Family Liliacese.—The relationship between genera, as between trillium, ervthronium, and lilium, brings us to a still higher order of relationship, where the limits are broader than in the genus. Genera which are thus related make up the family. In the case of these genera the family has been named after the lily, and is the lily family, or Liliacea:. 935. Order, class, group. — In like manner the lily family, the iris familv, the amar^Ilis family, and others which show characters of close relationsliip are united into an order which has Ijroader limits than the familv.
