Ruspolia is a genus of flowering plants belonging to the family Acanthaceae. [1]
Description
A genus of shrubby herbs or shrubs. [2] [3] [4] The leaves are arranged opposite, [3] [5] they have visible linear cystoliths. [2] The flowers are in spikes or panicles, [3] or in 3-7-flowered, [5] cymules aggregated into long raceme-like cymes. [2] The flower has bracts and bracteoles (small bracts) that are narrow and inconspicuous. [3] The flower calyx is deeply 5-lobed, [2] [3] [4] with narrow, [3] or linear-lanceolate or filiform (thread-like) shaped lobes. [2] Sometimes with thread-like tips. [3] The corolla-tube is narrowly cylindrical, [3] and long and linear. [2] [4] it is divided into 5 subequal lobes, [3] which are spreading or reflexed. [2] The corolla (petals of the flower) are usually red, but may be salmon-pink, scarlet or orange-red. They are also hairy and sometimes glandular, on the outside. [2] It has 2 stamens which are just exserted (projected beyond the corolla-tube). [2] [3] They have anthers which are 1-celled. The ovary is 2-celled with 2 ovules in each cell or loculus. [2] [3] Meaning it has 2-4-seeds. It has a filiform (thread-like) shaped style. [3] The fruit or seed capsule is club-shaped, [3] with solid stalk-like basal part. [2] Inside the capsule, the seeds are smooth and glabrous or variously ornamented. [3] They are situated on prominent hook-shaped retinaculas (thick fibres), without hygroscopic hairs. [2]
It has a chromosome count of 2n=21 [6]
Distribution and habitat
Its native range is Tropical Africa, southern Africa and Madagascar. It is found in Angola, Botswana, [2] Cameroon, Central African Republic, Chad, Ethiopia, Ghana, Guinea, Guinea-Bissau, Kenya, Malawi, Mali, Mozambique, Nigeria, Senegal, Sierra Leone, Somalia, South Africa (in KwaZulu-Natal and the Northern Provinces) Sudan, Tanzania, Togo, Uganda, Zambia, Zaïre and Zimbabwe. [1]
Habitat
Lowland and medium elevation woodland, bushland and dry forests. [7]
Taxonomy
The genus name of Ruspolia is in honour of Eugenio Ruspoli (1866–1893), an Italian explorer and naturalist. [8] It was first described and published in H.G.A.Engler & K.A.E.Prantl, Nat. Pflanzenfam. Vol.4 (Issue 3b) on page 354 in 1895. [1] The genus was recognized on 23 January 2009, by the United States Department of Agriculture and the Agricultural Research Service, but they do not list any known species. [9]
Known species
According to Kew: [1]
- Ruspolia australis (Milne-Redh.) Vollesen
- Ruspolia decurrens (Hochst. ex Nees) Milne-Redh.
- Ruspolia hypocrateriformis (Vahl) Milne-Redh.
- Ruspolia seticalyx (C.B.Clarke) Milne-Redh.
GRIN accepts just Ruspolia hypocrateriformis (Vahl) Milne-Redh. and Ruspolia seticalyx (C. B. Clarke) Milne-Redh.. [9] Other sources claim that there are up to 6 species [6] Flora of Zimbabwe notes 5 species in Africa and Madagascar, (3 within Zimbabwe: Ruspolia australis, Ruspolia decurrens and Ruspolia seticalyx). [10]
Ruspolia hypocrateriformis (or 'Red Ruspolia'), is used as a garden shrub in South Africa and Namibia. [11]
