Phragmipedium kovachii is an orchid species found to be new to science in 2001, native to the Andean cloud forests of northern Peru. A species with terrestrial habit and growing in clumps of several individuals, it displays showy pink to purple flowers up to 20 cm (8 in) wide. It is currently considered a critically endangered species by the IUCN, due to overcollection in the wild.
Boswellia is a genus of trees in the order Sapindales, known for its fragrant resin. The biblical incense frankincense is an extract from the resin of the tree Boswellia sacra, and is now produced also from B. frereana.
Quercus lyrata, the overcup oak, is an oak in the white oak group. The common name, overcup oak, refers to its acorns that are mostly enclosed within the acorn cup. It is native to lowland wetlands in the eastern and south-central United States, in all the coastal states from New Jersey to Texas, inland as far as Oklahoma, Missouri, and Illinois. There are historical reports of it growing in Iowa, but the species appears to have been extirpated there. It is a slow-growing tree that often takes 25 to 30 years to mature. It has an estimated lifespan of 400 years.
Ulmus gausseniiW. C. Cheng, the Anhui, or hairy, elm, is a medium size deciduous tree whose natural range is restricted to the valleys of the Langya limestone mountains of Chu Xian in Anhui Province, eastern China. The tree was most commonly found on the flood plains, indicating a tolerance of periodic inundation. However, U. gaussenii is now possibly the rarest and most endangered elm species, with only approximately 30 trees known to survive in the wild in 2009. The tree was introduced to the West in 1995, at the Morton Arboretum, Illinois, as part of an evaluation of Chinese elms for landscape use.
Adansonia suarezensis, the Suarez baobab, is an endangered species of Adansonia endemic to Madagascar. It is locally called "bozy", the common name used for all baobabs in northern Madagascar.

Boswellia ameero is a species of flowering plant in the Burseraceae family. It is endemic to the island of Socotra in Yemen, common locally in arid, partly deciduous forests; however, populations are fragmentary, with aged, seldom regenerating trees being dominant.

Boswellia socotrana is a species of plant in the Burseraceae family. It is endemic to Socotra, Yemen. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland.
Barringtonia asiatica is a species of Barringtonia native to mangrove habitats from islands of the Indian Ocean in the west to tropical Asia and islands of the western Pacific Ocean. It is grown along streets for decorative and shade purposes in some parts of India, for instance in some towns on the southeastern shore. It is also known as Box Fruit due to the distinct box-shaped fruit it produces. The local name futu is the source of the name for the Polynesian island Futuna. The type specimen was collected by botanist Pehr Osbeck on a sandy beach area on the island of Java, later to be described by Carl Linnaeus in his Species Plantarum in 1753.

The species is endemic to the island of Socotra in Yemen, and is the only species in the Cucurbitaceae to grow in a tree form. The species name was originally spelled D. socotrana, but this is corrected to masculine grammatical gender according to the International Code of Nomenclature for algae, fungi, and plants.
Tabernaemontana pandacaqui, known as windmill bush and banana bush, is a species of plant in the dogbane family Apocynaceae.

Betula chichibuensis, commonly known as Chichibu birch, is a species of birch native exclusively to limestone outcrops in the Okuchichibu and Kitakami Mountains of central and northeast Honshu, Japan. The tree is rated as Critically Endangered on the IUCN Red List due to its extreme rarity and limited range.
