holl. 1. p. 74. t. 100. T. buxifolia, Sieb. pl. exsic. nov. holl. 
no. 122. Leaves 4 lines long, and 3 lines broad. Umbels 
much crowded, small, 8-10-rayed. 
Ovate-leaved Trachymene. Shrub. 
Cult. All the species of Trachyméne will grow well in a 
mixture of loam, peat, and sand; and they may be increased by 
cuttings, under a hand-glass, or by seeds. 
VIII. ASTRO’TRICHA (from aozpor, asiron, a star, and 
Opik rpexoc, thrix trichos, a hair; in allusion to the starry down 
on the outside of the petals). D. C. coll. mem. 5. p.29. t. 5. 
and 6. prod. 4. p. 74.—Bolax species, Sieb. 
Lin. syst. Penténdria, Digynia. Tube of calyx ovate; 
limb small, hardly 5-toothed. Petals oval, acutish (f. 58. 6), 
permanent, flat, velvety from stellate down on the outside. 
Styles 2, filiform (f. 58. c.), not gradually thickening to the base. 
Fruit crowned by the calycine lobules and petals; mericarps 
ovate-oblong, contracted at the commissure; ribs very blunt, 
hardly prominent: of the primary ones there are 3 dorsal, and 
2 marginal, which are more acute and not so evident: of the 
secondary ones 4; vittæ wanting on the back, but there are 2 
rather prominent ones in the commissure, which are covered by 
a spongy pellicle.—Australian, branched subshrubs, having 
the branches, petioles, under side of leaves, and umbels beset 
with white stellate hairs. Peduncles panicled, each ending in a 
simple, many-flowered umbel. Bracteas under the branches 
and branchlets solitary. Leaves of involucrum few and linear. 
Habit almost of Hérmas, but the fruit is very different. It dif- 
fers from Bolax in habit, and in the fruit not being tetragonal.
