the narrow and more compound it can usually be traced quite to the apex. 

 Fruclijicailon of both kinds is scattered over the surface ; the conceptacles 

 (ceramidia) being solitary, and the sticliidla collected in little tufts. The 

 conceptacles are ovate, shortly stijjitate, with thick, cellular walls, and they 

 contain a tuft of pear-shaped spores. The dichidia are narrow-obovate or 

 spathulate, and contain a few tetraspores, in double or single row. The 

 colour is a deep purplish-red, turning brown in drying. The substance is 

 rather rigidly membranous. The young frond scarcely adheres to paper in 

 drying, and the old one does not adhere. 



This is the original species upon which the genus Lenorman- 

 dia was founded, and by comparing our figure with L. Muelleri 

 (Plate XLV.), it will be seen how nearly that plant is related to 

 this. Except in the more or less valid nerving, a character of 

 but slight importance, the two scarcely differ. Mere ramifica- 

 tion, in an irregularly proliferous frond, cannot be depended on ; 

 and in breadth and outline of the phyllodia, individuals growing 

 side by side vary extremely. Our figure represents an average 

 or typical specimen, but it would have been easy to have selected 

 one Avith much narrower, even linear fronds, or with greatly 

 broader. Some of the broader specimens, indeed, are almost 

 completely destitute of midrib altogether, appearing (at least 

 when dry) deserving of the name enervis. Others again are 

 nearly smooth, others very rough ; some of delicate membranous 

 substance, and some coarse and thick. On the whole, therefore, 

 seeing the variability of L. spedahilis in its one locality, I am 

 disposed to regard L. Muelleri as merely one of its extremely 

 divaricated forms, and perhaps L. Chamnnii (of New Zealand) 

 as another. The Tasmanian L. marginaia, on the contrary, 

 seems to be a well marked species.
