Our specimens were gathered by Mr. Menzies in New Zealand; and they seem in every essential 
particular to correspond with Forster's £7. multifidum, as described by Swartz, who observes, that it 
comes near to 77. fucoides, but differs in the form of the frond, in the much narrower laciniz, and 
in the entire valves of the involucre; and that it is distinguished from £. bivalve Vorster, by the 
different situation of the fructification, &c. 
Schkuhr has figured the barren fronds of two Zymenophylla under the name of Z. bivalve and 
H. multifidum: but we must observe, that the structure of the former approaches nearer to our 
plant than the latter. 
To judge from the involucre, this species seems to be intermediate between the genera Hymeno- 
phullum and ZTichomanes ; and we fear there are many in the same predicament.
