| Title | Paper, 'Studies in the morphology of spore-producing members. Preliminary statement on the lycopodinae and ophioglossaceae' by Frederick Orpen Bower |
| Date | 1891 |
| Description | Bower writes: 'It is currently held that the sporophyte, or neutral generation in archegoniate plants, is the result of elaboration of the zygote: that while in certain Algae the zygote simply divides to form a number of spores (carpospores), in the lower Bryophyta there has been a differentiation of an external, sterile, and protective wall, distinct from the internal mass of spores. The higher Bryophyta show a larger proportion of sterile tissue, which in them composes the seta, columella, and wall, while the sporogenous tissue is comparatively reduced in bulk, though still forming one united band.'
