Plants named in 1806

The Passifloraceae are a family of flowering plants, containing about 750 species classified in around 27 genera. They include trees, shrubs, lianas, and climbing plants, and are mostly found in tropical regions. The family takes its name from the passion flower genus (Passiflora) which includes the edible passion fruit (Passiflora edulis), as well as garden plants such as maypop and running pop. Passiflora vines and Dryas iulia (among other heliconian butterflies) have demonstrated evidence of coevolution, in which the plants attempted to stop their destruction from larval feeding by the

Sesbania grandiflora, common names vegetable hummingbird, katurai, agati, agastya, agasya, kathurumurunga and West Indian pea, is a leguminous tree of family Fabaceae native to Malesia, including Malaysia, New Guinea, and the Philippines. It is widely distributed globally in equatorial regions. The flowers are eaten in Southeast and South Asia.

Gagea is a large genus of spring flowers in the lily family. Gagea are perennially flowering plants. It is found primarily in Eurasia with a few species extending into North Africa and one species (Gagea serotina) in North America. The genus is named after the English naturalist Sir Thomas Gage (1781–1820). They were originally described as species of Ornithogalum, which, together with the usual yellow colour of the flowers, explains the English name yellow star-of-Bethlehem for the common European species, Gagea lutea.

The Rhizophoraceae is a family of tropical or subtropical flowering plants. It includes around 147 species distributed in 15 genera. Under the family, there are three tribes, Rhizophoreae, Gynotrocheae, and Macarisieae. Even though Rhizophoraceae is known for its mangrove members, only the genera under Rhizophoreae grow in the mangrove habitats and the remaining members live in inland forests.

The ackee (Blighia sapida), also known as acki, akee, or ackee apple, is a fruit of the Sapindaceae (soapberry) family, as are the lychee and the longan. It is native to tropical West Africa. The scientific name honours Captain William Bligh who took the fruit from Jamaica to the Royal Botanic Gardens in Kew, England, in 1793. The English common name is derived from the West African Akan-language name akye fufo. Although having a long-held reputation as being poisonous with potential fatalities, the fruit arils are renowned as delicious when ripe, prepared properly, and cooked and are a

Raffia palms are members of the genus Raphia. The Malagasy name rafia is derived from fia "to squeeze juice". The genus contains about twenty species of palms native to tropical regions of Africa, and especially Madagascar, with one species (R. taedigera) also occurring in Central and South America. R. taedigera is the source of raffia fibers, which are the veins of the leaves, and this species produces a fruit called "brazilia pods", "uxi nuts" or "uxi pods". They grow up to 16 metres (52 ft) tall and are remarkable for their compound pinnate leaves, the longest in the plant kingdom; leaves

Senegalia catechu, previously known as Acacia catechu, is a deciduous, thorny tree which grows up to 15 m (50 ft) in height. The plant is called kachu in Malay; the Malay name was Latinized to "catechu" in Linnaean taxonomy, as the species from which the extracts cutch and catechu are derived. Other common names for it include kher, catechu, cachou, cutchtree, black cutch, and black catechu. Senegalia catechu is native to South Asia and Southeast Asia, including the Indian subcontinent, Myanmar, Cambodia and China (Yunnan). Through derivatives of the flavanols in its extracts, the species has
