James L. Reveal

U.s. botanist (1941–2015).

James Lauritz Reveal (March 29, 1941 – January 9, 2015) was a U.S. botanist best known for his contributions to the genus Eriogonum and for his work on suprageneric names. His website, at PlantSystematics.org, also presents material on plant taxonomy including the Reveal system. He published extensively on North American flora, was a member of the Angiosperm Phylogeny Group, and was one of the authors of the APG II and APG III classifications. At the time of his death, Reveal was a professor emeritus at the University of Maryland, adjunct professor at Cornell University's Department of Plant B

Pinophyta (Coniferae) Cronquist, Takht. & W.Zimm. ex Reveal 1996
plant phylum
Conifers are a group of vascular plants and a subset of gymnosperms. They are primarily perennial, woody trees and shrubs, mostly evergreen with a regular branching pattern, reproducing with male and female cones, usually on the same tree. They are wind-pollinated and the seeds are usually dispersed by the wind. Taxonomically, they make up the division Pinophyta, also known as Coniferae. All extant conifers, except for the gnetophytes, are perennial woody plants with secondary growth. There are over 600 living species. Conifers first appear in the fossil record over 300 million years ago in
Austrobaileyales (Austrobaileya) Takht. ex Reveal
plant order in the class magnoliopsida
Austrobaileyales is an order of flowering plants consisting of about 100 species of woody plants growing as trees, shrubs and lianas. A well known example is Illicium verum, commonly known as star anise. The order belongs to the group of basal angiosperms, the ANA grade (Amborellales, Nymphaeales, and Austrobaileyales), which diverged earlier from the remaining flowering plants. Austrobaileyales is sister to all remaining extant angiosperms outside the ANA grade. The order includes just three families of flowering plants: the Austrobaileyaceae, a monotypic family containing the sole genus,
Crossosomatales (Bladdernuts) Takht. ex Reveal 1993
plant order in the class magnoliopsida
The Crossosomatales are an order, first recognized as such by APG II. They are flowering plants included within the Rosid eudicots.
Gunnerales (Gunneras And Resurrection Plants) Takht. ex Reveal
plant order in the class magnoliopsida
The Gunnerales are an order of flowering plants. In the APG III (2009) and APG IV systems (2016), the order contains two genera: Gunnera (family Gunneraceae) and Myrothamnus (Myrothamnaceae). In the Cronquist system (1981), the Gunneraceae were in the Haloragales and Myrothamnaceae in the Hamamelidales. DNA analysis proved definitive, but the grouping of the two families was a surprise, given their very dissimilar morphologies. In the older systems of Cronquist (1981, 1988) and Takhtajan (1997), the Gunneraceae were in the Rosidae, and the Myrothamnaceae were in the Hamamelids. In modern
Buxales (Boxes And Pachysandras) Takht. ex Reveal 1996
plant order in the class magnoliopsida
The Buxales are a small order of eudicot flowering plants, recognized by the APG IV system of 2016. The order includes the family Buxaceae; the families Didymelaceae and Haptanthaceae may also be recognized or may be included in the Buxaceae. Many members of the order are evergreen shrubs or trees, although some are herbaceous perennials. They have separate "male" (staminate) and "female" (carpellate) flowers, mostly on the same plant (i.e. they are mostly monoecious). Some species are of economic importance either for the wood they produce or as ornamental plants.
Schlegeliaceae (Schlegelia Family) Reveal 1996
plant family in the order lamiales
Schlegeliaceae is a family of plants native to tropical America. This family is sometimes included in Scrophulariaceae.
Lophiocarpaceae (Lophiocarpus Family) Doweld & Reveal 2008
plant family in the order caryophyllales
The Lophiocarpaceae are a family of flowering plants comprising mostly succulent subshrubs and herbaceous species native to tropical to southern sub-Saharan Africa to western India. It includes the genera Corbichonia and Lophiocarpus. The family is newly recognized through research by the Angiosperm Phylogeny Group III system to deal with long-standing phylogenetic difficulties in placing various genera within the Caryophyllales.
Centroplacaceae (Centroplacus Family) Doweld & Reveal 2005
plant family in the order malpighiales
Centroplacaceae is a family of flowering plants in the order Malpighiales and is recognized by the APG III system of classification. The family comprises two genera: Bhesa, which was formerly recognized in the Celastraceae, and Centroplacus, which was formerly recognized in the Euphorbiaceae, together comprising six species. The Angiosperm Phylogeny Group determined that based on previous phylogenetic analysis, these two genera formed an isolated clade and recognition of the family was "reasonable."
Mazaceae (Mazus Family) Reveal 2011
plant family in the order lamiales
Mazaceae is a family of plants in the order Lamiales. The family was described by James L. Reveal in 2011. Genera in this family were most recently previously included in Phrymaceae and in older classifications were placed in Scrophulariaceae. Plants of the World Online includes four genera: Dodartia Tourn. ex L. Lancea Hook.f. & Thomson Mazus Lour. Puchiumazus Bo Li, D.G.Zhang & C.L.Xiang Germplasm Resources Information Network includes only Lancea and Mazus. The Angiosperm Phylogeny Website includes Dodartia, Lancea, and Mazus.

Asteropeiaceae (Asteropeia Family) (Szyszył.) Takht. ex Reveal & Hoogland 1990
plant family in the order caryophyllales
"Asteropeia" may also refer to a figure in Greek mythology, see Antinoe Asteropeia is a genus of flowering plants. The genus contains 8 known species of shrubs and small trees, all endemic to Madagascar. It is the sole genus in family Asteropeiaceae. Members of the family are evergreen trees or shrubs. Members of the family were separated from the Theaceae based on wood anatomy by the APG system of 1998, and assigned to the order Caryophyllales in the clade core eudicots. The family consists of a single genus, Asteropeia, native to Madagascar. According to the AP-Website it forms a clade
Lomandroideae (Cabbage Tree Subfamily) Thorne & Reveal 2007
plant subfamily in the asparagaceae family
Lomandroideae is a subfamily of monocot flowering plants in the family Asparagaceae, order Asparagales, according to the APG III system of 2009. The subfamily name is derived from the generic name of the type genus, Lomandra. The group has previously been treated as a separate family Laxmanniaceae. In the Kubitzki system, it is treated as Lomandraceae Lotsy. The subfamily consists of some 15 genera and about 180 species from Australasia, southeast Asia, the Americas and the Pacific Islands. The best-known genus is Cordyline.

The genus Limeum was traditionally recognized as belonging to the family Molluginaceae, but is now treated as the sole genus in the monotypic family Limeaceae. The family is newly recognized through research by the Angiosperm Phylogeny Group III system to deal with long-standing phylogenetic difficulties in placing various genera within the Caryophyllales. Limeum comprises subshrub and herbaceous species native to tropical, eastern and southern Africa, and South Asia. Previously, the genus Macarthuria from Australia was also
