Introduction. 
In 1902, LlNDROTH (i) in his admirable monograph made a critical 
study and a thorough revision of the species of Puccinia parasitic on the 
Umbelliferae, which had been left in a chaotic state up to that time. He 
has split up many of the old species, such as Puccinia bullata, P. Pim- 
pinellcz , etc. into numerous new species. He has divided them into five 
groups, by the character of the markings on the epispore and by the thick- 
ness of the wall of teleutospores. He has also laid great stress on the 
position and number of the germ-pores of the uredospores as well as the 
teleutospores as a distinguishing character of the related species. He has 
distinguished seventy nine species of Puccinia as growing on the Umbelliferae 
from different parts of the world. 
In P. and H. SYDOW’S Monographia Uredinearum, the species of Puccinia 
on the Umbelliferae increased to the number of one hundred and twelve. 
Among them, only five species arc attributed to our flora. They are P. 
Cicutce Lasch, P. Nanbuana P. Henn., P. Apii Desm., P. tokyensis Syd., 
and P. angelicicola P. Henn. These are the result of study by Diet EL 
(2, 3), P. Hennings (i, 3, 4) and Sydows (i, 2) on the materials collected 
by SrilRAl, KUSANO, and Nambu. P. A ngelicce of P. HENNINGS (2) on A ngc- 
lica hakonensis and on A ngelica shikokiana (as A . incequalis) is now found 
to contain two new distinct species; and P. bullata of Dietel (i) on 
P eucedanum decursivum, though at first also considered as that species by 
P. Hennings (i) with some doubt, was afterward elevated to a new species 
under the name of P. Nanbuana by the latter authority. P'ive of them arc
