Tennantia is a monotypic genus of flowering plants belonging to the family Rubiaceae. [2] It only contains one known species, Tennantia sennii(Chiov.) Verdc. & Bridson [2] [1]
It is a shrub, 1–3 m (3 ft 3 in – 9 ft 10 in) tall, with whitish stems that are puberulous when young. The leaf-blades are elliptic to narrowly obovate in shape. They are 1–6.5 cm (0–3 in) long and 0.5–2.9 cm (0–1 in) wide. With rounded and sometimes minutely apiculate at the apex, glabrous or puberulous; stipules are 1–3 mm (0–0 in) long. Calyx with limb-tube about 1.2 mm (0 in) long, with lobes about 0.8 mm (0 in) long. The corolla is white or tinged pink; with the perianth tube 1.5–2 mm (0–0 in) long; the lobes are about 5 mm (0 in) long. The fruit (or seed capsule) is black, 5–6 mm (0–0 in) in diameter and glabrous. The seeds are about 4 mm (0 in) long. [3]
Its native range is from Somalia to Kenya and Tanzania in eastern Tropical Africa. [2]
The genus name of Tennantia is in honour of James Robert Tennant (b. 1928), a British botanist working at Kew Gardens. [4] The Latin specific epithet of sennii honors Lorenzo Senni (1879 - 1954), an Italian botanist who collected the type specimen. Both the genus and the species were first described and published in Kew Bull. Vol.36 on page 511 in 1981. [2] [1]
Kleinhovia is a monotypic genus of plants in the cotton, hibiscus and cacao family Malvaceae. The sole species in the genus is Kleinhovia hospita, commonly known as guest tree, an evergreen tree native to Indonesia, Malaysia and other parts of tropical Asia and the Pacific.
Alchornea ilicifolia, commonly known as the native holly, is a bush of eastern Australia. It grows in or on the edges of the drier rainforests in coastal parts of New South Wales and Queensland.
Roscoea alpina is a perennial herbaceous plant native to the Himalayas. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but R. alpina, like other species of Roscoea, grows in much colder mountainous regions. It is sometimes grown as an ornamental plant in gardens.
Roscoea australis is a perennial herbaceous plant found in Burma, to the south of all other members of the genus. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but R. australis, like other species of Roscoea, grows in much colder mountainous regions.
Lecythis zabucajo, the sapucaia or paradise nut, is a large nut-producing tree occurring in the Guianas, Suriname, Venezuela, Ecuador, Honduras and Brazil, and which distribution range is much the same as that of the greater spear-nosed bat. Although not singling out Lecythis zabucajo, Jacques Huber noted in 1909 that fruit bats played the most important role in seed dispersal in Amazonian forests. The quality of its nuts led to the species' being introduced to numerous tropical countries, notably Trinidad, where it has flourished. The nuts are a valuable food resource and yield oil suitable for cooking and domestic use.
Dillenia alata, commonly known as red beech, golden guinea flower or golden guinea tree, is a tree in the Dilleniaceae family, found in New Guinea, and the Northern Territory and Queensland in Australia. It has found some popularity as an ornamental for tropical parks and large gardens due to its colourful flowers and fruit.
Van-royena is a monotypic genus in the plant family Sapotaceae. The sole species is Van-royena castanosperma, commonly known as milky plum, yellow plum, saffron boxwood or poison plum, which is endemic to Queensland, Australia. It is an understorey tree of rainforest, first described in 1919.
Acacia burkittii is a species of wattle endemic to Western Australia, South Australia and western New South Wales, where it is found in arid zones, and is a perennial shrub in the family Fabaceae. Common names for it include Burkitt's wattle, fine leaf jam, gunderbluey, pin bush and sandhill wattle. It has also been introduced into India. Previously this species was referred to as Acacia acuminata subsp. burkittii, but is now considered to be a separate species. It grows in mallee, eucalypt and mulga woodland or shrubland, often on sandhills.
Hymenodictyon parvifolium Oliv. is a small rubiaceous African tree and is one of some 24 species in the genus, with a tropical African and Asian distribution. This species grows as a small tree to some 5 metres tall, or sometimes a liane or scrambler to 10.5 m, and is found in low-altitude woodland.
Pachystoma nutans, is a species of plant in the orchid family. It is endemic to Myanmar. It was first described by Sing Chi Chen and Yi Bo Luo in 2002. The type specimen of Pachystoma nutans was previously overlooked among unidentified Eulophia species at the Royal Botanic Garden herbarium in Edinburgh. It is only known from the type specimen, which was collected near Mong Yaw, Myanmar.
Gardenia actinocarpa is a rare and endangered plant in the coffee and gardenia family Rubiaceae, native to a very restricted area within the Wet Tropics rainforest of northeastern Queensland.
Henoonia is a monotypic genus of flowering plants belonging to the family Solanaceae. The only species is Henoonia myrtifolia. It is native to Cuba. It is a stiff bush, with a whitish bark, red-pubescent branches, alternate papery leaves of 3.0-3.8 cm long and 1.0-1.3 cm wide that grow from thickened nodes, with a very short leafstalk, shortly spade-shaped to oblong, the tip sharp or pointed, margin entire, veined, glabrous above, initially with soft rufous felty hair below but becoming glabrous with age except near the main vein. The rufous, velvety calyx of 2.5 mm long consists of 5 sepals, finally splitting under the fruit. Corolla merged, with 5 petal lobes, glabrous, with 5 anthers opposite the petal lobes. Ovary superior, unilocular, stigma simple and nearly seated. The velvety, globe- to egg-shaped berry of about 1.3 cm long is topped with a curved beak of about 0.6 cm. The endosperm is absorbed as the seed ripens, the seed skin leathery, the 2 cotyledons are leaf-like, and the embryonic root is short.
