and often scarcely visible costa, and sprinkled with minute rough points. I 

 have not seen stichidia ; but ceramidia of an ovate form are often scattered 

 over both surfaces of the frond, being developed out of the rough points : 

 they contain a tuft of narrow-pear-shaped spores and paranemata. The 

 surface of the frond, under a pocket-lens, appears decussated with oblique 

 lines, which divide the membrane into lozenge-shaped areola?, indicative of 

 the large, obliquely seriated, rhomboid cells which constitute the central 

 substance of the phyllodia. The surface-cellules are very minute, and in 

 several rows. The colour is a brownish-purple, becoming much browner 

 or even blackish in drying. The substance is firmly membranous ; and the 

 plant shrinks, and but imperfectly adheres to paper in drying. 



It must be allowed that this handsome plant is very closely 

 indeed related to the L. spectabilis of Western Australia, from 

 which it chiefly differs in having a more decidedly caulescent 

 frond, with more strongly ribbed phyllodia. The precise form 

 and comparative length and breadth of the fronds are scarcely 

 characters to be depended upon. I first received specimens in 

 1851, from Br. Cardie, of Geelong, to whom I had proposed to 

 dedicate the species, but in this, as in some other cases, I have 

 been anticipated by my friend Dr. Sonder.
