Abstract
Abstract The reproductive morphology of Grateloupia intestinalis (Cryptonemiaceae, Rhodophyta) from New Zealand is illustrated. Comparison is made to previous descriptions of Grateloupia and to Aeodes, a second genus of the family. Grateloupia intestinalis falls well within the range of typical Grateloupia species in the form of its vegetative construction, carpogonial branch ampullae, connecting-filament morphology and carposporophyte development. It differs mainly in the structure of its auxiliary-cell ampullae and the origin of the involucral filaments which surround the mature gonimoblast. The latter features show stronger resemblance to the type species of Aeodes than to the type species of Gratelopia. Chiang's classification scheme for the Cryptonemiaceae based on auxiliary-cell ampullar types is discussed, and it is proposed that G. intestinlis be maintained in Grateloupia rather than transferred to Aeodes or made a new genus on the basis of its anomalous ampullae. It is suggested that the variatio...
