† raphidianadj.

1849 J. H. Balfour Man. Bot. § 18 It has been said these crystals [sc. raphides] exist also in the intercellular spaces; but this seems to depend on the mode in which the section of the plant was made, for when raphidian cells..are situated close to a lacuna, the crystals may easily be pushed into it accidentally by the knife.

1872 Amer. Naturalist 6 244 Mr. Gulliver showed the great importance of plant-crystals, especially raphides, in systematic botany; the raphidian character being..so much more fundamental and general than other single diagnostics.

1876 Encycl. Brit. IV. 89/1 The Squill bulb and the bulb of the Onion exhibit raphidian cells, which are easily separated during the decay of the plants.
