The last two species are regarded by Geinitz as varieties of S. emar 
gimatum. A specimen of the last named species in Sir William Logan's 
collection shows a woody jointed stem like that of Asterophyllites, giving 
off branches at the joints. These again branch and bear whorls of leaves 
The stem shows under the microscope a single bundle of reticulated of 
scalariform vessels like those of some ferns, and also like those of Zmesip- 
teris as figured by Brongniart. This settles the affinities of these plants,

All these are apeeielly branching fibrous stems or roots, of soft cellu- 
lar tissue with a thin outer bark, Perhaps reg are roots of Asterophyl- 
lites, or perhaps braiich lata of an aquatic plant.

a petiole nearly three inches long, and a fourth of an inch wide, epread- 
ing abruptly into a lamina, one side of which is much broader than 
other, and with parallel veins eid “it directly from the margin as ar 
a marginal rib. It appears to be doubled in at both edges, and is # 
ruptly broken off. It seems to be a new species, but of what affinities it 
is impossible to decide. N, flabellata Z. .M.C.
