126 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



Andropogon ischaemum L. Sp. PL 1047. 1753. 



This is an Old World plant, but the only specimen in the herbarium is marked 

 "11 Ischaemum" and is A. furcatus MioliK . This should not be taken as the type 

 of the species, since it is not the plant Linnaeus describes. 



Andropogon insulare L. Syst. Nat. ed. 10. 2: 1304. 1759. 



The type specimen is from "Br." It is Valota insularis (L.) Chase (Panicum leu- 

 c ophaeum H. B. K.). After his own description Linnaeus cites Sloane's plate 14, 

 figure 2, which is also this species, but he does not use Sloane's diagnosis. 



Andropogon barbatum L. Syst. Nat. ed. 10. 2: 1305. 1759. 



The type specimen, from "Br," agrees with Linnaeus's description. It was first 

 marked Andropogon faseiculatum; the specific name was scratched and barbatum 

 written above. This latter name is also scratched and polydactylon written after. 

 Both changes appear to have been made by Linnaeus. The plant is Chloris polydactyla , 

 (L.) Sw., as described in Grisebach's Flora. a Linnaeus here cites Sloane, plate 65, 

 figure 2, which he earlier referred to Andropogon faseiculatum, but which in fact is 

 Chloris polydactyla. Later b Linnaeus changes the name barbatum to polydactylon, citing 

 Browne and also the plate of Sloane just mentioned. Upon these grounds Nash forms 

 the name Chloris barbata (L.) Nash,c but according to the recent code of nomenclature 

 this name can not be used on. account of Chloris barbata (L.) Sw. Fl. Ind. Occ. 1: S'OO. 

 1797, which is Andropogon barbatum L. Mant. 2: 302. 1771, from the East Indies. 



Andropogon faseiculatum L. Sp. PL 1047. 1753. 



Munro d states that there are two Linnaean specimens marked with this name, one 

 being Eleusine indica and the other Pollinia ciliata. The only plant from America 

 bearing this name in the Linnaean herbarium is the sheet mentioned above under 

 Andropogon barbatum, in which the name faseiculatum was scratched. But this speci- 

 men is marked "Br" and presumably was not available when Linnaeus drew up his 

 original description, though the description applies well to this specimen. This 

 specimen is, no doubt, the basis of the Browne synonym cited in Sp. PL ed. 2. 1483. 

 1762, under A. polydactylon. Linnaeus* cites Morison, Gramen Dactylon Indicum, 

 etc., but this is an Indian plant and has villous spikes, while Linnaeus remarks that 

 the spikes in his specimen are glabrous. The habitat is given in the original pub- 

 lication as "Indies," that is, the West Indies. Linnaeus/ doubtfully refers here 

 Sloane, plate 65, figure 2, which is Chloris polydactyla (L.) Sw., cited later under 

 Andropogon barbatum g and A. poly 'dactylon. ,h We may therefore eliminate these 

 two synonyms of Morison and Sloane, which are the only ones given. In the 

 Systema Naturae* Linnaeus retains A. faseiculatum along with his new A. barbatum 

 to which he transfers the Sloane citation. In the Pugillus Jamaicensiumi he does 

 not mention A. faseiculatum, but he gives A. barbatum, which is founded on the 

 Browne specimen. In the second edition of the Species Plantarum he still retains 

 A. faseiculatum with the original description and the Morison citation, introduces a 

 new citation (Browne Jam. 365), and changes the Sloane citation to plate 69, figure 2, 

 which is Paspalum virgatum. It is evident that the type of A. faseiculatum is not 

 from America in spite of the continued reference to American citations. 



Holcus laxus L. Sp. PL 1048. 1753. 



The type specimen is a Gronovian plant numbered 589, upon which Linnaeus has 

 written "6 laxus." It is Uniola laxa (L.) B. S. P. (Uniola gracilis Michx.). Clay- 

 ton no. 589 in the Gronovian herbarium is the same.
