MACLOSKIE: REVISION OF FLORA PATAGONICA.

Add Macl., p. 146: 



PANICUM LANATUM Swartz. 



Culm 120 cm., branching, jointed. Leaves 15 cm., ovate-lanceolate, 

 mucronate, with rough woolly sheaths. Panicle compound, 15 cm., its 

 rays spreading, flexuose ; spikelets with capillary pedicels. Outer glume 

 half as long as the inner, villous. Valves ovate, pale. 



Falkland Is.; Jamaica. D. 



Panicum chloroleucum Gris., Macl., p. 164, should be deleted, being a 

 synonym of P. urmlleanum Kunth. 



Add Macl., p. 164: 



Panicum insitlare (L.) Mey. var. typicum. (Syn. Paspalum leucop/ueum 

 H.B.K. in Macl., p. 162.) N. Patagonia, in the vicinity of Carmen de 

 Patagones. 



P. Mrvilleamim Kunth. is also stated (Macl., p. 164) to occur in the 

 Falkland Islands ; perhaps a mistake. 



P. MAGELLANICUM Lam. Macl., p. 164. 



Probably all the species of Panicum in this region should be deleted. 

 It is quite probable that no species of that genus occurs in the southern 

 part of the district, and that some mistake occurred, in which a plant col- 

 lected in a warmer part of the globe was substituted ; such a supposition 

 will explain the fact that the plant was never recovered again from this 

 region. D. 



SETARIA Beauv. Macl., p. 164. 



S. CAUDATA (L.) Beauv. 



This species, though closely allied to S. setosa Beauv., is by no means 

 identical with it. (Nor is S. setosa known to occur in our district, not- 

 withstanding Macl., p. 165.) 



PHALARIS L. Macl., pp. 167, 168. 



Add Phalaris canariensis Linn. Leaves lanceolate ; nodes glabrous, 

 the sheaths rough above. Panicle ovate, 4 cm. long ; pedicels very short. 

 Glumes navicular, entire, 3-nerved. 



Patagonia, Santa Cruz Emporium, introduced. 



ANTHOXANTHUM L. 

 A. ODORATUM L. Macl., p. 166. 

 The species is noticed in the Falkland Is., as introduced.
