CATALOXTAN MIOEOMYCETES 29 



finding near Barcelona of the Tripolltan species, Puccinia mediter- 

 ranea Trotter, on Polypofjon 7>wnspeliensis, this being the first time 

 it has been seen in Europe; the other record, also from near Barcelona, 

 is of Puccinia Cardui-iJifcnocejjhali, which has hitherto been found 

 only in France, Italy, and the south of Britain. 



Certain genera, such as Perono^pora, Phomopsis, Sepforia, and 

 Pamidaria, seem to have been well looked for, but jthe inadequac}^ of 

 the present knowledge of others is shown by the fact that only one 

 species is recorded for Diaporthe, one for Peziza (with only four 

 other Discomycetes), one for Cytospora, one for ILeiulersonia, one 

 for Gloeosporium, and none for Nectria, Hypoxylon, Diatrype, 

 Dotliidea^ Mvcor, etc., etc. 



The publication is of value, nevertheless, because of the careful 

 treatment of the matter, although in the present scarcity of paper it 

 seems wasteful to devote so much to what might easil^^ have been 

 contained in a smaller volume. The author's frequent eccentricities 

 (»f Latin spelling, also, somewhat mar the satisfaction that could 

 otherwise be derived from a perusal of the work.

BOOK-NOTES, NEWS, etc. 



At the meeting of the Linnean Society on November 15th, 1917, 

 Dr. D. H. Scott, F.R.S., F.L.S., gave an exposition of his paper, 

 "Notes on Cahnnopifys linger," illustrating his remarks by a series 

 of lantern-slides and a large specimen of O. ame'ricana Jeff. & Scott 

 from Kentucky. He stated that Calamopiti/s is a genus of fossil 

 plants, with structure preserved, of Lower Carboniferous age; some 

 species may perliaps go back to the Upper Devonian. The pith, 

 which in certain species contains iiiedullary tracheides, is surrounded 

 by a ring of mesarch xylem-strands. Tlie leaf-trace divides into two 

 as it passes out, and repeated divisions give the petiole, where it is 

 known, the polydesmic structure of Kalymma. The tracheides of the 

 metaxylem and secondary wood have multiseriate bordered pits. 

 Two species, included by the author in Calamojjifys, have been sepa- 

 rated by Zalessky under the generic name Erist'opliyfon. The first 

 ])art of the paper deals with the origin and division of the leaf -trace in 

 C. americana. The relations of the five known species among them- 

 selves, and of the genus as a whole, are then considered. In C. annv- 

 Jaris (from Thuringia) the zone of ]H-Imary xylem is almost, if not 

 quite, continuous. The primary xylem-.strands are eccentrically 

 mesarch, the protoxylem lying towai-ds tlie outer side. There is 

 evidence for the presence of scattered tracheides in the pith, rendering 

 the structure essentially i)rotostelic. Each leaf-traco strand, on its 

 exit from the wood, has its own zone of secondary xylem. In all 

 these respects C. annularis agrees with Cf. anwricana, tlie Kentucky 

 species. In C. Safarni (from Thuringia), on the other hand, the 

 ])rimary xylem-strands are completely isolated and centrally mesarch ; 

 medullary tracheides. appear to be absent. In this species the leaf- 

 trace only divides when outside the zone of secondary wood, while in 

 C. americana tlie divisiun is completed earlier. All these three
