—Petals with unequal poriferous zones, anterior poriferous zones usually four pore pairs longer than posterior ones in posterior paired petals; length difference in anterior paired petals often not as pronounced and showing more variation (in the studied specimens, posterior poriferous zones between 3 to 6 pore pairs longer than anterior ones); poriferous zone IIIa 2 to 3 pore pairs longer than zone IIIb; outer and inner pores of pore pairs equal in size and rounded in shape; poriferous zones of paired petals converge toward distal ends; posterior paired petals, anterior paired petals, and petal III extending up to 56%, 66%, and 61% of corresponding test radius, respectively; at their widest point, petals bear 7 to 9 tubercles across the interporiferous zone; phyllodes typically consisting of inner series with up to 4 pores per column, outer series with up to 9 pores; medial double row of up to 13 sphaeridial pits; buccal pores large and slightly elongated.
