Coleonema is a genus of flowering plants in the family Rutaceae. The eight known species are all from the western Cape Province of South Africa. In Australia, where they are cultivated as garden ornamentals, they are often incorrectly referred to as Diosma. [more]
Cotoneaster () is a genus of woody plants in the rose family, Rosaceae, native to the Palaearctic region (temperate Asia, Europe, north Africa), with a strong concentration of diversity in the genus in the mountains of southwestern China and the Himalayas. They are related to hawthorns (Crataegus), firethorns (Pyracantha), photinias (Photinia) and rowans (Sorbus). [more]
Shrubs, subshrubs, or small trees, deciduous, rarely evergreen, armed, rarely unarmed; buds ovoid or subglobose. Leaves simple, stipulate, venation craspedodromous, margin serrate and lobed or partite, rarely entire. Inflorescences corymbose, sometimes flowers solitary. Hypanthium campanulate. Sepals 5. Petals 5, white, rarely pinkish. Stamens 5-25; carpels 1-5, connate, but free apically. Ovary inferior or semi-inferior, with 2 ovules per locule, but one rudimentary. Fruit a pome, with persistent sepals at apex; carpels bony when mature, each locule with 1 seed; seed erect, cotyledons plano-convex. [more]
Crataegus X Mespilus
Mahonia is a genus of about 70 species of evergreen shrubs in the family Berberidaceae, native to eastern Asia, the Himalaya, North America and Central America. They are closely related to the genus Berberis. Botanists disagree on the acceptability of the genus name Mahonia. Several authorities argue plants in this genus should be included in the genus Berberis because several species in both genera are able to hybridize, and because when the two genera are looked at as a whole, there is no definite morphological separation. Mahonia typically have large, pinnate leaves 10?50 cm long with 5-15 leaflets, and flowers in racemes (5?20 cm long). [more]
Medlar (Mespilus) is a genus of two species of in the subfamily Maloideae of the family Rosaceae. One, Common Medlar Mespilus germanica, is a long-known native of southwest Asia and possibly also southeastern Europe, and the other, Stern's Medlar Mespilus canescens, was recently (1990) discovered in North America. [more]
Shrubs deciduous or evergreen; buds small, with several narrow scales. Leaves imparipinnate; stipules linear to lanceolate; rachis narrowly winged; leaflets opposite, sessile or shortly petiolulate, small, margin entire. Corymb terminal, numerous flowered; bracts caducous. Hypanthium campanulate. Sepals 5. Petals 5, white. Stamens 20. Ovary inferior; 5-loculed, with 1 ovule per locule; styles 5, free. Fruit a small pome, with persistent erect sepals; seeds erect; cotyledons plano-convex. [more]
Firethorn (Pyracantha) is a genus of thorny evergreen large shrubs in the family Rosaceae, subfamily Maloideae. They are native from southeast Europe east to southeast Asia, and are closely related to Cotoneaster, but have serrated leaf margins and numerous thorns (Cotoneaster is thornless). [more]
The genus Tacca, which includes the Bat flowers and Arrowroot, consists of ten species of flowering plants in the order Dioscoreales, native to tropical regions of Africa, Australia, and south-eastern Asia. In older texts, the genus was treated in its own family Taccaceae, but the 2003 APG II system incorporates it into the family Dioscoreaceae. Taccaceae is native to Malaysia. [more]
At least 72 species and subspecies belong to the Genus Tacca.
