  • Mahonia × Media
    Mahonia × media Mahonia × media is an interspecific hybrid shrub. Its parents are Mahonia oiwakensis subsp. lomariifolia (previously known as Mahonia lomariifolia) and Mahonia japonica. It was raised in gardens during the 20th Century, and has become an important garden and landscape plant. Description The hybrids show some variation, but are generally intermediate in most characteristics between the two parents. The following description is of the clone 'Charity'. These are medium to large shrubs, reaching 4 m (13 ft) in height. The plants have an upright form, becoming bare at the base. There are between 7 and 11 pairs of leaflets, plus a terminal leaflet. The flowers are in somewhat spreading racemes, often as long as in M. japonica. There is some scent to the flowers, but it is not as strong as in M. japonica. Flowering goes on throughout the winter. Different clones may resemble one or the other parent more closely. It is possible that other species of Mahonia have contributed to the stock ascribed to this hybrid. Mahonia bealei is considered particularly likely to be one of these as it is often confused with Mahonia japonica.Many clones have an upright architectural form derived from M. oiwakensis subsp. lomariifolia, though some resemble the M. japonica parent rather more. Plants provide viable seed, and second generation hybrids have been raised. The plants are especially valued in the garden because of their ornamental leaves, and because they flower through the winter. Origin The first recorded plant was found in a mixed batch of seedlings from Mahonia oiwakensis subsp. lomariifolia that was raised in Northern Ireland in 1951 or earlier.

Brach Odostemon Rafinesque. Shrubs or small trees, evergreen, 0.3–8 m tall. Spines absent. Leaves imparipinnate, alternate, sessile or petiolate; petiole to 14 cm; leaflets 3–41; lateral leaflets usually sessile; terminal leaflet sessile or petiolulate; margins of leaflets entire, variously toothed, or with coarse or fine serrations. Inflorescence terminal, of (1–)3–18-fascicled simple or branched racemes or panicles, 3–35 cm, subtended by leafletlike bracts. Pedicel 1.5–24 mm, subtending bract shorter or longer than pedicel. Flowers yellow, with 3 whorls of sepals and 1 whorl of petals, with or without glands at base of petals. Anther connective not prolonged, apiculate or conspicuously prolonged. Ovary ellipsoid; ovules 1–7; styles absent or to 3 mm, persistent on mature fruit. Fruit berries, bluish or black, often glaucous. Seeds 1–7. About 60 species: mainly in E and SE Asia, also in W North America, Central America, and W South America; 31 species (27 endemic) in China; six additional species (five endemic) are insufficiently known. Most of the Chinese wild populations of Mahonia have been extirpated, probably as a result of over-collecting for medicinal use, and the plants now being described are probably individuals that vary only in minor ways from the relatively few specimens that exist in herbaria. Ahrendt (J. Linn. Soc., Bot. 57: 1–410. 1961) recognized two “groups” in Mahonia: “Orientales” and “Occidentales.” All of the Asian species of Mahonia, plus a single North American species from the Pacific Northwest, M.

  • ABSTRACT ROUNSAVILLE, TODD JEFFREY. Cytogenetics
    ABSTRACT ROUNSAVILLE, TODD JEFFREY. Cytogenetics, Micropropagation, and Reproductive Biology of Berberis, Mahonia, and Miscanthus. (Under the direction of Thomas G. Ranney). Research was conducted to determine the genome sizes and ploidy levels for a diverse collection of Berberis L. and Mahonia Nutt. genotypes, develop a micropropagation protocol for Mahonia „Soft Caress‟, and examine the fertility and reproductive pathways among clones of diploid and triploid Miscanthus sinensis Andersson. Berberis and Mahonia are sister taxa within the Berberidaceae with strong potential for ornamental improvement. Propidium iodide (PI) flow cytometric analysis was conducted to determine genome sizes. Mean 1CX genome size varied between the two Mahonia subgenera (Occidentales = 1.17 pg, Orientales = 1.27 pg), while those of Berberis subgenera were similar (Australes = 1.45 pg, Septentrionales = 1.47 pg), but larger than those of Mahonia. Traditional cytology was performed on representative species to calibrate genome sizes with ploidy levels. While the majority of species were determined to be diploid with 2n = 2x = 28, artificially-induced autopolyploid Berberis thunbergii seedlings were confirmed to be tetraploid and an accession of Mahonia nervosa was confirmed to be hexaploid. Genome sizes and ploidy levels are presented for the first time for the majority of taxa sampled and will serve as a resource for plant breeders, ecologists, and systematists. Mahonia „Soft Caress‟ is a unique new cultivar exhibiting a compact form and delicate evergreen leaves, though propagation can be a limiting factor for production. Micropropagation protocols for M. „Soft Caress‟ were developed to expedite multiplication and serve as a foundation for future work with other Mahonia taxa.

It flowers from mid April to May in the Northeast and its fruits mature from July to October. The branches are glabrous, deeply grooved, brown and have usually simple spines. The leaves are glaucescent underneath, spatulate or narrowly obovate in shape, and are 1.3-3.8 cm (0.5-1.5 in.) long. They range in color from slightly bluish-green to green to dark reddish purple. The pale yellow flowers of Berberis thunbergii are profuse and located along the entire length of the stem.

The 1978 Act of the International Convention for the Protection of New Varieties of Plants is applicable, according to its Article 4(1), to all botanical genera and species. Its Article 4(2) provides that “the member States of the Union undertake to adopt all measures necessary for the progressive application of the provisions of this Convention to the largest possible number of botanical genera and species.” The 1991 Act of the Convention provides in its Article 3 that “each Contracting Party which is bound by the Act of 1961/1972 or the Act of 1978 shall apply the provisions of this Convention, (i) at the date on which it becomes bound by this Convention, to all plant genera and species to which it applies, on the said date, the provisions of the Act of 1961/1972 or the Act of 1978 and, (ii) at the latest by the expiration of a period of five years after the said date, to all plant genera and species,” and that “each Contracting Party which is not bound by the Act of 1961/1972 or the Act of 1978 shall apply the provisions of this Convention, (i) at the date on which it becomes bound by this Convention, to at least 15 plant genera or species and, (ii) at the latest by the expiration of a period of 10 years from the said date, to all plant genera and species.” 2.
