I have modified the generic character so as to include the Tasmanian (and several Australian) species, which
have decidedly dehiscent capsules (as in Zygophyllnm), and of which one has filaments with broad lacerated wings,
and the other subulate filaments, and neither o f which have scales aU h e base of the ovary. Sepah persistent, and
p e ta ls four or five, the latter clawed. Stamens eight to ten, with subulate or winged filaments. Ovary on a raised
torus, obconical, with a subulate twisted style, four-celled; cells with two to six pendulous ovules in each. Capsule
membranous, obeuneate, four-lobed or four-winged, four-celled; cells one- or two-seeded, dehiscing doivn each
cell ; walls o f an outer gi-een herbaceous layer, and an inner thin wliite parchment. Seeds peudulom, one or two
ripening in each ceU.— Herbaceous, jointed plants, with opposite bifoliolate stipulate leaves, and axillaiy soUtary
yellow flowers. (Named in honour o f Professor Roper, o f Bale.)

There are more species o f th is Natu ral Order in Austraha than in any country o f equal area, except
I th e Cape o f Good H op e , which in th is respect presents a remarkable analogy w ith Australia.
M o st o f th e species, o f which there are upwards o f one hundred and sixty known, be long to th e tribe Boro-
niece, which is almost confined to th is continent. N ew Zealand contrasts remarkably with Australia in
th e rarity o f Butaceæ, which is le ss anomalous, because th e species prefer a dry chmate and soil. In company
with the Epacrideæ th e Boronias cover g fe a t heathy tracts o f land ; th ey diffuse a strong aromatic
odour.

This is an extratropical AustraUan genus, almost confined to the south coast, and chiefly to Bass’ Straits.
Tlieve are about twelve known species, the westernmost o f which inhabits King George’s Sound. One is found
near the tropic, on the east side of the continent. The species are extremely variable and difficult to detennine ;
some of the Tasmanian ones wiU probably he reduced. AH are shrubs or small trees, with opposite leaves, generally
densely woolly beneath.— Flowers solitary or few together, axillary or terminal. Calyx hemispheiical, truncate,
obscurely four-toothed, rarely with long segments. Corolla cylindrical, much longer than the calyx ; segments
generally united for nearly their whole length, with valvate, erect or recurved short apices, tomentose or pubescent
externally. Stamens eight, included or partially exserted. Capsule of four cocci, of which one or more are often
imperfect ; coccn two-valved, with a cartilaginous endocarp, one- or two-seeded. Seeds with a crustaceous testa, and
a straight slender embryo immersed in fleshy albumen. (Named in honour of Correa de Serra, an eminent Portuguese
botanist.)
