markably wrinkled appearance. The pores and substance are 

 alike, which are the points on which the greatest stress must 

 be laid when difficulties occur. The pores however, especially 

 in Hexagona, vary much in size, so that even these are not 

 always decisive. This state appears to approach Pol. levissi- 

 mus, Fr. Ep. The colour in these specimens is far brighter.

The plant of Montagne, of which a figure will appear in the 

 history of Cuba, is precisely that of Swartz. It was next to im- 

 possible without inspection of specimens to have ascertained 

 their identity, the name of Swartz being altogether inapplica- 

 ble, as the species is not resupinate. The name could have 

 arisen only from an accidental inversion of the specimens ob- 

 tained, which Swartz informs us were very few.

Ceylon, Konig. Herb. Mus. Brit. 



Imbricated ; pilei 1 — 2 inches broad, f — 1£ inch long, ses- 

 sile, lobed ; lobes roundish or reniform, very hard and rigid, 

 corky, contracted in drying, pruinose, fawn-coloured, with nu- 

 merous rufous, smooth and rather shining furrow-like zones, 

 with many of the interstices raised and forming sharp ridges ; 

 rugulose, in some specimens regularly decussated by minute 

 radiating lines ; edge very thin. Pores extremely minute, in- 

 visible to the naked eye, except a few whose orifices are ob- 

 lique, brownish. 



This species is allied to Pol. microporus, but differs from it 

 in its regularly zoned brightly coloured pileus and in its whole 

 habit. It is perhaps more nearly allied to Polyporus micro- 

 megas, Mont., but the specimens of that species hitherto ob- 

 tained are so few and imperfect as to make it impossible to 

 speak positively ; better specimens may prove them scarcely 

 at all allied. It is a very beautiful species.
