perhaps collected under No. 1602 two allied but différent plants, so that 

 Kiinze and Mettenius may hâve examined and described différent spécimens. 



It happens to be that spécimens in the Buitenzorg Herbarrium from 

 Java, Sumatra, Bornéo and the Philippines, whicli were collected, named 

 and described by Raciborski as A. intcrniedinni Bl. (Flor. Btz , I, 176) or 

 which were received under the namc oi A.intermcdium BLox D.sarawaken- 

 sis V. A.v. R.'dgree more with the description of A. vile given by Mettenius 

 and less with that of Kuiize whilst spécimens collected and described by 

 Raciborski (1. c. , 177) as A. pulvinulifernm Bedd., a species which, 

 according to Christensen's index Filicuni, occurs in Sikkim but not in /aya, 

 if not eiitirely, at least for the greater part of the above cited différences, 

 answers more to the description of Kunze and less to that of Mettenius. 



To my opinion the two species are certainly allied aithough Raciborski 

 emits a différent opinion at the foot of his description of A. vile Kze 

 (1. c , 173). If Raciborski meant to say that the plant which he took for 

 A. vile Kze is not allied with A. intcrnudium Bl. and should not be 

 confused with it he is quite right for his A. vile is neither that of Kunze 

 nor that of Mettenius. 



Resuming the above mentioned arguments I arrive after comparison of 

 the spécimens I hâve at my disposai to the following conclusion. Whether 

 it is correct or not, future will hâve to show, 



1. Aspidium vile Mctt. (not Kze) = A. intermedium Bl. = Lastrea 

 intermedia Bedd., Handb. Ferns Br. I., Supplem., 61 (exclud. syn. and var.) 

 = Dryopteris sarawakensis v. A. v. R. = D. intermedia O. Ktze. — Regarding 

 the spécifie name I observe that Blume's „intermedium" is not the oldest 

 name. There are 3 older plants named Aspidium intermedium, which, 

 however, hâve been reduced to species with still older valid names of 

 which even 2 beloiig to other gênera, so that in „Aspidium" Blume's name 

 „intermedium" has practically become the oldest and therefore 1 deem it 

 unnecessary to replace te name Dryopteris intermedia O. A'^ze by a younger 

 synonym even when the species should be united with D. vilis O. Ktze, 



2. Aspidium vile Kze (not Mett.) = A. pulvinuliferum Rac. (not Bedd.) 

 = Lastrea intermedia Bedd. var. Blumei, Bedd., 1. c. = Lastrea Blumei, 

 Moore p. p. = Dryopteris sarawakensis v. A. v. R. var. Blumei v. A, v.R. 

 (MS.) = D. pulvinuli/era, v.A.v.R. (not O. Ktze) = D. vilis O Ktze. 



3. Aspidium vile Rac. (not Kze, nor Mett.) is a coriaceous xerophilous 

 form of Dryopteris setigera O. Ktze and A. setigerum Ràc. (not Kuhn) = 

 D. setigera O. Ktze var. pallida v. A. v. R. 



Dryopteris Mannii (Hope), v.A.v.R. ; Lastrea intermedia, Bedd., 

 Handb. Ferns Br. I., Supplem., 61, p.p.; Nephrodium Mannii, Hope, in 

 Journ. of Bot., XXVUl, 145. 



The Buitenzorg Herbarium possesses of this British Indian fern a single 

 spécimen received under the name Lastrea Mannii Hope. Beddome reduced 

 it to Lastrea intermedia Bedd. from which it differs by its aspect and in 

 having the indusium similar to that of D. vilis O. Ktze. The veins are
