Joseph Marie Henry Alfred Perrier de la Bâthie was a French botanist who specialized in the plants of Madagascar.
Panicoideae is the second-largest subfamily of the grasses with over 3,500 species, mainly distributed in warm temperate and tropical regions. It comprises some important agricultural crops, including sugarcane, maize, sorghum, and switchgrass.
Perrierbambus is a genus of Madagascan bamboo in the grass family.
Aristida is a very nearly cosmopolitan genus of plants in the grass family. Aristida is distinguished by having three awns (bristles) on each lemma of each floret. The genus includes about 300 species found worldwide, often in arid warm regions. This genus is among those colloquially called three-awnswiregrasses, speargrasses and needlegrasses. The name Aristida is derived from the Latin "arista", meaning "awn".
René Paul Raymond Capuron was a French botanist. Capuron was responsible for an extensive amount of work on the tree flora of Madagascar. Several tree taxa with the specific epithet of capuronii honor his name, examples being Podocarpus capuronii and Schizolaena capuronii.
Isalo National Park is a National Park in the Ihorombe Region of Madagascar, in the southwestern corner of the Province of Fianarantsoa. The closest town is Ranohira, and the closest cities are Toliara and Ihosy. It is a sandstone landscape that has been dissected by wind and water erosion into rocky outcrops, plateaus, extensive plains and up to 200 m (660 ft) deep canyons. There are permanent rivers and streams as well as many seasonal watercourses. Elevation varies between 510 and 1,268 m.
Chasechloa is a grass genus in the tribe Paniceae, endemic to Madagascar. It was described by French botanist Aimée Antoinette Camus in 1948, who named it in honour of Mary Agnes Chase. Its two species were also classified in the genera Echinolaena and Panicum, but phylogenetic analysis confirmed that they form a distinct lineage.
Sartidia is a genus of Southern African and Madagascan plants in the grass family. It was split from Aristida in 1963 by South African botanist Bernard de Winter and contains six known species, of which Sartidia perrieri is considered extinct. Their natural habitats are warm, semi-arid savanna and dry forest at altitudes of 800–2,000 m (2,600–6,600 ft) where rainfall ranges from 250 to 1,500 mm per year. They are perennial grasses with inflorescence in a panicle.
Lecomtella is a genus of grasses with the sole species Lecomtella madagascariensis, native to Madagascar. It is the only genus in the tribe Lecomtelleae.
Neostapfiella is a genus of Madagascan plants in the grass family.
Alloteropsis semialata, known commonly as black seed grass, cockatoo grass, donkersaad gras, swartsaadgras, tweevingergras, and isi quinti, is a perennial grass distributed across much of tropical and subtropical Africa, Asia and Australia, as well as Papuasia and Madagascar. The genus name Allopteropsis comes from the Greek words "allotrios", meaning "belonging to another", and "opsis", meaning appearance. The specific epithet semialata comes from the Latin "semi" (half) and "ala" (wing), referring to the winged margins of the upper glume.
The flora of Madagascar consists of more than 12,000 species of plants, as well as a poorly known number of fungi and algae. Around 83% of Madagascar's vascular plants are found only on the island. These endemics include five plant families, 85% of the over 900 orchid species, around 200 species of palms, and such emblematic species as the traveller's tree, six species of baobab and the Madagascar periwinkle. The high degree of endemism is due to Madagascar's long isolation following its separation from the African and Indian landmasses in the Mesozoic, 150–160 and 84–91 million years ago, respectively. However, few plant lineages remain from the ancient Gondwanan flora; most extant plant groups immigrated via across-ocean dispersal well after continental break-up.
Oryza punctata is an annual grass in the rice genus Oryza, also known as red rice, related to cultivated rice O. sativa. O. punctata forms clumps or tussocks from 50–120 cm tall. It is a native to tropical Africa and Madagascar but is also found in Thailand and other parts of Indochina. O. punctata is a weed species in commercial rice growing operations although it appears to be rare in its native range. O. punctata has an IUCN status of least concern. It is not generally eaten or used as fodder by farmers but there is some evidence that it has been used as such during periods of famine. Due to the importance of the crop varieties of rice globally, the evolution of the Oryza genus as a whole has been studied extensively. A lot of information about O. punctata has been elucidated as a secondary benefit to this commercial research. O. punctata evolved some 5 million years ago in the second of two rapid radiation events that occurred in the Oryza L. genus.
Xyris jupicai, common name Richard's yelloweyed grass, is a New World species of flowering plants in the yellow-eyed-grass family. It is widespread in North America, South America, Mesoamerica, and the West Indies.
Iris perrieri is a plant species in the genus Iris; it is also in the subgenus Iris. It is a rhizomatous perennial, from the Savoy Alps in southern France and recently in Italy. It has green, deeply ribbed, sickle shaped leaves, a slender stem with a branch, 1–3 scented flowers that are violet or purple, with a white or pale blue beard. It is rarely cultivated as an ornamental plant in temperate regions, due to its rarity in the wild. It was once thought to be a form of Iris aphylla, before cell (chromosome) analysis determined it to be a separate species.
Aristida rufescens is a grass species native to Madagascar and to Mayotte in the Comoros archipelago. It was described by German agrostologist Ernst Gottlieb von Steudel in 1854.
Jumelleanthus is a monotypic genus of flowering plants belonging to the family Malvaceae. It only contains one species, Jumelleanthus perrieriHochr.
Aristida warburgii is a species of grass that is native to New South Wales and Queensland. It was first described by Carl Christian Mez in 1921 from a specimen collected near Maryborough, Queensland. The species epithet, warburgii, honours Otto Warburg.
