Encephalartos kisambo is a species of cycad in the family Zamiaceae native to Kenya and Tanzania. It is known as the Voi cycad. The species grows on steep, forested hills and rocky slopes, including cloud forest habitat. It is threatened by habitat loss and over-collection for the horticultural trade.

Plowmanianthus Faden & C.R.Hardy is a genus of plants with 5 species and 2 subspecies in the family Commelinaceae (the spiderwort and dayflower family). The genus is distributed from Panama to Amazonian Peru and Brazil.

Geogenanthus poeppigii, commonly called the seersucker plant, is a flowering plant species in the family Commelinaceae (the dayflower & spiderwort family). As currently circumscribed, the genus Geogenanthus includes two other species, G. ciliatus and G. rhizanthus. This species is named after 19th century German naturalist Eduard Friedrich Poeppig. Geogenanthus undatus is an outdated synonym for G. poeppigii.

Commelina sphaerorrhizoma is a monocotyledonous, herbaceous plant in the dayflower family from south-central Africa. This blue-flowered herb has been recorded from western Zambia, central Angola, and the southern portion of the Democratic Republic of the Congo, although at the time of its description it was known only from 11 collections and may be more broadly distributed. It is found in a variety of habitats ranging from woodlands to grasslands to roadsides. The plant's most distinctive feature and the source of its scientific name is its moniliform rhizome composed of spherical segments

Commelina orchidophylla is a monocotyledonous, herbaceous plant in the dayflower family from south-central Africa. This blue-flowered herb has been recorded only from the Haut-Katanga District of the Democratic Republic of the Congo, although at the time of its description it was known only from 3 collections. It is found in woodlands, especially in rocky areas, and on sandstone. The plant's most distinctive feature and the source of its scientific name is its orchid-like pair of broad basal leaves. Other distinctive characteristics include hairy tuberous roots, solitary spathes on long

Commelina lukei is a monocotyledonous, herbaceous plant in the dayflower family from East Africa. This blue-flowered herb has been recorded in lowland areas of Kenya, Tanzania (including Zanzibar), and Madagascar, where it is found in a variety of habitats ranging from forests to grasslands to roadsides. Described in 2008, the species was previously confused with Commelina mascarenica and Commelina imberbis. Despite this misinterpretation, a third similar species, Commelina kotschyi, is actually most closely related to C. lukei. The plant's distinctive features include a scrambling habit,

Tricarpelema brevipedicellatum is a monocotyledonous herbaceous plant in the family Commelinaceae. The species is known from only two collections made in Vietnam and very little is known about it.

Tricarpelema africanum is a monocotyledonous flowering plant in the family Commelinaceae. It is native to west-central Africa and is typically found growing in shallow soils on inselbergs. The species is the only member of its genus not found in the moist forests of tropical Asia and the only species of the subgenus Keatingia. Tricarpelema africanum's physical separation from its Asian relatives has led it to evolve a number of unique morphological features, most of which are vegetative adaptations to drier conditions.

Palisota flagelliflora is a plant species endemic to Cameroon. It grows on the ground in secondary tropical forests. Palisota flagelliflora is the only known species in its genus that reproduces by means of stolons arising aerially within a rosette then running horizontally along the forest floor. Leaves are mostly in rosettes, the petioles up to 20 cm, the blades up to 40 cm. Inflorescences are created at nodes along the stolon, each inflorescence consisting of maroon bracts up to 4 cm long, subtending a small group of flowers, some staminate, others hermaphroditic. Sepals are boat-shaped,

Tricarpelema pumilum is a monocotyledonous herbaceous plant in the family Commelinaceae. It is known from only six collections on the island of Borneo. The species looks like a smaller version of the closely related Tricarpelema philippense, but the two can be differentiated based on the size and shape of the capsule, as well as the number of seeds per locule.

Tricarpelema philippense is a monocotyledonous herbaceous plant in the family Commelinaceae. It occurs in maritime Southeast Asia in the Philippines, Malaysia, and Indonesia.

Murdannia dimorphoides is a plant species endemic to Sri Lanka, known from only one location inside Wilpattu National Park. Murdannia dimorphoides is an annual, trailing herb sometimes rooting at the nodes. Leaves are narrow, up to 12 cm long. Some flowers are hermaphroditic, others staminate only, either way lilac to lavender, up to 15 mm across.

Dichorisandrinae is a subtribe within the tribe Tradescantieae of the flowering plant family Commelinaceae. It consists of 5 genera and around 51 species. The subtribe represents a diverse assemblage native to tropical South America and a contiguous portion of Central America. Not only is this subtribe remarkable for the range of morphological and ecological variation within it, but it also includes species that represent novel exceptions to the terrestrial habit, longitudinally-dehiscent anthers, and/or exarillate seeds typical of the family. Exceptional taxa include Dichorisandra,

Commelina polhillii is a plant species native to Tanzania, known only from the Iriniga and Mpanda Districts. It occurs in open woodlands and in disturbed sites. Commelina polhillii is an annual herb with ascendent(=reclining for a while then turning upward) to decumbent (=trailing) stems up to 75 cm long. Stems are flattened on one side, sometimes maroon or with maroon stripes. Leaves are narrowly lanceolate, tapering at the tip, up to 12 cm long, sometimes with cilia (=long soft hairs) along the margins. Spathes are solitary, each with 3 or 4 flowers. Sepals are translucent. Petals are
