These are a group of small-flowered annual or biennial species which share the characteristic of possessing only 3 coloured veins in each petal. Lavatera mauritanica would appear to have originated as a hybrid between Lavatera arborea and one of this group, perhaps Malva parviflora.

These species are generally of little horticultural merit, but the larger flowered forms of Malva linnaei are potential subjects for the garden, and Malva verticillata Crispa group is grown as an architectural and foliage plant as well as a salad vegetable.

This plant is more commonly met under the name of Lavatera cretica L. It has recently been reclassified as Malva linnaei on the basis of morphological and molecular data, the traditional placement, on the basis of the presence of fused bracteoles, not being representative of its true relationships. See the page on the Malva alliance for further discussion of the classification of true mallows and lavateras.

Detailed description with photo-illustrations.

Malva linnaei M.F. Ray is an erect hairy annual or biennial found in the Near East and Mediterranean region, including North Africa and the Canary Islands, and in Western Europe north to Brittany and Cornwall, growing to 2-4 feet in height. It is also found (naturalised?) in Madeira and the Azores, and is naturalised in a number of other regions. It bears small lilac flowers, in clusters in the leaf axils, in early summer. The flower size is variable, some populations bearing flowers of a size typical of the weedy mallows, and others bearing larger flowers comparable in size to smaller flowered forms of Malva sylvestris.

Detailed description with photo-illustrations (in preparation)

Malva nicaeensis is a annual, or less commonly biennial, species found in Macaronesia, the Mediterranean region, south west Asia including the western parts of Persia, Transcaucasia and southern Russia. It is also naturalised or casual in a number of regions, including California, Montana and New Jersey in the United States, Argentina, Chile, New Zealand, Tasmania, Victoria, Kangaroo Island in South Australia, and Swanland in Western Australia.

It grows from 1 to 5 feet high, with an erect central stem and spreading (often procumbent) side shoots. The leaves are orbicular to reniform (broader than long). The stems are glabrous, or bear a sparse covering of deflexed hairs. It bears small whitish flowers in clusters of 3 or 4 in the leaf axils.

Synonyms of Malva nicaeensis include  Althaea nicaeensis Alef., Malva arvensis C.Presl, Malva circinatta Viv., Malva excelsa C.Presl, Malva montana Grossh. and Malva setosa Cav..

Malva parviflora is an erect, sparsely hairy stemmed annual, bearing dense fasciculate clusters of small (½"-¾") pink or whitish flowers in the leaf axils. It is native to southern Europe, North Africa and south west Asia, extending as far as Turkestan and Afghanistan, and is naturalised in many other places, including all the Australian states, the Northern Territory and Lord Howe Ialand, most of South Africa, Lesotho, Nambia and Zimbabwe

N.Hallé.

Malva parviflora var. oxyloba

Malva parviflora var. oxyloba is a variety found in Palestine, Syria and Cyprus, differing from the type in the possession of very sharply serrate leaf margins, a non-accrescent calyx with narrower sepals, and a generally smaller and slenderer habit. Although markedly different in appearance from the type it is fully interfertile with it, and experimental genetic work indicates that the majority of the differences are under the control of a single dominant gene.

Synonyms of Malva parviflora var. oxyloba include  Malva oxyloba Boiss..

Other varieties of Malva parviflora have been recognised. Var. microcarpa (with smaller fruits) and var. cristata intergrade with the type, and are therefore not distinguishable entities. Var.arguta Post, from Lebanon, has acutely dentate leaf lobes. This might represent the heterozygous cross between var. oxyloba and the type.
