Genera

Camassia

Herbs, perennial, from bulbs. Bulbs solitary or clustered, tunicate, ovoid to globose; tunic black or brown. Leaves basal, appearing whorled; blade linear, keeled. Inflorescences appearing terminal, racemose, bracteate; bracts sterile or subtending flowers, narrowly lanceolate. Flowers actinomorphic or zygomorphic; tepals 6, persistent, ± equal in 2 whorls of 3, distinct, violet, blue, or white, each 3-9-veined, lanceolate, ± twisted in drying; stamens 6; filaments inserted on receptacles at base of tepals, slender; anthers versatile, dehiscence introrse; ovary 3-locular, septal nectaries present, ovules 6-36; style filiform; stigma 3-lobed; pedicel spreading to incurving-erect in fruit. Fruits capsular, ovoid to ellipsoid or subglobose, dehiscence loculicidal. Seeds 6-36, lustrous black, obpyriform to ovoid-ellipsoid, 2-4 mm. x = 15.[1] [more]

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.[2] [more]

Cardamine

Herbs annual, biennial, or rhizomatous or tuberous perennial. Trichomes absent or simple. Stems erect or prostrate, leafy or rarely leafless and plant scapose. Basal leaves petiolate, rosulate or not, simple and entire, toothed, or 1-3-pinnatisect, or palmately lobed, sometimes trifoliolate, pinnately, palmately, or bipinnately compound. Cauline leaves alternate, (rarely opposite or whorled), simple or compound as basal leaves, petiolate or sessile and base cuneate, attenuate, auriculate, or sagittate, margin entire, dentate, or variously lobed. Racemes ebracteate or rarely bracteate throughout or only basally, corymbose or in panicles, elongated in fruit. Fruiting pedicels slender or thickened, erect, divaricate, or reflexed. Sepals ovate or oblong, base of lateral pair saccate or not, margin often membranous. Petals white, pink, purple, or violet, never yellow, rarely absent; blade obovate, spatulate, oblong, or oblanceolate, apex obtuse or emarginate; claw absent or strongly differentiated from blade, longer or shorter than sepals. Stamens 6 and tetradynamous, rarely 4 and equal in length; anthers ovate, oblong, or linear, obtuse at apex. Nectar glands confluent and subtending bases of all stamens; median glands 2 or rarely 4 or absent; lateral glands annular or semiannular. Ovules 4-50 per ovary. Fruit dehiscent siliques, linear or rarely narrowly oblong or narrowly lanceolate, latiseptate, sessile; valves papery, not veined, glabrous (or very rarely hairy), smooth or torulose, dehiscing elastically acropetally, spirally or circinately coiled; replum strongly flattened; septum complete, membranous, translucent; style distinct or rarely obsolete; stigma capitate, entire. Seeds uniseriate, wingless, rarely margined or winged, oblong or ovate, flattened; seed coat smooth, minutely reticulate, colliculate, or rugose; mucilaginous or not when wetted; cotyledons accumbent or very rarely incumbent.[3] [more]

Cedrus

Trees evergreen, monoecious; branchlets strongly dimorphic: long branchlets growing several cm each year and bearing very slow-growing, lateral short branchlets; winter buds small, scales persistent. Leaves spirally arranged and radially spreading on long branchlets, shorter and very densely clustered on short branchlets, needlelike, triangular or ± quadrangular in cross section, stiff, stomatal lines present both adaxially and abaxially, most numerous abaxially, vascular bundles 2, almost fused, resin canals 2, small, marginal. Cones borne on apex of short branchlets, solitary, erect. Pollen cones with many spirally arranged microsporophylls; microsporangia 2; pollen not saccate. Seed cones erect, light purple at fertilization, maturing in 2nd(or 3rd) year; ovulate scales spirally arranged, sessile, with small bracts and 2 ovules adaxially. Seed scales closely arranged, large, woody, those at base and apex of cone sterile, deciduous at maturity. Bracts minute, falling together with seed scales at maturity from persistent, central axis. Seeds with large, membranous wing. Cotyledons usually 6-10. Germination epigeal. 2n = 24.[4] [more]

Filipendula

Herbs perennial, rhizomatous. Rhizome short, oblique, here and there thickened into tubers, clothed with fibers. Stipules large or small, subcordate to ovate-lanceolate; leaf blade pinnate; leaflets pinnately or palmately lobed. Inflorescence corymbose-cymose or paniculate-cymose; central branch shortened and flowering first. Flowers bisexual, rarely unisexual (when plants dioecious) . Sepals 5, reflexed after flowering. Petals 5, imbricate, white, pink, or red, base clawed. Stamens 20€“40. Carpels 5€“15, inserted on plane or slightly elevated receptacle, free; ovules 1 or 2; style terminal; stigma capitate. Fruit an achene, free, compressed, crowned by base of style. Seed pendulous, terete, with very little endosperm. x = 7, 8.[5] [more]

Fothergilla

Shrubs, usually multitrunked, from short stolons, often forming dense clumps, not aromatic or resinous; twigs, leaves, and flower buds stellate-pubescent. Bark light gray on mature branches, smooth. Dormant buds naked, densely stellate-pubescent; terminal bud short-stalked or sessile, with 2-4 subtending scales. Leaves short-petiolate. Leaf blade elliptic to obovate to oblong, ovate, to nearly orbiculate, unlobed, pinnately veined, base oblique, cuneate, truncate to rounded, margins transparent, crenate or serrate-dentate, occasionally undulate to entire, apex rounded to acute. Inflorescences terminal, elongate, many flowered, dense spikes, sessile or short-pedunculate. Flowers bisexual, fragrant, basal flowers functionally staminate, appearing before leaves; calyx lobes 5-7(-9), erect, minute, irregular, forming shallowly campanulate hypanthium with adnate androecium; sepals connate; petals absent; stamens 12-32, conspicuous, in centrifugal sequence on rim of hypanthium; filaments white, 4-17 mm, conspicuous, the longest somewhat club-shaped distally; anthers dehiscing by 2 flaps; staminodes absent; ovary adnate to hypanthium, ca. 1/3 its length; styles 2, becoming hornlike, with recurved tip. Capsules in groups of more than 3, stylar beaks prominent, appressed stellate-pubescent mixed with longer, straight hairs on calyx rim and distally, loculicidal. Seeds 2 per capsule, reddish brown, glossy, bony, not winged. x = 12.[6] [more]

Fraxinus

Trees or rarely shrubs, deciduous or rarely evergreen. Leaves odd-pinnate, opposite or rarely whorled at branch apices; petiole and petiolule often basally thickened. Inflorescences terminal or axillary toward end of branches, or lateral on branches of previous year, paniculate; bracts linear to lanceolate, caducous or absent. Flowers small, unisexual, bisexual, or polygamous. Calyx 4-toothed or irregularly lobed, sometimes absent. Corolla white to yellowish, 4-lobed, divided to base or absent. Stamens 2, inserted at base of corolla lobes; filaments short, exserted at anthesis. Ovules 2 in each locule, pendulous. Style short; stigma ± 2-cleft. Fruit a samara with apically elongated wing. Seeds usually 1, ovate-oblong; endosperm fleshy; radicle erect.[7] [more]

At least 443 species and subspecies belong to the Genus Fraxinus.
