Delphinium treleasei

Delphinium treleasei, commonly known as named glade larkspur or Trelease's larkspur, is a perennial flowering plant found it temperate areas of the eastern United States. [2] It is native to Missouri and Arkansas [2] where it is often situated in limestone glades but is not common in North America. It is endemic to Ozark highlands in eight southwestern Missouri counties and eight counties in northwestern Arkansas. D. treleasei is a vascular, seed plant, part of the buttercup family (Ranunculaceae). [3] The name Delphinium treleasei originates from the Greek "delphis" which means dolphin in reference to the flower shape of many buttercups and the specific epithet "treleasei" honors William Trelease who was director of the Missouri Botanical Garden from 1889 to 1912.

Description

Delphinium treleasei grows 2–3 ft (0.61–0.91 m) tall and has loose, terminal racemes of blue to blush-purple flowers. These bloom in spring, usually May to June. Flowers are 1 in (25 mm) long, comples, asymmetrical and have five sepals, one is spurred in to a prong that coined the common name, Larkspur. Inflorescences have 5-30 flowers. Deep green leaves are narrowly and deeply divided, pedate in shape, and mostly basal. All parts of this plant are poisonous if ingested. [4] [5]

Habitat

Delphinium treleasei natural habitat is open juniper glades on calcareous substrate. [6]

Conservation

Delphinium treleasei is locally abundant but is endemic and limited by microhabitat in its distribution range. It is vulnerable to habitat destruction. There are no current actions for conservation and D. treleasei is unlisted. [1]

<i>Delphinium</i> Genus of flowering plants

Delphinium is a genus of about 300 species of annual and perennial flowering plants in the family Ranunculaceae, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa. The genus was erected by Carl Linnaeus.

<i>Consolida</i> Genus of flowering plants

Consolida is a genus of about 40 species of annual flowering plants in the family Ranunculaceae, native to western Europe, the Mediterranean and Asia. Phylogenetic studies show that Consolida is actually an annual clade nested within the genus Delphinium and it has been treated as a synonym of Delphinium in Kew's Plants of the World Online. The name of the genus comes from an archaic use of consolidation, meaning "healing", in reference to the plant's medieval use for healing wounds.

<i>Delphinium bakeri</i> Species of flowering plant

Delphinium bakeri, or Baker's larkspur, is a species of perennial herb in the buttercup family, Ranunculaceae. It is endemic to California in the United States, where it is a federally listed endangered species. It is known in the wild from one remaining occurrence near Salmon Creek in Sonoma County, where only seven plants remained as of March 2006.

<i>Delphinium luteum</i> Species of flowering plant

<span class="mw-page-title-main">Hercules Glades Wilderness</span> Wilderness area in Missouri

The Hercules Glades Wilderness is a 12,314-acre (50 km2) wilderness area in Taney County in the Ozarks of southwest Missouri. The United States Congress designated it a wilderness in 1976, making it the oldest wilderness area in Missouri. It is one of eight wilderness areas in the Mark Twain National Forest and is within the Ava-Cassville-Willow Springs ranger district, about 10 miles (16 km) northeast of Branson, Missouri. Hercules Glades Wilderness derives its name from the open limestone glades (balds) that dot its landscape. The high points of Coy Bald and Pilot Knob stand 600 feet above Long Creek and offer splendid views of the drainage. Near the middle of the wilderness area is the main set of waterfalls, though Long Creek has several other smaller waterfalls and cascades along its path.

<span class="mw-page-title-main">Calcareous glade</span> Type of ecological community found where bedrock occurs near the surface.

A calcareous glade is a type of ecological community that is found in the central Eastern United States. Calcareous glades occur where bedrock such as limestone occurs near or at the surface, and have very shallow and little soil development. Due to the shallow soil and the extreme conditions created by it, trees are often unable to grow in the glades. This creates a habitat that is usually sunny, dry, and hot. Calcareous glade vegetation is more similar to that of a desert habitat than a grassland, being dominated by small spring annuals with occasional geophytic or succulent perennials.

<i>Delphinium grandiflorum</i> Species of flowering plant

Delphinium grandiflorum is a species of Delphinium known by the common names Siberian larkspur and Chinese Delphinium. It is native to Russia and China. There are several popular cultivars in several colours which are grown as ornamental plants, including 'Blue Butterfly', 'Summer Morning', 'Blue Mirror', and 'Summer Stars'. Like many other larkspurs, this plant is poisonous. It is much shorter and more compact than the more familiar tall D. elatum, with dispersed flowers, rather than single spikes.

Delphinium umbraculorum is a species of larkspur known by the common name umbrella larkspur. However, its epithet does not denote an umbrella. Instead, it describes the habitat of this plant, usually shady and cool places. It is often confused with D. parryii which has similar flowers and D. patens which has similar stems and leaves. It is endemic to California, where it grows in the woodlands of the coastal mountain ranges from Monterey to Ventura Counties. It is a perennial herb producing an erect stem 40 to about 80 centimeters tall. The hairless leaves are located at the base of the plant and along the stem as well. The inflorescence bears several flowers with reflexed dark blue sepals and a spur over a centimeter long. The fruit is between 1 and 2 centimeters long.

<i>Delphinium geyeri</i> Species of flowering plant

Delphinium geyeri is a species of plant in the Ranunculaceae family that is often called by the common names plains larkspur and foothills larkspur. It is infamous for causing the deaths of cattle grazing in the spring because it is especially poisonous before it flowers and so it is also called poisonweed by ranchers. It is a medium to tall plant that has very striking blue flowers and is occasionally grown in native plant gardens for this reason. It grows mainly in Wyoming with large population in northern Colorado, northeastern Utah, and parts of Nebraska.

<i>Delphinium glareosum</i> Species of larkspur

Delphinium glareosum is a species of larkspur which grows in Oregon, Washington, and British Columbia. It is in the Ranunculaceae. These plants favor rocky slopes. They flower in summer. Like all members of the genus Delphinium, rockslide larkspur is poisonous.
