Plants named in 1828

Pinus canariensis, the Canary Island pine, is a species of gymnosperm in the conifer family Pinaceae. It is a large, evergreen tree, native and endemic to the outer Canary Islands of the Atlantic Ocean.

The Bryopsida constitute the largest class of mosses, containing 95% of all moss species. It consists of approximately 11,500 species, common throughout the whole world. The group is distinguished by having spore capsules with teeth that are arthrodontous; the teeth are separate from each other and jointed at the base where they attach to the opening of the capsule. Consequently, mosses in the Class Bryopsida are commonly known as the "joint-toothed" or "arthrodontous" mosses. These teeth are exposed when the covering operculum falls off. In other groups of mosses, the capsule is either

Echeveria is a large genus of flowering plants in the family Crassulaceae, native to semi-desert areas of Central America, Mexico and northwestern South America.

Clivia is a genus of monocot flowering plants native to southern Africa. They are from the family Amaryllidaceae, subfamily Amaryllidoideae. Common names are Natal lily or bush lily. They are herbaceous or evergreen perennial plants, with green, strap-like leaves. Individual flowers are more or less bell-shaped, occurring in umbels on a stalk above the foliage; colors typically range from yellow through orange to red. Many cultivars exist, some with variegated leaf patterns.

Nicotiana glauca is a species of flowering plant in the tobacco genus Nicotiana of the nightshade family Solanaceae. It is known by the common name tree tobacco. Its leaves are attached to the stalk by petioles (many other Nicotiana species have sessile leaves), and its leaves and stems are neither pubescent nor sticky like Nicotiana tabacum. It resembles Cestrum parqui but differs in the form of leaves and fusion of the outer floral parts. It grows to heights of more than two meters. Tree tobacco is native to South America but it is now widespread as an introduced species on other

Alnus cordata, the Italian alder, is a tree or shrub species belonging to the family Betulaceae, and native to the southern Apennine Mountains (Campania, Basilicata and Calabria, mainly on western mountain sides) and the north-eastern mountains of Corsica. It has been introduced in Sicily, Sardinia, and more recently in Central-Northern Italy, other European countries (France, Belgium, Spain, Portugal, United Kingdom) and extra-European countries (Chile, New Zealand), where it has become naturalised.

The Penaeaceae are a family of evergreen, leathery-leaved shrubs and small trees, native to South Africa. The family has 29 species in 9 genera. The family Penaeaceae was expanded under the APG III system of classification with the inclusion of the genera Olinia (formerly in the monogeneric Oliniaceae) and the single species from the genus Rhynchocalyx (formerly in the monogeneric Rhynchocalycaceae).

Columelliaceae is a family of trees and shrubs native to the Andes of South America. In the APG II taxonomy it is placed in the order Lamiales, but a 2008 study suggested that the family is sister to the Bruniaceae, and the Angiosperm Phylogeny Website proposes incorporating this finding by placing both families in order Bruniales. The APG III system of 2009 thus does place Columelliaceae in the Bruniales.

Bryaceae is a family of mosses.

Epipactis purpurata, the violet helleborine, is an orchid widely distributed in Europe.

Caryocar brasiliense, known as pequi (Portuguese pronunciation: [peˈki]) or souari nut, is an edible fruit popular in some areas of Brazil, especially in central-west Brazil.

Streptocarpus ("twisted fruit" from Greek στρεπτός (streptos) "twisted" and καρπός (karpos) "fruit") is an Afrotropical genus of flowering plants in the family Gesneriaceae. The genus is native to Afromontane biotopes from central, eastern and southern Africa, including Madagascar and the Comoro Islands. The flowers are five-petalled, salverform tubes, almost orchid-like in appearance, and hover or arch over the plant, while the pointed, elongate fruit is of a helical form similar to that of the "tusk" of a narwhal. In the wild, species can be found growing on shaded rocky hillsides or

Gladiolus palustris, common name marsh gladiolus or sword lily, is a herbaceous perennial plant belonging to the genus Gladiolus of the family Iridaceae. The genus name Gladiolus is the Latin diminutive of gladius, a sword, while the specific Latin name palustris, meaning growing in marshes, refers to the alleged environment of this species.

Encyclia is also a Greek term for the Codex Encyclius Encyclia is a genus of orchids. The genus name comes from Greek enkykleomai ("to encircle"), referring to the lateral lobes of the lip which encircle the column. It is abbreviated as E. in the horticultural trade.

