S PECIMENS of the Wealden fossil known as Tempskya 
S chimp eri, Cord., or Endogenites erosa , Mant., have often 
very little of their original structure preserved, sometimes 
„ a great deal. A striking difference in this respect is shown 
by sections of some specimens, which I collected near Bright- 
stone (in the Isle of Wight), and at Hastings respectively. 
Those from the first locality contain numbers of vascular 
bundles, whose tracheides have their scalariform thickenings 
perfectly preserved. In those from the second locality the 
outlines of the roots are distinguishable, but the xylem has 
entirely disappeared in nearly all cases. 
One of these latter specimens, in spite of the general 
obliteration of structure, contains a group of spores in re- 
markably good preservation. As spores do not appear to 
have been seen before in Tempskya , it may be worth while 
to describe them. 
A. C. Seward 1 has quite recently published a description 
of Tempskya , with a summary of previous work. It will,
