Claytonia saxosa

Claytonia saxosa, known by the common name Brandegee's springbeauty, is a species of wildflower in the family Montiaceae.

Contents

Distribution

The wildflower is endemic to northern California and southern Oregon. In northern California it is located on serpentine soils. In Oregon it is located in three places on basalt soils in the Cascade-Siskiyou National Monument in southern Oregon. It is found on rocky open slopes at mid to high elevations.

Description

Claytonia saxosa is a small, compact annual herb forming clumps a few centimeters wide in rock crevices. Serpentinite is the favored geologic substrate of this species. The leaves are small, with fleshy spatulate blades. The basal leaves and flowering stems are pink or red in color, packed densely together about the short stem that surmounts a minute, tuberous caudex. The chromosome number of the species is 2n = 16. [2]

Two to ten flowers emerge from the clump, each with five light pink petals under a centimeter long. The bloom period is March to May.

It is a perennial herb growing from a long, budding rhizome and producing an erect stem up to 40 centimeters tall. The basal leaves have oval blades up to 9 centimeters long with heart-shaped bases where they attach to their long petioles. There is also a pair of oval-shaped leaves at a midpoint on the stem. The stalked inflorescence bears up to 12 small flowers with five white petals each about a centimeter long.

<i>Claytonia rubra</i> Species of flowering plant

Claytonia rubra is a species of wildflower in the family Montiaceae known by the common names redstem springbeauty and erubescent miner's lettuce. It is native to western North America from southwestern Canada to the United States of America extending from The Black Hills and western slopes of the Rocky Mountains to the Cascade and Coast Range, Ochoco and Wallowa Mountains south to the Warner Mountains, Yolla Bolly Mountains, and Sierra Nevada and Transverse Ranges [Mt. Pinos and Mt. San Gorgonio], where it is found in coniferous forests and shrublands. This is an annual herb with stems up to about 15 centimeters long. Some individuals may overwinter as biennials. The basal leaves have small rounded to diamond-shaped blades on long, tapering petioles. There are also leaves on the stem which may be rounded or squared and sometimes fuse together to create a bowl around the stem. All the leaves possess blunt (obtuse) tips according to published descriptions and taxonomic treatments. The herbage is red or pink in color at all stages of development. The inflorescence is a dense cluster of up to 30 tiny flowers, each with petals less than 4 millimeters long and white to pink-tinted in color. Together with Claytonia perfoliata and Claytonia parviflora, Claytonia rubra comprises what is almost certainly a polyploid pillar complex based on three diploid species, each occupying a definitive ecological niche

Claytonia umbellata is a species of wildflower in the purslane family known by the common name Great Basin springbeauty. It is native to the Great Basin of the United States, where it grows mainly in subalpine coniferous forests, often on north-facing exposed slopes in the talus. It is a perennial herb growing from a tuberous root up to 5 centimeters wide and a thin taproot. Most of the stem develops underground, as do the petioles of the most basal leaves. Above the ground appear a few oval-shaped fleshy red to green leaves and an inflorescence of up to 12 flowers. Each flower has five magenta to deeply pink-tinted white petals.

<i>Claytonia caroliniana</i> Species of flowering plant

Claytonia caroliniana, the Carolina springbeauty, is an herbaceous perennial in the family Montiaceae. It was formerly placed in the Portulacaceae. Its native range is eastern and central North America. It is most commonly found in the New England area of the United States but its habitat extends from Ontario and a northern limit in the Cape Anguille Mountains of Newfoundland and south to Alabama. It grows approximately 6 inches tall in forests of the Appalachian Mountains and piedmont

Claytonia tuberosa, commonly known as Beringian springbeauty or tuberous springbeauty, is a species of flowering plant in the family Montiaceae. It is a perennial herb indigenous to Alaska, British Columbia, Northwest Territories, and the Yukon of North America, westward to East Asia–Siberia. The perennial grows from a globose tuberous root to a height of 15 centimetres (6 in) and bears several hermaphrodite white flowers on stems bearing a single pair of petiolate cauline leaves. Its closest relative is probably Claytonia virginica.

<i>Claytonia rosea</i> Species of flowering plant

Claytonia rosea, commonly called Rocky Mountain spring beauty, western springbeauty or Madrean springbeauty, is a diminutive spring blooming ephemeral plant with pale pink to magenta flowers.
