From the above it is evident that the phyllotaxis of Lepidodendron is extremely variable, as much so, perhaps, as that of those most variable plants in this respect, the Cacti. It is also clear that what has been enunciated by Frof. Ilaughton* as the law according to which the leaves of palaeozoic plants were arranged, viz. that of alternate whorls, does not apply to these ancient Lycopods.

{^Continued from page 145.)

Lactnca virosa, L. lledgebank by the roadside near Winford Firs, sparingly.

Hieraciiim vidgalinn, Fries. Bordwood Heath and a sandpit in j\Iorton Lane, Brading, are the only two localities known to me.

H. tridentatiim, Fries. Far more frequent. Centurion's Copse, Bern- bridge ; landslip near Luccombe (1857), Fan Common, New Copse, East Standen, etc. ; Nnnswood Copse, near Ningwood (J. G. Baker).

Campantda rotiaidifoUa, L. A monstrosity, with the corolla cleft into five narrow segments, was found at Freshwater, by my friend Mr. F. Bond.

Wahlenbergia hederacea, Reicli. On Buck's Heath, in a wet corner near to Kingston Church; also between File and Gladdice's Farms (Rev. Dr. Cookson).

Erythro'a Cenfaiiri/nn, L., var. capitata. Roam, et Sch. On Fresh- water Down and in the warren at Alum Bay, j)lentifully. This is, I be- lieve, the plant given in ' Flora Ycctensis ' as E. UltoraUs, which I have not succeeded in finding in the Isle of Wight.

Gentia>ia campestriH, L. On Colwell Heath close to the " Nelson Inn " (H. C. Watson, 1861), and gathered there in 1862 by myself. On Afton Down, Freshwater, R. Tucker, 1869 (.Journ. Bot. Vol. VIII. pp. 160.and 385).
