Pteridophj'ten. 677 



The leaf lamina in M. Alidae is somewhat thicker than in M. 

 Smithii. M. Alidae has obscure pseudo-nerves between the veins. 

 M. Smithii still possesses a true annulus in the sporangium, and 

 the indusium is less developed than in M. Alidae. Jongmans. 



Christensen, C, Filices Purdomianae. (The Botan. Gazette. 

 LVI. p. 331-338. 1913.) 



The paper contains an alphabetical list of the species in the 

 collection of Mr. W. Pur dorn, collected in 1910 in Shensi during 

 the Arnold Arboretum Expedition to northern China and remarks 

 on some species with descriptions of the new forms. 



Remarks on: Adiantum aristatum Christ, A. erythrochlarnys 

 Diels, Cystopteris moupinensis Franch., Dryopteris lacera (Thunb.) 

 O. Ktze., Gymnopteris bipinnata Christ, Polypodiuni clathratuni 

 Clarke, P. eilophyllum Diels. 



New forms: Athyrin^n niongolicum (Franch.) Diels var. Purdo- 

 mii; A. Saygentii, a new species of the group of A. acro stich o'ides 

 (Sw.) Diels, it Stands between A. Giraldii Christ and A. mongoli- 

 cum; Cheilanthes lanceolata , section Aleuritopteris , allied to C. auran- 

 tiaca (Cav.) Moore; Dryopteris Piirdomii, section Lastrea, most like 

 a narrow form of D. brimneo-villosa (Wall.) C. Chr.; D. sericea, 

 section Eudryopteris, a most distinct fern, in its peculiar pubescence 

 unlike all other species of the section, in general habit it resembles 

 D. cristata] Matteuccia intermedia, a most critical form, intermediate 

 between M. struthiopteris (L.) Tod. and M. orientalis (Hook.) Trev. 

 It is possible that it is identical with M. orientalis ^ar. brevis Christ; 

 Polystichum gracilipes, closely related to P. lanceolatum (Bak.) 

 Diels; Woodsia lanosa Hook. var. attenuata, perhaps a new species.
