Calystegia (bindweed, false bindweed, or morning glory) is a genus of about 25 species of flowering plants in the bindweed family Convolvulaceae. The genus has a cosmopolitan distribution in temperate and subtropical regions, but with half of the species endemic to California. They are annual or herbaceous perennial twining vines growing 1–5 m tall, with spirally arranged leaves. The flowers are trumpet-shaped, 3–10 cm diameter, white or pink, with (in most species) a sometimes inflated basal epicalyx.
The genus bears much similarity to a related genus Convolvulus , and is sometimes combined with it; it is distinguished primarily by the pollen being smooth, and in the ovary being unilocular.
Some of the species, notably Calystegia sepium and C. silvatica , are problematic weeds, which can swamp other more valuable plants by climbing over them, but some are also deliberately grown for their attractive flowers.
Calystegia species are used as food plants by the larvae of some Lepidoptera species including Bedellia somnulentella (recorded on C. sepium) and small angle shades.
The name is derived from two Greek words kalyx or kalux, "cup", and stege, "a covering", meaning "a covering cup", [3] this refers to the large bracts that cover the sepals. [4]
The following species are recognised in the genus Calystegia: [5]
Convolvulaceae, known commonly as the bindweed or morning glory family, is a family of about 60 genera and more than 1,650 species of mostly herbaceous vines, but also trees, shrubs and herbs, and also including the sweet potato and a few other food tubers.
Morning glory is the common name for over 1,000 species of flowering plants in the family Convolvulaceae, whose current taxonomy and systematics are in flux. Morning glory species belong to many genera, some of which are:
Convolvulus is a genus of about 200 to 250 species of flowering plants in the bindweed family Convolvulaceae, with a cosmopolitan distribution. Common names include bindweed and morning glory; both names shared with other closely related genera.
Calystegia sepium is a species of bindweed, with a subcosmopolitan distribution throughout the temperate Northern and Southern hemispheres.
Convolvulus arvensis is a species of bindweed that is rhizomatous and is in the morning glory family (Convolvulaceae), native to Europe and Asia. It is a climbing or creeping herbaceous perennial plant growing to 0.5–2 m high. There are two varieties:
Bindweed may refer to:
Tetragonia tetragonoides, commonly called New Zealand spinach and other local names, is a flowering plant in the fig-marigold family (Aizoaceae). It is often cultivated as a leafy vegetable.
The morning glory Calystegia soldanella is a species of bindweed known by various common names such as sea bindweed, seashore false bindweed, shore bindweed, shore convolvulus and beach morning glory.
The morning glory Calystegia silvatica is known by the common name giant bindweed or large bindweed. It is the largest species of bindweed and is a strong rampant climber.
Calystegia macrostegia, with the common names island false bindweed and island morning glory, is a species of morning glory in the family Convolvulaceae.
Calystegia collina is a species of morning glory known by the common name Coast Range false bindweed. It is endemic to the Coast Ranges of northern and central California, where it grows on slopes and in woodlands, often on serpentine soils.
Calystegia malacophylla is a species of morning glory known by the common name Sierra false bindweed . It is endemic to California, where it grows in several of the mountain ranges, including the Central Coast Ranges and the Sierra Nevada.
Calystegia occidentalis is a species of morning glory known by the common name chaparral false bindweed.
Calystegia purpurata is a species of morning glory known by the common name Pacific false bindweed.
Calystegia stebbinsii is a rare species of morning glory known by the common name Stebbins' false bindweed. It is endemic to the Sierra Nevada foothills of California, where it is known from only two spots in El Dorado and Nevada Counties. It grows in unique habitat in chaparral on gabbro soils. It is a federally listed endangered species.
Calystegia subacaulis is a species of morning glory known by the common name hillside false bindweed.
Calystegia affinis is a critically endangered species of climbing or creeping vine in the plant family Convolvulaceae. It is endemic to Lord Howe Island and Norfolk Island. In 2003 only about 45 mature plants were known, with about 40 of those on Norfolk Island.
Convolvulus cantabrica, common name Cantabrican morning glory or dwarf morning glory, is a herbaceous perennial plant belonging to the genus Convolvulus of the family Convolvulaceae.
The morning glory Calystegia tuguriorum is a species of bindweed known as New Zealand bindweed, pōuwhiwhi, and pōwhiwhi. It is a perennial vine which grows in coastal and lowland areas throughout New Zealand, as well as being present in Chile and on the Juan Fernandez islands..
