23. Panicum capillare L. 
Panicum capillare L. Sp. Pl. 58.1753. Linnzeus gives no description of his own 
but bases his name upon a phrase name of Gronovius@ which he quotes. Hence the 
type of P. capillare is the same as the type of Gronovius’s species, namely, Clayton 
no. 454, cited by Gronovius. This specimen, in the herbarium of the British Museum, 
is the common form of this species with broad blades and ample panicle; the spikelets 
are 2mm. long. Linnzeus also cites a phrase name and a figure from Sloane? as a 
synonym, the Sloane plant, also in the British Museum, being Panicum trichoides 
Swartz. On the strength of these two citations, Linnzeus gives the habitat as ‘‘Vir- 
ginia, Jamaica.’’ In the Linnean Herbarium there is a specimen of P. capillare 
from “H. U.’’ [Hortus Upsalensis] upon which Linnzeus has written the name. 
Milium capillare Moench, Meth. Pl. 203. 1794. Based on Panicum capillare L. 
Panicum bobarti Lam. Encycl. 4: 748. 1798. Lamarck cites the following: 
“Gramen paniculatum virginianum, locustis minimis Bobarti. Moris. hist. 3. p. 202. 
no. 33. Ex herb. Vaill.”’ It would seem that Lamarck 
is quoting the data on a specimen and not direct from 
Morison’s History, since the name Bobart nowhere occurs 
in Morison’s description or plate,¢ which applies to some 
species of Panicularia. In the Lamarck Herbarium is a 
fragmentary specimen of P. capillare bearing in Lamarck’s 
writing the data he quotes and in addition, also in his 
writing, the name ‘‘panicum Bobarti, Lam. dict.” Since 
Fie, 42.—P. capillare. From JY,amarck’s description applies to thisit is taken as the type. 
ae Bae in Gronovius Panicum capillare agreste Gattinger, Tenn. Fl. 94. 1887. 
No definite locality in Tennessee ismentioned. The type 
specimen, in the Gattinger Herbarium, is labeled in Gattinger’s hand ‘‘ Panicum 
capillare L. var. agreste. Fields, Ridgetop, Sumner Co., 14. IX. ’82.”’ Collected by 
Dr. A. Gattinger. It isa medium-sized specimen of P. capillare. 
Panicum capillare vulgaris[e] Scribn. Tenn. Agr. Exp. Sta. Bull. 7: 44.1894. No 
specimen is cited and no definite locality in Tennessee is given, but Scribner states 
_that this variety is the same as ‘‘the variety agreste of Dr. Gattinger.”’ 
DESCRIPTION. 
Plants erect or ascending, simple or sparingly branched at the base or sometimes 
above, 20 to 80 cm. high; culms papillose-hispid to nearly glabrous, the pubescence 
dense at the nodes; sheaths usually longer than the internodes, densely papillose-hispid; 
blades 10 to 25 cm. long, 5 to 15 mm. wide, scarcely narrowed toward the rounded 
base, hispid on both surfaces, the midrib prominent ; panicle densely flowered, large 
and very diffuse, often half the length of the entire plant, included at the base until 
maturity, the solitary or fascicled branches at first ascending, at maturity divaricately 
spreading, the whole panicle breaking away and rolling before the wind, the main
