The many-flowered grass-pink, Calopogon multiflorus, is a species of orchid. It is a perennial forb that requires recurring ground fires to maintain its habitat. It falls under the genus Calopogon , meaning "beautiful beard" in Greek, referring to the stamen-like bristles or beard on the lip. [1]

Distribution

Calopogon multiflorus is distributed throughout southeastern United States. It can be found mainly in Florida and also Alabama, Georgia, Mississippi, Louisiana, North Carolina, and South Carolina. This species has become endangered in Florida and North Carolina. [2]

Habitat and ecology

Calopogon multiflorus can be found in dry to moist flatwoods with wiregrass, longleaf pine, and saw palmetto. Its habitat also includes mesic pine savannahs on flat or gently-sloping terrain. These longleaf pine savannas were once widespread in southeastern North America, [3] and they burned naturally at least once a decade (see map in fire ecology). Large areas of suitable habitat have since been lost from logging and fire suppression.

The soil it grows in is usually sandy to loamy and acidic. Other species that are found growing nearby in the same habitat are blackjack oak ( Quercus marilandica ), little gallberry/ink berry ( Ilex glabra ), slender bluestem ( Schizachyrium tenerum ), little bluestem (S. scoparium), and savannah meadow beauty ( Rhexia alifanus ). [4] Over a wide range, this species typically does not occur on wet savannahs and bogs with pitcher plants, although one location in Louisiana does have some plants coexisting with pitcher plants. [4]

C. multiflorus requires prescribed annual winter fires for its appearance. In this way it is typical of many of the understory plants in pine savannas. [3] It is known to bloom six to eight weeks after a burn, likely benefiting from the lack of competition with other plants, and the nutrients released during a fire. [4]

Morphology

Morphology of Calopogon multiflorus

Characteristics of C. multiflorus are a dark purple rachis, a forked corm; pandurate lateral petals; elongated, acuminate floral bracts measuring (0.3–0.8)×(0.3–0.5) cm; and a pungent floral fragrance at peak anthesis. [5]

After sprouting in early spring, a single leaf, or sometimes two, appear clasping the bloom stem. The number of flowers can range from fifteen to just one flower on a stem. When the flower buds mature, they open in quick succession. Sometimes, it takes only two days for all of the flowers to open. They remain open for a couple days before withering and dropping to the ground. [1] The flowering season for C. multiflorus ranges from March to May. The average flowering season in Louisiana is mid-April. [4] This species requires full sun to light shade to grow ideally.

Pollination

This species falsely lures bees with the promise of pollen, but it is not fulfilled. The beard of the flower is deceptive in that once the insect lands on it, the lip of the beard swings down, hinge-like, placing the insect’s head and back on the column thereby picking up pollinium load, or placing the pollinium on the stigma if the insect already carries a load on its back. [1]

Conservation

Although this orchid is known historically in Florida and other managed areas, it is now rare due to fire suppression and conversion of habitat to pine plantations. [6] One way to protect this species is to burn flatwoods every 2–3 years during the growing season. These flatwoods can also be protected from bedding, draining, clearcutting, roller-chopping and other soil and hydrology disturbances. [6]

Longleaf pine Species of plant (tree)

The longleaf pine is a pine species native to the Southeastern United States, found along the coastal plain from East Texas to southern Maryland, extending into northern and central Florida. It reaches a height of 30–35 m (98–115 ft) and a diameter of 0.7 m (28 in). In the past, before extensive logging, they reportedly grew to 47 m (154 ft) with a diameter of 1.2 m (47 in). The tree is a cultural symbol of the Southern United States, being the official state tree of Alabama. Contrary to popular belief, this particular species of pine is not officially the state tree of North Carolina.

Flatwoods

Flatwoods, pineywoods, pine savannas and longleaf pine-wiregrass ecosystem are terms that refer to an ecological community in the Southeastern coastal plain of North America. Flatwoods are an ecosystem maintained by wildfire or prescribed fire and are dominated by longleaf pine, and slash pine in the tree canopy and saw palmetto, gallberry and other flammable evergreen shrubs in the understory, along with a high diversity of herb species. It was once one of the dominant ecosystem types of southeastern North America. Although grasses and pines are characteristic of this system, the precise composition changes from west to east, that is, from Texas to Florida. In Louisiana, savannas even differ between the east and west side of the Mississippi River. The key factor maintaining this habitat type is recurring fire. Without fire, the habitat is eventually invaded by other species of woody plants.

The Arboretum of the University of Central Florida is located on the main campus of the University of Central Florida in Orlando, Florida, United States. Covering 80 acres (320,000 m2), it contains more than 600 species of plants, including more than 100 bromeliads, in cultivated gardens.

<i>Calopogon</i> Genus of orchids

Calopogon, grass pink, is a genus of terrestrial orchids. The generic name is from Greek and means "beautiful beard", referring to the cluster of hairs adorning the labellum. The five species are native to the eastern United States, eastern Canada, Cuba and the Bahamas. The genus Calopogon is abbreviated Cpg in trade journals.

Wet meadow

A wet meadow is a type of wetland with soils that are saturated for part or all of the growing season. Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. Wet prairies and wet savannas are hydrologically similar. Wet meadows may occur because of restricted drainage or the receipt of large amounts of water from rain or melted snow. They may also occur in riparian zones and around the shores of large lakes.

<i>Platanthera ciliaris</i>

Platanthera ciliaris, commonly known as the yellow fringed orchid, yellow-fringed orchid, or orange-fringed orchid, is a large and showy species of orchid. It grows in "acid soil of hillside seepage bogs" in the longleaf pine landscapes of the Gulf Coast. Like many species in these habitats, including flatwoods, it is dependent upon recurring fire to create open conditions. Further north it is found in bogs, but even here it may be dependent upon fire to create open conditions.

Longleaf pine ecosystem

The longleaf pine ecosystem is a climax temperate coniferous forest habitat found within the southeastern United States; it includes many rare plant and animal species, and is one of the most biodiverse in North America. Once the largest ecosystem in North America, it now occupies less than a quarter of the original range. Degradation of the ecosystem is partially due to excessive timber harvesting, urbanization, and fire exclusion. Although the ecosystem is heavily fragmented at present, it still carries a great diversity of plant and animal species, many of which are endemic. A range of techniques, including planting longleaf seedlings, introducing prescribed burning regimens, managing native ground cover, and controlling invasive species within the ecosystem, are used in attempting to preserve this threatened ecosystem.

<i>Cleistesiopsis</i> Genus of orchids

Cleistesiopsis is an orchid genus in the tribe Pogonieae. Its members were included in Cleistes until 2009. Cleistesiopsis is native to the eastern and southeastern United States from New Jersey south to Florida, and west to Kentucky and Louisiana. The common names are rosebud orchid and small spreading pogonia.

Ruellia noctiflora, the nightflowering wild petunia, is a herbaceous perennial found along the Gulf coast. Both its specific and common names derive from its habit of nocturnal flowering. In spite of the common name it is in a different family from the garden petunia.
