GLOSSOFTERIS. 57 



V. 7291. A well-preserved apical portion of a frond. The 

 midrib hardly extends to the obtuse apex. The meshes are fairly 

 broad and polj'gonal. 



Port Stephens. Odinheimer Coll. 



39,188. A slab showing several fronds which vary greatly in 

 size and shape. The best example is a complete elongate-elliptical 

 frond, 19 - 5 cm. in length and 60 cm. broad at its widest point. 

 The nervation is not, however, very clear. Other and smaller 

 fragments are more spathulate, some being apical, and others basal 

 portions. In some of these the nervation is better preserved. 



Newcastle. Presented by Capt. Sir JE. Home (?), 1859. 



V. 648. A large triangular slab containing hundreds of impressions 

 of small fronds of G. Broivniana, of an average length of 5 cm. 

 and a greatest width of 13 mm. The nervation is, iu most cases, 

 not well preserved. This specimen affords excellent material 

 for a study of the variations in shape and size which occur in 

 fronds of this species. Most of these fronds are probably immature. 

 An occasional scale-frond also occurs. 



Old Lambton Colliery, near Newcastle. Purchased, 1884. 



V. 7350. A slab showing several fronds varying greatly in 

 shape, some being spathulate, others more oval. There is also 

 considerable variation in the breadth of the meshes. The nervation 

 is very clear. On the back of the specimen, there are some more 

 imperfect fragments, and also a scale-frond. 



Old Lambton, near Newcastle. 



V. 2837. A slab of shale showing two well preserved fronds and 

 the basal portion of another. The meshes are fairly broad, and the 

 nervation clear. The rock, as in many other specimens, is largely 

 composed of impressions of fronds of Ghssopteris. 

 Nobby's, Newcastle. 



Presented by the Australian Commissioners of the Indian ani 



Colonial Exhibition, 1886. 



V. 4283. A badly preserved frond, but an interesting specimen, 

 showing the gradual tapering of the frond at the base towards the 

 point of attachment. A specimen of the rhizome ( Tertebraria) 

 occurs near this frond. 



Tort Stephens. Odinheimer Coll.
