CHARACTERS OF TRIBES AND GENERA. 91 
Under these circumstances, in my “Enumeration of 
Genera,” in 1841, I deemed it proper to unite Marginaria 
with Goniophlebiwm, and stated that "the peculiarities 
of habit of the species forming this genus admit of 
their being arranged under several sections, which may 
with no great impropriety be considered as genera." And 
now (1875) finding that the species are variously arranged 
by different authors under atleast ten or twelve different 
genera, although on bringing them together according 
to their natural habits, I find I cannot amend my original 
arrangement, I deem it best to rank the sections as genera. 
: In the “Species Filicum," Goniophlebium and Marginaria 
. of Presl, are united and treated as a section of Polypodium 
in which are enumerated twenty-nine species, and in the - 
 * Synopsis," the number is increased to thirty-nine ; but I 
must here observe that in consequence of determining | 
species from herbarium specimens great confusion pervades 
. the synonymy. | 
. The following are examples of the best known species, of ` 
which fifteen have come under my notice in a living state :— 
* Fronds simple. 
G. glaucophyllum (Kze). 
** Fronds pinnatifid. S 
G. Scouleri (Hook et Grev.), Q. pectinatum (J. Sm. Bot. 
Voy. Herald), G. patens (J. Sm. Bot. Voy. Herald), G. tri- 
loba (Cav.), (Synaminia triloba, Presl), G.appendiculatum — 
(Klot.), (v v.), G. plesiosorum (Kze.), G. pubescens (Hook et ` ` 
Grev.), G. surrucuchense (Hook.), G: plectolepis (Hook.), E 
(vv. G. punctulatum (Hook.), G. loriceum (Linn), (v V+)» 
G. latipes (Lang. et Fisch.), G. Catherine (Lang. et Fisch.), 
(vv.) G. glaucum (Radd.), (v v-); G. harpeodes (Link), 
v v.), G. calpodes (Kze.), (v v.), G- letum (Radd.), (v v-)
