The road frequently leads through copses of cork-trees and pines, 

 and large barren tracts are seen covered with Chamccrops humilis. 

 Narcissus serotinus, L., Scilla autumnalis, L., Leucojum autumnale, 

 Squilla maritima, Ranunculus bullatus and Melissa Calamintha flowered 

 everywhere in this lowland ; more rarely Merendera Bulbocodium 

 and Mandragora officinarum. The most interesting plant which pre- 

 sented itself on this road was the Pancratium humile, Cav., or Ca- 

 renoa lutea, Boiss., still so seldom found in herbariums, which hitherto 

 was only known in one locality at Seville, where it occurs rarely, 

 and in another at the Puerto de St. Maria. This lovely and sweet- 

 smelling plant grows luxuriantly and very frequent in the plains 

 of the province of Huelva, where I have observed it from Cartaya to 

 within a few leagues of Seville, and is on some spots, as for example 

 in the environs of the village of Niebla, extremely common. 



The environs of Seville present at this season scarcely anything 

 beside the common autumnal flora of the plains of Lower Andalusia. 



BIBLIOGRAPHICAL NOTICES. 



Phycologia Britannica : or a History of British Sea-weeds, containing 

 Coloured Figures, Generic and Specific Characters, Synonymes, and 

 Descriptions of all the species of Algce inhabiting the Shores- of the 

 British Islands. By William Henky Harvey, M.D., M.R.I.A., 

 Keeper of the Herbarium of the University of Dublin. 



As great admirers of that beautiful portion of our flora, the subjects 

 of which, even more than those of the land, are " born to blush un- 

 seen," we hail with extreme pleasure an illustrated * History of 

 British Sea- weeds.' And above all — on account of the accuracy it 

 insures — one, in which every species inhabiting the shores of the 

 British Islands will be drawn, lithographed and described by the 

 same hand. The importance of this combination in the one indivi- 

 dual is well known to all naturalists who have had any experience ; 

 the species being generally described by one party, drawn by a se- 

 cond, and engraved by a third : — and truly may we say, that " small 

 by degrees and beautifully less" in accuracy is sure to be their fate 

 the more hands they pass through. 



This work is published in royal octavo, to admit of as many spe- 

 cies as possible being figured of full natural size ; when this cannot 

 be done, a double plate will occasionally appear ; and of the giants 

 of the deep, a portion will be given of natural size ; when the spe- 

 cies are minute, two will be represented on the same plate, as we 

 already see done in the Elachistea, seven species being thus figured 

 in the one number instead of six, as announced in the prospectus. 

 In every instance microscopical representations of the structure, 

 fructification, &c. will appear, and all will be coloured. 



The descriptive portion will be much more full than in any pre- 

 vious work in which our native plants have been treated of, for the 

 ' Phycologia Britannica' will as a whole occupy a place by itself. 

 We have ample descriptions of the species ; their geographical dis-
