Width of the stalk decreasing towards beginning of fertile part of the cone. The stalk bears coarse prolonged ribs. Fertile part of the axis is considerably wider (in two times) than the stalk. Surface of fertile part of the cone is also longitudinally striated, but in less extent tnan the stalk. Synangia are petalomorphic, consist of 8-9 sporangia. Sporangia are elliptic with round or, rarely, acute apexes. Surface of sporangia bears fine prolonged ribs. Cuticle thin, with anisogonal cells prolonged in polar direction along sporangium, formed spiral pattern. Cell size 30 x 50 pm. Cell walls slightly curved.
