Properties. See Smilax.—The Ripogonum parviflorum of R. Brown [Allan Cunningham, In Hooker's Companion to the Botanical Magazine, vol. ii.], a native of New Zealand, where it is called kareao, is said to possess virtues similar to those of sarsaparilla, und may be termed the New Zealand sarsaparilla. The stems yield 12 per cent. of extract, which is bitter, and contains starch-gum and traces of astringent matter. [See a paper, by the author, in the Pharmaceutical Journal, vol v. p. 73.]
