Acalypha gracilens is a species of flowering plant in the family Euphorbiaceae. Common names include slender threeseed mercury; three-seeded mercury; shortstalk copperleaf; slender copperleaf. It is native to the south-eastern United States.
Annual. Plant is erect with pubescent stems coming from the taproots. The leaves are alternate with two lateral veins beginning from the base, prominent and parallel to the midrib, crenate to crenate-serrate, or petiolate. The spikes are axillary or terminal, or both. The bracts are leaf-like. There are no petals. The flowers are pistillate with 3–5 sepals and a 3-locular ovary. The staminate flowers with 4 sepals and 8–16 stamens. The capsules are broader than they are long. [1]
The plant grows up to 0.8m high. The stems are freely branched and densely pubescent with short incurved (or appressed) ascending trichomes. The leaves are elliptic to elliptic-lanceolate which are 2–6 cm long and 0.5–2 cm wide, obtuse, crenate. The base of the leaves are cuneate to rounded, with pubescence of both surfaces (more or less glabrate). The petioles of principle leaves are 0.4–1.5 cm long. The axillary spike has 1–5 pistillate flowers near the base that are interrupted and continued with a spike of staminate flowers. The pistillate bracts are often stipitate-glandular, teeth triangular, 5–13. The seeds are reddish to black in color and are ovoid, 1.2–1.8mm long. Flowers in June and into late frost. [1]
A. gracilens is found throughout the south-eastern U.S. coastal plain and piedmont, eastern Midwest, and New England. [1]
In the south-eastern U.S. coastal plain it is a common plant found on frequently burned sandhills (Entisols), and in pine flatwoods (Spodosols) and upland pine communities (Ultisols), as well as floodplain forest (Alphisols). [1] [2] It thrives in frequently burned pine communities. [3] It occurs in both native communities and areas with very disturbed soil. It occurs in a fairly wide range of well-drained soils, from deep sand to loams. Its light tolerance is fairly broad, from full light to shaded areas on the margins of clearings. [4] In addition to the coastal plain it is common throughout the Piedmont region and infrequent in the mountains. [1]
Associated species include Liatris gracilis, L. tenuifolia, Polygonella gracilis, Didodia teres, Chrysopis lanuginosa, Rubus cuneifolis, Hypericum gentianoides, Trichostema dichotomum, Eupatorium compositifolium , and others. [4]
Flowers spring to fall through most of its range. Flowers all year in southern Florida. [2]
This species is believed to disperse by explosion mechanisms or by ants. [5]
Acalypha is a genus of flowering plants in the family Euphorbiaceae. It is the sole genus of the subtribe Acalyphinae. It is one of the largest euphorb genera, with approximately 450 to 462 species. The genus name Acalypha is from the Ancient Greek ἀκαλύφη (akalúphē) ("nettle"), an alternative form of ἀκαλήφη (akalḗphē), and was inspired by the nettle-like leaves. General common names include copperleaf and three-seeded mercury. Native North American species are generally inconspicuous most of the year until the fall when their stems and foliage turn a distinctive coppery-red.
Amaranthus wrightii is a species of flowering plant. It goes by the common name of Wright's amaranth. It occurs from western Texas into southern Arizona and as far north as Colorado at elevations between 500–2,000 m (1,600–6,600 ft).
Acanthophoenix is a genus of flowering plants in the palm family from the Mascarene Islands in the Indian Ocean, where they are commonly called palmiste rouge. A genus long in flux, three species are currently recognized, though unsustainable levels of harvesting for their edible palm hearts have brought them all to near extinction in habitat. They are closely related to the Tectiphiala and Deckenia genera, differing in the shape of the staminate flower. The name combines the Greek words for "thorn" and "date palm".
The flowering shrub Acalypha californica is known as the California copperleaf, and sometimes by the older name Pringle three-seeded mercury. It is the only Acalypha species native to California, where it is most abundant in the hills of San Diego County. It is a member of the chaparral plant community.
Acalypha rhomboidea is a plant in the spurge family, Euphorbiaceae.
Allagoptera caudescens is a species of flowering plant in the palm family endemic to Brazil, where it is known as buri palm. The older name Polyandrococos combines the Greek words for "many" and "anther" with the name of another palm genus Cocos, and the epithet is Latin for "bearlike", referring to the hairy tomentum. It was formerly classified as Polyandrococos caudescens, the only species in the genus Polyandrococos.
Sclerosperma is a monoecious genus of flowering plant in the palm family found in Africa where three species are known. Having no obvious relatives, it does resemble the Madagascar native Marojejya though a detailed study of Madagascar's palms is required to determine if any true relationship exists. The lack of relatives, and its interesting qualities, indicate, at one time, the existence of a diverse African palm flora. The name is from two Greek words meaning "hard" and "seed".
Synechanthus is a monoecious genus of flowering plant in the palm family found in Mexico, Central and South America. Commonly called bola, palmilla, or jelly bean palm, they are closely related to members of Chamaedorea, only distinguished by their flower and fruit form. The Greek genus name is a combination of "united" and "flower".
Cypripedium parviflorum, commonly known as yellow lady's slipper or moccasin flower, is a lady's slipper orchid native to North America. It is widespread, ranging from Alaska south to Arizona and Georgia. It grows in fens, wetlands, shorelines, and damp woodlands.
Acalypha indica is an herbaceous annual that has catkin-like inflorescences with cup-shaped involucres surrounding the minute flowers. It is mainly known for its root being attractive to domestic cats, and for its various medicinal uses. It occurs throughout the Tropics.
Acalypha australis, commonly known as Asian copperleaf, is a species of flowering plant in the family Euphorbiaceae native to eastern Asia.
Acalypha ostryifolia, sometimes spelled ostryaefolia, is a plant in the family Euphorbiaceae and is commonly known as hophornbeam copperleaf, hornbeam copperleaf, or pineland threeseed mercury, is an annual herb of the copperleaf genus Acalypha. It is a native of North and Central America and is generally considered a weed.
Carex eburnea, known as ivory sedge, ebony sedge, and bristleleaf or bristle-leaved sedge, is a small and slender sedge native to North America, from Alaska and Newfoundland south to central Mexico.
Acalypha virginica, commonly called Virginia threeseed mercury or Virginia copperleaf, is a plant in the spurge family (Euphorbiaceae). It is native to the eastern United States. It is found in a variety of natural habitats, particularly in open woodlands and along riverbanks. It is a somewhat weedy species that responds positively to ecological disturbance, and can be found in degraded habitats such as agricultural fields.
Fatoua villosa is an annual herb in the Moraceae (mulberry) family. Common names include mulberry weed, crabweed, or hairy crabweed in English,kuwakusa in Japanese, and shuǐ shémá (水蛇麻) or xiǎo shémá (小蛇麻) in Mandarin. It is native to Eastern Asia, some Pacific islands, and parts of Australia, including in two Australian states, the Bismarck Archipelago, China, Indonesia, Japan, Korea, New Guinea, the Philippines, the Solomon Islands, Taiwan, Thailand and Vietnam. It has become an invasive species in the United States where it grows in disturbed areas such as flowerbeds, greenhouses, and agricultural fields.
Hypericum tenuifolium, known as Atlantic St. John's-wort and sandhill St. John's-wort, is a species of flowering plant in the St. John's wort family, Hypericaceae. It is native to the Southeastern United States.
Scaevola repens is a shrub in the family Goodeniaceae, endemic to the south west of Western Australia.
Aporosa octandra is a species of plant in the family Phyllanthaceae found from Queensland and New Guinea to Indonesia, Zhōngguó/China and India. It is a highly variable plant with 4 named varieties.
