142 PHYLLOPTERIS 
V. 2353. Small piece with carbonaceous substance preserved ; 
shows an unevenly-lobed margin. In the venation areole occur 
oval or roundish projections, probably sori. Cf. Schenk’s figure of 
Hausmannia dichotoma, Dunk., also Nathorst’s enlarged drawing 
of Dictyophyllum Nilssoni, Brong., var. intermedium.’ Eccles- 
bourne. Rufford Coll. 
V. 2815. On one of these specimens is a broad vein from which 
secondary branches are given off at right angles, and the spaces 
between are traversed by a network of finer veins. Length of 
fragment 3°5 cm.; intervals between the large secondary branches 
2mm. Cf. Hausmannia dichotoma,? Dunker, and Schenk’s figure 
of Dictyophyllum Roemeri,* Schenk. Ecclesbourne. ufford Coll. 
Genus PHYLLOPTERIS, Brongniart. 
[Tableau, 1849, p. 22.] 
Brongniart proposed this new genus for certain forms of leaves 
previously referred to Glossopteris and Teniopteris, but which differ 
from these two genera in the character of their venation. The 
leaflets included in this genus are considered by Brongniart to 
belong to pinnate or digitate fronds, more or less lanceolate or 
linear in shape, with well-marked midrib, and very oblique 
dichotomously branched veins which do not anastomose to form 
a reticulum. Glossopteris Phillipsii, Brong., is one of the plants 
included under Phyllopteris; it is pointed out that Phillips’ figure ‘ 
incorrectly represents the venation as reticulate, also that the 
plant described and figured by Lindley and Hutton as Glossopteris 
Phillipsir® is a true Sagenopteris. 
Zigno® and Saporta’ adopt Brongniart’s genus, and the latter
