History. This plant was described under this name hy Berkeley from 

 the Philippines, and seems to occur mostly in Australia and the Pacific Islands. 

 I found it in Samoa, but it is not common there. In Samoa it usually took 

 the hexagonal form, rarely the lenzitoid form, but in other localitites it may 

 run more often to lenzitoid forms. It is the same plant, I believe, as Daedalea 

 inconcinna, also from the Philippines, and Daedalea intermedia from Australia. 

 I think Hexagona Cesatii from Borneo is exactly the same thing, with a tendency 

 to become a little cyclomycoid. When the history of these polymorphic plants 

 is worked out it will probably be found to have names in other genera such 

 as Lenzites.

 Hexagona macrotrema. Type at Leideti. 



HEXAGONA MACROTREMA (Fig. 315). The description of Hexagona 

 albida covers this species also, for it is the same thing excepting that the sur- 

 face is distinctly pubescent. However, they arc undoubtedly forms of the same 

 species and they occur over the same region (Pacific Islands). 



Hexagona macrotrema was first collected by Junghuhn in Java and so 

 named by him on the label. The specimen is to-day found in Leiden in good 

 condition and bears only Junghuhn's original label. Before he published it, 

 however, Leveille visited the museum, saw the specimen, changed its name, 

 and published it as Hexagona Molkenboeri. This did not please Junghuhn 

 (naturally) and he wrote to Fries, who, when he published it used Junghuhn' S 

 name. 28 The name Molkenboeri is therefore "prior" from an Otto Kuntze 

 point of view, and while I have great regard for priority it does not appeal 

 to me when served with so much rascality. Therefore I use the name macro- 

 trema. 



Hexagona macrotrema is rather rare in the museums and has been mostly 

 named albida. I have seen only the following three specimens: Java (Leiden), 



28 The plant is found in Saccardo, vol. 6, p. 369, under both names, pretending to be 

 two different species, although both names were based on exactly the same specimen.
