Finally, in tins genus, as in most of this order, there are species 

 whose flowers are normally diclinous, such as U. Biirahol Bl.,' which 

 some authors have made the type of a special section, under the 

 name of Stelecliocarpus. Owing to the want of a gyna^ceum to the 

 male flowers, the receptacle is covered with stamens to the very 

 summit, and elongates into a cylinder with a conical end.- 



Thus marked out, consisting of nine secondary groups,^ which we 

 consider as only subgenera whose limits are not well defined, the 

 genus Vvaria contains half a hundred species, of which about four- 

 fifths belong to the Old World ;' the rest come from the United 

 States, Mexico,* and the north-west of South America." 



Sagerad' consists of trees from tropical Asia, of which the herma- 

 phrodite, or diclinous flowers are closely analogous to those of 

 Uvaria, The calyx consists of three pieces, united for a certain 

 extent, and imbricated in the bud ; and the corolla is double, with 



156, t. 20 ; B. H., Gen., 23, n. 5), specimens of 

 which are rare in herbariums, that at Kew being 

 probably the only one as yet known. According 

 to the description given by the above author, 

 S. insignis is a shrub from Borneo, with enormous 

 alternate sessile leaves, cordate at the base, has 

 flowers of an orange colour, with a globular re- 

 ceptacle ; sepals three, large, orbicular, rigid, 

 membranous ; petals six, spathulate, in two 

 verticils, imbricate (?) ; stamens indefinite, cunei- 

 form, connective dilated and truncated above 

 the cells; carpels indefinite (3-15), ovary sur- 

 mounted by a very short obtuse style, and con- 

 taining two (?) ventral ovules. The fruit is as 

 yet unknown. Despite the external differences 

 of size and form presented by the flowers and 

 leaves of this plant, is it quite certain that it 

 should constitute the type of a genus distinct 

 from Uvaria ? It is even possible that by its 

 carpels, described as containing two superposed 

 ovules, it becomes intermediate between the 

 pluriovulate Uvarias and Ellipeia (see Adan- 

 sonia, viii. 305, 336).

'^ The stamens are very numerous, formed like 

 those of most Uvarias, and nearly sessile. The 

 petals are glabrous and very concave. The 

 gynajceum of the female flower is like that of 

 a Magnolia on a small scale. The carpels are 

 numerous, short, covered with stilf hairs. The 

 style dilates rapidly and is divided into two 

 lobes, as in many true Uvarias. The ovules are 



Uvaria.

few in number ; there are only two or three in 

 each row. The fruit is borne on a long thick 

 peduncle. Miquel also refers U. Montana Bl. 

 to this group {op. cit., 21).
