of Germany, p. 134, unites the genera Phyllactidium and Coleochate together under the former name, regarding Coleochate as a species of Phyllactidium under the name of P. Coleochate. I suspect, from Hassall's description of his specimens of Coleochate, that he must have confounded this Alga and some of the Coleochate of Brebisson together. The two genera are most distinct, and I believe that Phyllactidium must be separated from Coleochate, which is allied to Bulbochate, and formed into a family by itself, characterized by the simplicity and uniformity of the cells, and the very peculiar fructification. I have compared the specimens from Manchester with authentic specimens of Phyllactidium and Bulbochate from Germany, which are in the British Museum collections. The Manchester specimens are larger and better developed, but not otherwise different. Phyllactidium is known from the discoidal form of Bulbochate by the frond being membranaceous, and of equal thickness in all its parts, and the cells similar on both sides of the surface. In Bulbochate, on the contrary, the upper surface of the frond is covered with trumpetshaped tubes, emitting a long seta, which are more abundant near the centre of the frond, the frond much thickened by them, and the fructification, which is well described by M. Brebisson (Ann. Sc. Nat. sér. 3; Bot. Journ. i. 29. t. 2), is very different, as I have proved by a microscopic examination of the fructification of the two genera. The fronds of Phyllactidium are regularly circular, and composed of very regularly-dispersed, forked, radiating lines of cells, until they arrive at a determinate size; then some of the cells on the margin diverge, and seem to form a centre for themselves, and the edge becomes proliferous; but this is a fact that does not seem to have been observed by the German algologist; and as the manner in which the cells dévelope is very various and peculiar, I must leave this part of the subject to another paper devoted to that object, which will be illustrated with figures, which Miss Staveley has most kindly prepared for me. PHÆNOGAMS AND FERNS COLLECTED IN OTAGO, NEW ZEALAND. BY W. LAUDER LINDSAY, M.D., F.K.S. EDIN., F.L.S. The following is a systematic enumeration of the Flowering-plants and Ferns collected by me in 1861 (October to December) on the eastern seaboard of Otago, in the settled districts between Dunedin, its capital, and the Clutha River. It may be desirable to explain that the collection was made in the spring of the Otago calendar,—at a time, therefore, when a considerable portion at least of its characteristic herbaceous plants was neither in fruit nor flower. Hence a proportion of the plants collected was unsuitable for identification; and hence also the collection was neither so large nor so interesting as it otherwise might and would have been. The species were determined by Dr. Hooker while preparing his Handbook of the N. Z. Flora (1864, part 1), in which work all the plants now enumerated are described, the new species for the first time. *The asterisk prefixed indicates plants which are also British.
