forms ; as we travel westward S. Geiim becomes more prevalent. 

 On the Galtees S. umhrosa alone occurs ; on the Reeks 8. iimbrosa 

 is most abundant ; but S. Geum is frequent, while -S'. hirmta occurs. 

 S. Geum, however, never ascends to any great height on the Reeks, 

 finding its upper limit at 1650 feet in Cumloughra, while S. hirsuta 

 is quite lowland. On the Slieve Mish Mountain, west of Tralee, 

 S. Geum prevails at 2500 feet, and is abundant." 



Two parts of the ' Flora Brasiliensis have recently been issued 

 — a continuation of Mr. Baker's enumeration of the Compositce, 

 containing the Asteroidea and Inuloidem ; and Dr. Kanitz's mono- 

 graph of the Brazilian Haloragem. Mr. Baker raises DeCandolle's 

 section Leucopsis of the genus Aplopappus to the rank of a genus. 



The ' Transactions of the Penzance Natural History and 

 Antiquarian Society for 1881-82 ' contains several papers of 

 botanical interest. Mr. W. Curnow gives a list of the HepaticcB of 

 West Cornwall, and in a postscript mentions his re-discovery of the 

 long-lost Petalophyllum lialfsii in the sand-flats at Gwithian. In 

 conjunction with Mr. John Ralfs, the same author gives a list 

 of West Cornwall Mosses. Mr. Ralfs contributes a paper ' On the 

 genus Euphrasia and its Forms,' of which we may give an abstract 

 in a futm-e number. He recognises and describes four ' forms ' in 

 West Cornwall : — E. mo7itana, Jord. ; E. tetracjuetra, Breb. ; E. 

 gracilis, Fr. ; and E. ericetormn, Jord. 



The last part (July 1882) of the ' Transactions of the Epping 

 Forest and County of Essex Naturalists' Field Club ' contains the 

 conclusion of Mr. Boulger's paper ' On the Origin and Distribution 

 of the British Flora,' and ' A preliminary List of the Hymeno- 

 mycetal Fungi of Ei^ping Forest,' by Dr. Cooke and Mr. English. 

 Although not primarily of botanical interest, the paper on the 

 Galls of Essex, by Mr. E. A. Fitch, is worthy of note. The 

 species are arranged in the first instance in the order of the plants 

 upon which they are found, numerous figures of the affected parts 

 being given. The prominence given to local natural history in 

 these Transactions is worthy of all praise. 



The last instalment of Professor Asa Gray's ' Contributions to 

 North American Botany ' (issued June 26), contains among other 

 interesting matter, " Studies of Aster and Solidayo in the older 

 Herbaria," — the result of the author's visit to Europe last year. 

 He examined the specimens in the herbaria of Linnaeus, Cliffort, 

 Banks, Morison, Sherard, and Willdenow ; the herbarium of Nees 

 von Esenbeck he was unable to trace. A " general disposition 

 of the admitted North American species " of Solidaf/o follows. 

 The second contribution is a description of new plants, chiefly from 

 Arizona and the adjacent districts. These are mostly Composita;, 

 and include three new genera of that order : — Plwnmera ( P. jiori- 

 hunda), discovered by Mr. and Mrs. Lemmon in South Arizona, and 

 dedicated to the latter under her maiden name ; Dugesia (Lind- 

 heimera me.iicana, A. Gray) ; and Hecastocleis [H. Shocklegi), a genus 

 of Mutisiacecc near Ainslidu. 



Pkof. Sekeno Watson has also issued (Aug. 10) a fasci- 

 culus of 'Contributions of American Botany,' containing a 'List
