The females, less numerous at the summit of the common peduncle, may even be solitary.^ III? ALANGIUM SERIES. The flowers of .ikwg'mm ^ (fig. 245-252) are regular and herma- phrodite. The concave receptacle, like that of Combretum or Nyssa, ' According to Bentham and Hookee, N. sessiliflora HooE. P. and Thoms., a Himalayan species, is very analogous to Ceratostachya (Bl. mjdr. 644 ;—Mia. Fl. i. p. i. 839), a Javanese plant, itself prohahly identical with AgathisantAes (Bl. he. cit.;—Miq. loc. eit, 838),. Oamptotheea, of Tihet, appears very near the preceding types, differing chiefly in its valvate corolla (imbricate in Ceratostaehys) and in its anthers with four cellules pendent from a dila- tation of the connective, and opening irregularly on the side of the filament. 2 Here also we provisionally place JDavidia, a beautiful tree of Tibet, the authentic specimens of which, unfortunately, some time since disap- peared from the herbarium of the Museum, which has prevented us from giving a figure of it. The flowers are collected in 1- or 2-sexual capitules ; the males represented simply by stamens, free on the surface of a globular recep- tacle. The female flower, occupying, when present, not the summit, but the side of the upper portion of the receptacle, is composed of an inferior ovary, with numerous uniovulate cells, surmounted by an epigynous calyx, within which may be found some short stamens with fertile or sterile anthers. The ovules in each cell are solitary and descending, with exterior mi- cropyle. D. involucrata has alternate leaves and two large white foliaceous bracts under the inflorescence.
