Elongate much-forked variety, closely allied to S. bifurcatum, Lcsquereux. Bay de Clialeur (Logan). 4. S. Schlothcimil, Brongn. M. C, Sydney (Bunbury). 5. S. erositm, L. and H. M. C, Sydney (Bunbury) (Fig. 165, C). The last two species are regarded by Geinitz as varieties of S. emarginatum. A specimen of the last-named spf»p,ies in Sir William Logan's collection shows a woody jointed stem like that of Asierophjl- lites, giving oiF branches at the joints; these again branch and bear whorls of loaves. The stem shows under the microscope a single bundle of reticulated or scalariform vessels like those of some ferns, and also like those of Tniesiptcris, as figured by Brongnlart. This settles the affinities of these plants as being with ferns or with Lyco- podiacecc, rather than with EquisetacecE, as at p. 144 above. PiNNULARiA, L. and IL 1. P'mnularia capillacea, L. and H. M. C, Sydney (R. Browi). 2. P. Ramosisslma, spec. nov. (Fig. 165, D). More slender and ramose than the last. M. C, Joggins (J. W. D.). 3. P. crassa, spec. nov. Branching like P. capillacea, but much stronger and coarser. L. C, Ilorton (C. F. Ilartt). All these are apparently branching fibrous roots, of soft cellular tissue with a thin epidermis and slender vascular axis. Perhaps they are roots of Astc
