Howe: Oropogon loxensis

adopted the middle course and considered Oropogon as a sub- 

 genus. In my Classification de la Famille des Usneaceae I'Amer- 

 ique du Nord, Paris, 1912, I followed the latter author, recogniz- 

 ing Oropogon as a section. After further study of spore charac- 

 ters and their phylogenetic importance (Hue, Bull. Soc. Bot. 

 France 58: 191 1) I am inclined to give to the diverse types of 

 spore septation generic rank, as I did in the first instance and in 

 accord with Dr. Zahlbruckner's view. 



Oropogon loxensis (Fee) Th. Fries 



Type : not indicated ; there is a specimen in the Museum at Paris 

 which was collected by Bonpland and compared with the type 

 by Nylander according to a note on the label, though the loca- 

 tion of the type is not mentioned. Professor Dr. H. Kniep, of 

 the Institut at Strassburg, kindly sent me the specimen here 

 figured, which is taken for the type. The label, however, is 

 the same as those in the Paris Museum collected by Lechler 

 probably in 1854, and not in 1824. The specimen is decidedly 

 atypical, and resembles more closely the boreal Coelocaulon 

 divcrgens as stated below. Fee was a professor at Strassburg, 

 but the type is probably in Brazil, where, however, I have been 

 unable to locate it, although an attempt was made to do so 

 through Dr. Neves Armond, of the Museo Nacional do Rio de 

 Janeiro.
