Clematis occidentalis | |
Clematis occidentalis is a species of flowering plant in the buttercup family known by the common names western blue virginsbower or purple clematis. [1] It is native to much of southern Canada and the northern United States.
Clematis occidentalis has compound leaves with three leaflets. Its leaflets measure between 1.5 to 3.5 inches in length and up to 2 inches in width, featuring either a toothless edge or a few shallow teeth. The leaflets have sharply pointed tips and are attached to a hairy stalk. Their shapes can range from an egg or teardrop shape to a heart shape, and occasional irregular lobes in two or three parts. The surfaces of the leaflets are either hairless or sparsely hairy, sometimes transitioning to a hairless state. Clematis occidentalis lacks tendrils on its stems. The leaf stalks twine around surrounding vegetation and structures for support. The stems are predominantly round to squarish, generally hairless, and may display a purplish hue, with the lower stem becoming woody. [2]
Clematis occidentalis has single flowers that emerge from leaf axils, measuring 1.5 to 2.5 inches long. These blossoms feature four petal-like sepals, which range from blue-violet to pinkish-purple. The sepals are oblong-elliptic, hairy, and exhibit a drooping to somewhat spreading arrangement. The flower stalks are sparsely hairy, standing at 2 to 4 inches. Within the centre of the flower is a prominent column composed of numerous stamens surrounding a bundle of styles. Surrounding this central column, there are typically staminodia. The staminodia are flat, appearing white with noticeable veins that are often tinged pink. [2]
Clematis occidentalis produces plume-like fruit. The flowers transform into heads of finely hairy seeds, featuring elongated tail-like structures of about 2 inches in length. As the seeds ripen, they transition from green to rusty brown, while the tails become grey and feathery. The seeds are then dispersed by wind. [2]
There are three varieties:
Lathyrus japonicus, the sea pea, beach pea, circumpolar pea or sea vetchling, is a species of flowering plant in the legume family Fabaceae, native to temperate coastal areas of the Northern Hemisphere, and Argentina.
Lobelia siphilitica, the great blue lobelia, great lobelia, or blue cardinal flower, is a plant species within the family Campanulaceae. It is an herbaceous perennial dicot native to eastern and central Canada and United States. There are two recognized varieties of Lobelia siphilitica, var. siphilitica and var. ludoviciana. Blooming from August to October, it is short-lived, lasting only for a few years.
Acalypha rhomboidea is a plant in the spurge family, Euphorbiaceae.
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.
Clematis hirsutissima is a species of flowering plant in the buttercup family known by the common name hairy clematis or vase flower. It is a perennial herb that is native to much of the western United States, from Washington to Nebraska. It is a small, erect plant which, unlike other Clematis, does not generally produce vines. It is quite variable in appearance, especially across varieties. In general the hairy stem reaches up to about half a meter tall and has many large hairy leaves divided into lance-shaped lobes. The inflorescence appears at the tip of the stem and bears a solitary flower. The flower is made up of an urn-shaped cup of deep purple-blue petal like sepals, which are fuzzy and have pointed or rounded tips. Rare individuals have white or pinkish sepals. There are no true petals. The fruit is a hairy achene with a very long beak and a plume on the end; it is dispersed by wind.
Paeonia delavayi is a low woody shrub belonging to the peony family, and is endemic to China. The vernacular name in China is 滇牡丹. In English it is called Delavay's tree peony, Delavay peony, Dian peony, and dian mu dan. It mostly has reddish-brown to yellow, nodding flowers from mid May to mid June. The light green, delicate looking deciduous leaves consist of many segments, and are alternately arranged on new growth.
Pelargonium peltatum is a scrambling perennial plant with five shallow or deeply lobed, circular- to heart-shaped, somewhat fleshy leaves, sometimes with a differently coloured semicircular band, that has been assigned to the cranesbill family. It carries umbel-like inflorescences with 2–10, white to mauve, bilateral symmetrical flowers, each with a "spur" that is merged with the flower stalk. It is known by several common names including ivy-leaved pelargonium and cascading geranium. It is native to the Cape Provinces of South Africa. In its home range, it flowers year round but most vigorously from August to October.
