- Abstract
Morphometric relationships between populations of Papaver radicatum within the southern Norwegian mountains were investigated using canonical variates analysis and Ward's clustering on capsule and leaf character sets. The survey describes patterns of variation among 13 wild-scored populations from five geographically disjunct localities, usually assigned to five races or subspecies. Our results from wild-collected material largely support earlier findings based on univariate statistics on cultivated material. In general, populations from within a disjunct locality (=subspecies) are most similar to other populations from the same locality. However, the subspecies vary in the degree to which they are differentiated in capsule morphology.... (More)
Morphometric relationships between populations of Papaver radicatum within the southern Norwegian mountains were investigated using canonical variates analysis and Ward's clustering on capsule and leaf character sets. The survey describes patterns of variation among 13 wild-scored populations from five geographically disjunct localities, usually assigned to five races or subspecies. Our results from wild-collected material largely support earlier findings based on univariate statistics on cultivated material. In general, populations from within a disjunct locality (=subspecies) are most similar to other populations from the same locality. However, the subspecies vary in the degree to which they are differentiated in capsule morphology. The subsp. groevudalense populations are morphologically close to the main group of subsp. ovatilobum populations. Subspp. intermedium and oeksendalense are clearly distinct from one another and from the other subspecies, whereas the single subsp. gjaerevolli population is more similar to the ovatilobum/groevudalense complex. Variation in leaf characters showed only partial congruence with variation in capsule characters. The pattern of morphological relationships among the subspecies is thus more complex than previously thought. The subspecies may have become differentiated during a period of isolation, but such results alone cannot indicate the duration of such a period.
