phyllo- comb. form .R. G. Mayne (see quot. 1858 at sense 1) also gives a Latin form phyllogenus.

Botany.

1. Of a fungus: growing upon leaves. Now rare.

ΚΠ

1858 R. G. Mayne Expos. Lexicon Med. Sci. (1860) Phyllogenus,..that which grows upon leaves..: phyllogenous.

1913 F. L. Stevens Fungi which cause Plant Dis. 505 Pycnidia on a cobwebby subicle, phyllogenous.

2. Giving rise to leaves. Cf. phyllogen n. at phyllo- comb. form . rare.

ΚΠ

1903 Bot. Gaz. 36 472 Nĕmec has compressed the growing apices of shoots of Nepeta macrantha and studied the effect on the leaf primordia... In one experiment the phyllogenous tissue was extended beyond the normal.

3. Developing or originating from leaves.

ΚΠ

1974 Amer. Jrnl. Bot. 61 227/1 Besides phyllogenous and root-bud branching, Bower recognized three classes of acrogenous branching.

1982 Bot. Gaz. 143 322/2 Branching of the adult shoot occurs by the equal dichotomy of the apical meristem. No cauline or phyllogenous (leaf-borne) buds are produced.

1984 Amer. Jrnl. Bot. 71 51 Branching of Microlepia shoots is fundamentally dissimilar to the phyllogenous lateral branching of other dennstaedtioid ferns.
