bifoveolate. Stamens 9 to 10, opposite the sepals, alternate with the petals. 
Anthers exappendiculate, dorsifixed, nearly ^ line long. Styles 2, free, setaceous, 
stigma terminal, very small, glabrous, almost 2 lines long. Ovary hoary- 
velvety, semisuperior, septicidal, 2-celled, ovules few. — F. v. M., l.c.

8. SPIRSANTHEMUM, A. Gray. 
(Flowers somewhat resembling those of Spircea.) 
Flowers hermaphrodite or polygamo-dioecious, calyx-tube short, free, the limb 
4 to 5-parted ; lobes ovate-triangular, persistent, valvate. Petals none. Stamens 
4 to 5 or twice that number, inserted at the base of the calyx, nearly hypogynous, 
long as the calyx ; filaments filiform ; anthers didymous. The hypogynous 
glands between the stamens and the ovary, 8 to 10, linear. Carpels in 
the male flowers none, in the female flowers 4 or 5, rarely 2 or 3, free, 
oblong-ovoid, very much attenuated, style stigmatose at the apex ; ovules 1 to 5 
or numerous, 2-serrate. Follicles 2 to 5, twice the length of calyx, compressed, 
dehiscent inwards, 1 or 2-seeded. Seeds oblong, compressed. Testa winged 
above or on both sides, embryo sub-cylindrical, albuminous. — Shrubs or small 
trees with terete branchlets. Leaves opposite or verticillate, petiolate, simple, 
oval or oblong, entire or serrate. Stipules deciduous. Flowers numerous, 
disposed in axillary panicles, small, on articulate pedicels. — B. and H., Gen. PI. 
i. 650. 
1. S. Davidsonii (after Alex. Davidson), F. v. M., Austr. Journ. of Phar., 
March 1887. A spreading-headed tree with slender stem, about 25ft. in height, 
the branchlets glabrescent. Leaves opposite, on rather long petioles, glabrous on 
both sides, prominently costate-nerved beneath, foveolate at the axils of the 
nerves. Panicles terminal, erect, ample. Flowers numerous, pinkish-white ; 
peduncles and pedicels slightly downy. Segments of the calyx ovate-lanceolate, 
glabrous, stamen exserted, twice as many as divisions of the calyx ; hypogynous 
scales very minute. Follicles 2 to 3, considerably longer than the calyx. Seeds 
with a terminal appendage. — F. v. M., 1 c. 
Hab.: On the highest crest of one of the mountains of the Bellenden Ker Range, Sayer and 
Davidson (F. v. M.) 
Baron Mueller also notes that this species is closely allied to S. samoense, but that plant, so 
far as known, differs in its leaves being more rounded, copiously dentate, a closer nervature, 
shorter stamens and styles, as well as in its greater number of carpels. From S. vitiense our 
plant is separated by always simply opposite leaves, terminal inflorescence, longer pedicels, 
larger flowers, much exserted stamens and carpels, not several times longer than the calyx. 
S. Macgillivrayi , from the New Hebrides, is as yet imperfectly known, but the leaves are 
described as serrate and the flowers as always tetramerous. S. Graefferi and S. Katakata, from 
Fiji, are also allied but not identical. The New Caledonian congeners are still more distinct. 
9. DAVIDSONIA, F. v. M. 
(After J. E. Davidson.) 
Calyx 4 to 5-fid, {estivation valvate. Petals none. Stamens 8 to 10, hypogy- 
nous. Filaments free, setaceous. Anthers dorsifixed, oblong, 2-celled, dehiscing 
longitudinally. Styles 2, setaceous, free. Stigmas very small, terminal. Berry 
oblong-oval, 2J to 3in. long, 2 to 2Jin. diameter. Epicarp purple, but covered 
by a loose covering of short brown hairs ; pulp deep-red, very juicy. Seeds 
usually 2, flattish, about 8 or 9 lines broad, bordered by a rather deep irregularly 
laciniate wing, exalbuminous. Cotyledons plano-convex, straight, ovate. Radicle 
very short, superior. — Small erect trees with large very irregularly toothed impari- 
pinnate stipulate leaves, young growth more or less hairy. — F. v, M. Fragm.
