Taxonomy

The Tribe Epilobieae is further organized into finer groupings including:

• Genus (5): Chamaenerion · Chamerion · Epilobium · Meconopsis · Zauschneria
• Species: ZipcodeZoo has pages for 475 species, subspecies, varieties, forms, and cultivars in the Tribe Epilobieae.

Genera

Chamaenerion

Epilobium is a in the family Onagraceae, containing about 160-200 species of flowering plants with a world-wide distribution. They are generally abundant in the subarctic, temperate and subantarctic regions, whereas in the subtropics and tropics they are trestricted to the cool montane biomes, such as the New Guinea Highlands where they are plentiful.

Chamerion

Herbs perennial, erect, usually clumped, with shoots from woody caudex or spreading lateral roots. Stems simple or rarely branched, pubescent to subglabrous, hairs always eglandular. Leaves spirally arranged, rarely subopposite or subverticillate, subleathery, basal ones sessile, upper ones usually petiolate; stipules absent; bracteoles absent. Inflorescence a simple raceme or spike, rarely branched. Flowers 4-merous, slightly zygomorphic, strongly protandrous, lacking a floral tube, producing nectar from raised disk at base of style and stamens. Petals pink to rose-purple, rarely white, obcordate or obtrullate, entire. Stamens 8, subequal in single whorl, erect at onset of anthesis, later reflexed; pollen blue or yellow, shed in monads. Style initially deflexed, becoming erect as stigma deflexes; stigma deeply 4-lobed and revolute, receptive on inner surfaces. Fruit an elongate capsule, slender, 4-loculed, loculidical. Seeds many, with terminal coma of silky hairs. 2n = 36, 72, 108.^[1] [more]

Epilobium

Herbs perennial [or annual, sometimes suffrutescent], with leafy rosettes, stolons, soboles (shoots), or turions (subterranean globose buds with fleshy scales) . Stems glabrous to pubescent, often with lines of hairs decurrent from margins of petioles. Leaves opposite, becoming alternate and bractlike in inflorescence; petiolate or sessile; stipules absent; bracteoles absent. Inflorescences simple or branched racemes, panicles, spikes, or corymbs. Flowers 4-merous, often protandrous, with floral tube, producing nectar at base of style. Petals pink to rose-purple or white [or rarely cream-colored or orange-red], obcordate or obtrullate, notched at apex. Stamens 8, in two unequal whorls; pollen yellow, shed in tetrads. Style erect; stigma entire or 4-lobed. Fruit an elongate, slender capsule, 4-loculed, loculidical. Seeds many [or rarely only 4], generally with terminal coma of silky hairs [or coma rarely lacking]. 2n = [18, 20, 24, 26, 28, 30, 32,] 36, [38, 60].^[2] [more]

Meconopsis

Perennial, often prickly, simple or rarely branched, often tall and robust herbs with yellow latex. Leaves entire or lobed, radical stalked, cauline sessile or subsessile. Inflorescence solitary, racemed, pseudo-racemed or panicled. Flowers often large, showy, blue, yellow or purplish-red. Sepals 2(-4), usually caducous, valvate. Petals 4 (often varying from 5-10), free, obovate to broadly ovate. Stamens many, multiseriate; filament filiform; anthers often oblong. Carpels many, fused, superior, with unilocular, ellipsoid to subglobose ovary; ovules many on parietal placentae projecting into the ovary; style distinct, often short; stigma rays 5-6, radiating and forming a globular mass over the ovary. Capsule ovoid, oblong, clavate or cylindrical, 1-celled, dehiscing by short slits at the apex or sometimes splitting almost to the base of the fruit. Seeds many, small, rugose.^[3] [more]

Zauschneria

Zauschneria (Epilobium canum) is a of willowherb, native to dry slopes and in chaparral of western North America. It is a perennial plant, notable for the profusion of bright scarlet flowers in late summer and autumn. [more]

At least 59 species and subspecies belong to the Genus Zauschneria.
