disposed at varying angles of divergence from the midrib, curving and 

 anastomosing near the margin or irregularly connected by oblique or 

 curved tertiaries. 



This species is somewhat suggestive of 8. oregonianus Knowlton (Bull. 

 IT. S. Geo!. Survey, No. 204, p. 79, pi. xv, fig. 3) and to 8. oltusifolius 

 Lesq., (Ann. Rept. IT. S. Geol. and Geog. Surv. Terr., 1873, p. 419, Tert. 

 M. pi. xlix, figs. 8-11; Cret. and Tert. Fl. pi. xlviii, figs. 5-7) but differs 

 in the more tapering base. It is possible that all specimens might not 

 exhibit this characteristic to the same extent, in which case the similarity 

 with S. oregonianus would be very close. 



Occurrence. — Sunderland Formation. Near the headwaters of Is- 

 land Creek, Calvert County.

Description. — Several leaves, apparently identical with the one figured, 

 were found in the Talbot swamp deposits at Drum Point and Bodkin 

 Point, but with one exception it was found to be impossible to preserve 

 them long enough to permit of their being drawn. The specimen figured 

 is from the former locality.
