Viburnum rufidulum has been considered in the past to be a variety of V. prunifolium L. Also, at one time V. cassinaides L was thought of as a variety of V. nudum L. In addition to these species, V. Opulus var. americanum (Mill) Ait. and V. Lentago L. were studied. The vascular structure was determined primarily by microscopic examination of stained serial sections cut in a transverse plane. The flowers used were either collected from living plants and preserved directly in 70% Ethyl alcohol or were taken from herbarium sheets of the Massachusetts College of Pharmacy and treated with dilute potassium hydroxide solution before embedding in paraffin. 2013-04-09T18:32:13Z 2013-04-09T18:32:13Z 1942 1942 Thesis/Dissertation b14787131 https://hdl.handle.net/2144/5384 en_US Based on investigation of the BU Libraries' staff, this work is free of known copyright restrictions Boston University
