NEW PLiBLICATIONS. 87 



eighty remain, forming pnrt of the "Atlantic element" of Dr. Hooker;* 

 about thirty-six only, however, are common to the Azores and the 

 Madeira and Canaries groups, and from this short list probably a quarter 

 must be subtracted for various reasons ; yet Madeira is but five hundred 

 miles distant. The relationship with America is singularly slight, four 

 species only of those which are neither European nor Madeiran being 

 common to that continent and the Azores. The widely spread African 

 shrub Myrsiue ofrlcana alone (of the same list) represents the flora of the 

 much nearer continent of Africa, which is only what might be expected 

 when we remember bow small an African element is found, even in the 

 Canarian flora. 



The remai'kable fact remains, that forty species (one-twelfth of the whole 

 flora) are peculiar to the islands. A list of tiiese will be of value to our 

 readers : — Cardamiue Caldeiranum, Nasturtium Jlexnosum, Cerustinm azo- 

 riciim, Hypericum follosum, Vicia Dennesiana, Rubiis Hochstettorum, Sa- 

 nicula azorica, Animi Hnittii, PetroseUnum trifuliatani, P. Seitbertiunnm, 

 Solidago azorica, Senbertia azorica, Senecio rnalcafulius, Tulpis nobilis, 

 3H.croderis rirjens, M. Jilii, Campanula Fidalll, Vacciniam cylliidraceum., 

 Erica azorica, Erythrcea Massoui, Veronica Dabneyl, Euphrasia gratidi- 

 jiora, Myosotls azorica, M. inarltlma, LysimacJiia azorica. Euphorbia 

 azorica, Habenaria mlcrantha, II. lonytbracteata, Luzula purpureo-splen- 

 dens, Cai-ex azorica, C. IcEvicaulls, C. rujidlfulia, C Hochsletttrluna, C. 

 jioreslana, C. Vulcani, ? Deyeuxia ceespitosa, ? D. azorica, Holcus rlyidus, 

 Festuca petrcea, Isoetes azorica. It will be observed that, with the excep- 

 tion of Seubertla and Microderis, all the genera are European. As above 

 hinted, this list is likely to be somewhat reduced by a more systematic ex- 

 amination of the plants of Portugal. As, however, Mr. Watson, who has 

 had many of these specially Azorean plants under cultivation, finds them 

 to recjuire a damp, equable climate, such as is found in their native 

 islands, and to be quite unfitted to endure a Continental one, we can only 

 expect the more robust species as the Carlces and grasses to be found in 

 Europe. A useful table is added to the catalogue, showing the distribu- 

 tion (approximately) of the Azorean plants through Europe, Madeira, 

 Canaries, Africa, and less completely America. It would have been in- 

 teresting to have traced, as far as is possible, each species through the 

 nine ishmds composing the Azorean group. 



Mr. ^Yatson has defined elsewhere some half-dozen of the novelties of 

 the ishmds, and in the volume before us he fully describes Flcla Dtai- 

 neslaita, found by Mr. Hunt, in St. Michael's, a remarkable plant, with 

 large flowers, which change colour during their expansion. Tlie Spergularla 

 of the Isles, which tlie autlior is niucli inclined to describe as a new species, 

 has been already distinguished by Kindberg in his 'Monograph of, the 

 genus Lepujanuvi' (p. 30 and f. 15) as Z. uzorlcum. 



In the list of Muscl and Ihpatlcae, Mr. Mitten has not confined himself 

 to the Azores, but included the other Atlantic isles, Madeira and the 

 Canaries. His catalogue of Mosses amounts to 151, only forty-seven of 

 which have been met with in the Azores ; Bartramla azorica seems to be 

 the oidy species peculiar to these islands. Of Ihpatlcce, sixty-eight 

 species are known to occur in the Atlantic islands ; of these nineteen are 

 enumerated as Azorean, and two Gymnomil rlum erythrorhlzum and liha- 

 cotheca azorica, are supposed to be peculiar to that flora. Mr. Milieu lias
