Tofieldiaceae is a family of flowering plants in the monocot order Alismatales. The family is divided into four genera, which together comprise 28 known species. They are small, herbaceous plants, mostly of arctic and subarctic regions, but a few extend further south, and one genus is endemic to northern South America and Florida. Tofieldia pusilla is sometimes grown as an ornamental.
Cuphocarpus is an obsolete genus of flowering plants in the family Araliaceae. Mabberley (2008) treated it as a synonym of Polyscias, but other authors still recognized it at that time. In 2010, in a phylogenetic analysis of DNA sequences, it was shown that Cuphocarpus was biphyletic and embedded in the large genus Polyscias. In an accompanying paper, Polyscias was divided into 11 subgenera, with seven species left incertae sedis.
Reynoldsia is an obsolete genus of flowering plants in the ivy family, Araliaceae. In 2003, Kew Gardens published a checklist for Araliaceae, in which eight species were recognized for Reynoldsia: four from Samoa, two from Tahiti, one from the Marquesas, and one from Hawaii. In 2010, a phylogenetic comparison of DNA data showed that Reynoldsia was polyphyletic, consisting of two groups that are not each other's closest relatives. In a companion paper, three of the species were "sunk" into synonymy with others, reducing the number of species to five. All species that were formerly in Reynoldsia are now in ''Polyscias'' subgenus Tetraplasandra, a subgenus of 21 species indigenous to Malesia and Pacific islands.
Graderia is a genus of plants in the family Orobanchaceae, which is native to Africa and Socotra. It belongs to the tribe Buchnereae. It is a hemiparasitic taxon.

Hymenodictyon is a genus of flowering plants in the family Rubiaceae. It has about 30 species. All are native to the Old World. The wood of Hymenodictyon orixense is soft and has limited use, mostly for boxes. The type species for Hymenodictyon is Hymenodictyon orixense.
Hillia is a genus of flowering plants in the family Rubiaceae. It has 24 species. All are indigenous to tropical America.
Grubbia is a genus of flowering plants in the family Grubbiaceae. The genus has three species, all endemic to the Cape Floristic Region of South Africa. They are shrubs that grow to 1.5 m (4.9 ft) tall, with tiny flowers and slender, leathery leaves. The fruit is a syncarp.
Capelio is a genus of flowering plant in the Asteraceae first described as a genus in 1836 with the name Alciope. It was renamed Capelio in 2002 after it was determined that the name Alciope was not legitimately published according to international nomenclatural rules. Capelio is a taxonomic anagram derived from the former name Alciope.
Leptorhabdos is a monotypic genus of flowering plants, initially classified in Scrophulariaceae, and now within the broomrape family Orobanchaceae. It contains a single species, Leptorhabdos parviflora.
Crossopetalum, commonly known as Christmas-berries or maiden berries, is a genus of flowering plants in the family Celastraceae. It comprises about 30-40 species.
Kailarsenia is a genus of flowering plants in the tribe Gardenieae of the family Rubiaceae. Its native range is Indo-China to West Malesia.
Larsenaikia is a genus of flowering plants in the tribe Gardenieae of the family Rubiaceae. Its native range is Eastern and Northern Australia.
Manekia is a genus of flowering plants in the family Piperaceae.
