(Xcs, 31, 3G.) A storilo form with the leaves strono-ly fulcatr-, giving tlic 

 plant a very diffci^ent appearance from <hat figured by Brotlierus. I find, 

 liowever^ stems of the falcate-leaved form In original specimens at Kcm^ 

 while a few of the sterns here have the leaves quite straiglit. 



AcANTHOCLADiUM PENNATrRi, Fleisclu in Hedwig. 1. (1911) 281. 



(No. 42.) Of the original plant, collected by von Hoenier in Dutch New 

 Guinea, only a single sterile stem was found, and it is interesting to have its 

 distribution widened by Mr. Clark's specimen. ^ Here, too, only a few frag- 

 mentary stems were found, but quite sufficient to leave little doubt of its 

 identity with this fine species. There is only one discrepancyj a slight one, 

 with Fleischer's description. He describes the cells as '* minutissimo indis- 



tincte seriatim papillosis,'^ a character which, it may be reniarked, does not 

 occur in any other species of the genus — or^ indeeil, in any of the genera of 

 the sub-order Stereodonterc. I have not detected it in Mr. Clnrk's j)lantj or 

 very doubl.Fully, the papillae only occurring very sporadically, and then 

 usually singly.
