system, commencing, as is now becoming the more frequent plan, 

 with the less perfect plants. 



We had intended to have given the specific characters of all the 

 new species contained in this book, but find them to be so numerous 

 that space will not allow us to do so : we must therefore refer to the 

 work itself, which will no doubt soon, if indeed it is not already, be 

 in the hands of all those who are interested in the plants of the South 

 of Europe, only noticing here a few of the more interesting points. 

 Narcissus juncifolius, La Gasc. Foliis filiformibus, rigidis, acutis 

 convolutis, scapo gracili, subbifloro, brevioribus ; petalis ovato- 

 lanceolatis mucronulatis. — N. juncifolius alter. Clus. Hisp. 250. 

 N. Jonquilla, Linn. Foliis angustis, carnosis, angulosis, obtusius- 

 culis, scapo 2 — 6-floro longioribus ; petalis lanceolatis acutis. 

 — N . juncifolius prior . Clus. Hisp. 250. 

 The latter of these plants, which is the Jonquil of the gardens, 

 has not been noticed in its native locality since its first introduction 

 into cultivation by Clusius 250 years since. Mr. Webb finds it upon 

 the grassy slopes upon either side of the long range of the Sierra 

 Morena, to which range of mountains it appears to be entirely con- 

 fined. It is possible however, as suggested by Mr. Webb, that it 

 may be found hereafter on the chain of Atlas in the northern part of 

 Africa. The former species originally and correctly separated from 

 the Jonquil by Clusius inhabits the warmer and drier parts of the 

 coasts of the Mediterranean. 



Pages 11 to 15 are occupied by a very valuable catalogue, with 

 extended observations, and in several cases amended specific charac- 

 ters of all the species of Quercus (oaks) noticed by the author in 

 Spain and Mauritania, consisting of 1 1 species, the last of which, the 

 Q. pseudo-corcifera, Labill., but not of Desf. is considered as a new 

 species, and named Q. Calliprinos, Webb. 



Anthemis fuscata, Brot. is formed into a new genus, with the fol- 

 lowing characters and name (page 37.)
