Fern-stoves of Kew, from plants received from Mr. Sim, of Foot’s Cray, 
I quite agree with Brackenridge in his observation under 
this plant, namely, that ‘it is an extremely well-marked species, 
of peculiar habit, and of frequent occurrence” (in the tropical 
Pacific islands). Indeed, making a moderate allowance for what 
must be ceded to Ferns in general for certain degrees of varia- 
tion, easily comprehended by the aid of a large series of speci- 
mens, I hardly know one species of Fern, certainly none among 
the genus Ziichomanes, so easily recognized as the present. But 
the above synonyms exhibit a great difference of opinion among 
other botanists, and those botanists who have made Ferns their 
special study, and whose opinions are consequently deserving of 
respect and consideration. The only ones of which I can reason- 
ably express any doubt are the Zzchomanes Zollingeri and Cepha- 
lomanes Madagascartense of Van den Bosch, for I have never 
seen authentic samples; but, the former Kunze does not consider 
distinct from Zr. Javanicum ; and of the latter its author says, 
“habitu et statura convenit cum 7. Zollingert, et curvato, soro- 
rum forma cum C. rhomboideo.” The country, indeed, Mada- 
gascar, is very remote from all the localities yet recorded for 7y. 
Javanicum. Much stress is Jaid by Van den Bosch on the nature 
of the cellules, and the base of the pine is described as cordate. 
It is therefore possibly a distinct species.* 
Presl has created some confusion by his fondness for genus- 
making, in constituting of Mr. Cuming’s specimens, n. 169, from 
Luzon, a new genus, under the name of Cephalomunes, and has 
described and figured a large globose head to the columella, such

‘Nederlandsch Kruidkundig Archief,’ 1861, which contains a Supplement to the 
Synopsis Hymenophyllacearum, by Dr. Van den Bosch, with two additional species 
of Cephalomanes, viz. C. Australicum, var. a, B, from the Isle of Pines, Cuming, 0. 
8 (but Cuming was never there); and C. Wilkesii, Brackenridge’s plant from 
the Fiji Islands. My numerous specimens from Fiji are unquestionably Zr,
