1044 HEPATIC^ COLLECTED BY MR. T. WHITELEGGE IN N. S. WALES, 



the outer rose scales differeiitly shaped, alternate with the sub- 

 jacent whitish teeth or folds of the real perianth. Mr. Mitten 

 has no idea of this interesting character, but as the scales are to 

 be found in Isotachis Lyallii and Gunniana, I think, things will be 

 there as they are in Is. serruhta, and you will understand what 

 the "roughness on its exterior surface" means; in /. Lyallii it is 

 called " per. minute tuberculatum." The perianth of /. Gunniana 

 is "cylindiicum, crassum, rugosum, aince albidum, diaplianum, 

 minute plicat'itm ;" perhaps after this it answers completely the 

 perianth of Jung, serrulata, and if this is true of other species 

 a more interesting character can be safely affirmed of this 

 genus than Mitten suspects ; I have named you five plants, 

 which show this character in the most distinct manner ; Is. 

 muUiceps does it less, but I found them too. This will be a little 

 addition for your paper on New Zealand Hepaticse."
