This a the list of the Eight species Crocosmia that are known to date:



Ambongensis:
Latin for 'From Ambong', a region in Mahajunga province, Madagascar, where the species was first found.
This is the only species of Crocosmia that is found naturaly occuring outside of the African Continent. It is in fact endemic to the Indian Ocean Island of Madagascar. Just two populations are known, both from areas of Limestone substrate in the Western part of the Island where the landscape is much eroded by water into steep slopes.
It was first collected by Henri Perrier de la Bathie in 1903.
Nothing is known about the biology  of the species apart from its peculiar habitat.



Aurea:
From the Latin Aureus, Golden, alluding to the deep Yellow colour of the flowers.
This plant is typically found on the forest floor and in forest margins, extending from Eastern Cape province, South Africa, to Uganda and Central African Republic.
The flowers are adapted for pollination by large Swallowtail Butterflies (Papilio), perhaps the only organisms that can feed on the nectar held within the slender perianth tubes.
It was first collected in Eastern South Africa by the early plant collector Johann Franz Drege, a Pharmacist by trade, in 1832.



Fucata:
From the Latin Fucatus, painted or stained, referring to the Scarlet to dark Red flowers with a Yellow throat and darker Red, sometimes Green, markings on the lower tepals.
This plant is restricted to the area of Namaqualand, the semiarid stretch of country lying along South Africa's  Western coast and near interior between the Olifants and Orange rivers, it has the narrowest range of any of Africa's Crocosmia species. It has been recorded on the slopes of Sneeukop (Snow Peak), second highest mountain in the Kamiesberg, and in the valley draining the range to the West on the farm Niekerksfontein.
It first came to botanical attention in 1838 when a painting of a plant in full bloom was published in Sydenham Edward's Botanical Register with a formal botanical description by William Herbert, the British bulbous-plant specialist, who named it Tritonia Fucata.
The German plant explorer Carl Ludwig-Zeyher must be credited with the first record of Crocosmia Fucata in the wild. He collected the plants in 1829 at 'Nieuw Kerksonteyn'.
It became known as Crocosmia in 1984.



Masoniorum:
Latin adjective from the English surname Mason (Masonius in Latin), the plural genitive being Masoniorum, thus named in honor of both Marianne Mason and her brother Edward, who made an important early collection of this species.
This rare plant is known from only a handful of localities, all in the mountains that lie to the North of the towns of Engcobo and Umtata in Transkei, the region of South Africa's Eastern Cape province that lies between the Kei River to the South and the KwaZulu-Natal border to the North.
These plants grow in rocky sandstone outcrops, often on cliffs, or on stream banks.
Some correspondence preserved at the Kew herbarium tells us that the species was first collected by Harry Bolus in January 1896.



Mathewsiana:
Latin epithet honouring the curator of the National Botanical Garden, Kirstenbosch-- Joseph William Mathews-- who worked closely with the botanist H. M. L. (Louisa) Bolus in growing many newly discovered species for illustration and additional study.
Locally common, Crocosmia Mathewsiana is a narrow endemic of Mpumalanga province, South Africa. It is restricted to the lower escarpment of the Northern Drakensberg between Graskop and Mariepskop, near Blyde River Canyon. The plants grow in light shade along the adges of Elfin forest, sometimes within the forest, or at the edges of taller evergreen forest. They grow in well drained sandy ground among boulders in the geological formation known as Black Reef Quartzite.
They are pollinated by large anthorphorine bees, particularly species of Amergilla (family Apidae).
Mathewsiana was evidently first collected in  February 1874 'in the vicinity of Lydenburg' in what was then the South African Republic, now Mpumalanga province, by one W. Roe, about whom there are no records.



Paniculata:
From the botanical term Panicle, a loosely and highly branched inflorescence(or cluster of flowers), derived from the Latin Panum, an ear of millet, which consists of a multibranched, almost brush-like cluster of flowers.
Native to Eastern Southern Africa, CrocosmiaPaniculata extends from the Northern Mpumalanga highlands near Blyde River Canyon and Graskop in South Africa in the North through Swaziland, interior Mpumalanga and Northeastern Free State into Lesotho and locally into the foothills  of KwaZulu-Natal Drakensberg.
Paniculata have a long perianth tube that is only accessible to long-billed sunbirds.
Mystery surrounds the first collection and type of Crocosmia Paniculata. It was discovered by the early KwaZulu-Natal collector, William Tyler Gerrard, who sent specimens to the Royal Botanic Gardens, Kew, in 1865.



Pearsii:  
Named for Reginald Oliver Pearse, who was responsible for drawing attention to this neglected species, which until the publication of his book, Mountain Splendour, was confused with Crocosmia Paniculata.
Originally known from a few inaccessible sites in the high Drakensberg of Southern Africa, near Cathederal Peak in KwaZulu-Natal province, South Africa, records now show the CrocosmiaPearsii extends to the North as far as Basuto Gate, North of The Sentinel in Free State province, and almost certainly also grows in adjacent Eastern Lesotho.
Most plants grow in basalt outcrops and cliffs, mostly on cooler slopes at elevations above 7000 feet. It loves icy cold winters and cool summers.
This plant was first introduced into cultivation in Great Britain in 1991 by James Compton, John D'Arcy and Martyn Rix.



Pottsii:
Named in honour of George Honington Potts of Fettes Mount, Lasswade, Scotland, who evidently first grew Crocosmia Pottsii and provided plants that were grown at the Royal Botanic Garden, Edinburgh, and at Baden-Baden, Germany, in the garden of horticulturist Max Leichtlin, who then distributed it widely.
The range of Crocosmia Pottsii is restricted to Eastern South Africa and extends from near Umtata in Eastern Cape province through KwaZulu-Natal as far North as Melmoth in Zululand. It is a streamside plant and may be found growing in light bush along the banks of rivers and small streams at elevations of 1000 - 4000 feet.
