| S. Y. Smith and R. A. Stockey 2001 | Ovulate cone, 6.5 cm long and 3.3 cm in di- ameter, cylindrical. Cone scale complexes helically arranged. Pith, 3–4 mm in diameter, parenchymatous with scattered scle- renchyma and peripheral ring of 28–37 resin canals (fig. 2). Vascular cylinder continuous, 0.5–1.0 mm, 27–43 tracheids, thick. Secondary xylem with 13–18 small-diameter resin ca- nals. Cortex 1.7–2.5 mm in diameter, with 27–30 dilating resin canals, mostly parenchymatous with sclerenchymatous outer zone 10–16 cells thick. Traces to ovuliferous scale and bract arising separately from vascular cylinder, with one resin canal from pith; ovuliferous scale trace abaxially concave; bract trace terete. Bract up to 10 mm long, triangular in cross section, with two lateral resin canals, separating from ovuliferous scale at margins. Ovuliferous scale at least 15 mm long, oriented at right angles to axis stele; resin canals both abaxial and adaxial to vascular strands. Two winged seeds per scale, ca. 3 mm long and 3 mm wide, wings at least 6 mm long. Thin layer of ovuliferous scale tissue attached to interseminal ridge encloses seeds and forms seed wing. |
