ABSTRACT
Based on analyses of terpenoids, nrDNA and trnC-D SNPs as
well as morphology and ecology, a new cryptic species, Juniperus
maritima, from the Puget Sound region is recognized. The species,
previously included in J. scopulorum, is characterized by having seed
cones that mature in one year (14-16 months), seeds usually exserted
from the cone, obtuse scale leaf tips, usually reniform seed cones, scale
leaves overlap less than 1/5 the length, and branchlets smooth and
reddish-brown. Called the seaside juniper, it grows on rocky areas
(rarely sand dunes) near the sea, in Puget Sound.
KEY WORDS: Juniperus maritima, Puget Sound, J. scopulorum, J.
