27. Asplenium dareodies Desv. 181 1. A. niagellaiiicuni Kaulf. 1824; C. 

 Chr. & Skottsb. 1.24. One of these unwelcome name-changes, the species, a 

 common fern of south Chile and Fuegia, having been known under the younger 

 name for more than one hundred years, when Weatherby dug up the older 

 name, which had never been used. 



28. Blechnum auriculatum Cav. C. Chr. & Skottsb. 1.25. 



After a renewed examination of the large material in Herb. Stockholm I 

 find it impossible to segregate any good varieties; comp. LOOSER 9. With regard 

 to reiiiotuDi, we pointed out this 1. c, and neither has parvtihon, mentioned as 

 "forma parvula", an\- taxonomic standing. I have not seen specimens of i). /r/- 

 buliiDi Presl (var. Inbuluui Capurroj. 



29. Blechnum valdiviense C. Chr.; C. Chr. & Skottsb. 1.26. B.blechnoides 

 (Bory) Keyserling; L()OSER 9. 54. 



A troublesome case of nomenclature. The oldest name is Loiiiana hlecJnioides 

 Bory 1828 (Chile, Concepcion), but this combination is antedated by L. bleclnioides 

 Desv. 1827, quite another species, doubtfully indentified with B. auricnlahun by 

 Christensen. In 1873, Kevserlixg made the new combination Blec/aiuin blech- 

 noides (Bory) Keyserl., but this name should not be applied to Bory's plant which, 

 as testified by Looser 1. c, is very different from the plant Keyserling had before 

 him; I have not seen Keyserling's paper, of which there doesn't seem to be a copy 

 in any Scandinavian library. If, according to the Rules, B. blcchnoides Keyserl. is the 

 valid name for L. bleclnioides Bory, there is something wrong with these rules. To 

 make the case more interesting, there is another B. blechnoides (Lag. ex. Sw.) C. Chr., 

 based on AspleJiium blechnoides Lag. ex. Sw. 1806. Swartz, in 1810, called it B. 

 U7iilaterale, but Christensen, regardless of the fact that the combination B. blech- 

 noides already existed, used it for LagaSCA's Asplenium and called Bory's Lomaria 

 B. valdiviense. Would it not be possible to convince those who forced these rules 

 upon us that Blechnnvi blechnoides is a splendid example of a confusing name.' 



Looser regards the Juan Fernandez plant as an endemic variety, var. 

 fernmideziajiuDi, stated to be more delicate than the continental form and to 

 have a poorly de\eloped endlobe. This may be true in some instances, but 

 some of my specimens are so like coast forms that 1 find it difficult or im- 

 possible to separate them.
