BIBLIOGEAPHICAL NOTES. 359 



A few changes of nomenclature have been rendered necessary, 

 notably in the Sordarietr, a group to which Winter has devoted 

 special attention. He gives great prominence to spore characters 

 combined with the habit of the plant, and, following these lines, he 

 has placed in three well-defined genera all those species that have 

 non-septate spores : Sordaria, Ihjpocopni, and Puduspora. The 

 spores in the first two genera are alike, black or brown, elliptical- 

 shaped spores with a colourless gelatinous wal), but the habit is 

 different : the perithecia of Sordaria grow singly, those of Hypo- 

 copra are combined in a stroma, the only genus in this group that 

 grows in this manner. 



Podospora includes those species in which the dark-coloured 

 spores have one or more colourless gelatinous appendages. Be- 

 litschia and Spororma have variously septate spores, and as this 

 character has been always recognized as of generic importance, no 

 change has beeen made in these genera. 



Following Winter's arrangement for the genera with simple 

 spores — 



Hypocopra stercoraria Sacc. {SphcBria stercoraria Sow.) becomes 

 Sordaria stercoraria A. L. Sm. H. scatiyena Sacc. {Sph. scatiyena 

 B. & Br.) becomes Sordaria scatiyena A. L. Sm. H. vesticola Sacc. 

 [Sph. vesticola B. & Br.) becomes Sordaria vesticola A. L. Sm. 



Sordaria Carhonaria Sacc. {Sph. Carhonaria Plowr.) becomes 

 Podospora carhonaria A. L. Sm. : the brown spores have a persistent 

 small colourless appendage. *S'. caudata Sacc. {Sph. caudata Curr.) 

 becomes Podospora caudata A. L. Sm. S. sparyanicola Bucknall. 

 becomes Podospora sparyanicola A. L. Sm. 



While preparing the Hyphomycetes for exhibition, I found that 

 the name hmqualis, proposed by Cooke & Massee for a species of 

 Oospora, was already occupied by O. incequalis Sacc. & Vogl. (Torula 

 incBqualis Corda). I therefore propose to call this plant 0. Massed.

XIII. — " The Rarest Typographic Product of Linn^us." 



[Heer von Flatt has lately published in the Botanisches Central- 

 blatt (Bd. Ixvi. (1896), 21G-222) an interesting article on two 

 suppressed pages of the first edition of Linnaeus's Species Plantarum, 

 entitled "Das seltenste typographische Product Linne's." The fact 

 was previously known, for a note to that effect was written by Mr. 

 W. Carruthers in the example cited at the end of this note. The 

 special interest attaching to Herr von Flatt's notice is, that he gives 

 facsimile reproductions of the suppressed pages ; he has, however, 

 drawn some erroneous inferences. Tlie following is a shortened 

 translation of his article, to which I have appended a few remarks.

Assuredly many botanists have handled the first edition of the 

 Species Plantarum since its first appearance, but up to the present
