CHILEAN SPECIES OF METZGERIA. 321 



record was based, bears the name M. conjugata j3 violacea and was col- 

 lected at Valdivia. It agrees in all essential respects with a specimen 

 in the Schiffner Herbarium, likewise collected at Valdivia by Hahn 

 and coming originally from the Jack Herbarium. Both specimens are 

 sterile and, although hardly in a condition to be determined, are surely 

 not M. conjugata. Their distinct bluish coloration might seem to 

 indicate M. violacea, but the complete absence of gemmae does not 

 support this idea. The wings of the thallus, moreover, are broader 

 than is usual in M. violacea and their margins are scarcely if at all 

 revolute. A specimen in the herbarium of the New York Botanical 

 Garden, which is said to have been collected in Peru by Lechler, adds 

 to the uncertainty. This specimen is a mixture of M. violacea and a 

 species strongly resembling the Valdivia specimens. The material 

 of this species, however, shows scattered dorsal gemmae on broad 

 thallus-branches and is thus clearly distinct from M. violacea. Unfor- 

 tunately the plants are not only too fragmentary for description but 

 their identity with Halm's specimens, which bear no gemmae, can not 

 be regarded as definitely established. 



The records for M. furcata are the following: Cape Horn, Hooker 

 (see 8, p. 480, as Jungermannia furcata) ; Basket Island, Spegazzini 

 (see 11, p. 257); and Chiloe, Skottsberg (see 19, p. 10). Hooker's 

 material of u J. furcata" in the Mitten Herbarium, representing a part 

 of the original collection, is made up very largely of M. decipiens (see 

 page 296), although a slight admixture of M. decrescens is present (see 

 page 279). Since Lindberg found M. hamata in the same collection 

 (see page 315) it is possible that still other species may have been 

 included. This possibility, however, is rather remote, and it seems 

 justifiable to conclude that Hooker and Taylor's record was wholly 

 based on incorrect determinations. Regarding the Basket Island 

 and Chiloe records the writer can make no statements, since the speci- 

 mens involved have not been available for examination.
