The road frequently leads through copses of cork-trees and pines, 
and large barren tracts are seen covered with Chamerops 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 Alge inhabiting the Shores of the 
British Islands. By Witi1am Henry Harvey, M.D., M.R.LA., 
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 EHlachistee, 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-
