Rhododendron is the largest genus in the family Ericaceae, with as many as 1,024 species, (though estimates vary from 850-1000) and is morphologically diverse. The large number of species that were available by the early twentieth century prompted a new approach when Balfour introduced the concept of grouping species into series. Vireya ندارد. Rhododendron vireya 'Saxon Glow' (PVR) Lovely miniature vireya that is covered for most of the year with richly coloured salmon-pink blooms. Veldkamp, L.A. Goetsch, B.D. [30][31] In 1986 Philipson & Philipson raised two sections of subgenus Aleastrum (Mumeazalea, Candidastrum) to subgenera, while reducing genus Therorhodion to a subgenus of Rhododendron. Os rododendros [1] son arbustos pertencentes ao xénero Rhododendron (do grego: rhodos, rosa; dendron, árbore). Most species have brightly colored flowers which bloom from late winter through to early summer.[6]. Hall. Larger commercial growers often ship long distances; in the United States, most of them are on the west coast (Oregon, Washington state and California). [2], Rhododendron are characterised by having inflorescences with scarious (dry) perulae, a chromosome number of x=13, fruit that has a septicidal capsule, an ovary that is superior (or nearly so), stamens that have no appendages, and agglutinate (clumped) pollen. Meanwhile, other botanists such as Salisbury (1796)[19] and Tate (1831)[20] began to question the distinction between Azalea and Rhododendron, and finally in 1836, Azalea was incorporated into Rhododendron[21] and the genus divided into eight sections.

[citation needed], In the language of flowers, the Rhododendron symbolizes danger and to beware.[77]. The species in New Guinea are native to subalpine moist grasslands at around 3,000 metres above sea level in the Central Highlands. [49], Rhododendron bud blast, a fungal condition that causes buds to turn brown and dry, and not open, is caused by the fungus Pycnostysanus azaleae, which may be brought to the plant by the rhododendron leafhopper, Graphocephala fennahi.[50](p562). Yes, it does! Classification. The next two smaller subgenera (Pentanthera and Tsutsusi) represent the 'Azaleas'. Later Gao et al. Blumea 53: 435–442. Azaleas make up two subgenera of Rhododendron. Also, I sometimes notice some of the green leaves partially go brown. Half hardy 0.6 x 0.6m. Of the remaining three sections, monotypic Viscidula was discontinued by moving Rhododendron nipponicum to Tsutsusi (C), while Rhodora (2 species) was itself polyphyletic and was broken up by moving Rhododendron canadense to section Pentanthera (B) and Rhododendron vaseyi to section Sciadorhodion, which then became a new section of subgenus Azaleastrum (C).

Sleumer based his system on the relationship of the flower buds to the leaf buds, habitat, flower structure, and whether the leaves were lepidote or non-lepidote. The rootstock is able to grow in calcium-rich soil up to a pH of 7.5. Vireyas are native to southeastern Asia and range from Thailand to Australia. The four sections of Pentanthera between clades B and C, with two each, while Azaleastrum had one section in each of A and C. Thus subgenera Azaleastrum and Pentanthera needed to be disassembled, and Rhododendron, Hymenanthes and Tsutsusi correspondingly expanded. Care.

[1] For a fuller story on the Jury vireyas, go to The Jury Vireya Legacy, written for and published by the RHS in 2012. This genus has been progressively subdivided into a hierarchy of subgenus, section, subsection, and species. [51] Azaleas are frequently used around foundations and occasionally as hedges, and many larger-leafed rhododendrons lend themselves well to more informal plantings and woodland gardens, or as specimen plants. (2005) Table 1.[2]. Vireya rhododendrons. In all, Hymenanthes increased from one to two sections, while Azaleastrum, by losing one section and gaining two increased from two to three sections. 2011. Known for their brilliant colour, vireyas are the star of the rhododendron family, often flowering all year round. Consequently, the taxonomy has been historically complex. By contrast subgenera Azaleastrum and Pentanthera were polyphyletic, while R. camtschaticum appeared as a sister to all other rhododendrons. [2], Vireya are morphologically diverse, and characterised by seeds with tailed appendages, the presence of leaf idioblasts and capsule valves which twist upon opening.[4]. The Species of Rhododendron[26] referred to this series concept as the Balfourian system.

This structure largely survived till recently (2004), following which the development of molecular phylogeny led to major re-examinations of traditional morphological classifications,[16][17] although other authors such as Candolle, who described six sections,[22] used slightly different numeration. Vireyas are native to southeastern Asia and range from Thailand to Australia.. Vireya are morphologically diverse, and characterised by seeds with tailed appendages, the presence of leaf idioblasts and capsule valves which twist upon opening. Sleumer's system underwent many revisions by others, predominantly the Edinburgh group in their continuing Royal Botanic Garden Edinburgh notes. The formal description (Craven 2008) is: Scales sessile or sometimes stalked, lobed to deeply incised or sometimes entire; corolla campanulate, trumpet-like, salver-shaped, tubular or funnel-shaped; stamens (5–)10(–16), exserted to included, staminal filaments glabrous or hairy from the base; capsule valves twisting after dehiscence; seeds with a distinct tail at each end.

A number of insects either target rhododendrons or will opportunistically attack them. R. ponticum is difficult to eradicate, as its roots can make new shoots. The love affair here with the somewhat exotic genus of vireya rhododendrons can be traced back to Felix Jury’s intrepid plant hunting trip to New Guinea in 1957. Major speciation accompanied the dispersal of Vireya Rhododendrons (Ericaceae, Rhododendron sect.

Later, it was recognized that honey resulting from these plants has a slightly hallucinogenic and laxative effect. They are distinguished from "true" rhododendrons by having only five anthers per flower. Many hybrids have been produced, some are very fragrant, and most are ideal for container growing on a balcony, on (or under) a tree, or in a shadehouse.… Thus Craven et al.

The next major attempt at classification was by Sleumer who from 1934 began incorporating the Balfourian series into the older hierarchical structure of subgenera and sections, according to the International Code of Botanical Nomenclature, culminating in 1949 with his "Ein System der Gattung Rhododendron L.",[28] and subsequent refinements. Subgenus Pentanthera (deciduous azaleas) with its four sections was dismembered by eliminating two sections and redistributing the other two between the existing subgenera in clades B (Hymenanthes) and C (Azaleastrum), although the name was retained in section Pentanthera (14 species) which was moved to subgenus Hymenanthes. Native to mountainous jungles of the Malay-Indonesian archipelago, they have a dark history and have been almost lost to plant lovers since World War I. Revisions by Goetsch et al.

Like other ericaceous plants, most rhododendrons prefer acid soils with a pH of roughly 4.5–5.5; some tropical Vireyas and a few other rhododendron species grow as epiphytes and require a planting mix similar to orchids. [37] Finally Chamberlain brought the various systems together in 1996, with 1,025 species divided into eight subgenera. In addition, rhododendrons can easily be suffocated by other plants or evergreen trees that grow up around them and block sunlight. Hall, B.D., L.A. Craven & L.A. Goetsch.
