    Figs. 111-116. Fossombronia echinata Macvicar. 111. SEM micrograph of plant showing compact growth and an immature sporophyte (arrow); scale bar = 100 µm. 112. Higher magnification of a branch showing the leaf decurrency, oblate leaf shape and a group of 3 antheridia (an) basal to a group of 2 archegonia (ar); note that the long decurrent appearance of leaves is artifactual, caused by folding during preparation; scale bar = 100 µm. 113. SEM micrograph of a branch with immature sporophyte and caulocalyx; note the antheridia (an) near the base of the caulocalyx; scale bare = 100 µm. 114. Higher magnification of the caulocalyx in fig. 113, showing the lobate mouth and archegonia (ar) near the branch apex; scale bar = 100 µm. 115. OM micrograph of a leaf; scale bar = 100 µm. 116. OM micrograph of median leaf cells; scale bar = 10 µm.Figs. 110 - 116. from the lectotype of F. echinata, Nicholson s.n (CGE).
