DescriptionTrees seasonally cladoptosic; trunk enlarged basally and often conspicuously buttressed; crown monopodial and conic when young, often becoming irregularly flattopped or deliquescent (branched and so divided that the main axis cannot be determined) with age. Shoot system conspicuously dimorphic, long shoots indeterminate, bearing individually abscising, linear to lanceolate leaves, short shoots determinate, abscising in autumn with their leaves, variable, intergrading, at one extreme pendent to horizontally spreading, bearing decurrent, narrowly linear and laterally divergent leaves in 2 rows, at other extreme strictly ascending to occasionally pendent, bearing short-lanceolate to deltate and tightly appressed leaves. Pollen cones in pendent panicles to ca. 25 cm, 2--3 mm, conspicuous in winter prior to pollination. Seed cones 1.5--4 cm.
