P. 734 : 



PLANTAGO CELORRHIZA Morris & Macl. 



This shows transitions to P. oxyphylla Speg. It is P. barbata (fide Kew.) 



P. SEMPERVIVOIDES Dusen. 



May be an extreme form of P. oxyphylla Speg. (fide Skottsb.) 

 P- 735 : 



P. HIRTELLA Kunth. 



Is likewise to be dropped, as not in the district. 



P. 736: 



P. MYOSURUS Lam. 



Is rather variable. Spegazzini in his paper, Nov. Addenda ad. Flor. 

 Patagon., pp. 77-78, has established the following varieties of P. myosurus 

 (a] latifolia, occurring in North Patagonia, in the district of the mouth o 

 Rio Negro ; (b] hirta, occurring in South Patagonia, between Puerto San 

 Julian and Rio Deseado; (c] taraxacoides, widely distributed in South 

 Patagonia, especially in the river valleys. 



P. monanthus d'Urv. is regarded by Skottsberg as not a distinct species. 



P- 737 = 



P. PATAGONICA Jacq. 



This species also is rather variable ; and Spegazzini has established 

 varieties of it, as follows : (a) typica, common over all Patagonia ; (6) gra- 

 cilescens, occurring in North Patagonia at the confluence of Rio Limay 

 and Rio Neuquen, also in the northern section of the east coast, as at 

 Puerto San Bias; (c) minuscula, occurring along Rio Negro and along 

 Rio Chubut, and Rio Sta. Cruz.

2O. P. MACROSTACHYS Dene.

 (60 cm.), and the structure of the flower. Leaves oblong-elliptical, 

 toothed, or sublobate, 7-9-nerved (6 cm. broad) glabrous. Peduncles 

 hairy above, much exceeding the leaves. Spike long, bracts lanceolate 

 ciliate. Calyx-leaves unequal; the posterior rounded. Corolla-lobes 

 cordate acuminate. Seeds 3.
