46 PATAGONIAN EXPEDITIONS: BOTANY. 



There is not the slightest doubt of the identity of A. superbiens and 

 Poa fuegiana. I have examined a specimen of the former, which is num- 

 bered 1194 in W. Lechler's Plantce Magellanicce and I find it to be iden- 

 tical with the latter. 



Add Macl., p. 199 : 



AIRA ELATIOR Steud. ( = Deschampsia Kingii}. 



Root stout, cespitiferous. Culms 90 cm., erect, smooth, reed-like, long- 

 sheathed, sheaths striate ; ligules obtuse, entire. Leaves narrow, flat, 

 complicate, 30 cm. Panicle contracted, 20 cm., rays capillary, whorled, 

 dividing upwards, with few spikelets ; these 5 mm. violet-silvery, glabrous. 

 Glumes exceeding the paired flowers, one flower sessile, one pediceled, 

 with silvery hairs. Lower scale obtuse, apically awned. 



Chili ; S. Patagonia, Magellan, Punta Arenas ; Fuegia. D. 



A. VERSICOLOR Roem. & Sch. 



Root fibrous, cespitiferous; culms sheathed, leafy, terete, 15-22 cm. 

 Sheaths long glabrous; leaves setaceous, the radical 6 cm., flexuose, 

 spreading. Culms erect, rigid, obtuse. Panicle contracted, 3 cm. pedi- 

 cels capillary, torted ; glumes unequal ; valves unequal, the lower rough 

 at nerves, pilose at base, apex entire. Awn twisted, arising above the 

 base, long. 

 Patagonia ? 



A. VESTITA Steud. Macl., p. 199. 



This species should also be deleted, being synonymous with Deschamp- 

 siaflexuosa (L.) Trin. 



A. vestita has No. 1193 in the above collection of Magellan plants by 

 W. Lechler. The specimen I have examined agrees with Deschampsia 

 flexuosa, at least it approaches its variety or, properly speaking, form 

 montana (L.). 



DESCHAMPSIA Beauv. 



D. ACIPHYLLA (Franch.) Speg. Macl., p. 200. 



Has a far wider distribution than stated by Macloskie. In addition to 

 Fuegia and the Magellan Territory, it is also found in W. and N. Pata- 

 gonia. 



Here should, probably, be placed Deschampsia tenella Phil, as a 

 variety of D. aciphylla. According to Spegazzini cf. Speg. Add. Flor.
