carps) and Nitophyllum (formation of veins etc), but is not, strictly spöken, interme- 

 diate between them. 



Fortunately, the identity of Agardh' s D. phyllophora and my Pseudophycodrys 

 is well established. Herb. Agardh contains three specimens. No. 31275 (s. n. D. quer- 

 cifolia, named by Hooker) bears Agardh's remark: »an potius D. phyllophora? » It 

 presents the typical features of Pseudophycodrys (Kylin in letter to the writer). No. 



31276, Falkl. 1842, Hooker, is a good female specimen, with cystocarps scattered över 

 the frond, generally on or near the veins. The anatomical structure is typical. No. 



31277, Falkl. Capt. Abbott 1859, was brought to D. crassinervia (by Harvey?). Agardh 

 named it D. phyllophora. Habitually it differs from the rest in the numerous prolifera- 

 tions from the old, denudate costa, but the structure of the apex and midrib leaves 

 little doubt that it is the same thing. 



Cotton, Crypt. Falkl. p. 183 says there are two or three plants at Kew, labelled 

 D. crassinervia but referable to D. phyllophora. Two of these were sent to me for com- 

 parison: neither of them was collected by Hooker (contrary to Agardh no. 31276), nor 

 do they belong to phyllophora. One labelled »Berkele}^ Sound Aug. 1842, Lyall, D. 

 crassinervia p », must, I think, be the same as a specimen in Brit. Mus. mentioned above 

 under D. macloviana, but the old lamina is broader than in any of my plants. The other, 

 also called D. crassinervia p and labelled »Cape Horn sept. 1842 Capt. Crozier», differs 

 from all others. As there are no young growing points and the anatomy of the costa 

 cannot be made out without damaging the specimen, I do not know what it is, but the 

 lamina presents a most conspicuous network of very long cells, forming microscopic 

 veins as in certain Nitophylla of the Cryptoneura-gro\x\), but quite unlike the veins in 

 Apoglossum or in D. macloviana. The specimen consists of two stipitate, narrow oblong 

 (10 x 1 — 1,5 cm) fronds from a common holdfast, with obscure opposite nerves, lined 

 by tetrasporic sori. There are a few large proliferations from the stipe and costa.
