Original protologue

Ovulate cones, up to 7.8 cm long and 3.7–7.6 cm wide (exclusive of bracts); displaying small domeshaped receptacle with anastomosing vascular bundles. Receptacle with resinous cells; interseminal scales with 1–2 resin canals; resinous tissues absent from ovulate sporophylls. Sporophylls and interseminal scales 2.0–5.3 cm long. Seeds 12–19 mm long, 2.1–4.1 mm wide, with micropylar canal terminating just below apices of 5–6 encircling interseminal scales; round at apex, becoming distinctly 4–5 winged at base of micropylar tube. Wings produced both by sclerotesta and sarcotesta; greatly accentuated by sarcotesta apically, diminishing basally, absent from chalaza. Sporophyll with highly convoluted vascular strand immediately below seed; straight basally.


The specific epithet maccafferyi is proposed for Dane McCaffery, Nanaimo, British Columbia, who generously provided the holotype specimen for study.
