Dendrosenecio cheranganiensis is one of the East African giant groundsel, this one endemic to the Cherangani Hills. Once it was a genus of Senecio but has recently been reclassified as a Dendrosenecio .
Dendrosenecio cheranganiensis can grow to 6 meters tall, with trunks up to 25 centimeters in diameter and pith with diameters of 2 centimeters. Leaf-rosettes of 40–70 leaves. Infrequent reproduction makes these giant plants sparsely branched and columnar. They rarely exceed three reproductive cycles. Leaves can be up to 94 centimeters long and 25 centimeters wide. Inflorescence can be 100 centimeters tall and 70 centimeters in diameter. 10 to 13 ray florets 10–13 and 25 to 50 disc florets. [2]
D. cheranganiensis grows between 2600 and 3400 meters on the slopes of the Cherangani Hills. [2]
The names for the giant groundsels have become somewhat confusing:
Dendrosenecio keniodendron or giant groundsel is a species of the genus Dendrosenecio of the large family Asteraceae and is one of the several species of giant groundsels endemic to the high altitudes of the Afrotropic, including Dendrosenecio johnstonii (Senecio battiscombei) occurring on Mount Kilimanjaro, Mount Kenya, and the Aberdare Mountains, Dendrosenecio keniensis occurring the lower alpine zone of Mount Kenya and D. keniodendron occurring in higher and drier sites on Mount Kenya. The giant rosette plants, sometimes 6 metres (20 ft) tall, often grow in even-sized stands, with different understory communities under different-aged stands.
Atop of Mount Kenya Senecio keniophytum is one of the endemic groundsel (Senecio) found at high altitudes in Kenya, such as the Afro-alpine zone of Mount Kenya, but not one of the giant Dendrosenecio that also live there.
Dendrosenecio battiscombei is one of the giant groundsels that lives on the slopes of Mount Kenya and the Aberdare Range. Like Dendrosenecio adnivalis on the Ruwenzori Mountains and the Virunga Mountains, Dendrosenecio battiscombei grows in the lower wetter areas of the Afro-Alpine zone.
Kleinia is a genus of African flowering plants in the sunflower family. Kleinia contains around 50 species and is distributed from the Canary Islands, throughout Tropical Africa to India and Arabia. It is closely related to the genus Senecio but is distinguished primarily by having succulent stems and/or leaves.
Dendrosenecio is a genus of flowering plants in the sunflower family. It is a segregate of Senecio, in which it formed the subgenus Dendrosenecio. Its members, the giant groundsels, are native to the higher altitude zones of ten mountain groups in equatorial East Africa, where they form a conspicuous element of the flora.
Senecio transmarinus is a sometimes straggling member of the flowering plants Asteraceae and species of the genus Senecio a perennial herb that grows on the higher elevations of the Rwenzori Mountains in Uganda. It is also found in Rwanda and the Democratic Republic of the Congo. The inflorescences consist of several flowerheads with large yellow ray florets.
Senecio maranguensis a 2-meter (6 foot) woody shrub or 6 meter (20 feet) climbing shrub from the family Asteraceae and species of the genus Senecio which makes its home at the same altitudes as the bamboo on the slopes of the mountains in East Africa.
Senecio mattirolii is a perennial herb of the family Asteraceae endemic to altitudes between 3600–4500 meters on the slopes of the mountains of the Ruwenzori Mountains in Uganda and the Democratic Republic of the Congo and an atypical species of the genus Senecio because it has purple flowers.
Dendrosenecio meruensis is one of the East African giant groundsel, this one is endemic to the slopes of Mount Meru. Once they were considered to be of the genus Senecio but since then have been reclassified into their own genus Dendrosenecio.
Dendrosenecio elgonensis is one of the giant groundsel of East Africa; this one is endemic to Mount Elgon. They used to be considered part of the genus Senecio but recently have been reclassified to their own genus, Dendrosenecio.
Dendrosenecio erici-rosenii one of the East African giant groundsel and this one can be found on the Rwenzori Mountains, Virunga Mountains and the Mitumba Mountains. It is a species of the genus Dendrosenecio and is also a collection of reclassified Senecio species.
Dendrosenecio kilimanjari is a giant groundsel found on Mount Kilimanjaro in Africa, below 4,000 metres (13,000 ft).
Dendrosenecio johnstonii, formerly Senecio johnstonii, is a species of giant groundsel found in the middle altitudes of Mount Kilimanjaro in Africa. A recent botanical reclassification split off some species formerly in Senecio, putting the giant groundsels in the new genus Dendrosenecio. It also redefined the former species Senecio cottonii, as a subspecies of Dendrosenecio johnstonii. Both genera are in the family Asteraceae. The giant grounsels of the genus Dendrosenecio evolved, about a million years ago, from a Senecio that established itself on Mount Kilimanjaro, with those that survived adapting into Dendrosenecio kilimanjari. As it moved down the mountain, the adaptations necessary for the new environment created the new species, Dendrosenecio johnstonii. Various subspecies are found on other mountains.
Dendrosenecio adnivalis is one of the giant groundsels of the mountains of Eastern Africa. D. adnivalis grows on the Rwenzori Mountains and on the Virunga Mountains in Uganda and the Democratic Republic of Congo.
Dendrosenecio brassiciformis is one of the East African giant groundsel, this one is endemic to the slopes of Aberdare Range and bearing fruit but once, and dying after. Once considered to be of the genus Senecio but since have been reclassified into their own genus Dendrosenecio.
Cineraria deltoidea is a perennial flowering plant of the family Asteraceae and the genus Cineraria which is also the closest known relative of the giant Dendrosenecio of East Africa.
Kleinia fulgens is a species from the genus Kleinia and the family Asteraceae which used to be of the genus Senecio.
Senecio madagascariensis, also known as Madagascar ragwort, is a species of the genus Senecio and family Asteraceae that is native to Southern Africa. Other common names include Madagascar groundsel and fireweed. It has been included on the noxious weeds list for Hawaii and the reject list for Australia. S.madagascariensis is the diploid cytotype of S.inaequidens.
Caputia medley-woodii is a species of flowering plant in the sunflower family, Asteraceae.
Senecio nevadensis is a species of flowering plant in the family Asteraceae.
