of a fingCF;, and is just eucK as might be expected (by analog}) to be produced from a caudcx similar to 
that of the Chekea plant. I have also been favoured with a note from Dr. G. Keichenbach, jun,, of 
Leipzig, stating that he has compared the pinna? of the Chelsea plant with Kunze's specimen of '' Lomaria 
eriopus,'' and finds them to be identically the same; therefore Lomaria eriopus must be expunged from 
Filices^ for although its venation is analogous to many Ferns, yet its character in every other respect shows 
that it belongs to CijcadacecBj presenting a new feature in that order on account of its simply forked vena- 
tion rinsing from a true midrib, thus rendering untenable the character which is usually relied upon for 
distinguishing fossil CycadetB from fossil Filices ; but before we can with certainty determine the true 
relationship of this singular plant, it is necessary to be furnished with the female cone, which we hope to 
receive before long from Natal*,

Ai.plenium fankulacmm, H. et B., is probably only a slight variation of this species. The gradual 
transition of forms in this extensive and wide-spread genus, renders it impossible to determine with any 
degree of certainty the limits of many of the species originaUy described by Linnaeus, Swartz, and others ; 
and as forms from new localities continue to be added to our collections, the difficulty becomes greater ; 
and is further increased by the circumstance of young plants of large growing species producing fertile 
fronds when not more than an inch or two in height, which, with the intermediate states, have often been 
described as distinct species. 
* Since the above was written, several stems and a male cone, with a few scales of apparently the 
female cone, have been exhibited at a meeting of the Linnean Society by Mr. Thomas Moore, who has, in 
Hooker's Journal of Botany, vol. v. p. 228, given to this plant the name of Stangm-ia paradoxa. More 
recently, plants have been received at the Koyal Gardens, Kew, and further observations published by me 
at p. 88, vol. vi. of the same work.
