23. Panicum capillar e L. 



Panicum capillare L. Sp. PL 58. 1753. Linnaeus 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 2 mm. long. Linnaeus also cites a phrase name and a figure from Sloane & as a 

 synonym, the Sloane plant, also in the British Museum, being Panicum Irichoides 

 Swartz. On the strength of these two citations, Linnaeus gives the habitat as " Vir- 

 ginia, Jamaica." In the Linnaean Herbarium there is a specimen of P. capillare 

 from "H. U." [Hortus Upsalensis] upon which Linnaeus 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: 

 u 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, c 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. diet. " Since 

 Fig. 42.-P. capillare. From Lamarck's description applies to this it is taken as the type, 

 type specimen in Gronovius -. . 7 , , „ , . . _. „,, „ " 



Herbarium. Panicum capillare agreste Gattmger, Tenn. Fl. 94. 1887. 



No definite locality in Tennessee is mentioned. The type 

 specimen, in the Gattinger Herbarium, is labeled in Gattinger's hand "Panicum 

 capillare L..var. agreste. Fields, Bidgetop, Sumner Co., 14. IX. '82." Collected by 

 Dr. A. Gattinger. It is a medium-sized specimen of P. capillare. 



Panicum capillare vulgaris^] 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
