5b. Myosotis alpestris subsp. asiatica var. albicans (H. Riedl) Y. Nasir, comb. et stat. nov.

YASIN J. NASIR

  • Myosotis albicans Riedl

    Fl. Per.: July-August.

    Distribution: Pakistan, Kashmir.

    Myosotis albicans was said to differ from Myosotis alpestris in the lighter coloured flowers (white or pale blue), and according to Kazmi (l.c., in notes to Myosotis alpestris ssp. Asiatica) a calyx which is broadly rounded at the base and nutlets that are not keeled ventrally and are broad margined towards apex. The specimens with light coloured flowers and provisionally placed under var. albicans as they do not entirely relate to Myosotis alpestris subsp. asiatica. In the specimens examined of both taxa, except for flower colour, the other characters employed to differentiate the two are not clear-cut and overlap. For instance R.R. & I.D. Stewart 17851 and 17647, both with pale or white flowers have nutlets which are ± keeled ventrally such as found in Myosotis alpestris. The calyx in both specimens are not exactly rounded at base, but somewhat tapering towards the pedicels. It appears that other taxa as Myosotis sylvatica and Myosotis arvensis may also be involved. For instance J. Lamond 1806 except for white flowers agrees in leaf shape and unbranched habit to Myosotis sylvatica. R.R. Stewart & A. Rahman 29964 from Swat agrees in habit with Myosotis sylvatica but the flowers are mentioned in note as ‘some white’.

    The group comprising Myosotis alpestris, Myosotis Sylvatica & Myosotis arvensis and possibly others, possiably form a close-knit group in which transitional forms occur. Much more field work and collection involving hybridization and population study is required to get a clear-cut picture of the group in the Himalaya.
