NOTES FOR BOTANISTS. XXI 



Patagonium carnosum Dus., is to be deleted, being identical with P. 



salicornioides (Speg.) Speg. The original description overlooked 



the tubercles of the fruit, and for this reason Dusen concluded that 



he had got a different plant; p. 513. 



Loasa karraikensis vice L. patagonica U. & G. (non Speg.), p. 587. 



See p. 962. 



Ugni ugni (Mol.), vice Myrtus ugni, and vice Ugni molince, p. 602. 

 Nardophyllum nardophyllum (O. Ktze.), vice Aster nardophyllum, 



p. 784. See p. 963. 



Senecio magellanensis (Phil.), vice S. magellanicus Phil., p. 852. 

 Nassauma candollei (DC.), vice Nassauma (Panargyrus] lagascce 



(DC), p. 878. 



Page 379 the name Calandrinia densifolia should be C. densiflora, and 

 in p. 796 Erigeron spinulosus ought to be E. spiculosus. 



Whilst complying with the rule which produces such names as Ugni 

 ugni, I have" never approved of this rule. I think that when a specific 

 name is promoted so as to become generic, then priorities shall, be prop- 

 erly maintained by demoting the previous generic name so as to become 

 specific. Thus I should make the old name Myrtus ugni Mol. become 

 Ugni myrtus (Mol.) ; and Aster nardophyllum O. Ktze. become Nardo- 

 phyllum aster (O. Ktze.). 



Collomia pusilla Dus., p. 670, was based on insufficient material, and 

 on his recent exploration its author, Dr. Dusen, 'found that it is Androsace 

 salad F. Kurtz ; also that it is identical with A. septentrionalis Speg. (non 

 Linn.). He adds "Perhaps A. salad may be identical with A. ocdden- 

 talis Pursh." Through his favor I am able to compare it with A. ocd- 

 dentalis, and I find them to be quite different. 



The beech figured on Plate XIV as the host of Myzodendron, is of the 

 species Nothofagiis pumilio (P. & E.) Blume. On the plate it is errone- 

 ously assigned to N. antarctica, whose leaves are correctly figured on 

 page 327. 



Dr. Dusen calls my attention to the difference between Sprague's 

 description of Hamadryas sempervivoides, p. 414, with laciniae of leaves 

 - glabrous, and its figure in Plate XVI which presents the laciniae as ciliate 

 or hairy. The young specimens recently sent me by Dusen have the 

 laciniae quite glabrous, but older specimens have the leaf-sheath woolly, 

 as stated by Sprague ; and this woolliness invades the laciniae, as a
