— The Merciera tenuifolia var. tenuifolia View in CoL (A5)

group.

Specimens from M. tenuifolia var. tenuifolia constitute this group. No single quantitative character ( Fig. 4 View Fig ) separates this group from the other violet-blue flowered groups (A3 and A4). However, the distinctly ascending leaves separate this group from all the other groups. Geographically, this group occurs in sympatry with the M. tenuifolia var. azurea group but does differ from it in having a more erect habit. According to ADAMSON (1954), M. azurea is only a smaller and stouter form of M. tenuifolia and he accordingly assigned it varietal status. The distance between the M. tenuifolia var. azurea and M. tenuifolia var. tenuifolia clusters revealed by CA and PCO do not support ADAMSON’ s concept of taxon boundaries.
