6 ANNALS OF THE EOYAL BOTANIC GARDEN, CALCUTTA.
in 3 series, nearly equal, usually orbicular, very concave. Stamens 6—21, imbricate in
2 or more series, broadly oblong, thick, fleshy ; anthcr-cells dorsal, obloug, connectives
produced. Ovaries 3—6; style short; stigma obtuse or capitate; ovules 6 to 8, on the
ventral suture. Ripe carpels globose or ovoid, stalked. Distrib.—Species 6, tropical
Asiatic.
A genus closely allied to Bocagea, St. Hilairc, but diSering from that in having its
sepals and petals much imbricate instead of valvate; in bearing more ovules, and more
seeds in its ripe carpels; in its anther-cells being moro lateral and not so entirely dorsal
as in Bocagea, and in the apical process of the connective being truncate. The flowers
of Siigeroea are small and the sepals and petals are very concave; and in these respects,
as well in the comparative fewness of the seeds in their ripe carpels, they diverge from
those of typical Uuarieco. Hooker Jîlitis and Thomson (in their Flora Indica), Bentham
and Hooker (in their Genera Pîantanmi), and Bâillon (in his Histoire des Plantes, Vol.
I . 202, 281) retain Sageroea as a genus,—an example which I would have followed
-without any hesitation had not Sir Joseph Hooker united it with Bocagea in bis
Plora of British India. The extreme imbrication both of the sepals and petals appears
to me, however, in spite of Sir Joseph Hooker's more recent view, so insurmountable
an argument against its reduction to a genus in which both these sets of organs are
very distinctly valvate, that I adhere to his earlier view that Sageroea should remain
distinct and take its place in the tribe XJvarieoe,

2 SAGEEÍEA LISTERI, King n. sp. A tree with pale, fibrous, deciduous bark; young
branches rather slender, pale; all parts, except the flower and ripe fruit, glabrous.
Leaves coriaceous, elliptic-oblong to elliptic, shortly acuminate, the base cunéate or
rounded; upper surface shining; the lower dull, darker than the upper when dry; main
nerves G to 8 paii-s, curved, spreading, very faint; length 3-75 to 5-5 in., breadth 1'5 to
3-5 in.; petiole '4 in. Flowers sub-globular, solitary, axillary, sessile, -3 in. in diam.;
bract 'close to flower, sub-orbicular, pubescent outside. Sepals much imbricate, very
concave, orbicular, whitish, pubescent outside, glabrous inside, -15 in. in diam. Petals
like the sepals, but larger and more densely pubescent outside; the inner row rather
smaller than the outer. Stamens 9, the connective broad, flattened, not produced at
the apex; anther-cells lateral, extrorse. Ovaries (not seen). Ripe carpels broadly ovoid,
nan-owed to the base, minutely pubescent, 1 in. long. Seeds about 12, in two rows,
flattened.

This closely resembles S. elliptica, but has smaller leaves with fewer nerves and
fewer stamens; while the carpels are ovoid, not globose. Its timber is said to be of
excellent quality.
