Tetrathyrium.'] hamamelideje. 133 



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

 tlie inflorescence. Leaves alternate, ovate, or broatUy elliptical, 3 to 4. in. 

 long, shortly acuminate, entii'e or with a few minute distant glandular teeth, 

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

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

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

 solitary, globidar, 4 or 5 lines diameter, slightly hoaiy, with a i<i\\ minute 

 linear entii'e or fringed bracts under the flowers. Flowers about 20, closely 

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

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

 door-like valves, as in Hamamells. 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 Eustic/ma, 

 but differs in the sestivation of the calyx and in the form of the petal-scales, stamens, and 

 styles. 



5. DISTYLIUM, Sieb. and Zucc. 



Sepals 3 to 5, fi'ce, unequal, imbricate in the bud. Petals none. Stamens 

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

 2-celled, wdth 1 pendidous (or laterally attached?) ovide in each cell. Styles 

 2, subidate. Capside ovoid or oblong, the carpels separating at the top, and 

 opening in 2 valves. — Trees or slu'ubs. 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 UamameHdeic, which it resem- 

 bles in other respects. 



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

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

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

 riaceous. Eacemes |- to 1 in. long, the upper flowers hennaphrodite. Sepals 

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

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

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

 immatm-e in om* specimens, but they appear to have veiy little albmnen 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. UMBELLIFER^. 



Calyx combined with the ovaiy, either eutii-ely so or sho\dng 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-ceUed, with one pendidous ovule in each cell. Styles 2, with terminal 

 stigmas. Fruit separating into 2 indehiscent diy caii)els resembling seeds 

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

 Each cai-pel marked outside ^\\i\\ 10, 5, or fewer prominent ribs, and under- 

 neath or within the pericaqDs are often longitudinal oil receptacles called
