Plants named in 1866

Parsley, or garden parsley (Petroselinum crispum), is a species of flowering plant in the family Apiaceae that is native to the Balkans. It has been introduced and naturalized in Europe and elsewhere in the world with suitable climates, and is widely cultivated as a herb and a vegetable. It is believed to have been originally grown in Sardinia, and was cultivated in around the 3rd century BC. Linnaeus stated its wild habitat to be Sardinia, from where it was brought to England and apparently first cultivated in Britain in 1548, though literary evidence suggests parsley was used in England in

Freesia is a genus of herbaceous perennial flowering plants in the family Iridaceae, first described as a genus in 1866 by Christian Friedrich Ecklon (1886) and named after the German botanist and medical practitioner, Friedrich Freese (1795–1876). It is native to the eastern side of southern Africa, from Kenya south to South Africa, most species being found in Cape Provinces. Species of the former genus Anomatheca are now included in Freesia. The plants commonly known as "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of a number of Freesia species. Some other species

Matteuccia is a genus of ferns with one species: Matteuccia struthiopteris (common names ostrich fern, fiddlehead fern, or shuttlecock fern). The species epithet struthiopteris comes from Ancient Greek words στρουθίων (strouthíōn) "ostrich" and πτερίς (pterís) "fern".

Keteleeria is a genus of three species of coniferous trees in the family Pinaceae first described as a genus in 1866. The genus name Keteleeria honours J.B. Keteleer (1813–1903), a French nurseryman. The group is related to the genera Nothotsuga and Pseudolarix. It is distinguished from Nothotsuga by the much larger cones, and from Pseudolarix by the evergreen leaves and the cones not disintegrating readily at maturity. All three genera share the unusual feature of male cones produced in umbels of several together from a single bud, and also in their ability, very rare in the Pinaceae, of

Acanthophoenix is a genus of flowering plants in the palm family from the Mascarene Islands in the Indian Ocean, where they are commonly called palmiste rouge. A genus long in flux, three species are currently recognized, though unsustainable levels of harvesting for their edible palm hearts have brought them all to near extinction in their habitat. They are closely related to the Tectiphiala and Deckenia genera, differing in the shape of the staminate flower. The name combines the Greek words for "thorn" and "date palm".

Keteleeria fortunei (zh: 油杉, you shan) is a coniferous evergreen tree. Originated in China, K. fortunei is an ancient relict species and a second-class national key protected plant, "mainly distributed in south subtropical to the middle subtropical edge". It is found in the provinces of Fujian, Guangdong, Guangxi, Guizhou, Hunan, Jiangxi, Yunnan, and Zhejiang. The tree grows in hills, mountains, and broadleaf forests at elevations of 200–1400 m. The lifespan of K. fortunei can reach more than a thousand years, and the height of a thousand-year-old tree can reach more than 40 meters.

Ipomoea imperati, the beach morning-glory (a name it shares with Ipomoea pes-caprae), is a species of flowering plant in the family Convolvulaceae. Like Ipomoea pes-caprae, its seeds disperse by floating in seawater. It has been found on the sandy shores of every continent except Antarctica. Ipomoea imperati and I. pes-caprae can be easily can be distinguished in that I. imperati has white flowers and I. pes-caprae usually has purple flowers. The leaves of I. imperati are more linear or lanceolate while those of I. pes-caprae tend to be more circular or ovate. It is considered an invasive
