Series II. Keterostemones. — Outer stamens anantherous or with small ahortice anthers : 
anthers of the perfect ones small, globular, or truncate, the cells contiguous, opening in pores or in 
oblong slits, sometimes at length confluent. 
(The species are all Eastern, one only tE. gracilis) extending also into Western Australia, and 
all extratropical, two only (E. h anna stoma and F.. microcorys ) also tropical or subtropical. 
Benth.) 
(The outer stamens appear also to be anantherous or with abortive anthers only in A. virgata, 
and perhaps occasionally but only in a slight degree in some others of the Renantherw, and 
sometimes but rarely in E. bicolor, amongst Poranthene, but I have never found them so in any 
of the other species. — Benth.) 
Umbels all axillary or lateral. Buds ovoid or rarely obovoid. Peduncles 
terete or nearly so. 
Flowers large, usually 3 to 5 in the umbel. Leaves very coriaceous . . 8. E. leucoxylun. 
Flowers small, 4 to 8 in the umbel. 
Leaves rather thin. Buds ovoid, often acuminate. Flowers distinctly 
pedicellate 9. E. melliodora. 
Leaves thick, narrow, black-dotted, mostly under Bin. long. Buds 
obovoid, tapering into short pedicels or nearly sessile 10. E. gracilis. 
Upper umbels forming a terminal corymb or panicle. Buds obovoid. 
Leaves thick, narrow, black-dotted, veins scarcely visible. Flowers 
small. Pedicels short 10. A', gracilis. 
Leaves rather thin, veins very oblique, often distinct. Flowers small. 
(Anthers usually all perfect) 18. E. bicolor. 
Leaves rather thick, not dotted, veins numerous and more regular but 
fine, sometimes indistinct. Flowers moderate-sized or rather large, 
distinctly pedicellate ' 11. A’, paniculata. 
Upper umbels forming a terminal corymbose panicle. Buds clavate, 
tapering into a rather long pedicel. 
Buds very angular. Operculum often conical 11. E. paniculata. 
Buds not angular. Operculum very short and obtuse. 
Leaves very coriaceous, with oblique veins. Fruit pear-shaped with 
a broad flat rim 12. A’, hamastoma. 
Leaves rather thin, with almost transverse veins. Fruit oblong . . 13. E. microcorys. 
Sekies III. Porantherse. — Stamens all perfect (except, rarely in E. bicolor and perhaps in 
E. polyanthemos) ; anthers small and globular, or broader than long, the cells distinct, opening in 
small circular pores, sometimes extending at length into oblong slits. 
(The leaves when narrow have always an oblique irregular venation. The operculum is short, 
and the capsule sunk in the fruit. — Benth.) 
(The anthers sometimes are very nearly those of the Micranthene, whilst among Micranthera 
there are several species, especially A. siderophloia, in which the anther-cells are so short that 
their slits are at first little more than pores. — Benth.) 
Umbels few-flowered, usually several together, in short leafless axillary or 
terminal panicles, or in terminal corymbs. Operculum short, obtuse. 
Leaves sessile, opposite, cordate or ovate. Flowers in terminal corym- 
bose panicles 14. A’, pruinosa. 
Leaves orbicular to broad-ovate, of an almost ashy hue or dull-greenish. 
Outer stamens sterile, fertile anthers truncate, opening by terminal pores 15. A’, polyanthemos. 
Leaves orbicular-ovate or roundish, very glossy. Stamens all fertile ; 
anthers roundish -ovate, opening below the summit by pores or short 
slits 10. A’, populifolia. 
Leaves thick, falcate or oblong-lanceolate, shining on both sides, nerves 
somewhat patent. Operculum sharply conical, about Jin. long. Fruit 
Jin. long and Jin. thick 17. A. ochrophloia. 
Leaves oblong or lanceolate, rather thin 18. A. bicolor. 
Umbels several-flowered, often solitary in the axils, the upper ones in 
terminal corymbose panicles. Operculum usually conical, about as 
long as the calyx-tube. Pedicels short. 
Leaves broad or falcate, very coriaceous 19. A’, hemiphloia. 
Leaves coriaceous, with numerous fine diverging veins, sometimes 
inconspicuous 23. E. siderophloia. 
Series IV. XVI ic rant her a;. — Anthers eery small, globular, or broader than long, with 
globular distinct cells opening in lateral slits. 
(Here are most of the “ Ironbarks.” The series, which closely connects the Borautherce with 
the Norinales, i3 by no means a distinctly marked one. The anthers have at first sight, in their 
shape and small size, the appearance of the former, whilst their dehiscence is almost or quite
