species was first observed by Banks and Solander, who applied the manuscript name 

 of Leontodon glabratum to it. Hooker associated it with the introduced T. officinale 

 Wigg {T. vulgare Schrank). Kirk, in the "Students' Flora," separated it as a 

 variety, under the name of glabratus, while more recently Dr. Cockayne has given 

 it full specific honours as Taraxacum glabratum. Neither Kirk nor Cockayne appears 

 to have compared our plant with the South American T. magellanicum Comm., which 

 ranges from Chile to Fuegia and the Falkland Islands. Dr. Handel-Mazetti, how- 

 ever, has done this in a very complete manner, and has satisfactorily established the 

 identity of the two plants, which must in future bear the name of T . magellanicum. 

 He points out that T. magellanicum can be readily distinguished from T. vulgare 

 (T. officinale) by the outer bracts of the involucre being broad, conspicuously mar- 

 gined, and always erect and appressed. In T. vulgare the exterior bracts are linear, 

 not margined, and usually reflexed. 



Dr. Handel-Mazetti's monograph must be regarded as an excellent example ol 

 careful and painstaking systematic work, and will probably long remain the standard 

 authority on the genus. T. F. C.
