, Tenerife (Jardín de Aclimatación de la Orotava). The reason for including this species in a separate genus was the presence of nectaries in the base of each petal, which is unique in the Malveae tribe. Published studies (and some recent others not published yet) using molecular markers (chloroplast and ITS sequences) support this separation, as phylogenetic trees show L. phoenicea in a basal position in relation to the rest of Lavatera-Malva complex, and thus, as a palaeoendemic taxa.

This plant presents a clear bird pollination syndrome
Pollination syndrome
Pollination syndromes are suites of flower traits that have evolved in response to natural selection imposed by different pollen vectors, which can be abiotic or biotic, such as birds, bees, flies, and so forth. These traits include flower shape, size, colour, odour, reward type and amount, nectar...
