Caltha appendiculata is a perennial herb plant found in several countries of South America.
Caltha appendiculata is a low (2½-7 cm high) dioecious, perennial herb, often growing in dense clusters over considerable areas, with thick rhizomes. The strong stems are sparingly branched, somewhat elongated, and covered by the remains of old sheaths. Its thick and fleshy leaves consist of a short leafstalk and a blade of between six and ten mm long, which is ovate, elliptical or oblong in outline, has an entire margin or is split into three lobes, and usually is retuse at the tip. Near the midrib on the upward leaf face are two or three narrow leaflike outgrowths. This makes the leaf blade in its entirety reminiscent of an opened book. These appendages are in fact homologous with the ears at the base of the leaf blade of Northern Hemisphere Caltha species.
The faintly sweet scented actinomorphic solitary flowers of between one and two cm across have five spreading, lanceolate, pale yellow to creamy-green sepals with a purplish margin, and which are gradually narrowing towards the tip. Male flowers have thick, grooved peduncles. There are usually nine stamens. The five ovaries do not develop seeds. Female flowers have rudimentary staminodes, and five to nine compressed ovaries, with a papillose exterior. The carpels each contain up to seven or eight ovules, of which usually one or two develop into pale brown, shiny seeds. Flowers are present from late spring to summer. There are forty eight chromosomes (2n=48). [1] [2] [3]
The species occurs on the Hermite Islands, the Falklands, Tierra del Fuego and the Southern Andes, in trickling melt water, marshes and other wet areas, from sea level up to about 2000 m. [2]
Caltha palustris, known as marsh-marigold and kingcup, is a small to medium sized perennial herbaceous plant of the buttercup family, native to marshes, fens, ditches and wet woodland in temperate regions of the Northern Hemisphere. It flowers between April and August, dependent on altitude and latitude, but occasional flowers may occur at other times.
Caltha is a genus of rhizomatous perennial flowering plants in the family Ranunculaceae, to which ten species have been assigned. They occur in moist environments in temperate and cold regions of both the Northern and Southern Hemispheres. Their leaves are generally heart-shaped or kidney-shaped, or are characteristically diplophyllous. Flowers are star shaped and mostly yellow to white. True petals and nectaries are missing but the five or more sepals are distinctly colored. As usual in the buttercup family there is a circle of stamens around free carpels.
This page provides a glossary of plant morphology. Botanists and other biologists who study plant morphology use a number of different terms to classify and identify plant organs and parts that can be observed using no more than a handheld magnifying lens. This page provides help in understanding the numerous other pages describing plants by their various taxa. The accompanying page—Plant morphology—provides an overview of the science of the external form of plants. There is also an alphabetical list: Glossary of botanical terms. In contrast, this page deals with botanical terms in a systematic manner, with some illustrations, and organized by plant anatomy and function in plant physiology.
Paeonia obovata is a perennial herbaceous species of peony growing 30–70 cm high. It has white, pink or purple-red flowers and its lower leaves consist of no more than nine leaflets or segments. In English it is sometimes called woodland peony. It grows naturally in warm-temperate to cold China, including Manchuria, and in Korea, Japan, Far Eastern Russia and on Sakhalin.
Caltha leptosepala, the white marsh marigold, twinflowered marsh marigold, or broadleaved marsh marigold, is a North American species of flowering plant in the buttercup family. The species has regionally distinct variations.
Paeonia veitchii is a species of herbaceous perennial peony. The vernacular name in China is 川赤芍. This species is ½-1 m high, has a thick irregular taproot and thin side roots, and deeply incised leaves, with leaflets themselves divided in fine segments. It has two to four fully developed flowers per stem, that may be pink to magenta-red or rarely almost white. It is known from central China.
Borthwickia is genus of flowering plants, containing one species, Borthwickia trifoliata from Yunnan, China and Myanmar. The common name in Chinese is 节蒴木. It is a shrub or small tree with evergreen trifoliate leaves, whitish flowers clustered at the tip of the branches, with many stamens, and thin, knobbly, drooping fruits with many small red seeds.
