Isodon atroruber is a species of flowering plant endemic to Bhutan. It differs from other species of Isodon in having deep wine red flowers in narrow panicles. [1]
Isodon atroruber is a perennial herb with stems growing to around 50 cm. Stems little branched and four angled, glandular hairy. Leaves ovate, acuminate, base rounded-truncate with the lamina slightly decurrent on petiole. Leaf margin serrate-dentate. Upper surface of the leaves glandular-pubescent while the lower surface has villous hairs on veins. Inflorescence is a narrow panicle with deep wine red to deep reddish-purple corolla. Nutlets are ellipsoid and pale brown in color. [2]
The holotype was collected by Grierson & Long from Dotena in Thimphu district, Bhutan on 5 September 1984. The place is located at an elevation of 2550m from the sea level. The type specimen is currently held at the Herbarium, Royal Botanic Garden Edinburgh with catalogue number E00273726. [3]
Ulmus thomasii, the rock elm or cork elm, is a deciduous tree native primarily to the Midwestern United States. The tree ranges from southern Ontario and Quebec, south to Tennessee, west to northeastern Kansas, and north to Minnesota.
Ulmus davidiana var. japonica, the Japanese elm, is one of the larger and more graceful Asiatic elms, endemic to much of continental northeast Asia and Japan, where it grows in swamp forest on young alluvial soils, although much of this habitat has now been lost to intensive rice cultivation.
Nepenthes papuana is a tropical pitcher plant endemic to New Guinea. The specific epithet papuana is derived from Papua, an alternative name for the island.
The field elm cultivar Ulmus minor 'Stricta', known as Cornish elm, was commonly found in South West England and Brittany until the arrival of Dutch elm disease in the late 1960s. The origin of Cornish elm in England remains a matter of contention. It is commonly assumed to have been introduced from Brittany. It is also considered possible that the tree may have survived the ice ages on lands to the south of Cornwall long since lost to the sea. Henry thought it "probably native in the south of Ireland". Dr Max Coleman of Royal Botanic Garden Edinburgh, arguing in his 2002 paper on British elms that there was no clear distinction between species and subspecies, suggested that known or suspected clones of Ulmus minor, once cultivated and named, should be treated as cultivars, preferred the designation U. minor 'Stricta' to Ulmus minor var. stricta. The DNA of 'Stricta' has been investigated and the cultivar is now known to be a clone.
Aeonium arboreum, the tree aeonium, tree houseleek, or Irish rose, is a succulent, subtropical subshrub in the flowering plant family Crassulaceae.
Nepenthes jamban is a tropical pitcher plant endemic to northern Sumatra. The specific epithet jamban is the Indonesian word for "toilet" and refers to the shape of the pitchers.
Ulmus minorsubsp.canescens is a small deciduous tree occasionally known by the common names grey elm, grey-leafed elm, and hoary elm. Its natural range extends through the lands of the central and eastern Mediterranean, from southern Italy, the islands of Sicily, Malta, Crete, Rhodes and Cyprus, to Turkey, and as far south as Israel, where it is now considered rare and endangered in the wild. The tree is typically found amidst the comparatively humid coastal woodlands and scrublands.
Ulmus minor 'Rueppellii' is a Field Elm cultivar said to have been introduced to Europe from Tashkent by the Späth nursery, Berlin. Noted in 1881 as a 'new elm', it was listed in Späth Catalogue 73, p. 124, 1888–89, and in subsequent catalogues, as Ulmus campestris Rueppelli, and later by Krüssmann as a cultivar.
The elm Ulmus wallichiana subsp. xanthoderma was identified by Melville and Heybroek after the latter's expedition to the Himalaya in 1960. The tree is of more western distribution than subsp. wallichiana, from Afghanistan to Kashmir.
Acradenia euodiiformis, commonly known as yellow satinheart or bonewood, is a species of tree that is endemic to eastern Australia. It has mostly trifoliate leaves, the leaflets narrow elliptic to lance-shaped, with prominent oil glands, and panicles of white flowers. It grows in and near rainforest.
