Buxus is a genus of about 70 species in the family Buxaceae. Common names include box (majority of English-speaking countries) or boxwood (North America). [more]
Castanopsis (chinquapin or chinkapin) is a genus of evergreen trees belonging to the beech family, Fagaceae. The genus contains about 120 species, which are today restricted to tropical and subtropical eastern Asia. A total of 58 species are native to China, with 30 endemic; the other species occur further south, through Indochina to Indonesia, and also in Japan. The English name chinkapin is shared with other related plants, including the golden chinkapins of the Pacific United States, which are sometimes included within Castanopsis but are more often considered a separate but very closely related genus, Chrysolepis. [more]
Chrysolepis is a small genus in the beech family Fagaceae, endemic to the western United States, occurring from western Washington south to southern California. They are evergreen trees and shrubs with simple, entire (untoothed) leaves with a dense layer of golden scales on the underside (hence the genus name, from Greek chryso-, yellow, and lepis, scale) and a thinner layer on the upper side; the leaves persist for 3-4 years before falling. The fruit is a densely spiny cupule containing usually three sweet, edible nuts. [more]
Lithocarpus is a genus in the beech family Fagaceae, differing from Quercus in the erect male spikes. The Kew Checklist (see link below) accepts 334 species, though some other texts suggest as low as 100 species. All but one are native to east and southeast Asia; the single exception, Lithocarpus densiflorus (Tanoak), being native to western North America in southwest Oregon and California. The Asian species do not have a well-known English vernacular name, though the generic term stone oak has been proposed. [more]
Trees, deciduous. Winter buds ovate, enclosed by scales. Leaves alternate; stipules absent; leaf blade margin serrate. Pedicel elongated, jointed. Flowers bisexual, 1 or 2 in leaf axils of older shoots, opening before or at same time as leaves. Calyx tube obconical, adnate to ovary, 4-toothed to undulate, expanding in fruit. Corolla campanulate, divided almost to base; lobes 5, imbricate. Stamens 10, in 1 series, equal, much shorter than corolla; filaments basally connate into a tube, adnate to corolla tube; anthers oblong. Ovary inferior, imperfectly 5-locular; ovules 4 per locule, erect to pendulous, placentation axile. Style slender, linear; stigma capitate or obscurely 5-lobed. Fruit mostly adnate to calyx, ribbed or angular, tomentose apex usually produced beyond the calyx into a beak, wall thick and woody, indehiscent. Seeds ellipsoid, flattened; seed coat membranous; endosperm fleshy. [more]
Osmanthus (Osmanthus) is a genus of about 30 species of flowering plants in the family Oleaceae, mostly native to warm temperate Asia (from the Caucasus east to Japan) but one species (O. americanus) in North America (southeastern United States, Texas to Virginia). They range in size from shrubs to small trees, 2-12 m tall. The leaves are opposite, evergreen, and simple, with an entire, serrated or coarsely toothed margin. The flowers are produced in spring, summer or autumn, each flower being about 1 cm long, white, with a four-lobed tubular-based corolla ('petals'). The flowers grow in small panicles, and in several species have a strong fragrance. The fruit is a small (10-15 mm), hard-skinned dark blue to purple drupe containing a single seed. [more]
An oak is a tree or shrub in the genus Quercus (; Latin "oak tree"), of which about 600 species exist. "Oak" may also appear in the names of species in related genera, notably Lithocarpus. The genus is native to the northern hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in Asia and the Americas. [more]
Trigonobalanus is a genus of three species of evergreen in the family Fagaceae, related to beeches and chestnuts. The species are widely scattered, with one in northern South America and two in southeast Asia; some botanists treat the three species in separate genera. The three species, with their authors, major synonyms and distribution, are: [more]
At least 3 species and subspecies belong to the Genus Weldenia.
