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. 



A SUFFLEMENT TO THE 'FLORA VECTENSIS.' 

 By Alexander G. More, F.L.S., M.R.l.A. 



{^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). 



*Ciiscuta Trifolii, Bab. Apparently increasing. Mr. Fristo says that 

 it is becoming a pest in the Clover fields about Whippingham. I have 



* 'Manual of Geology ' (London, 1866), pp. 213 and 245.
