Taxonomy

Genera

Acacia

Trees, shrubs, rarely herbs, often prickly or spinose. Leaves bipinnate; leaflets small and numerous or leaves reduced to phyllodes; petiolar glands often present; stipules generally spinescent. Inflorescence cylindric spike or globose head; peduncle solitary axillary or fasciculate or paniculate at the end of branches; bracts often two, scale like, situated on the peduncle at various levels. Flowers small, 3-5-merous, bisexual or plants polygamous. Calyx campanulate, dentate, lobed or polysepalous. Petals usually more or less united, rarely absent. Stamens indefinite, free or shortly and irregularly connate at the base; anthers small, eglandular. Ovary sessile or stipitate, with 2 or more ovules. Fruit ovate to linear, straight, arcuate or contorted, membranous to woody, rarely articulated or moniliform. Seed large, with a filiform funicle or fleshy aril.^[1] [more]

At least 2,930 species and subspecies belong to the Genus Acacia.

Acaena

Acaena is a genus of about 100 species of perennial herbs and subshrubs in the Rosaceae, native mainly to the Southern Hemisphere, notably New Zealand, Australia and South America, but with a few species extending into the Northern Hemisphere, north to Hawaii (A. exigua) and California (A. pinnatifida). [more]

At least 573 species and subspecies belong to the Genus Acaena.

Acantholimon

Shrublets, usually thorny, pulvinate, often subglobose, many-branched. Leaves borne on current year's branches, crowded, sessile, persistent on old branches after withering; spring leaves at base of current year's branches and similar or different from summer leaves; leaf blade linear, linear-needlelike, or linear subulate, usually very shallowly obdeltate to subcomplanate in cross section, apex usually pointed to awned. Inflorescences borne in axil of spring leaves at base of current year's branches, branched or unbranched; spikes pedunculate, with 2--8 spikelets, arranged in 2 rows, sometimes rachis undeveloped with spike or spikelets axillary; spikelets 1--5-flowered; bracts distinctly shorter than bractlet of first flower, margin membranous; first bractlet similar to bract, margin broadly membranous. Calyx funnelform or rarely subtubular; tube straight or occasionally basally oblique, inconspicuously herbaceous along ribs and scarious between ribs; limb purple, pink, or white, broad, scarious, 5- or 10-lobed. Corolla slightly exserted from calyx; petals basally slightly connate. Stamens adnate to corolla base. Ovary linear-cylindrical, apex attenuate. Styles 5, free, glabrous; stigmas depressed capitate. Capsules oblong-filiform.^[2] [more]

At least 426 species and subspecies belong to the Genus Acantholimon.

Allocasuarina

Allocasuarina is a genus in the flowering plant family Casuarinaceae. They are endemic to Australia, occurring primarily in the south. Like the closely related genus Casuarina, they are commonly called sheoaks or she-oaks, they are notable for their long, segmented branchlets that function as leaves. Formally termed cladodes, these branchlets somewhat resemble pine needles, although sheoaks are actually flowering plants. The leaves are reduced to minute scales encircling each joint. Fallen cladodes form a dense, soft mat beneath sheoaks, preventing the development of undergrowth and making sheoak woods remarkably quiet. [more]

At least 107 species and subspecies belong to the Genus Allocasuarina.

Beaufortia

Beaufortia is a genus of the botanical family Myrtaceae, endemic to Southwest Australia. Species include: [more]

At least 49 species and subspecies belong to the Genus Beaufortia.

Berzelia

At least 25 species and subspecies belong to the Genus Berzelia.

Boronia

Boronia is a genus of about 90-100 species of evergreen shrubs of the tribe Boronieae in the family Rutaceae. They are found all over Australia. [more]

At least 436 species and subspecies belong to the Genus Boronia.

More info about the Genus Boronia may be found here.

Campanula

Plants perennial or annual, erect trailing or decumbent, glabrous, pubescent, or hirsute. Leaves simple, alternate or forming rosettes at the base. Inflorescence 1-many flowered, with racemes or spikes. Flowers blue to purple or white. Sepals 5, with or without reflexed appendages between lobes; calyx tube adnate to the ovary, segments 5-lobed. Corolla campanulate, funnel-shaped or tubular. Stamens 5, free, filaments dilated at the base. Ovary 3-locular; style cylindrical; stigmas 3. Fruit a capsule, elongated to ovoid, obovoid or round, with membran¬ous walls; dehiscence by irregular pores at the bases or the sides. Seeds minute, numerous.^[3] [more]

At least 2,270 species and subspecies belong to the Genus Campanula.

Hemerocallis

Herbs, perennial, scapose, clump-forming, rhizomatous, from fibrous or fleshy contractile roots often enlarged at ends; rhizomes spreading. Leaves many, basal, sessile, 2-ranked, bases sheathing; blade long-linear, keeled, apex acuminate. Inflorescences 2, in terminal helicoid cyme, or solitary. Flowers mostly diurnal and ephemeral, slightly irregular, showy; tepals 6, connate basally into short, funnelform to campanulate tube, distinct parts imbricate, spreading, inner broader than outer; stamens 6, adnate to throat of perianth tube; filaments curved upward, distinct, unequal; anthers dorsifixed, 2-locular, linear-oblong, dehiscence introrse; ovary superior, green, 3-locular, conic, septal nectaries present; style curved upwards; stigma indistinctly 3-lobed or capitate. Fruits capsular, leathery, dehiscence loculicidal. Seeds rarely produced (sterile) or many. x = 11.^[4] [more]

At least 32,857 species and subspecies belong to the Genus Hemerocallis.

Ulmus

Trees, less often shrubs, to 35 m; crowns variable. Bark gray, brown, or olive to reddish, tan, or orange, deeply furrowed, sometimes with plates (smooth when young in Ulmus glabra ). Branches unarmed, slender to stout, some with corky wings; twigs glabrous to pubescent. Leaves sometimes tardily deciduous; stipules falling early. Leaf blade ovate to obovate or elliptic, base usually oblique, sometimes cordate or rounded to cuneate, margins serrate to doubly serrate; venation pinnate. Inflorescences fascicles, racemes, or cymes, pedunculate or subsessile, subtended by 2 bracts. Flowers on branches of previous season, appearing in spring before leaves or in fall, bisexual, pedicellate or sessile; calyx 3-9-lobed; stamens 3-9; styles persistent, deeply 2-lobed. Fruits samaras, usually flattened, membranously winged. x = 14.^[5] [more]

At least 441 species and subspecies belong to the Genus Ulmus.
