Abstract
Como parte de los estudios en curso sobre las Malvaceae de Túnez, se descubrieron poblaciones de dos especies de Hibiscus (H. rosa-sinensis y H. syriacus) y de Lagunaria patersonia en el norte de Túnez, que representan los primeros registros de la flora nacional y norteafricana. Se describen caracteres morfológicos, así como datos ecológicos y corológicos. Se proporcionan notas nomenclaturales sobre los nombres H. acerifolius (= H. syriacus), H. chinensis (= H. syriacus), H. patersonius (basiónimo de L. Patersonia) y H. rhombifolius (= H. syriacus), incluida la designación de holótipo para H. Chinensis (ilustración de van Braam Houckgeest), y designación de lectótipos para H. Acerifolius (una ilustración de Salisbury), H. Rhombifolius (ilustración de Cavanilles) y H. Patersonius (ilustración de Andrew). También se tratan otros nombres ilegítimos e inválidos (Althaea frutex, H. floridus, Ketmia syrorum, K. Arborea y K. Arborescens).
Highlights
Malvaceae Juss. is a family of about 243 genera and over 4225 species, mainly distributed in tropical areas, and occurring in temperate regions (Stevens, 2001–).Many Malvaceae species are used for various purposes, such as natural fibers, ornamentals, foods, vegetable oils [e.g. from baobab], beverages, timber, medicinals [e.g. for the demulcent nature, genus Althaea L., or astringent, or diuretic]
As part of an ongoing study on the family Malvaceae (e.g. Iamonico, 2010, 2014a, b, 2016, 2018; Iamonico & Peruzzi, 2014; Iamonico & Del Guacchio, 2017; Iamonico & Valdés, 2017) and the alien Flora of Tunisia (El Mokni & Iamonico 2017, 2018a, b, 2019; Iamonico & El Mokni, 2017, 2019a, b), field surveys allowed to find some populations of three Malvaceae species which were not previously reported from both the country and the whole of northern Africa [Hibiscus rosa-sinensis L., H. syriacus L., and Lagunaria patersonii (Andr.) G
The genus Hibiscus is represented in the flora of Tunisia by just one species, i.e. H. trionum L. (Le Floc’h et al, 2010: 268; Valdés, 2011a)
Summary
Malvaceae Juss. is a family of about 243 genera and over 4225 species, mainly distributed in tropical areas, and occurring in temperate regions (Stevens, 2001–).Many Malvaceae species are used for various purposes, such as natural fibers (e.g. cotton, genus Gossypium L.), ornamentals (e.g. genera Alcea L., Hibiscus L., Lavatera L.), foods (e.g. cacao, genus Theobroma L.), vegetable oils [e.g. from baobab (genus Adansonia L.)], beverages (e.g. colas, genus Cola Schott. & Endl.), timber (e.g. genus Tilia L.), medicinals [e.g. for the demulcent nature, genus Althaea L., or astringent (genus Hibiscus), or diuretic (genus Abutilon Mill.)] (see e.g. Mitchell, 1982; Forrest, 2006; Wakelyn et al, 2007; Benchasri, 2012; Ogbu, 2014; Ţîţei & Teleuță, 2018; Tumpa & Islam, 2019). As part of an ongoing study on the family Malvaceae (e.g. Iamonico, 2010, 2014a, b, 2016, 2018; Iamonico & Peruzzi, 2014; Iamonico & Del Guacchio, 2017; Iamonico & Valdés, 2017) and the alien Flora of Tunisia (El Mokni & Iamonico 2017, 2018a, b, 2019; Iamonico & El Mokni, 2017, 2019a, b), field surveys allowed to find some populations of three Malvaceae species which were not previously reported from both the country and the whole of northern Africa [Hibiscus rosa-sinensis L., H. syriacus L., and Lagunaria patersonii (Andr.) G. At the current state of knowledge, we tentatively consider Hibiscus rosa-sinensis as casual alien species for Tunisia and North Africa.
