    Morphology of Juniperus Cone and its Implications on Cone Evolution
    Author(s): Xin Wang* and Xiuping Xu

    Background:The basic cone unit in Pinaceaeis called Bract-Scale-Seed Complex (BSSC), in which the scale is supposed to be equivalent to an axillary shoot bearing ovules in Cordaitales. This correlation established by Florin provides a rational foundation on which an interpretation for the origin of cones in at least most Coniferalesis built, and may be called Florin model for convenience. Cupressaceaeis a family in Coniferales, in which the ovule-scale and its subtending bract are thought fully fused and hard to distinguish by external morphology. Results: Different from Pinaceaeand other typical conifers, Juniperus(Cupressaceae)appears not following Florin’s model closely. For example, the cone of Juniperusoxycedrus.. Read More»
