Abstract
Anatomical study of the holotype of Picea cliffwoodensis Berry reveals a combination of features that conflicts with the assignment of this fossil cone to Picea or to any other modern genus. While the fossil appears to have been long and cylindrical as Picea cones, the resin canals of the scale base are all abaxial to the vascular tissue; this condition is unique to Pinus among modern cones. Several characteristics atypical of Pinus include the apparently thin scales, the thin vascular cylinder in the cone axis and the separate divergence of the bract trace and its associated scale trace from this vascular cylinder. Thus, this species does not belong to any of the modern genera of the Pinaceae and is transferred to Pityostrobus (Nathorst) Dutt.This publication has 2 references indexed in Scilit:
