- Diagnosis
- The “inflorescence” is slightly curved, over 23 mm long and 7.5 mm wide at the base, tapering distally, with over 21 female units attached. A female unit
is composed of an ovule-container and a style-like projection at the top. The ovule-containers are up to 3 mm from the adaxial to abaxial side, up to 2 mm from side to side, up to 2.6 mm high. The column connects the base and the top of the ovule-container, 1.1—2.5 mm long, about 0.5 mm wide at the base and tapering to about 50 um wide at the top. More than three ovules are spirally arranged along the column at an angle close to 90 degree. A style-like projection 130-190 um wide and up to 0.9 mm long is inserted on the top of the ovule-container.
