flattened summit of the receptacle. The ovaries taper into a 

 hooked style, with a stigmatiferous apex, and contain a nearly 

 basilar ascending ovule with the micropyle downwards and outwards. 

 The flower is borne on a peduncle, which, like that of Chimonanthua, 

 bears imbricated bracts all over its surface ; they are analogous to 

 sepals, and become shorter as they are lower down. Here they are dis- 

 tichous, thick, and scarious. In other species, such as 0. lanccolala' 

 and laiirifolia,- these scales do not occupy the whole length of the 

 peduncle, but are massed together near its base, to which they form 

 a sort of sheath or involucre. The form of the perianth is here 

 somewhat modified. The flower-bud, nearly globular in 0. lanceolata, 

 becomes elongated in 0. laurifolta, chiefly through the conformation 

 of the petals. The stamens and carpels are numerous in the latter 

 species. Four or five^ species of Oxandra'' are known — shrubs from 

 the Antilles and the north of South America, with alternate entire 

 leaves, and a fruit consisting of a variable number of one-seeded, 

 shortly stipitate berries. 



B. Unune.e. — This secondary group is named after the genus 

 TJnonay which difiers from Uvaria in one essential point only : the 

 fact that its corolla is valvate, not imbricate, in aestivation. In all 

 else the flowers of that section of the former genus termed Pseado- 

 TJnond are perfectly similar to these latter — the trimerous calyx ; 

 the nearly equal, sessile, flattened petals spreading on the expansion 

 of the flower ; the indefinite stamens inserted in a spiral, and each
