[P. calliphyllum Ashe. 



Hitchcock says of P. calliphyllum (Contr. U. S. Nat. Herb. 15:178. 1910): 

 " 'Type material collected by the writer at Watkins, Lake Seneca, N. Y. Aug. 1898.' 

 [Ashe.] The type could not be found in Ashe's herbarium. In the National 

 Herbarium is a specimen collected by Ashe ' Near Ithaca, N. Y.' which Mr. Ashe has 

 stated orally is from the published locality and is a duplicate type." This species 

 has not since been found in central N. Y.] 



16. P. xanthophysum Gray. 



Dry sandy or gravelly open woods, in acid soils ; rare. July-Aug. 10. 

 Thatcher Pinnacles (D. !) ; summit of South Pinnacle, Caroline (D.) ; "Danby, 

 Coville in 1885" {Hitchcock & Chase). 

 Que. to Minn., southw. to Pa., including the northern Coastal Plain. 



[P. macrocarpon Torr. (See Rhodora 14:184. 1912. P. Scribnerianum Nash.) 



Hitchcock (Contr. U. S. Nat. Herb. 15:284. 1910) cites a specimen "Ithaca, 



Ashe." This species has not since been found here. Ashe's specimens of that period 



were sometimes labeled " Ithaca " or " near Ithaca " when they really came from 



Watkins (see above, under P. calliphyllum).] 



17. P. clandestinum L. 



Low woods and thickets along stream banks, usually in sandy, more or less acid 

 or at least neutral, soils ; rare. July-Aug. 



Alluvial bottom land along the old southern stream bed of Fall Creek, Forest 

 Home; Renwick woods (W . W. Rowlee) ; "border of the woods near the brook 

 north of the ' Nook.' Possibly introduced here " (D.) ; n. of Montezuma village. 



N. S. to Kans., southw. to Fla. and Tex., including the Coastal Plain. 



18. P. Boscii Poir. 



Gravelly banks in dry woods, in neutral or subacid soils ; rare. July. 



Coy Glen (£. M. Cipperly, 1904!, F. P. Metcalf, 1914) ; n. side of Beebe Lake, 

 1916 (F. P. Metcalf). 



Mass. to Okla., southw. to Fla. and Tex., including the Coastal Plain. 



The specimens listed above are pubescent, the Coy Glen plants very slightly and the 

 Beebe Lake plants much more so (var. molle (Vasey) Hitchc. & Chase), but this 

 distinction seems of little taxonomic importance. 



19. P. latifolium L. 



Dry open woodlands, in sandy or gravelly neutral or acid soils ; frequent. June 

 20-July. 



On the hills s. w. and s. e. of Ithaca, on the ravine crests and the crests of the lake 

 cliffs, and in the sands n. of Cayuga Lake ; rare or absent in the McLean region 

 and on the clays and richer soils back from the lake shore.
