Contains 5 genera and about 40 species, natives of tropical America, shrubs, distinguished by the peculiar pitcher-like bracts which often subtend the flowers. In Marcgravia the flowers have the further peculiarity that the corolla is united in one piece (gamopeta- lous) which falls off like a cap. The sta- mens are usually numerous, the ovary 1- celled, becoming capsular in fruit. Family Quiinaceae. Quiina Family. A small and unimportant South American family of trees, consisting of two genera and 19 species. Family Theaceae. Tea or Camellia Family. Contains about 16 genera and 160 species, rather widely distributed. They are trees or shrubs with large regu- lar flowers having usually 5 imbricated sepals, 5 petals, numerous hypogynous stamens and a 2-oelled ovary, becoming in fruit a woody capsule. The • representatives of this family in our territory are shrubs of great beauty, when in bloom, their large, solitary white flowers suggesting single roses. There are two genera, Stuartia and Gordonia, both natives of the Southern States, the latter known as the loblolly bay. But it is the genus TJiea (including Camellia) which lends great commercial importance to the family. The genus consists of about 16 species of shrubs, con- fined in the wild state to India, China an,d Japan, but cultivated in many parts of the world. The flowers are large and handsome, and are succeeded by S-valved capsules, two of which are shown in the illustra- tion (Fig. 155). The process of drying the tea l
