FIGURE 3. Histology of spermatozeugmata and sperm cells of Echinopsolus spp. a–c. E. acutus. a. Semithin cross section in centre of seminiferous tubule. b. Sperm bundles fill central space of seminiferous tubule. c. Longitudinal section through spermatozeugma showing sperm heads, mid-pieces and flagella. d–e. E. splendidus. d. Mass of sperm bundles. e. Longitudinal section through spermatozeugma. f–g. E. mollis. f. Mass of sperm bundles. g. Longitudinal section through spermatozeugma with poor structure preservation (alcohol conservation, no aldehyde fixation). f—flagellum; m—mid-piece; n—nucleus.
