Abstract
Marked trees were studied over several years, certain characters being treated statistically. Among the Pruinosae are described: C. pruinosa fs. ciliata (p.792), glaberrima (p.793), and puberula (p.793), Missouri. These forms are characterized by close correlation of many trivial but constant characters. A discussion of the concept of species as it applies to Crataegus is included.This publication has 1 reference indexed in Scilit:
