The typification of five names in tribe Antirrhineae (Plantaginaceae): Antirrhinum crassifolium (≡ Chaenorhinum crassifolium), var. parviflorum, C. flexuosum hispanicum subsp. cadevallii), formenterae, and Linaria serpyllifolia serpyllifolium) is discussed. are lectotypified using specimens from MA, LAU, COI, LY, C, respectively.

the biogeography of genus linaria was revealed by the available chromosome counts from all over the world. chromosome numbers of 92 taxa of the genus linaria are included in an on-line karyological database. furthermore, information about chromosome numbers taken from 374 literature sources was used in this paper. each database record includes name of taxon, data on chromosome and data on the o...

species but it took a defect in only a single gene to convert the plump flowers of the toadflax, Linaria vulgaris (main picture, on the left), into the spikes of Peloria, on the right. Peloria (Greek for 'monster') was named by Linnaeus 250 years ago, when he realized it must have arisen from the normal toadflax.
