Abstract

This paper deals with the development of the sexual organs (in their respective nemathecia), the carposporophyte and the tetrasporophyte of Polyides caprinus in the British Isles. The carposporophyte is of the 'diffuse type' and resembles that of some other Cryptonemiales-;and some Gigartinales (sensu Kylin) in essential features. The life-history is of the Polysiphonia-type on the coast of Wales, as male, female, and tetrasporic plants occur in nature and reduction division takes place in the tetrasporangium.
