Descr.

Lignified ovuliferous complexes Spatulate outline with narrow, pedicellate base. Flattened, thickening distally but with thin, broad wings. Low-relief ridges on one or both abaxial and adaxial surfaces near, and subparallel to, the distal margin. A low-relief arcuate crest on the adaxial surface slightly proximal of adaxial ridge. Abaxial surface weakly convex, unkeeled. Margin entire, except for a single apical cusp formed from a medial protrusion of bract. Ovuliferous scale completely fused with bract. Seeds/ovules aligned on adaxial surface in a single transverse row. Three or more resin canals occur at the base; additional canals originate at or near the distal end of the pedicellate region de novo or via bifurcation to form two series: abaxial and adaxial. Distally, most canals arranged in a row close to abaxial surface; a smaller number arranged in a row close to adaxial surface. The medial abaxial canal enters the apical cusp; two canals delineate the lateral wing margins; canals terminate at or near abaxial ridge or distal margin.