Paeonia daurica is a perennial herbaceous plant belonging to the peony family. It has slender carrot-shaped roots, leaves mostly consisting of nine leaflets, with one flower per stem. The flower is subtended by none to two leafy bracts, and has two or three sepals, five to eight petals, and many stamens. The subspecies vary in the colour of the petals, the size and shape of the leaflets, and the hairiness of the leaflets and the carpels. Paeonia daurica can be found from the Balkans to Iran, and the Crimea to Lebanon, with the centre of its distribution in the Caucasus. It is also cultivated as an ornamental.
Enemion biternatum, commonly known as the false rue-anemone, is a spring ephemeral native to moist deciduous woodland in the eastern United States and extreme southern Ontario.
Stemodia durantifolia is a species of flowering plant in the plantain family commonly known as the whitewoolly twintip and purple stemodia. Stemodia durantifolia is native to the Americas, including Chile, Mexico, Texas, and the deserts of California and Arizona, and is often found in riparian habitats, preferring wet sand and rocks. It is a perennial herb producing a hairy, glandular, erect stem 10–100 cm (3.9–39.4 in) tall, with the toothed lance-shaped leaves found in pairs or triplets, attached to the stem with clasping bases. The inflorescence is a raceme of violet flowers, with each corolla held in a calyx of hairy, pointed sepals, and can often be found in bloom year-round. Although globally at low risk of extinction, Stemodia durantifolia is imperiled in California due to its rarity and threats from development.
Astragalus mollissimus is a perennial plant in the legume family (Fabaceae) found in the Colorado Plateau and Canyonlands region of the southwestern United States.
Paeonia corsica, also known as the Corsican peony, is a perennial herbaceous plant of 35–80 cm (14–31 in) high that belongs to the peonies. It naturally occurs on Corsica, Sardinia, on the Ionian islands and in western Greece. It has hairless green to purple stems, and the lower leaves consist mostly of nine leaflets with undersides which may carry felty hairs or are hairless. Its flowers have pink petals and purple filaments. Its vernacular name in Italian is peonia Corsa, and in French pivoine de Corse, both meaning "Corsican peony".
Paeonia algeriensis, also known as the Algerian peony, is a herbaceous species of peony that naturally occurs in the coastal mountain range of Algeria (Kabylie). It has solitary flowers with pink to magenta petals and one or two carpels per flower, that develop into follicles of about 5 cm long.
Agrimonia pubescens, the soft agrimony or downy agrimony, is a flowering plant in the genus Agrimonia, a member of the rose family. It grows in dry areas and woodlands.
Larsenianthus careyanus is a species of the ginger family (Zingiberaceae). It occurs in Bangladesh as well as northeast India. It is the type species of the genus Larsenianthus, which was newly established in 2010.
Otholobium dreweae is an upright shrublet assigned to the Pea family of about 15 cm (5.9 in) high, that appears after the vegetation burned down from the underground rootstock and forms mat-like clumps of hardly branching, leafy stems. The stems are set with stiff, entire, alternate leaves with a single leaflet and heads consisting of 12-18 initially dark pink, later white, pea-like flowers with a white nectar guide on a peduncle as long as the leaves at the end of the stem. This species is an endemic of the Kleinrivier Mountains in the Western Cape province of South Africa. It mostly flowers in November.
Otholobium lanceolatum is a small subshrub of up to 20 cm (7.9 in) high, that is assigned to the Pea family. It has up to 7 horizontal stems with raised tips, few hairless, alternately set leaves with only one leaflet and clusters of 15-27 white, pea-like flowers with a purple tip near the top of the short, seasonal shoots. It is endemic to one site near Caledon, South Africa. Flowers only appear in November and December within one year after a fire destroyed the vegetation.
Zanthoxylum dissitum is a woody plant native to China. It grows in upland thickets and open forests, forests, at 300-2600 m altitude.
