Abstract

Abstract:

Plastid atpB/rbcL intergenic spacer sequences were obtained from 21 selected taxa and

one hybrid of Anemoninae (Anemone, Pulsatilla, Hepatica) and compared with Ficaria (Ranun-

culinae) as an outgroup. From the resulting matrix (1226 bp) a single most parsimonious tree was

obtained (Fig. 1 ). The branching of this tree is confirmed by many informative indels and appears

largely congruent with past plastid restriction analyses. Several new taxa are added. The monophyly

of the Anemoninae and their early split into two major clades is supported: clade I with the chromo-

some base number x = 8, clade Ⅱ with the reduced x = 7. Clade Ⅰ is made up of the basal Pulsatilla

and the Rivularis + Vitifolia groups. The Multifida group links to the crown groups Coronaria,

Blanda and Nemorosa. Clade Ⅱ consists of the basal Dichotoma group, followed by Hepatica, and

finally by the N. Hemisphere Narcissiflora and the S. Hemisphere Antucensis groups as sisters. The

problems of the Anemoninae ancestry, phylogenetic differentiation, and recent attempts for systemat-

ic classification are critically discussed. In view of the still incomplete sampling of DNA data, a

conservative and informal approach to classification problems is recommended.
