Morphometric, phylogenetic and biogeographic analyses ofPyrularia(Santalales), a parasitic disjunct lineage between eastern Asia and eastern North America

The tribe Xyloterini is widely distributed in the Holarctic realm. It is comprised of three rather small but well known genera. The largest of these, Trypodendron Stephens, consists of about a dozen species and occurs throughout the Holarctic realm; five of these species occur in North America. Dendrotrypum Schedl contains six species that are known only from eastern Asia. Xyloterinus Swaine contains one species from eastern North America.

By using morphology, karyology, pollen size, leaf flavonoids, ecological observations, and modification experiments, a new classification of the Galium trifidum group is proposed. Nine taxa in five species are recognized: (1) G. tinctorium, with ssp. tinctorium and sap. floridanum (new comb.) in eastern North America; (2) G. brevipes, a rare species centered in the Great Lakes region; (3) G. trifidum, with ssp. trifidum in northern North America. Asia, and Europe, ssp. columbianum (new comb.) in (north)western North America and (north)eastern Asia, and ssp. subbiflorum (new comb.) and ssp. halophilum (new comb.) in northern North America; (4) G. innocuum in southeastern Asia; (5) G. karakulense in central Asia.New chromosome counts of n = 12 and 2n = 24 are reported for G. tinctorium ssp. tinctorium and ssp. floridanum; and G. trifidum ssp. trifidum, ssp. columbianum, and ssp. subbiflorum.

Generic Relationships

Phenetic analyses of morphological characters of Leonticeae reveal three distinct groups of operational taxonomic units corresponding to genera. The genera Leontice and Gymnospermium of Eurasia are pheneticlly equidistant from Caulophyllum, which occurs in eastern Asia and eastern North America. On the basis of phenetic similarity, L. kiangnanensis is transferred to Gymnospermium as G. kiangnanensis.

AbstractTwo exotic species of Xyleborus (Coleoptera: Scolytidae) of Asian origin have recently been detected in the United States. Xyleborus pelliculosus Eichhoff has been collected in Pennsylvania and Maryland, and X. atratus Eichhoff from Tennessee, Georgia, Maryland, Virginia, and West Virginia. Descriptions of both species and a revised, illustrated key to members of the genus Xyleborus in eastern North America are presented. An explanation is proposed for the large numbers of recent introductions of exotic ambrosia beetles from eastern Asia into eastern North America.
