XX11 NOTES FOR BOTANISTS. 



tomentum, which was overlooked by Sprague. The hairiness of the plate 

 is the artist's interpretation of this webby tomentum. 



Plate XV. The right name of the plant figured is Escallonia mrgata 

 Pers. (of Saxifragaceae, p. 464). The note on p. 419, line 3, and the 

 perigyny shown by the figure dispose of the trial-name, Berberis mrgata, 

 which escaped notice until Dr. Dusen sent me the correct name. He 

 also informs me that the Hatcher specimen called Berberis ruscifolia (p. 

 418) is B. ilicifolia, that the Patagonium mucronatum (p. 517) is P. 

 lotoides, and that the specimen called Verbena tridactyloides (p. 690) is 

 Euphrasia antarctica (p. 727), of which I have also got other Hatcherian 

 specimens. He displaces some of the specific names as being only 

 synonyms, viz. : Senecio kurtzii is S. kingii (a radiate form of the latter) ; 

 Senecio vagina/oHus is S. argenteus ; and in the same line Senhor Teo- 

 doro Stuckert, of Cordoba, makes Baccharis dusenii (p. 804) a synonym 

 of B. melanopotamica. I respectfully invite further corrections from bot- 

 anists, with a view to using them some day for a supplemental Bulletin. 



III. NEW GENERIC NAMES. 



As some new genera erected by Spegazzini, and one by Hoffmann, 

 have not yet got into the textbooks their descriptions are given in full. 

 Of Spegazzini's genera we have : 



Halophytum (Chenopodiaceae), p. 371. 

 Amarantellus (Amarantaceae), p. 374. 

 Philippiella (Caryophyllacese), p. 397. 

 Delpinoella (Cruciferae), p. 427. 

 Aonikena (Euphorbiacese), p. 555. 

 Monopyrena (Verbenaceas), p. 692. 

 Benthamiella (Solanaceae), p. 712. 

 Strongylomopsis (Compositae), p. 886. 

 Ameghinoa (Compositae), p. 886. 



Hoffmann's new genus of Patagonian plants is Dusenia (Compositae), 

 p. 866, with fig. 105. 



Recent revisions of generic names have caused extensive changes in the 

 complexion of the names of plants, as presented by the Second Supple- 

 ment of the Index Kewensis, and other works. When the revision involves 

 a change of gender of the generic name, as with Luzula becoming Jun- 

 coides, Adesmia becoming Patagonium, and Dava^^a becoming Schinus, 

 terminal changes of the specific names usually, but not always follow suit.
