acuminate, rarely oblong lanceolate or sub-rotundate, 
inequilateral, very rarely sub-symmetrical, the middle leaves 
larger than the lateral ones, and quite entire. Ordinary length 
about 32 millimetres, with a diameter of 16 millimetres. The 
internal margins of the lateral fronds somewhat expanded, 
furnished here and there with a broad indistinct dental lobe.

SaGENOPTERIS TasManica (Feistmantel). 
Frond compound digitate (?), with linear lobes, attenuate at 
the apex; costa distinct and rounded, veins emerging at an 
acute angle, forked, and once (so it seems in the fragments) 
anastomosing. A doubtful species resembling 8S. Phillipst, 
Lindley and Hutton of the English Oolite.

JEANPAULIA (Unger). 
Fronds coriaceous, arising from a cylindrical stem, 
flabelliform ; segments, which are linear, forking repeatedly, 
entire, more or less elongate. Veins numerous, rather 
prominent, equal, parallel, dichotomous with the divisions of 
the frond. Superior epidermis formed of elongate rect- 
angular or oblique cells ; lower side of hexagonal cells with an 
undulating margin, and numerous stomata. Fruit, ovate- 
pisiform. 
JEANPAULIA BIDENS (Tenison- Woods). 
Frond broadly flabellate ; segments somewhat short, often 
‘becoming broader towards the apex, and ending in a short 
wide bifurcation, or in a curved faleate, acute or acuminate 
point. Veins not conspicuous, numerous (6 to 10), parallel, 
not branching. The longest of the segments in the specimen 
figured is 55 millimetre, and the width is from 3 to 6 
millimetre.

Order. yYCopopiAcEs. 
Stem or rhizome bearing true leaves, either linear, or small 
and one-nerved, or reduced to minute scales. Spore-cases 
solitary or few together, sessile in the axils of the leaves or 
of the bracts of a terminal spike, either all similar or of two 
kinds, larger ones macro-sporangia, containing a few larger 
Spores or macrospores, and smaller micro-sporangia, containing 
numerous smaller often microscopic microspores, the differ- 
ences now generally admitted to be sexual.
