 States in my herbarium are truly bipinnate, but the [)iunules are less divided than 

 in the more tropical specimens). — Sir James Smith figures and describes this 

 jdant, (and he is the first authority,) with a prolonged, naked, proliferous apex 

 (whence the specific name), with most of the pinnrc or segments linear, entire, 

 the basal ones only broader and lobed. Our figures above quoted agree with this 

 in xU respects save the proliferous or radicant apex, nor do any of our specimens 

 possess this character. Many of them, indeed, have several of the pinnii; more or 

 less lobed, but they have never the broad, regularly pinnatifid piimules character- 

 istic of the norma form of its near ally, A. cicutarium, (our n. 189). Most of our 

 specimens of A. rhizophyllum arc rather pinnatifid than pinnated: but then 

 some gradually pass into the form long described as Aspl. (or Ccenopteris or 

 Darea) myriophyllum. This, Mettenius, I think judiciously, unites with A. rhizo- 

 phyllum, while Moore maintains it as distinct, and unites with it A. divaricatum 

 of Kunze. The var. myriophyllum is, however, in all my numerous specimens, 

 as destitute of the rooting character at the apex, as are all my specimens of true 

 rhizophyllum. My fear is, I n)ay have included some, among my deeply cut 

 varieties, of A. cicutarium, especially those with the dwarfed lower pinnae of the 

 frond : they seem to be almost a connecting link between the two species.
