V 22. Panicum philadelphicum Bernh. 
Panicum capillare sylvaticum Torr. Fl. North. & Mid. U. S. 149. 1824, not P. 
sylvaticum Lam. 1798. ‘‘In dry woods near New York.’’ The type is in Columbia 
University Herbarium. 
Panicum philadelphicum Bernh.; Trin. Gram. Pan. 216. 1826. This is mentioned 
by Trinius as a variety of P. capillare, similar to his £ [P. flezile], but with spikelets 
only acute [not acuminate as in the others], ‘‘misit s. n. 
Pan. philadelphici sibi cl. BERNHARDI.’’ Enough description 
is given to technically constitute publication. Nees later@ 
describes the species more fully. The type, in the Trinius 
Herbarium, is from Philadelphia, sent by Bernhardi. On 
f the same sheet is a specimen of P. jflexile from the same 
source, but a drawing by Trinius with the name of P. phila- 
delphicum indicates which specimen is the type.

not apply to this species and a specimen in the Fournier Herbarium, cited by him 
under this name, is P. bulbosum. 
Panicum capillare minimum Engelm.; Gattinger, Tenn. Fl. 94. 1887. No definite 
locality in Tennessee is mentioned. The type in the Gattinger Herbarium bears the 
name in Gattinger’ s writing and the data ‘‘Greenbriar, Sept. ’78. A. Gattinger.”’ 
This name is initialed ‘‘F. L.8.’’ by Scribner, hence the same name published¢ 
later by him is also based on this specimen.

1900. Based on P. capillare minimum Engelm. 
Panicum soboliferum Tuckerm.; Scribn. & Merr. Rhodora 3: 106. 1901. This is
