iqiq] BASSLER—SPORANGIOFHORIC LEPIDOPHYTE 75 



latter, consisting of nothing but a nondescript blade with the 

 fragment of a pedicel attached, should have been selected for figur- 

 ing. I am able to figure here the cotype from Pittston, together with 

 several specimens from a large collection made by the writer in the 

 Youghiogheny Gorge below Swallow Falls, Garrett County, Mary- 

 land, one of them showing a somewhat impoverished sporangium 

 (partly cut away) still attached to the sporangiophore. Here, as 

 in each of the other already recognized species of this group, the 

 sporangiophore has been mistaken for a flattened sporangium. 

 The second species to be recognized was noted very briefly by 

 Lesquereux in 1880 in concluding remarks on L. linearifolium, and 

 it was not until 1884 that there appeared in the Coal Flora (3 : 785) 

 a brief specific description under the name Lepidophyllum cuUri- 

 forme. Two "forms " were there recognized but were not separated 

 even varietally. One from Cannelton is represented on pi. 108, 

 fig. 2, by a misleading illustration of an interesting specimen show- 

 ing 5 sporoph\lls attached in a series, and the other from Camp- 

 bells Ledge near Pittston, Pennsylvania, is so inadequately repre- 

 sented on pi. loj^figs. I J and 14, that the originals cannot be identi- 

 fied from the figures. Thus it came about that Lepidophyllum 

 cultriforme in America became, not the name for a species, but for 

 a group of cogeneric species characterized by httle else than oblong 

 "sporanges with their blades still attached to them," and any one 

 of several species may actually occur at localities from which 

 L. cultriforme is listed in the literature. This name will hereafter 

 be restricted to the species from Cannelton, of which we are refigur- 

 ing the specimen originally figured by Lesquereux and one other 

 from the Lacoe Collection. The ''form" from Campbells Ledge 

 becomes a new species, C. pugiatus; fig. 27 is from a specimen 

 from the Lacoe Collection. 



Potonie (18, p. 372) figured unsatisfactorily, without descrip- 

 tion, another species from Lower Silesia, under the name Lepido- 

 phyllum waldenbergense, and while Nathorst was engaged upon 

 the study of the Spitzbergen collections, he secured from the Royal 

 Prussian Bergakademie at BerHn the type material of the Silesian 

 species in the expectation that it might help him to interpret 

 certain structures in L. mirabile. In this he was disappointed,
