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]

Rhipogonaceae (sometimes Ripogonaceae) is the of a family of flowering plants. The family is confined to eastern Australia, New Zealand, and New Guinea. Rhipogonaceae is composed entirely of woody vines in the genus Rhipogonum (sometimes Ripogonum). Until recently this family was included in Smilacaceae, and its separation has been a matter of some debate. However, both the APG system and APG II system do recognize such a family and place it in the order Liliales, and the clade monocots. It differs from the closely related Smilacaceae only in that Rhipogonaceae is a twining vine that lacks tendrils, its seeds contain starch, the flowers are hermaphroditic, and the five sided anthers are longer than the filaments.

Streptocarpus is a of herbaceous flowering plants in the family Gesneriaceae, closely related to the genus Saintpaulia. One common name is Cape Primrose, referring to the nativity of several species to South Africa and their superficial resemblance to the genus Primula. The genus is native to parts of Africa and Madagascar (with a few odd species in Asia that probably do not belong in the genus). The plants often grow on shaded rocky hillsides or cliffs. About 155 species of Streptocarpus are currently recognized, the first described being S. rexii. They are found growing on the ground, rock crevices, and almost anywhere the seed can germinate and grow. Some species such as S. dunnii are unifoliate with the plant producing no true leaves, only a single cotyledon that continues to grow throughout the life of the plant. The unifoliate species are monocarpic and die after producing seeds. Other species are perennial and come into flower during different parts of the year. Members of subgenus Streptocarpella are more typical caulescent herbs and are sometimes grown as bedding or hanging plants. The genus is defined by having a spirally twisted fruit (hence the name "streptocarpus"), although this character is also found in some other Old World genera of Gesneriaceae. Recent phylogenetic studies strongly suggest that although it does not have a twisted fruit the genus Saintpaulia has evolved from within subgenus Streptocarpella. [more]
