countries and like all such species has been discovered to be "new" on numerous
occasions." A number of these seem to me to be absolutely the same
and I can see no difference whatever on which to base "new species"'"
'
Forms of Hexagona tenuis or related plants.
HEXAGONA PULCHELLA (Fig. 3o 5 ).-This plant from Java seems
exactly the same as the type form except smaller pores.

Hexagona polygramma.
HEXAGONA POLYGRAMMA (Fig. 308). Originally from Cuba, the
type is practically the same as that of tenuis with pores slightly larger. In
most museums, however, all these similar plants are arranged in two covers,
one "Hexagona tenuis, Hooker," the other "Hexagona polygramma, Mont."
I can not believe that the namers have any distinct idea of a difference, for
in both covers I have found indiscriminately collections varying as follows:
Size of spores. From very small, as shown in Fig. 305, to size medium, as
shown in Fig. 307.
Surface. Relatively smooth and evenly zoned, as Fig. 303-, to strongly
rugulose, as shown in Fig. 304.
Color of pileus. Very pale, almost white to brown, and many deep reddish
brown.
23 Not necessarily all, however, that are raked up and tabulated. Thus "Polyporus bivalvis,
Pers.," given as a synonym, has little resemblance to it and is not a Hexagona. A
good specimen is in Persoon's herbarium. "Hexagona exagona cingulata, Lev.," and "He
c
xagona uni-
color, Fries'," are also said to be synonyms, but that is only a ague guess, as no specimens
of either exist, and the compiler knew nothing about them.
