The Bornean genus Bihnnia has nine petal- loid sterile stamens, and the three stamens of the third row fertile and extrorse; the anthers are said to have four cells instead of two. The anthers are also four-celled in Mespilo- daphne; but the whole nine outer stamens are fertile, as in Oreodaphne, and the woody sac, varying in its depth and in the height to which it surrounds the fruit, has a thick, single or double, truncate rim. Mespilodaphne may then be considered as Cryptocarya, with anthers that open by four Fia. 249. Diagram. Fl&. 250. Fruit. III. OCOTEA SEEIES. Ocotea} (fig. 260) has nearly the floral organization of Cinnamomuni, and is only distinguished therefrom by a set of characters that would appear of slight importance in themselves in any other order. But these characters, taken together, may be made to suffice for the foundation of an artificial series such as is especially useful in the study of so homogeneous a family as this. The concave receptacle, the perianth androceum and gynseceum, are in some species analo* gous to the same parts in Cinnamomum. But the staminodes (of the fourth whorl) are quite absent in certain species, or when not quite absent are reduced to little sessile scales. The flowers are sometimes herma- phrodite, but are more frequently, nay, nearly always, 1 AuEL., Ouian., ii. 780.—J,, Oen., 80.— viii. 46; Sijst., 355.—Endl., Gen., n. 2048.— Nebs, Syst., 354, 371 (part.).—Ehdi., Gen,., Svonymodapltne Nees, Syst., 244, 263.—Endl., n. 2054.
