Annotations. 



(1) Balantiopsis diplopiiylla. — This plant is said to have been 

 found also in Peru, from where it is reported under the name of 

 JPtilidium cancellatum, Nees, in Synopsis Hepat. p. 252. I have 

 examined the original specimen, which is identical with New- 

 Zealand and Australian specimens ; it is very improbable that 

 this plant should have been found on the mountains of Peru, and 

 I suspect some mistake in the name of the country. Both names 

 having been given in 1844, the right of priority depends upon a 

 difference of months only, which I am unable to find out, and 

 if found w r ould not induce me to change Taylor's name. 



(2) Pbtjllania pycn antua. — There have been two forms sent 

 of very different appearance, the normal one growing in places 

 exposed to sunlight, stout and tough, very dark, in a dry state 

 almost black and horny, lobules well developed and hooked, large. 

 A common variety of it is the original specimen of Taylor, flaccid, 

 quite green, lobules small, growing in dark forests. The perianths 

 aid floral leaves of both forms do not show any differences. 



The same may be said also of Frullania squarrosula, and, 

 mutatis mutandis, of all Frullania \ the leaf-lobule (auricle) is 

 folded in if the plants grow in dry atmosphere, and is unrolled 

 or reduced in size and form if they grow in wet and misty 

 localities. This may be observed also in our European species. 

 The leaf-lobule is a water-sac, which is well developed in dry 

 localities, and becomes useless in a damp atmosphere.
