Anthurushas the spore mass against the inner face (and sides) of the 
arms whilst in Lysurus it is not borne against the inner face of the 
arms. According to this definition the plant is an Anthurus. Whether 
“Anthurus borealis” is the same as “Eysurus australiensis” deponent 
sayeth not, but thinks it is probable. 
We present herewith a figure (74) of the English plant from a 
photograph from Carleton Rea and also figure (75) of the American 
plant from a photograph from G. E. Stone. 
277—POLYSACCUM BOUDIERI. 
It was Vittadini, I believe who first advanced the proposition 
that European Polysaccums belong to the same species, although the 
idea has been taken up recently and a formidable, list of synonyms 
compiled. It must be admitted that the “species’’ can only be dis¬ 
tinguished by their general size and shape and that they run into each 
other in a most per¬ 
plexing manner. This 
is true not only of the 
species of Europe but 
of the entire world. It 
is therefore refreshing 
to find a specimen 
that seems to differ 
from other plants not 
only by having a dif¬ 
ferent shape but other 
peculiarities. Polysac- 
cum Boudieri (the only 
specimen known) (see 
fig. 76) is 8 cm. high 
and Sy 2 cm. in diam¬ 
eter. The elongated 
shape is peculiar to 
this species as far as I 
have ever seen speci¬ 
mens, though Nees’ 
figure is same shape. 
Usually Polysaccum 
are globose or depres¬ 
sed globose. The peridium is not like other species, a single friable 
layer but consists of two layers the outer peeling off in the manner of 
a Phellorina somewhat. This feature plainly shown in our figure is 
the most important character to my mind The peridioles are friable 
as in all species but do not crumble as usual. In this plant the walls 
of the peridioles largely consist of hyaline hyphae and in breaking up 
these walls “fray out’’ giving it a cottony appearance. Shreds of 
these hyaline hyphae mixed with the spores under the microscope ap¬ 
pear as though they were short capillitium threads. The spore mass
