NUMBERS AND DISTRIBUTIONS OF VASCULAR BUNDLES IN SCAPES OF THREE ALLIANCES OF THE GENUS ALLIUM L. (LILIACEAE)

The arrangement and numbers of vascular bundles were documented for the species of the Allium cernuum Roth, Allium validum Wats., and Allium kunthii G. Don alliances. These characters proved consistent and diagnostically useful in the A. cernuum and A. validum alliances, but inconsistent in the A. kunthii alliance.
