the filaments slender, inflected in the bud ; anthers very small and globular', but 
with distinct parallel cells, opening longitudinally. Ovary conical in the centre. 
Fruit unknown.

I have some hesitation in describing the species without having seen the fruit, but it appears 
quite distinct from any other one known to me. — Benth. 
In his later writings, Baron Mueller merges E. Bowmani in E. siderophloia (see Eucalypt. 
Dec. 4), from which he says thfit it chiefly differs in the leaves being less shining and in the 
peduncles being broadly compressed, more sessile flowers with shorter operculums, and more 
twisted filaments. The bark and fruit still remains unknown. 
21. 22. Clceziana (after Professor Clcez), F. v. M. Fragm. xi. 44. A tree of 
about 80ft. in height with a dark fissured bark on the trunk, the branchlets 
slightly angular. Leaves chartaceous, ovate to elongate-lanceolate, 3 to 5in. long, 
f to If in. broad, deep-green on the upper, lighter on the under side, the primary 
lateral nerves joining the intramarginal one some distance from the edge of the 
leaf ; petioles slender, 4 to 8 lines long. Panicles lateral or terminal, much 
branched. Peduncles moderately stout, rather short. Pedicels somewhat thick, 
under the flowers, about If line long, unopen flower-bud globose-ovate, 2 lines 
long. Operculum depressed-hemispherical, stamens all fertile, indexed in the 
bud. Filaments very thin, capillary, white, about 4 lines long. Anthers * line, 
almost globose, slits longitudinal. Style about 2 lines long ; stigma not dilated. 
Young fruit semiglobose-turbinate 3 to 4-celled, not angular. Seeds not winged.

22. E. Howittiana (after A. W. Howitt), F. v. M. Wing's Southern Sci. 
Bee. ii. 171. and Eucalypt. Dec. 9. A tree attaining the height of about 100ft. 
and trunk diameter of 4ft., bark somewhat stringy. Branchlets angular. Leaves 
from ovate to elongate-lanceolate, 2 to 5in. long, f to lfin. broad, slightly curved, 
dark-green above, much paler beneath. The lateral nerves numerous, intra- 
marginal one near the edge ; petioles f to lin. long. Panicles If to Gin. long, 
axillary and terminal, their ultimate branches short, angular, bearing generally 
from 3 to 6 sessile flowers. Calyx-tube angular, very small, semiovate or semi- 
elliptical. Operculum almost membranous, about 2 lines long, acutely conical. 
Stamens all fertile ; filaments in the bud bent inwards towards the summit, 
nearly white. Anthers minute, cordate or reniform-globose, opening by longi- 
tudinal slits, their gland inconspicuous, cells ellipsoid, parallel, slits marginal. 
Style very thin, extending considerably beyond the calyx-tube. Fruit very small, 
ovate-globular, smooth and shining, hardly exceeding 2 lines long, truncate and 
narrow at the margin, 3 to 4-valved. Seeds very small, not winged.

Eucalypt. Dec. 4. Black Ironbark. “Wooroola,” Bundaberg, Keys ; “ Biggar,” 
Brisbane, T. Petrie. A tall tree, with a hard, persistent, rough, blackish, thick, 
deeply furrowed bark. Leaves ovate-lanceolate or lanceolate, much acuminate, 
straight or more frequently falcate, about 3 to Gin. long, often rather thick, with 
numerous fine diverging veins, the intramarginal one close to the edge. 
Peduncles axillary or in terminal corymbose panicles, more or less angular, each 
with about 6 to 12 flowers, on distinct angular pedicels. Calyx-tube shortly 
turbinate, about 2 lines diameter. Operculum conical or acuminate, rather 
longer than the calyx-tube in the ordinary form. Stamens 2 to 3 lines long, all 
perfect, outer filaments not inflected in the bud ; anthers very small and nearly 
globular, the cells very short, opening at first in oblong slits, extending at length 
to the base or sometimes almost confluent. Stigma not or hardly broader than 
the style. Ovary convex or conical in the centre. Fruit globular-truncate or
