436 PROCEEDINGS OF THE ACADEMY OP 



Catalogue of Carboniferous Plants in the Museum of the Academy of Natural 

 Sciences, with corrections in Synonymy, descriptions of new Species, &c. 



BY HORATIO C. WOOD, JR. 



la the ensuing enumeration, it will be seen, that we first give our own de- 

 cision, followed occasionally by remarks on synonomy, &c; then the number 

 of specimens with labels previously affixed, in quotation marks ; then the locality, 

 as far as known followed either by the name of the donor, or of the collection 

 to which they formerly belonged, and their number in that collection. 



The Academy is indebted to Dr. T. B. Wilson for the duplicates of the " Bristol 

 Institute Collection," which form the bulk of the specimens. We do not know 

 whether the numbers on them coincide with the original collection or not. 



Those presented by Mr. J. P. Wetherill are especially interesting; many of 

 them being the types of Steinhauer, and all probably having belonged to that 

 author. They are labelled with Steinhauer's names, in the hand writing of 

 Dr. Samuel Geo. Morton. 



Besides those here enumerated, there are in the cabinet of the Academy a num- 

 ber of European vegetable reliquse from various formations. These we had pur- 

 posed arranging and cataloguing conjointly with the carboniferous ; but owing 

 to the press of other engagements must leave them till some future day. 



We know of but one other foreign collection in the United States, and the 

 partially arranged American suite of the Academy is large and increasing from 

 day to day. We think it highly important that there should be a standard 

 collection in this country, where investigators may deposit these types, and by 

 comparison with which any disputes that may arise may be settled. The city 

 of Philadelphia, the emporium of the coal trade, is certainly the proper place 

 for this. Moreover, the collection of carboniferous plants, (native and foreign,) 

 is probably much the finest in the country, numbering about a thousand speci- 

 mens. We would therefore suggest to authors the propriety of sending, as far 

 as practicable, types of their coal plants. We would also ask those living in 

 the coal region, or engaged in the trade, to send specimens to the Academy. 

 and thus forward the best interests of botanical science and practical geology. 



Ord. EQUISITACEA. 

 Equisktites, Sternb. 



E. macro do n tu s , n. sp. ? Stem simple, articulated, obsoletely costate ; 

 articulations short, swollen at the joints ; sheaths multidentate ; teeth longer 

 than articulations, contracting at their base, expanded (and united ?) above, 

 then rapidly contracting, and terminating in a greatly elongated setaceous point, 

 (? furnished on one border with a second short setaceous point.) Fructification 

 not preserved. 



Our specimen is a flattened impression on coal shales, the terminal sheath 

 only being distinct. It is impossible to say with certainty, whether the second 

 points belong to the large teeth, or whether they are the terminations of a 

 smaller set placed between them. 



Calamites,* Suckow. 

 C. radiatus? Brong. 



1 specimen " C. radiatus ?'' In Pennant, Bris. Ins. "Coll. No. 64. 



C. decoratus, Art. 



1 spec. Red Vein, Abersychan. T. B. Wilson, M. D. 



2 spec. " Phylolithus sulcatus," Pudsy. J. P. Wetherill. 



*Calamites was applied in 1751, (Guett. Mem. Ac.Sc. Par.) to a genus of fossil corals, 

 but as the name is considered pre-Linnsan by authorities in that department of palaeonto- 

 logy, and replaced by Syringopora, Goldfuss, of course we do not change it as applied to 

 fossil botany.
