AND THE ADJOINING TEERITOEY. 217 



Maegyeicabpus ? Valley of the Upper Liraay and else- 

 where in North Patagonia (No. 65, G. C). This is too imperfect 

 for description ; evidently allied to Jf. setosus, but the leaves are 

 different. The rhachis is tomentose, rigid, subspinescent, and 

 the leaflets shorter and more equal in size. It is probably M. 

 microphyllus of Niederlein, who has described several new Pata- 

 gonian plants in the ' Monatschrift zur Beforderung des Garten- 

 baus in den Preussischen Staaten ' for 1881. 



Maegyeicabpus Cuaeazii, n. sp. A native of Middle Pata- 

 gonia, extending from about lat. 41° S. to the Chubat, and south- 

 ward from that river (No. 155, G. C). This is a small plant 

 allied to Jf. alatus, Gill, in Hook. Miscell. iii. p. 385, but certainly 

 distinct. I subjoin brief diagnostic characters. 



A M. alato, Gill., differt foliolis subtus lanatis, stipulis (basi 

 petioli adnatis) fimbriato-ciliatis, calyce florifero sericeo-piloso, 

 fructifero in alas duas acutas expanso tuberculis acutis 2-3 inter- 

 mediis minuto. The fruit in this plant is very singular. In M. 

 alatus we find 4 or 5 membranous wings, recalling the appearance 

 of the fruit of Laserpitmm. In this the two rigid, pointed, wing- 

 shaped expansions are as long as twice the diameter of the fruit, 

 and the stiff, pointed, intermediate tubercles are more than half 

 that diameter in length. 



Acj:na splendens, Hook. Sf Am. Upper Limay, North Pata- 

 gonia (No. 90, G. C). Apparently brought down by the streams 

 from the Andes. 



AciENA mveiophylla, Lindl. Bahia Blanca, especially com- 

 mon about the lizcacheros, or bizcacha * warrens (No. 95, G. C). 



Pybus malus, L., var. Valley of the Upper Limay (No. 54, 

 G. C). The apple is said to have been introduced into this 

 region by the Spanish missionaries. It has thriven wonderfully, 

 and in the interior, especially between 40° S. and 40° 30', it forma 

 extensive groves and even small forests. It has developed two 

 varieties ; the fruit of one is sweet, of the other somewhat tart, 

 but not uneatable. My specimen has the leaves duplicate serrate, 

 velvety on the under surface. 



Saxifrages. 



Ribes magellanicum, Poir. Valley of the Upper Limay 

 (No. 91, G. C). I have seen no specimens from so northern a 

 locality.