Amherstia nobilis (Burmese: သော်ကကြီး [θɔ̀ka̰ dʑí]; the Pride of Burma) is a tropical tree growing to about 15 metres (49 ft) in height with large, showy flowers. It is the only member of the genus Amherstia. It is widely cultivated for ornament in the humid tropics, but is extinct in the wild, only being known from a single wild specimen which was recorded in 1865. It is thus potentially endemic in Burma (Myanmar), hence the common name, though Plants of the World Online also cites it as native in adjoining Thailand. The scientific name commemorates Lady Amherst, (as does Lady Amherst's

Hydrangea paniculata, or panicled hydrangea, is a species of flowering plant in the family Hydrangeaceae native to southern and eastern China, Korea, Japan and Russia (Sakhalin). It was first formally described by Philipp Franz von Siebold in 1829.

The Cichorioideae are a subfamily of the family Asteraceae of flowering plants. Familiar members of Cichorioideae include lettuce, dandelions, chicory and Gazania species. The subfamily comprises about 240 genera and about 2900 species. It is heterogeneous and hard to characterize except with molecular characters.

Syzygium guineense (Bambara: Kokisa) is an evergreen leafy forest tree of the family Myrtaceae, found in many parts of Africa both wild and domesticated. Both its fruits and leaves are edible; the pulp and the fruit skin are sucked and the seed discarded. It is sometimes called "waterberry", but this may also refer to other species of Syzygium.

Chaenorhinum is a genus of flowering plants. It includes 27 species of annual and perennial herbs native to the Mediterranean Basin, Europe, and western Asia to the western Himalayas. They thrive in dry stony areas and scree. They are closely related to snapdragons. The leaves are linear to oblong or rounded, opposite at the base. The flowers resemble snapdragons, being typically zygomorphic, hooded, lobed and spurred. They are borne in terminal racemes or singly in the leaf axils of the branching stems.

Benthamia is a genus of orchids. It contains 29 recognized species, all native to Madagascar, Mauritius and Réunion.

Viola elatior, the fen violet, is a species of violet native to central and northern Europe and northern Asia. In the British Isles it is very rare, occurring in a few fens in England and near the western coast of Ireland. The violet is also known as viola persicifolia and viola stagnina.

For the clam genus, see Verticordia (bivalve). Verticordia is a genus of more than 100 species of plants commonly known as featherflowers, in the myrtle family, Myrtaceae. They range in form from very small shrubs such as V. verticordina to trees like V. cunninghamii, some spindly, others dense and bushy, but the majority are woody shrubs up to 2.0 m (7 ft) tall. The flowers are variously described as "feathery", "woolly" or "hairy" and are found in most colours except blue. They often appear to be in rounded groups or spikes but in fact are always single, each flower borne on a separate

Turneraceae Kunth ex DC. was a family of flowering plants consisting of 120 species in 10 genera. The Cronquist system placed the Turneracids in the order Violales, but it is not currently recognized as a family by the Angiosperm Phylogeny Group in the APG III system of 2009, which includes the taxa in the Turneraceae in Passifloraceae as a subfamily (Turneroideae).

Orobanche hederae, the ivy broomrape, is, like other members of the genus Orobanche, a parasitic plant without chlorophyll, and thus totally dependent on its host, which is ivy. It grows to 60 cm (2 ft), with stems in shades of brown and purple, sometimes yellow. The flowers are 10–22 mm (0.4–0.9 in) long, cream in colour with reddish-purple veins.

Mammillaria elongata, the gold lace cactus or ladyfinger cactus, is a species of flowering plant in the family Cactaceae, native to central Mexico. Growing to 15 cm (6 in) tall by 30 cm (12 in) wide, it consists of densely packed clusters of elongated oval stems, covered in harmless (although very sharp) yellow or brown spines, and in spring producing white or yellow flowers. It is among the most common and most variable of its genus in nature, and is a popular subject for cultivation. It has gained the Royal Horticultural Society's Award of Garden Merit.

Populus suaveolens, called the Mongolian poplar, Korean poplar and Japanese poplar, is a species of flowering plant in the genus Populus, native to all of northern Asia, the Korean peninsula, the Kurils, and northern Japan. It is a tree reaching 30 m.

Kunzea is a genus of plants in the family Myrtaceae and is endemic to Australasia. They are shrubs, sometimes small trees and usually have small, crowded, rather aromatic leaves. The flowers are similar to those of plants in the genus Leptospermum but differ in having stamens that are longer than the petals. Most kunzeas are endemic to Western Australia but a few occur in eastern Australia and a few are found in New Zealand. The taxonomy of the genus is not settled and is complicated by the existence of a number of hybrids.

Eritrichium (alpine forget-me-not) is a genus of flowering plants in the family Boraginaceae. It contains 78 species. Notable members include Eritrichium howardii and Eritrichium nanum. Its native range stretches from temperate Eurasia, across Alaska to the western central U.S. It is found in Europe (within Austria, France, Italy, Romania, Switzerland and Yugoslavia), in Siberia, (within Altay, Buryatiya, Chita, Krasnoyarsk and Tuva,) in Central Asia (within Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan), in Western Asia (within Afghanistan, East Himalaya, Iran, Pakistan and
