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. 3 o 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 bi- 

 valvis, Pers.," given as a synonym, has little resemblance to it and is not a Hexagona. A 

 good specimen is in Persoon's herbarium. "Hexagona cingulata, Lev.," and "He 



exagona c 



color, Fries'," are also said to be synonyms, but that is only a 

 of either exist, and the compiler knew nothing about them.
