    3, —Raphides, Splicer aphides, Long Crystal Prisms, and Short Prismatic Crystals.—Their distinctive characters. Extensive researches resulting in the discovery of the importance of raphides as natural characters in systematic botany; affording a true distinction which is often more simple and available, fundamental and universal than any other single diagnostic; the raphides being constant and very easily found in the plant producing them, from its earliest state—even in the seed-leaves —and throughout its frame in all stages of its existence. Thus, for example, in our Flora, Balsaminaceae can be at once surely known from the other orders of Thalamiflorae, Onagracese from the other orders of Calycifiora?, and Eubiacese from the other orders of Corolliflorae; while, on the other hand, an order— Hydrocharidacese, e. (j.—may be as certainly distinguished by the want of raphides which abound in its allied orders (Various numbers of the Ann. Nat. Hist., 1861-65; Seemann's Journ. Bot., March 1864; Quart. Journ. Micros. Science, Jan. 1864, July 1865, and—how and were easiest found—ibid. July 1869 ; as natural characters in the British Flora, ibid. Jan. 1866; and in the Flora of the World, with epitome of the author's former observations, Popular Science Eeview, Oct. 1865; cells and raphides of Duckweeds and exraphidian character of Woljfia, with engravings, Seemann's Journ.
