 I have thought it necessary, for the proper illustration 

 of Nitophyllum punctatum to give Beveral figures, showing 

 the principal forms which tins variable plant assumes. 

 8 of these look so distinct that many authors c 



them as separate species, and it is not without having care- 

 fully examined the Bubject, and consulted a very extensive 

 suite of specimens, that 1 have formed an opposite opinion. 



170. Hillise (Miss Hiffl* NitophylUwn) ; frond thickish, but 



tender, veiny toward- the base, of a roundish outline, 



gularly and more or less deeply deft : the segments ob- 

 long, slightly waved, obtuse; spots of granules dot-like, 

 very minute, densely scattered over the Burface of the frond,

 1 have thought it right to restore the specific name 

 under which this line Bpecies lias been described by Dr. 

 Greville, in preference to that i)i' ulvoideum, which I 

 adopted in the * .Manual,' in deference to tin- authority ^( 

 Sir \V. Booker, who, in tie * British Flora,' regards Nito-
