- Diagnosis
- Cylindrical strobili up to 40 mm
long, 10–14 mm wide. Cone axis slender, 0,8–1,2 mm
wide. Sporophylls arranged to cone axis in dense spiral.
Pedicels nearly perpendicular to the axis in the cone
base and at 60–75° angles in middle part and in the
cone apex. Pedicels with a keel, 2–4 mm long, distally
extended, up to 2 mm wide. Distal laminae triangular,
acutely induplicate to cone axis, 3,5–7 mm long,
1–2 mm wide at the bases. Sporangia rounded, ovate,
2–3 mm long, up to 0,8–1,5 mm wide. Microspores
triangular ovate in outlines, cavate, cingulizonate.
Spore diameter 29–36 (average 32) μm. Laesura length
2/3–3/4 of spore radius. Cingulum 1,5–2,8 (average 2)
μm wide. Spore zone 3 μm long on average, wide,
perforated. Distal surface of central body microgranulate,
microverrucate. Proximal surface microgranulate,
microspinate. Spore couture irregular.
