Genera
Galanthus
Herbs, perennial, scapose, from brown, tunicate, ovoid to globose bulbs; offset bulbs often present. Leaves 2(-3), basal, opposite, with sheathing blade, vernation flat and parallel, or convolute; nonsheathing blade erect to recurving at maturity, grayish green, linear-oblanceolate, glaucous; sheathing blade white, tubular, membranous, enclosing leaf bases and scape. Scape erect in flower, prostrate in fruit, green, solid. Inflorescences pendulous, 1-flowered, spathaceous; spathe bracteate, membranous; bracts 2, connate, split on 1 side. Flowers nodding, fragrant; perianath 2.5 cm or shorter; tepals 6, distinct, unequal; outer tepals spreading, white, narrowly obovate to almost orbicular, larger than inner; inner tepals overlapping, appearing tubular, green-spotted at apex only or apex and base, straight to semiorbicular, apex notched; stamens 6, inserted at bases of tepals, distinct; anthers basifixed, longer than filaments, bases lobed, apices tapered, dehiscense introrse, via terminal slits; ovary inferior, green, 3-locular, globose, septal nectaries present; style, white, unbranched, filiform; stigma indistinct to minutely capitate; pedicel wiry, short, slender. Fruits capsular, green, globose, fleshy, dehiscence loculicidal. Seeds 18-36, light brown, 3.5 mm, oblong to obtuse, elaiosomes fleshy. x = 12.[1] [more]
Lapiedra
Leucojum
Herbs, perennial, scapose, from brown, globose to ovoid, tunicate bulb. Leaves several; blade linear-ligulate, base sheathing. Scape stout, hollow [slender, solid]. Inflorescences umbellate, 2-5(-7) -flowered, spathaceous; spathe bracts 2, free or entirely adnate on 1 side, appearing monophyllous. Flowers nodding; perianth campanulate; tepals 6, distinct, oblanceolate to ovate, equal; stamens 6, distinct; anthers basifixed, conic, longer than filaments, blunt apically, dehiscing by terminal pores; ovary inferior, green, 3-locular, globose, septal nectaries present; style filiform or clavate, exceeding anthers; stigma minutely capitate. Fruits capsular, erect, pyriform to subglobose, dehiscence loculicidal; pericarp somewhat fleshy. Seeds numerous, black, appendages absent. x = 7, 8, 9, 10, 11, 12.[2] [more]
Leucopogon
Leucopogon is a genus of about 150-160 species of flowering plants belonging to the family Ericaceae, in the section of that family formerly treated as the separate family Epacridaceae. They are native to Australia, New Zealand, New Caledonia, the western Pacific Islands and Malaysia, with the greatest species diversity in southeastern Australia. The common name is beard-heath or beard heath. [more]
At least 371 species and subspecies belong to the Genus Leucopogon.