Ulmus × hollandica 'Wentworthii Pendula', commonly known as the Wentworth Elm or Wentworth Weeping Elm, is a cultivar with a distinctive weeping habit that appears to have been introduced to cultivation towards the end of the 19th century. The tree is not mentioned in either Elwes and Henry's or Bean's classic works on British trees. The earliest known references are Dutch and German, the first by de Vos in Handboek tot de praktische kennis der voornaamste boomen (1890). At about the same time, the tree was offered for sale by the Späth nursery of Berlin as Ulmus Wentworthi pendulaHort.. The 'Hort.' in Späth's 1890 catalogue, without his customary label "new", confirms that the tree was by then in nurseries as a horticultural elm. De Vos, writing in 1889, states that the Supplement to Volume 1 includes entries announced since the main volume in 1887, putting the date of introduction between 1887 and 1889.
Eremophila graciliflora, commonly known as slender-flowered eremophila, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. It is a shrub with linear to lance-shaped leaves and red flowers known only from the type specimen collected by Augustus Oldfield and held at the State Botanical Collection at Royal Botanic Gardens in Melbourne, so that a living example has not been recorded for more than 150 years.
Rhododendron kesangiae is a rhododendron species endemic to Bhutan, where it grows at altitudes of 2890–3450 meters in the Fir and Hemlock forests. It is called Tala (ཏ་ལ) in Dzongkha. It is a tree that typically grows to 15 meters in height, with leaves that are broadly elliptic to almost obovate, and 20-30 x 10–16 cm in size. Flowers are rose pink, fading to purple.
The Field Elm cultivar Ulmus minor 'Viminalis' (:'willow-like'), occasionally referred to as the Twiggy Field Elm, was raised by Masters in 1817, and listed in 1831 as U. campestris viminalis, without description. Loudon added a general description in 1838, and the Cambridge University Herbarium acquired a leaf specimen of the tree in 1866. Moss, writing in 1912, said that the Ulmus campestris viminalis from Cambridge University Herbarium was the only elm he thought agreed with the original Plot's elm as illustrated by Dr. Plot in 1677 from specimens growing in an avenue and coppice at Hanwell near Banbury. Elwes and Henry (1913) also considered Loudon's Ulmus campestris viminalis to be Dr Plot's elm. Its 19th-century name, U. campestris var. viminalis, led the cultivar to be classified for a time as a variety of English Elm. On the Continent, 'Viminalis' was the Ulmus antarcticaHort., 'zierliche Ulme' [:'dainty elm'] of Kirchner's Arboretum Muscaviense (1864).
Chiloglottis trapeziformis, commonly known as the broad-lip bird orchid, diamond ant orchid or dainty bird-orchid, is a species of orchid endemic to south-eastern Australia. It has two narrow leaves and a narrow, greenish to purplish or brownish flower with a short, shiny black, ant-like callus covering the lower quarter of the diamond-shaped labellum. It has been recorded as a vagrant in New Zealand.
Protea effusa, sometimes known as the scarlet sugarbush, is a flowering plant which belongs to the genus Protea. The plant is endemic to the Western Cape province of South Africa. In the Afrikaans language the vernacular name blosrooisuikerbos has been recorded for this plant.
Protea intonsa, also known as the tufted sugarbush, is a flowering plant of the genus Protea within the family Proteaceae, endemic to South Africa, where it is distributed from the eastern Swartberg and Kammanassie Mountains to the Baviaanskloof mountains. In Afrikaans it is known as klossie-suikerbos.
Protea montana also known as the Swartberg sugarbush, is a flowering plant of the genus Protea within the family Proteaceae, which is endemic to the southwestern Cape Region of South Africa. In Afrikaans it is known as swartbergsuikerbos.
Eulophia stenopetala is a species of orchid endemic to Bhutan. The only material on this species from Bhutan is the holotype specimen collected by William Griffith in Bhutan in 1838 and resides at the Kew Herbarium with catalogue number K000852991. Another specimen without any information on its location is also available at the Naturalis Biodiversity Center with catalogue number U.1466607. The plant is currently considered extinct as numerous attempts to find it in the type locality failed.
Piper sylvaticum is a climber in the Piperaceae, or pepper, family. It is found in the northeast of the Indian subcontinent, and in Zhōngguó/China. The fruits are used in medicinal products.
