96 PATAGONIAN EXPEDITIONS: BOTANY. 



SYMPHYOSTEMON Miers. 

 S. BIFLORUS (Thunb.) Bak. Macl., p. 318. 



Macloskie remarks (Macl., p. 961) that this species should have the 

 name of S. odoratissimus (Lindl.) Miers, but this is not correct. Thun- 

 berg was the first to describe the plant, viz., under the name of gladiolus 

 biflorus. According to the international rules of botanical nomenclature 

 the name of this species should be S. biflorus. 



S. ODORATISSIMUS (Lindl.) Miers and S. patagonicus Speg. 



Macl., p. 319. 



Are to be deleted, both being synonymous with S. biflorus.
