ADDITIONAL MORPHOLOGICAL MEASUREMENTS OF ARCEUTHOBIUM SISKIYOUENSE AND A. MONTICOLA (VISCACEAE)

摘要

Additional morphological measurements were collected for Arccuthobium siskiyouense from a total of 15 locations in southwestern Oregon and northwestern California. Measurements were made for male and female plants growing on Put us attenuata, P. jeffreyi, and P. contorta var. contorta. Characters measured were similar on all three hosts, hot plant size was largest on P. jeffreyi and smallest on P. contorta var. con tort a. Additional morphological measurements were also collected for A. monticola, another endemic dwarf mistletoe oft he Klamath/Siskiyou Mountains. Results demonstrated that A. siskiyouense is morphologically similar to A. campylopodum and that A. monticola is morphologically, similar to A. californicum. Our measurements for flower characteristics are the first reported for A. siskiyouense and A. monticola.
