Tetrathyrium.'] hamamelide^e. 133 



1. T. subcordatum, Benth., n. sp. A shrub of 3 ft., glabrous except 

 the inflorescence. Leaves alternate, ovate, or broadly elliptical, 3 to 4. in. 

 long, shortly acuminate, entire or with a few minute distant glandular teeth, 

 broadly and slightly cordate at the base, rather thick, with prominent pinnate 

 veins, on petioles of 3 to 6 lines. Peduncles axillary, solitary, 2 or 3 lines 

 long, with a few small fringed scales or bracts at the base. Flower-heads 

 solitary, globular, 4 or 5 lines diameter, slightly hoary, with a few minute 

 linear entire or fringed bracts under the flowers. Mowers about 20, closely 

 sessile, small. Calyx-lobes lanceolate, about 1 line long. Stamens rather 

 shorter ; the anthers nearly square; crowned by long points, with 4 persistent 

 door-like valves, as in Hamamelis. Styles glabrous, shorter than the* stamens. 

 A bush, once seen on the Black Mountain, Wilford, from which we have several speci- 

 mens, but it has not been received from any other collector. It has the habit of Eustigma, 

 but differs in the aestivation of the calyx and in the form of the petal-scales, stamen9, and 

 styles. 



5. DISTYLIUM, Sieb. and Zucc. 



Sepals 3 to 5, free, unequal, imbricate in the bud. Petals none. Stamens 

 2 to 8 ; anthers oblong, opening longitudinally. Ovaiy superior, 2-lobed, 

 2-celled, with 1 pendulous (or laterally attached ?) ovule in each cell. Styles 

 2, subulate. Capsule ovoid or oblong, the carpels separating at the top, and 

 opening in 2 valves. — Trees or shrubs. Flowers polygamous, in short ax- 

 illary racemes. 



A small Asiatic genus, whose affinities have not as yet been satisfactorily established. The 

 superior ovary scarcely admits of its being retained among Hamamelidece, which it resem- 

 bles in other respects. 



1. D. racemosum, Sieb. and Zucc. Fl. Jap. i. 178, t. 94 ? A glabrous 

 shrub. Leaves alternate, narrow-oblong, obtuse or somewhat acute, 1^ to 

 %\ in. long, narrowed at the base into a petiole of 3 to 5 lines, thickly co- 

 riaceous. Racemes j to 1 in. long, the upper flowers hermaphrodite. Sepals 

 about 1 line long. Anthers exserted, oblong, red, fully 1 line long. Ovary 

 short, the styles at least 3 lines, and both covered with stellate hairs. Male 

 flowers smaller, sessile, with shorter stamens. Young capsules ovoid. Seeds 

 immature in our specimens, but they appear to have very little albumen and a 

 large embryo. 



Hongkong, Champion, Wright, Wilford. Also in Japan, if the species be, as I believe 

 identical. I have not, however, seen the Japanese specimens. 



Order LI. UMBELLIFEILffi. 



Calyx combined with the ovary, either entirely so or showing a minute 

 border round the summit, with 5 small teeth. Petals 5, inserted round an 

 epigynous disk. Stamens 5, alternating with the petals. Ovary inferior, 

 2-celled, with one pendulous ovule in each cell. Styles 2, with terminal 

 stigmas. Fruit separating into 2 indehiscent dry carpels resembling seeds 

 (called mericarps), usually leaving a filiform axis either entire or split into two. 

 Each carpel marked outside with 10, 5, or fewer prominent ribs, and under- 

 neath or within the pericarps are often longitudinal oil receptacles called
