Origin: A borrowing from Greek, combined with an English element. Etymons: phyllo- comb. form, Greek βράγχια.

With phyllobranchial adj. at Derivatives compare earlier phyllobranchiate adj. and the French parallel cited at that entry.1851 S. F. Baird tr. J. G. Heck Iconogr. Encycl. II. Zool. 77 The group which Latreille named Phyllobranchia, had already been provided with a name.

1880 T. H. Huxley Crayfish v. 271 The prawn's gills are..phyllobranchiæ;..the central stem of the branchia..bears only two rows of broad flat lamellæ.

1893 T. R. R. Stebbing Hist. Crustacea xvi. 221 In Sergestes, Professor Smith remarks, the branchiæ are compound phyllobranchiæ, while those of Penæus in the preceding family are compound trichobranchiæ.

1963 G. A. Kerkut Borradaile & Potts's Invertebrata (rev. ed.) xi. 412 The gills are of the kind known as phyllobranchiae... The axis of each..has on either side a row of plates, set close like the leaves of a book.