Caltha dioneaefolia is a dwarf perennial herb, of the Buttercup Family (Ranunculaceae) with apparently seated pale yellow flowers with about seven stamens and two to three free carpels and leaves that are reminiscent of those of the Venus flytrap, but very small and with leaflike appendages on the leaf. It occurs in the southern Andes of Chile and Argentina, including on Tierra del Fuego and Hermite Island.
Caltha sagittata is a low to medium height, rhizomatomous perennial herb with ivory hermaphrodite flowers, belonging to the Buttercup family. It grows in clusters in sunny wet places in the Andes and related mountain chains. It has a disjunct distribution concentrated in the Southern Cone of South America.
Caltha novae-zelandiae, commonly known as New Zealand marsh marigold or yellow caltha, is a small, perennial herbaceous plant belonging to the family Ranunculaceae, that grows in open vegetations in mountainous areas, and is endemic to New Zealand.
Caltha obtusa; commonly known as white caltha; is a small, perennial herbaceous plant belonging to the family Ranunculaceae, that grows in open vegetations in mountainous areas, and is endemic to New Zealand's South Island.
Caltha introloba, commonly known as the alpine marsh-marigold is a small hairless, perennial alpine herb, that is endemic to the alpine regions of Australia and Tasmania.
Caltha scaposa is a low, perennial herb with one or two yellow hermaphrodite saucer-shaped flowers. This marsh-marigold species belongs to the buttercup family, grows in moist alpine fields and is native to the eastern Himalayas and the mountains on the eastern margin of the Tibetan highland.
Caladenia dorrienii, commonly known as the Cossack spider orchid is a species of orchid endemic to the south-west of Western Australia. It has a single hairy leaf and one, two or sometimes three small creamy-white flowers, usually with the lateral sepals and petals curving around the ovary and crossing each other. It is a rare orchid, only found in the extreme south-east of the state.
Hypericum cuisinii is a perennial herb in the genus Hypericum, in the section Adenosepalum. The herb has pale yellow flowers and occurs in Greece and Turkey.
Hypericum undulatum, the wavy St Johns Wort, is a herbaceous perennial flowering plant native to western Europe and northern Africa. The specific name undulatum is Latin, meaning "wavy" or "undulated", referring, just as the common name, to the wavy leaf margins of the herb. The plant has a diploid number of 16 or 32.
Mairia coriacea is a perennial plant assigned to the family Asteraceae. It has broad, tough and leathery, evergreen leaves. These have a narrowed foot and an entire margin or a few shallow, irregular teeth. They grow in a rosette directly from the rootstock. The plant produces flower heads with one whorl of white to mauve ray florets around many yellow disc florets, with one or few on top of a dark reddish, woolly stalk. Flower heads appear after the overhead vegetation burnt down, often destroying the leaves in the process. It can be found in the southern mountains of South Africa's Western Cape province. It is called leather leaves in English.
Mairia burchellii is a tufted perennial plant of up to 15 cm (6 in) assigned to the family Asteraceae. It has narrow leaves of up to 5 mm (0.20 in) wide, with single main vein and an entire margin. Flower heads only occur after a fire has destroyed the standing vegetation, mostly in November or between February and June. The flower heads sit individually or with a few on the tip of a purplish stalk, with a few narrow bracts, and consist of a row of pinkish ray florets around many yellow disc florets. It can be found in the southwest of the Western Cape province of South Africa.
Hypericum elodeoides, commonly called the Himalayan St. John's Wort, is a species of flowering plant of the St. John's wort family (Hypericaceae).
Taraxacum ceratophorum, also known as the horned dandelion, is a species of flowering plant within the genus Taraxacum and family Asteraceae. This alpine species has a preference for mountainous habitat, where it can be found growing at elevations up to 3000 meters above sea level. It is native to a large portion of the Northern Hemisphere, inhabiting various countries within Asia, Europe and North America.
