List of Saxifragales, Vitales and Zygophyllales families

From Wikipedia, the free encyclopedia
"flowers on a rock face"
Saxifraga, from Latin for "stone-breaking"[1][2]

Saxifragales, Vitales and Zygophyllales are three orders of flowering plants with a total of 18 families.[a] They belong to the superrosids, a group of around 150 related families, including the rose family. They are the only such orders that are not included in three large subgroups of the superrosids: the COM clade, the nitrogen-fixing clade and the malvids.[4][6][7][b]

The order Saxifragales includes fruit-bearing shrubs, woody vines, succulents, aquatics, and many ornamental trees and garden plants, including stonecrops, currants and witch-hazels.[4][8][9] Peonies are bred by horticulturists and widely cultivated in temperate gardens.[10] The antiseptic resin of sweetgum trees has been used as a balm since biblical times.[11] Cercidiphyllum japonicum, the largest tree species native to Japan, is used to make boards for the game of Go.[12] Redcurrants, rich in pectin, are used in jams and juices.[13]

Vitales and Zygophyllales include trees, shrubs, vines and herbaceous plants.[14] Krameria triandra is used as an astringent in mouthwash and toothpaste.[15] Wine, juices and jellies are made from grapes, and the leaves are also edible.[16] Guaiacum, in the twinleaf family, yields exceptionally hard lumber.[17]

Glossary

[edit]

From the glossary of botanical terms:

The APG IV system is the fourth in a series of plant taxonomies from the Angiosperm Phylogeny Group.[4]

Saxifragales is the only superrosid order that is not also a member of the rosids.[4][7] Although the Saxifragales families are quite diverse, there are a few visible traits that can be linked to many of them. The plants have relatively small seeds, except in the family Peridiscaceae.[19] Flowers tend to have separate, unfused petals, without nectar-secreting glands. The pollen-bearing anthers are often attached by their bases. Most fruits are follicles (seed pods). There are often two distinct ovaries, each with a hypanthium, a tube or cup-like structure in a flower that includes the bases of the sepals, petals, and stamens.[20]

Altingiaceae (sweetgum family) Liquidambar. Altingia, an earlier synonym, was named for Willem Arnold Alting (1724–1800), a Dutch colonial administrator.[34] 1 genus, in North America and southern, eastern and Southeast Asia[35][36] Evergreen and deciduous trees. Several species are harvested for timber. The wood of L. styraciflua is used to make furniture.[23][35][37]
Aphanopetala­ceae (gum-vine family) Aphanopetalum, from Greek for "inconspicuous petals"[38] 1 genus, in Australia[38][39] Shrubs, some twining like vines. The stems have extensive lenticels (ruptures in the bark) for gas exchange.[38]

Crassulaceae (stonecrop family) Crassula, from Latin for "little thick" (leaves)[44][45][46] 36 genera, scattered worldwide[47][48] Usually herbaceous perennials and annuals, sometimes shrubby, always with succulent stems. Some species of Crassula, Kalanchoe, Hylotelephium, Phedimus and Sempervivum are widely popular as potted ornamentals or rock garden plants. Sedum acre has been used as a pot-herb and a salad green.[47][31][49]
Cynomoriaceae (tarthuth family) Cynomorium, from Greek for "dog penis"[50] 1 genus, in arid regions near the Mediterranean and in central and eastern Asia[50][51] Reddish-brown herbaceous parasites, lacking chlorophyll. C. coccineum has been harvested in deserts for millennia for food and dyes.[50][52]
Daphniphylla­ceae (laurel-leaf family) Daphniphyllum, from Greek for "leaves like Daphne"[53][54] 1 genus, in southern, eastern and Southeast Asia[12][55] Unisexual evergreen shrubs and trees[12]
Grossularia­ceae (gooseberry family) Ribes. Grossularia, an earlier synonym, is from a Latin plant name.[56] 1 genus, in the temperate Northern Hemisphere and South America[56][57] Usually deciduous shrubs, frequently spiny. Most species have edible fruits. Blackcurrant, redcurrant and gooseberry fruits are mixed into juices, preserves and baked goods.[23][56][58]
