FIG. 4 in Dimorphic sexual expression and anisospory in Homalothecium sericeum Schimp. s.l. (Brachytheciaceae) in Portugal

FIG. 4. — Graphical presentation of spore sizes from 12 different capsules of selected samples. Variation of spore sizes in six capsules of Homalothecium sericeum (Hedw.) Schimp. s.s (left graphics) and six capsules of H. meridionale (M. Fleisch. & Warnst.) Hedenäs (right graphics). Numbers on the vertical axes indicate frequencies, and those on the horizontal axes indicate diameter values in µm. The dashed line represents the tendency line bimodal distribution of diameter values. The dark grey horizontal bars in left side of each histogram, indicate the size range of collapsed spores, measured in the same capsule (capsules from LISU*collection, displayed sequentially for localities from the North to the South of Portugal).
