Wliili- rrl'rrriii!_ r t> tin- .Miiitlicrii species of Desmarfstia, it may IHJ worth while to 

 point out a slight error in the key ! tin- aperies which Reinsch publishes in Flora, 1888, 

 pp. 189, 190. He ckHMl D. chordnli* with D. virnlin n having its ultimate pinnules 

 uneortiented. He had apparently never seen D. chordtiliti, and he mimnterpreU'd 

 Harvey's "apice longe nudis" (Flor. Antarct Part II., p, 467) as meaning uncorticated, 

 whereas it simply means unarmed with spinules. We would point out that in D. 

 luirrryniut the axial livphru are corticated to the very tips of the ultimate ramiili 

 (fig. 12).
