tion that a specimen had flowered with him and was still 

 alive a year later. The only other records of its flower- 

 ing, respectively on the Riviera 16 and in New South 

 Wales, 17 make no mention of this habit of surviving the 

 flowering period; and it is possible that some other 

 species was referred to by M. Ellemeet. That the seed- 

 lings at Bull's nurseries were very unlike was noted by 

 Moore; 18 and as early as 1869-70 Bull advertised, with 

 fair characterization, in addition to his typical See- 

 manni the varieties acuta, papillosa and parvispina. In 

 the list of his own plants published in 1878, Peacock also 

 mentions a variety rotundifolia of A. Seemannii as he 

 calls it. 



As has been stated above, A. Seemanniana seems to 

 have Segovia, Nicaragua as its type locality, and so is to 

 be sought in the mountains between this locality and the 

 Motagua valley in Guatemala.
