GLOSSOPTERIS. 77 



Frond large, elongate-lanceolate. Apex acuminate. Midrib 

 strong. Secondary nerves arched near their point of origin, and 

 forming two or more series of comparatively broad and short 

 polygonal meshes bordering on the midrib, then bent abruptly, and 

 passing very obliquely towards the margin in a direction almost 

 perpendicular to the midrib. Except near the midrib, the secondary 

 nerves are numerous and close, forming very narrow and trans- 

 versely-elongate meshes. The fronds measure 25-35 cm. or more 

 in length, and are often 4 cm. broad. 



This species is distinguished from 6. indioa by the strictly 

 lanceolate form of the frond, tapering more gradually towards the 

 apex and base ; by the contrast in the size and shape of the meshes 

 bordering on the midrib with those of the rest of the lamina ; and by 

 the very oblique course of the veins towards the margin at a short 

 distance from the midrib. It is only known from a very few 

 localities in India, of which the Nagpur district is the more 

 important. It is somewhat doubtful if the fronds from Cape 

 Colony ascribed to this species by Feistinantel are identical. 

 G. stricta has, however, been recently reoorded by Amalitsky 

 from the Permian (Northern Type) of Kussia. 



V. 7145. PL IV, Fig. 1. 



A slab showing four almost perfect fronds, of which the most 

 nearly complete is 25 cm. long. Part of one of these is figured 

 on PI. IV, Fig. 1, showing the midrib composed of a bundle of 

 parallel nerves, and the characteristic lateral nervation. The basal 

 portions of several other leaves are also seen.

46,705. A large slab sb owing several fairly complete fronds, 

 one of which is 23 cm. long, and almost perfect except the apex. 

 The contracted base is well seen. The midrib is broad, and is made 

 up of many parallel, anastomosing nerves. The lateral nervation 

 is strongly arched. Another almost complete frond on the same 

 slab measures 33 cm. long, and is 4 cm. broad at the widest point. 

 The nervation is less distinct than in the former specimen. 

 The margin is in places slightly incurved. Several basal portions 

 of fronds also occur on the same slab, as well as a median 

 portion showing the nervation excellently.
