Pinus glabra — Walter. Walter, in his Flora Caroliniana, gives 

 descriptions of five species of Pine, two of them, as new, viz : 

 Pinus squarrosa and P. glabra. His Pinus squarrosa is undoubt- 

 edly the tree now known as Pinus mitis, Michx. — (P. variabilis, 

 Ell. $k.~) His Pinus glabra has been lost to our later Botanists, 

 and its name has been excluded from the books. Pursh makes no 

 mention of either of Waiter's species, though his Flora was pub- 

 lished twenty-six years after the Flora Caroliniana. Elliott quotes 

 as a synonym, under his Pinus variabilis (P. mitis Michx.) Wal- 

 ter's P. glabra with a mark of doubt; and under his Pinus inops, 

 Aiton, he quotes the P. squarrosa, Walter, as a synonym, also with 

 a mark of doubt; and then makes this remark: "It {Pinus inops) 

 is said by Pursh to grow in Carolina, and it is probably one of the 

 two-leaved species described by Walter." Pinus inops does grow 

 in South Carolina, but I have never seen it lower down than Aiken, 

 where it is found on the poor chalk hills among the Kalmia 

 bushes. 



Though Walter's Herbarium is still in existence in England, in 

 the possession of the Fraser family, it can scarcely throw any light 

 upon this question from the meagreness of his specimens, the 

 whole collection occupying but a single volume. But I believe 

 that the obscurity which has rested on his two species, may now 

 be satisfactorily cleared up. 



There are but two two-leaved species of Pine which grow in the 

 neighborhood of Walter's residence, or within a hundred miles 

 perhaps of his collecting grounds, viz: P. mitis, Michx., (and the 

 tree which I suppose to be his P. glabra.) The Pinus inops, as I 

 observed before, does not grow in the low country. The former, 

 P. mitis, is very common in woods and old fields, and must have 

 been familiar to him. It could not have been included under his 

 P. palustris, P. lutea, or P. cedrus, for his characters of these spe- 

 cies forbid. The description of his new species is short, but the 

 "foliis geminatis, cortice scabro," identifies his P. squarrosa with 

 Pinus mitis, Michx.; and the "foliis geminatis, cortice glabro," dis- 

 tinguishes his P. glabra from all other species. The three others 

 now known, which contain two leaves in the sheath, are all rough 

 and scaly; this is remarkable for its smooth and whitish bark.
