But after studying the specimens in the Agardhian Herbarium and in the Trinity College, Dublin, I am strongly inclined to refer my plant to the present species. A question, however, is on the nemathecia described by Haryey. In mv specimens, the tetraspores are found sitting among the epidermal cells, dispersed everywhere in the upper segments and never in any form of nemathecium. They divide zonately and are very small, the longer axis being not much larger than the height of the epidermal cells (see figure). Harvery's type specimens may be distinguished into two forms. One is subdichotomousl^' laciniated, with the breadth of segments nearly equal for the whole length. This form is excellently shown In Pliyc. Austr., PI. 210. The other is irregularly laciniated at the base, palm- ately lobed above, with the segments broad and imbricated with the neighboring ones. On the under surface of the basal segments there are many papillose rhizoidal processes. The illustration by Kutzing in Tab. Phvc, , may be taken as to re- present this form. With this my specimens coincide very well. Harvey's specimens had ovate elevations here and there on the surface of frond. These he regarded as immature nemathe- cia and consequently he brought the plant near by Curdiea.
