Rosularia is a small genus of the family Crassulaceae. It includes about 28-35 species from Europe, the Himalayas, and northern Africa.
Rosularia was originally described by De Candolle (1828) as a section of the genus Umbilicus, [2] and raised to the level of genus by Stapf (1923) [3] Thus the genus bears the botanical authority (DC) Stapf of both authors. [1]
In 1930 Berger included it in family Crassulaceae subfamily Sedoideae, as one of 9 genera. [4] [5] He further divided it into two sections (Eu-Rosularia and Ornithogalopsis) and further series, [6] transferring some species of Sedum to it. Since then a number of species have been transferred in and out of the genus, including S. sempervivoides, which at one stage was placed in Prometheum . [5] The genus Sempervivella was submerged in Rosularia. [6] The genus is now placed within the Leucosedum clade, tribe Sedeae, subfamily Sempervivoideae of the Crassulaceae, but is embedded within Sedum paraphyletically. [7] [1] [8]
Rosularia contains about 28 species. The following species and subspecies were accepted by The Plant List (2013): [9] [10]
Rosularia is found in arid and semi-arid regions from N. Africa (Morocco, Ethiopia), through the eastern Mediterranean to Central Asia (north of Tien Shan and east of W Himalaya), including Pakistan. [6] [5]
Rosularia is an important larval host for the Central Asian butterfly Parnassius apollonius . [12]
A number of species are cultivated as ornamental garden plants, and have been used in traditional medicine. [5]
The Crassulaceae, also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus Sedum, and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic.
Sedum is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. The genus has been described as containing up to 600 species, subsequently reduced to 400–500. They are leaf succulents found primarily in the Northern Hemisphere, but extending into the southern hemisphere in Africa and South America. The plants vary from annual and creeping herbs to shrubs. The plants have water-storing leaves. The flowers usually have five petals, seldom four or six. There are typically twice as many stamens as petals. Various species formerly classified as Sedum are now in the segregate genera Hylotelephium and Rhodiola.
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.
Prometheum is a genus of plants in the family Crassulaceae.
Umbilicus is a genus of over ninety species of flowering plants in the family Crassulaceae. Many of its species have been given synonyms under different genera such as Rosularia, Cotyledon, and Chiastophyllum. However, those that remain in Umbilicus are listed below:
Arenaria is a genus of flowering plants, within the family Caryophyllaceae.
Hylotelephium telephium, known as orpine, livelong, frog's-stomach, harping Johnny, life-everlasting, live-forever, midsummer-men, Orphan John and witch's moneybags, is a succulent perennial groundcover of the family Crassulaceae native to Eurasia. The flowers are held in dense heads and can be reddish or yellowish-white. A number of cultivars, often with purplish leaves, are grown in gardens as well as hybrids between this species and the related Hylotelephium spectabile (iceplant), especially the popular 'Herbstfreude'. Occasionally garden plants may escape and naturalise as has happened in parts of North America.
Rhodiola is a genus of perennial plants in the family Crassulaceae that resemble Sedum and other members of the family. Like sedums, Rhodiola species are often called stonecrops. Some authors merge Rhodiola into Sedum.
Phedimus spurius, the Caucasian stonecrop or two-row stonecrop, is a species of flowering plant in the family Crassulaceae. It is still widely listed in the literature as Sedum spurium.
Hylotelephium is a genus of flowering plants in the stonecrop family Crassulaceae. It includes about 33 species distributed in Asia, Europe, and North America.
AnacampserosL. is a genus comprising about a hundred species of small perennial succulent plants native to Southern Africa, Ethiopia and Latin America. The botanical name Anacampseros is an ancient one for herbs supposed to restore lost love.
Aizopsis is a genus of the succulent family Crassulaceae, found in east Asia.
Petrosedum is a genus of the succulent family Crassulaceae.
Phedimus is a genus of the succulent family Crassulaceae, with about 18 species, distributed in eastern Europe and Asia. The genus is described with two subgenera, but one of these is also recognized as a separate genus, Aizopsis. Phedimus kamtschaticus is widely grown as an ornamental ground cover and has gained the Royal Horticultural Society's Award of Garden Merit.
Orostachys is a genus of the succulent family Crassulaceae that contains about 15 species. It is a biennial herb growing in China, Japan, Kazakhstan, Korea, Mongolia, Russia. Eight species occur in China.
Pseudosedum is a genus of flowering plants in the family Crassulaceae.
Sempervivoideae is the largest of three subfamilies in the Saxifragales family Crassulaceae, with about 20–30 genera with succulent leaves. Unlike the two smaller subfamilies, it is distributed in temperate climates. The largest genus in this subfamily is Sedum, with about 470 species.
Chaloupkaea is a genus of flowering plants belonging to the family Crassulaceae.
