Geosiris aphylla

Geosiris aphylla is a species in the flowering plant family Iridaceae, first described in 1894. It is endemic to Madagascar. [1]

Contents

Geosiris aphylla is sometimes called the earth-iris. It is a small myco-heterotroph lacking chlorophyll and obtaining its nutrients from fungi in the soil. [2]

Description

Its rhizomes are slender and scaly, and stems are simple or branched. The leaves are alternate, but having no use, are reduced and scale-like (hence the epithet "aphylla," meaning "without leaves"). The flowers are light purple.

Range and habitat

Geosiris aphylla is native to central and eastern Madagascar. It lives in forest humus in humid lowland and montane forests, between 400 and 1200 meters elevation. [3]

<i>Iris</i> (plant) Genus of flowering plants in the family Iridaceae

Iris is a flowering plant genus of 310 accepted species with showy flowers. As well as being the scientific name, iris is also widely used as a common name for all Iris species, as well as some belonging to other closely related genera. A common name for some species is flags, while the plants of the subgenus Scorpiris are widely known as junos, particularly in horticulture. It is a popular garden flower.

<i>Bulbophyllum</i> Genus of orchids

Bulbophyllum is a genus of mostly epiphytic and lithophytic orchids in the family Orchidaceae. It is the largest genus in the orchid family and one of the largest genera of flowering plants with more than 2,000 species, exceeded in number only by Astragalus. These orchids are found in diverse habitats throughout most of the warmer parts of the world including Africa, southern Asia, Latin America, the West Indies, and various islands in the Indian and Pacific Oceans. Orchids in this genus have thread-like or fibrous roots that creep over the surface of trees or rocks or hang from branches. The stem is divided into a rhizome and a pseudobulb, a feature that distinguished this genus from Dendrobium. There is usually only a single leaf at the top of the pseudobulb and from one to many flowers are arranged along an unbranched flowering stem that arises from the base of the pseudobulb. Several attempts have been made to separate Bulbophyllum into smaller genera, but most have not been accepted by the World Checklist of Selected Plant Families.

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

Galax, the wandplant, wandflower, or beetleweed, is a genus in the flowering plant family Diapensiaceae, containing a single species, Galax urceolata. It is native to the southeastern United States from Massachusetts and New York south to northern Alabama, growing mainly in the Appalachian Mountains at altitudes of up to 1,500 m, where it grows in shaded places in forests. Galax urceolata can occur at multiple ploidy levels, an individual may be a diploid (2x), triploid (3x), or autotetraploid (4x) (autopolyploid). The cytotypes are neither morphologically nor geographically distinct, though there are slight climatic differences between the diploid and autotetraploid types. Outcrossing is likely to occur among cytotypes as well.

Seven are endemic to Madagascar, though one, C. roseus, is widely naturalized around the world. The eighth species, C. pusillus, is native to India and Sri Lanka. The name Catharanthus comes from the Greek for "pure flower".

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

Geosiris is a genus in the flowering plant family Iridaceae, first described in 1894. It was thought for many years to contain only one species, Geosiris aphylla, endemic to Madagascar. But then in 2010, a second species was described, Geosiris albiflora, from Mayotte Island in the Indian Ocean northwest of Madagascar. In 2017, a third species was found in Queensland, Australia, Geosiris australiensisB.Gray & Y.W.Low.

<i>Ravenala</i> Genus of trees

Ravenala is a genus of monocotyledonous flowering plants. Classically, the genus was considered to include a single species, Ravenala madagascariensis, commonly known as the traveller's tree, traveller's palm or East-West palm, from Madagascar. It is not a true palm but a member of the family Strelitziaceae. The genus is closely related to the southern African genus Strelitzia and the South American genus Phenakospermum. Some older classifications include these genera in the banana family (Musaceae). Although it is usually considered to be a single species, four different forms have been distinguished. Five other species were described in 2021, all from Madagascar: Ravenala agatheae Haev. & Razanats., R. blancii Haev., V.Jeannoda & A.Hladik, R. grandis Haev., Razanats, A.Hladik & P.Blanc, R. hladikorum Haev., Razanats., V.
