Fig. 8From: Further study of Late Devonian seed plant Cosmosperma polyloba: its reconstruction and evolutionary significanceReconstruction of Cosmosperma polyloba. The plant is considered to possess an upright, probably semi-self-supporting habit, with adjacent individuals entangled by their bushy, prickle-bearing fronds. Dimorphic fronds are helically arranged along stem, with bifurcate fronds in the majority, and scattered trifurcate fronds displaying median rachises; the connections between trifurcate fronds and fertile parts are speculativeBack to article page
