FIG. 2 in Dimorphic sexual expression and anisospory in Homalothecium sericeum Schimp. s.l. (Brachytheciaceae) in Portugal

FIG. 2. — Synthesis of the observations of sexual expression in the two Homalothecium Schimp. species (H. sericeum (Hedw.) Schimp. s.s. and H. meridionale (M. Fleisch. & Warnst.) Hedenäs) in Portugal (from LISU herbarium and/or field observations): A, female young colony without sporophytes, but with mixed small male plants; B, small independent male plants; C, independent male plants with caducous branches; D, independent male with perigonia in small branch; E, detached perigonium with two antheridia; F, G, dwarf males attached as tiny epiphytes to the female leaf, originated directly from spores, generally observed acquiring basal rhizoids (G) and eventually originating independent male colonies (as B); H, female plants with sporophytes and probably with dwarf males; I, green spores of two different sizes and aborted brown spores mixed (from capsules of LISU 262312; LISU 264096 and LISU 262054); J, part of a sample with caducous branches from a herbarium specimen. Scale bar: A, B, C, J, 0.8 cm; D, F, 500 µm; E, 300 µm; G, 400 µm and 600 µm; H, 0.4 cm; I, ± 50 µm.
