scarious base of the stem of the preceding year ; petiole of the 

 sterile lamina 9-12 cm. (in younger plants not exceeding 3.5 cm.) ; 

 sterile lamina 23 cm. or less wide, the central portion 14 cm. or 

 less high, this and the lateral portions twice pinnate; pinnae 

 broadly lanceolate, 3-6 cm. long, thin, the lowest again pinnate,

Japan, "In silvis prope urbem Tokyo, frequens," J. Matsu- 

 mura; Shimogamo, Kyoto, October 1893, "not common," Ta-

appear in the Berlin herbarium. • 



This is the Japanese plant that Baker refers to B. dancifoliiim 

 and is the one mentioned as B. dancifoliiim in Franchet and 

 Savatier's Enumeratio* as shown by Franchet's own plants 

 in the Paris herbarium. It is more or less common in collec- 

 tions from Japan and has been indiscriminately taken for B. 

 tematum and B. daitcifolium. While it has nothing closely in 

 common with the former, it differs from the latter in its more del- 

 icate texture, and widely in the cutting of its sterile lamina. It is

a very clearly marked species. Its common name in Japan is said 



to be " hanawarabi." 



The ternate species of Botrychium as thus outlined have a 

 distribution covering all the continents except Africa; the de- 

 scribed species are distributed as follows : 



Europe (1) : B. matricariae. 



Asia (3) : Japan— B. tematum, B. Japonicum ; China— ft ter- 

 natum ; India — B. dancifoliiim, B. tematum. 



Australasia (4): Hawaii— A subbifoliatum ; New Zealanc 

 B. australe, B. biforme ; Australia— £. australe ; Tasmania— £. 

 australe ; Samoa— B. daucifolium ; Java— ft daucifolium var. (?)
