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]
Maianthemum includes the former genus Smilacina and is a genus of perennial herbaceous flowering plants with fleshy, persistent rhizomes. It is widespread across much of North America, Europe and Asia, and may be terrestrial, aquatic or epiphytic. It is characterized by simple, unbranched stems that are upright, leaning or hanging down and have 2–17 foliage leaves. Leaves are simple and may clasp the stem or be short-petiolate. The inflorescence is terminal and either a panicle or a raceme with few to many pedicelate flowers. Most species have 6 tepals and 6 stamens; a few have parts in 4s. Tepals are distinct in most species and all of similar size. Flowers are spreading, cup-shaped or bell-shaped and usually white, but lavender to red or green in some species. Fruits are rounded to lobed berries containing few to several seeds.
Ulmus crassifoliaNutt., the Texas cedar elm or simply cedar elm, is a deciduous tree native to south-central North America, mainly in southern and eastern Texas, southern Oklahoma, Arkansas, and Louisiana, with small populations in western Mississippi, southwest Tennessee, and north-central Florida; it also occurs in northeastern Mexico. It is the most common elm tree in Texas. The tree typically grows well in flat valley bottom areas referred to as cedar elm flats. Its Latin name refers to its comparatively thick (crassifoliate) leaves; the common name cedar elm is derived from the trees' association with juniper trees, locally known as cedars.
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, Brittany, and south-west Ireland, until the arrival of Dutch elm disease in the late 1960s. The origin of Cornish elm in the south-west of Britain 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.
The field elm cultivar Ulmus minor 'Plotii', commonly known as Lock elm or Lock's elm, Plot's elm or Plot elm, and first classified as Ulmus sativaMill. var. Lockii and later as Ulmus plotii by Druce in 1907-11, is endemic mainly to the East Midlands of England, notably around the River Witham in Lincolnshire, in the Trent Valley around Newark-on-Trent, and around the village of Laxton, Northamptonshire. Ronald Melville suggested that the tree's distribution may be related to river valley systems, in particular those of the Trent, Witham, Welland, and Nene. Two further populations existed in Gloucestershire. It has been described as Britain's rarest native elm, and recorded by The Wildlife Trust as a nationally scarce species.
Stylidium laricifolium, commonly known as giant trigger-plant, larch-leaf or tree triggerplant, or is a species of flowering plant in the family Stylidiaceae and is endemic to eastern Australia. It is a perennial subshrub with many linear leaves crowded along its few stems, the flowers white to pale pink and arranged in a single main panicle and smaller racemes.
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.
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, ranging 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.
Syzygium ingens, commonly known as red apple, is a species of flowering plant that is endemic to eastern Australia. It is a medium-sized to tall rainforest tree with narrow elliptic to oblong leaves and panicles of white flowers on the ends of branchlets, followed by spherical red berries.
Cassinia uncata, commonly known as sticky cassinia, is a species of flowering plant in the family Asteraceae and is native to inland New South Wales and the south-east of South Australia. It is an erect shrub with hairy young stems, narrow linear to needle-shaped leaves, and heads of off-white to cream-coloured flowers arranged in rounded, almost conical panicles.
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 2,890–3,450 m (9,480–11,320 ft) in the fir and hemlock forests. It is called Tala (ཏ་ལ) in Dzongkha. It is a large shrub or tree that typically grows to 15 m (49 ft) in height, with leaves that are broadly elliptic to almost obovate, and 20–30 cm (7.9–11.8 in) long by 10–16 cm (3.9–6.3 in) broad. The flowers are rose pink, fading to purple.
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 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.
