144 PATAGONIAN EXPEDITIONS I BOTANY. 



5. D. glandulifera (Speg.) Gilg et Musch.; instead of Sophia glandu- 

 lifera Speg., described p. 448, no. 4, with the distribution. 



6. D. glaucescens (Phil.) Prantl., instead of Sophia glaucescens (Phil), 

 described p. 448, no. 5. 



Chili, Cordillera of Santiago ; Mid-Patagonia, Chubut. 



7. D. subscandens (Speg.) Gilg et Musch., instead of Sisymbrium sub- 

 scandens Speg., described p. 450. no. 9. 



N. Patagonia, near Carmen de Patagones. Similarly D. heterotricha 

 Speg., tenuissima Phil. 



P. 449: Sophia sagittata (Hook. & Am.) should be deleted, being 

 identical with Sisymbrium sagittatum Hook. & Arn., and both synonyms 

 of Thlaspi magellanicum Com., p. 429. 



P. 451 : Alyssum maritimum Linn., "Undoubtedly recently introduced 

 and still undomesticated." P. 452. Bray a; the species are transferred 

 to genus Eudema, except Braya pusilla A. Gray, which must be deleted, 

 as it does not occur in Patagonia. Macloskie's determination (p. 453, 

 no. 5, concerned a specimen of Onuris oligosperma (Speg.) Gilg et 

 Muschler. 



P. 451 : Arabis magellanica (Pers.), in p. 453 sub Hesperis> 

 The former of these seems to be the most convenient name (fide 

 Skottsberg). 



Add Macl., p. 451, Cruciferae before Braya: 



EUDEMA. 



Gilg and Muschler hold that the true Braya does not occur in South 

 America ; but some new Eudemas are there, whose characters tend towards 

 a new group, Brayopsis, like Braya, yet different. 



Eudema is one of the S. American genera. It contains caespitose herbs 

 with small linear or spathulate leaves, subequal spreading sepals, and ses- 

 sile ovary, filiform style and capitate stigma. Silicic ovate-oblong, obtuse, 

 compressed parallel to the fenestrate dissepiment; the valves 5-12 seeded. 



Gilg and Muschler refer to it, or to Brayofisis, or Englerocharis, or 

 Weberhauera, most of the South American species formerly placed in 

 Braya, Sisymbrium and Draba.
