158 PATAGONIAN EXPEDITIONS: BOTANY. 



TRIFOLIUM MINUS Sm. (partim T. FILIFOLIUM Linn.). 



Flowers in ovoid pedunculated heads ; petals scarious, becoming yellow, 

 at length reflexed. Leaflets obovate to obcordate, finely denticulate, the 

 terminal petiolulate ; stipules broad-ovate, as long as petioles ; peduncles 

 long and filiform. Flowers subumbellate, sessile; calyx-segments une- 

 qual, the 2 upper very short. Legumes i-2-seeded ; seeds oblong-ovate. 



Europe, Falkland Is., introduced. 



T. POLYMORPHUM Poir. 

 The statement of its occurrence in Magellan seems to me doubtful. D.

A. AMUNATEGUII (Phil.) Speg. 



Syn. Phaca amunateguii Phil. Anal. Un. Chil., p. 31. 



S. Patagonia, near Sta. Cruz Emporium ; Puerto San Julian ; Central 

 Patagonia, Lago Musters ; along Rio Carren-leofu. 



Macl., p. 504: 



A. DUSENII (Dusen) Macl. 



(Syn. A. bremcaulis Dus.). 



As Macloskie has remarked, the name (A. brevicaulis] was already 

 occupied when I described this plant. Its original name should therefore 

 be replaced by A. dusenii Macl. 



It occurs also in S. Patagonia, near Lago Argentine ; W. Patagonia, 

 upper Rio Aysen. D. 



A. MOYANOI Speg. Speg. Prim. Flor. Chile., p. 60 1 (Macl., p. 506). 

 Central Patagonia, along Rio Teka-choique. 



P. 506: A. patagonicus Phil, is regarded by Prof. C. Skottsberg as 

 included in A. rengifoi Phil. (p. 507). It occurs on the pampas by Coy 

 Inlet, Patagonia. 



Having only very incomplete material at my disposal, I am not in a 

 position to give a true version of the species of the present genus. D.
