Araucaria heterophylla (synonym A. excelsa) is a species of conifer. As its vernacular name Norfolk Island pine (or Norfolk pine) implies, the tree is endemic to Norfolk Island, an external territory of Australia located in the Pacific Ocean between New Zealand and New Caledonia. It is not a true pine, which belong to the genus Pinus in the family Pinaceae, but instead is a member of the genus Araucaria in the family Araucariaceae, which also contains the hoop pine and the monkey-puzzle tree. Members of Araucaria occur across the South Pacific, especially concentrated in New Caledonia (about

The Dioncophyllaceae are a family of flowering plants consisting of three species of lianas native to the rainforests of western Africa. Their closest relatives are Ancistrocladaceae. Both families lie within a clade of mostly carnivorous plants which, since 1998 or so, have been moved to the order Caryophyllales. This clade also includes the families Droseraceae (sundews and Venus' flytrap) and Nepenthaceae (an Old World genus of pitcher plants), as well as Drosophyllaceae. All species in the family are lianas at some point in their lifecycles, and climb by the use of pairs of hooks or

Aloe nyeriensis is a succulent aloe plant species, endemic to Kenya. It grows from 1–3 metres tall, and sends up an inflorescence on a flowering stalk from 0.5 to 0.8 metres tall, densely packed with red flowers. A. nyeriensis grows on rocky soils of the savannah, often in communities with Acacia trees, at altitudes between 1760 and 2100 metres. It is closely related to - and often confused with - its relative Aloe kedongensis. It is listed as Vulnerable on the IUCN Red List of threatened species.

Pueraria mirifica, also known as กวาวเครือ kwao krua (among other names), is a plant found in northern and northeastern Thailand and Myanmar. In Thailand, the plant is known as "kwao krua kao", the 'kao' meaning white which distinguishes Pueraria mirifica from other plants with tuberous roots also sharing the 'kwao krua' designation, such as Butea superba, commonly called kwao krua deng (red) and the 'black' and 'dull grey' kwao krua plants. The species was definitively identified as Pueraria mirifica in 1952. Dried and powdered, the tuberous root of Pueraria mirifica has a history of

Flowers are small, to 5 mm in diameter, and occur in terminal panicles. The flowers have four to five unequal petals,

Gilbertiodendron dewevrei is a species of tree in the family Fabaceae, native to tropical rain forests in Central Africa. It is often the dominant tree species of the Guineo-Congolian rainforest. The timber is traded as limbali, and is used for construction, flooring and railway sleepers. It is also used for making boats, furniture, tool handles and joinery and for making charcoal.

Virectaria is a genus of flowering plants in the family Rubiaceae. The genus, known as Virecta until 1952, consists exclusively of tropical African species. It is a Guineo-Congolian genus, having its highest diversity in Lower Guinea but it also occurs in the Zambezian Region. Verdcourt provided a revision in which he defined five species but three more were added later. In 2001, a detailed morphological and anatomical study of the genus was conducted and a taxonomic survey and a key to the species was provided.

Samaipaticereus corroanus is a species of cactus in the subtribe Trichocereinae, native to Bolivia and Peru. Along with Cleistocactus inquisivensis, Cleistocactus corroanus has been placed in the genus Samaipaticereus. A 2023 molecular phylogenetic study led to Cleistocactus being expanded to include Samaipaticereus, among other genera. The expansion is accepted by Plants of the World Online as of March 2025.

Medusandra is a genus of flowering plants in the family Peridiscaceae. It has two species, Medusandra richardsiana and Medusandra mpomiana. M. richardsiana is the most common and well known. Both species are native to Cameroon and adjacent countries. Medusandra was named by John Brenan in 1952. Brenan put Medusandra in its own family, Medusandraceae, and added Soyauxia to that family in 1953. Most authors, however, maintained Medusandraceae as a monogeneric family and put Soyauxia elsewhere. A detailed description of Medusandra was published by John Hutchinson in 1973. When the APG II system

Lilium rhodopeum is a European species of plants in the lily family. It is endemic to the Rhodopi Mountains of Bulgaria and Greece, where it is found in alpine meadows and on mountain slopes. It is as critically endangered and listed as an IUCN (International Union for Conservation of Nature) red list threatened species. This Balkan endemic can be found in Bulgaria and Greece where it is native to the Rhodopi mountains from which it takes it name.

Amentotaxus formosana, the Taiwan catkin yew, is a species of conifer in the family Taxaceae. It is a small tree to 10 m (33 ft) tall, with a slender trunk. It was previously recognised as a variant of Amentotaxus argotaenia. Amentotaxus formosana is found only in Taiwan where it only occurs in four localities of cloud forest in the Hengchun Peninsula, in the extreme south of the island. IUCN considers A. formosana as critically endangered because of its populations are small and threatened by habitat loss. The populations are characterized by very low levels of genetic diversity. The wood is
