There are also a considerable number of smaller mistletoes belong- ing to the genus Arceuthobium which are widely distributed through- out the country. Of these there are two which may be especially mentioned: Arceuthobium cryptopoda Engelmann and A. pusiUuTn Peck. The former is known to occur in various sections of the Rocky Mountains and is injurious to a number of different conifer- ous hosts; the latter seems to be an eastern form, limited more or less closely to the Appalachian Mounta
