phylloidadj.n.

Brit.

/ˈfɪlɔɪd/, U.S.

/ˈfɪˌlɔɪd/

Origin: A borrowing from Greek, combined with an English element; modelled on a Latin lexical item. Etymons: Greek ϕύλλον , -oid suffix.

Etymology: < ancient Greek ϕύλλον leaf (see phyllo- comb. form) + -oid suffix, after post-classical Latin phylloideus ( C. F. Brisseau de Mirbel Élémens de physiologie végétale (1815) II. 624). Compare French phylloïde , adjective (1815 in the same source), post-classical Latin phyllodes (1813 or earlier), German Phylloid , noun (1873 in the passage translated in quot. 1875 at sense B.).In quot. 1858¹ at sense A., Mayne perhaps misinterpreted de Mirbel's French form as Latin.

Chiefly Botany.

A. adj.

Resembling a leaf; having parts resembling leaves. Also: derived from a leaf.

1858 R. G. Mayne Expos. Lexicon Med. Sci. (1860) Phylloides,..applied by Mirbel to parts which have the form of leaves, that is, which are flattened and herbaceous, as the stem of the Cactus phyllanthus: phylloid.

1858 R. G. Mayne Expos. Lexicon Med. Sci. (1860) at Phyllosoma A crustaceous animal with phylloid or bladder-like sacs attached to the hinder part of the body.

1917 J. W. Harshberger Text-bk. Mycol. & Plant Pathol. xxvii. 333 Chorisis, the separation of a leaf or phylloid part into more than one.

1956 Amer. Jrnl. Bot. 43 452/2 Provided that pistils are megasporophylls and stamens microsporophylls, as many botanists accept, all semaphylls, including petaloid staminodia..are strictly of phylloid origin.

1993 E. N. K. Clarkson Invertebr. Palaeontol. & Evol. (ed. 3) viii. 241/1 This is Order Phylloceratida, an almost smooth-shelled group with a characteristic ‘phylloid’ suture.

B. n.

Botany. An organ resembling a leaf in form and function, though not considered homologous with a true leaf; a leaflike structure in an alga.

1872 Bull. Torrey Bot. Club 3 36 You will observe that..the leaves are finely serrulate, while the phylloids are smooth and have entire margins.

1875 A. W. Bennett & W. T. T. Dyer tr. J. von Sachs Text-bk. Bot. 211 For the sake of finding an expression for these relationships in Algæ..the leaf-like appendages might be termed Phylloids [Ger. Phylloiden], the root-like appendages Rhizoids.

1932 P. A. Rydberg Flora Prairies & Plains Central N. Amer. 54 Sagittaria L... Leaves long-petioled with a sagittate or lanceolate blade or, especially the earlier ones, reduced to bladeless phylloids.

1965 P. Bell & D. Coombe tr. Strasburger's Textbk. Bot. (new ed.) 67 To distinguish them from the true leaves, stems and roots of the Cormophyta, all showing a very much more complex anatomy, these organs are referred to respectively as phylloids, cauloids and rhizoids.

1992 Internat. Jrnl. Plant Sci. 153 s40 (caption) Caulerpa prolifera branch with cauloids, rhizoids, and phylloids, the right one proliferating subapically.
