( 32 ) 
are entirely for a Dipiazium, and the "following is Beddome’s note after the 
description of 11 t. 294. “This species has been included by Sir W. Hooker 
in his Species Filicnm under Athyrium australe, Brack, (which is united with 
umbrosum, J . Smith, by Mr. Baker ;) it however has a quite different involucre to j 
the South Indian species figured under that name at pi. 158 of the ferns of 
Southern India, and it is more flaccid and delicate, and is tripinnate, (subqua- j 
dripinnate) with the nltimate segments subentire, whereas A. australe is tripinnate 
(aubtripinnate) with ultimate pinnules much toothed, these latter differences , 
however are not always constant, or much to be depended upon as a specific 
difference in large compound ferns of # this sort, as young or even small grown 
specimens may be bipinnate, when larger specimens of the same species are 
tripinnate” — Again in the last No. of Bed. 11., in “ l\otes on the Nomencla- 
ture.” He says that, “ Dipiazium assimile, and D. Jerdoni, are also both con- j 
sidered as forms only of 1). polypodioides.” 
My Queensland specimen, marked Athyrium australe, is a true Athyrium ■' 
and quite different, as far as I can see,- from Bed. 1. t. 158, under this name 
and 11. t. 294. Our Ceylon Fern is so distinct in all respects from any 
specimen of Athyrium, or form of Dipiazium polypodioides, that I 
have no hesitation in stating my belief that it is a distinct and well 
marked species, which cannot be confounded with an Athyrium, nor with 
any of our Diplaziums. I suspect that the name on the C. P. 1347 is a 
mistake, but whether it is the tiue A. (D.) assimile of Endlicher is a question 
which 1 have no means of deciding. This fern is found sparingly in Kalibokka 
and Hewahetta, and in abundance in Maturatta, and above the Agras, &c., be- 
low theBopats. 
98. Aspleniura (Dipiazium) lauceum, Thunb. 
Bed. 1. t. 227, and 11. t. 289. Beddome figures and describes the latter 
as D. subserratum, Bl., and gives Penang and Java as its habitat, but I have 
Ceylon specimens to agree with both figures. This is a well marked species, 
found in great abundance in < amp ground in the Forest below Maousakele, 
Kalibokka, and Dimbula. 
99. Asphlenium (Dipiazium) Zeylanicum, Hk. 
Bed. 1. t. 228. Found together with the preceding species often on the 
rich banks of streams. A well marked Fern. 
. 100. Aspltnium (Dipiazium) sylvaticum, Presl. 
Bed 1. t. 161. and 11. t. 243. In his ample note on the habitat of this 
tern, Baker remarks “Of forms included here differing slightly from the 
type, the Malayan. A, Prescottiamim, Wall. (Bed. 11. t. 243) has the 
pinnae rather more deeply lobed towards the base in the lower part of the 
frond • the Ceylonese A. datum, Mett. (C. P. 1849), and a similar plant from 
the Sandwich Islands and Borneo, have them lobed throughout to a depth of 
quarter inch ; the lobes subangular and toothed.”— I find C. P. 1349 attached to the 
most common , and less loped form of our Ceylon fern, and in fact Thwaites 
has not two C P. Nos. for it, showing that he looks upon the two forms as 
one No. Bed. 1. t. 161. is evidently for a very small or very young plant. 
Cultivated m Colombo or as seen in the forests of the interior, the common 
narrow and less lobed form can be seen running into the other, and the lobed 
one into A. (D.) latifolium, Don. In fact a small plant of 100 grown by me 
m Colombo produced one bipinnated frond like one of 105, and here again we 
have a simply pinnated fern running off into a bipinnated one. Why these two 
supposed species are separated by no less than 32 species in the Syn Fil and 
some of them differing widely, I do not understand. In numbering this list 
I have followed the order of the Syn. Fil., otherwise A. (D.) latifolium should 
have been 102 instead of 105.— After I had written this note I noticed the following 
by Bed. after description of his 1. t. 162: This and the last species, D Sylva- 
tieum, are both very variable, and it is doubtful if the two are really 
distinct).” J
