SOME FERNS FROM THE CARBONIFEROUS FORMATION. 147 



Fig. 19b shows one of the pinnae of a large pinnuled form of C. affinis. 

 This example, in the size of the pinnules, corresponds to Brongniart's Sphen- 

 opteris linearis* The nervation is beautifully preserved, and is shown in the 

 enlarged drawing, fig. 19#. 



Fig. 20. From West Calder, collected by the late Mr C. W. Peach. This 

 sketch shows one of the largest fertile pinnae of C. affinis with which I 

 have met. The pinna is destitute of foliage pinnules, and ramifies by a series 

 of dichotomies. At a are shown the ultimate branchlets, but the synangia 

 have become detached from their parent stalks, a few of which, however, are 

 seen at a and b. These consist of 4-5 sporangia. 



Figs. 21-22 are copied from the plate which accompanies Mr C. W. Peach's 

 paper in the Quart. Jour. Geol. Soc, vol. xxxiv. p. 131. Fig. 21 shows the 

 synangia attached to their supporting pedicels, and fig. 22 gives a single 

 synangium, which is enlarged at fig. 226 to show the five exannulate sporangia 

 of which it is composed. 



Horizon. — Hitherto only found in the Calciferous Sandstone series, where 

 in some localities it is plentiful.
