The fruit is a berry,unlike the majority of the families of this order. Here belongthe asparagus, the false and true Solomons seal, Indian cucum-ber, Trill in 111, and the closely related Smilax, etc. The Lilvfamily includes nearly one half of the members of the order and.

Theflowers are large and of the Erythronium type. Here belongsome of the most showy of our native and cultivated plants; theday lily, Erythronium, tulips, hyacinths, lilies, Fritillaria, onion,aloes and Spanish bayonets (Yiicca) of arid regions. Amongthe higher genera of the lily family the organs of the perianthoften cohere, forming a tubular structure. In the Amaryllisfamily we find the same type of flower and fruit as in the lilyfamily, but the basal growth of the receptacle has enveloped theovary so that the flower has become epigynous (Fig. 289, A).
