The Morphological Variation and Geographical Distribution of Biscutella glacialis (Boiss. etReuter) Jordan in Spain
1986): The morphological variation and geographical Biscutella glacialis (Boiss. et Reuter) Jordan in Spain. ? Folia Geobot. Phytotax., Praha, 21: 397 ? 403. ? A study was made of the morphological variation in seven population samples of B. glacialis. Data on quantitative and qualitative characters reveal that one of the populations differs considerably from the rest. Observations on geographical distribution show that this species is not endemic to the peaks of Sierra Nevada but far more widely distributed than previ? ously realized. Two varieties of B. glacialis, one of which is new, are described.
