unavoidable in a work of such extent. To this succeeds a most 

 useful indexj glossarial and etymological, where the author amply 

 displays the extent and exactness of his acquirements in botanical 

 and classical knowledge. 



There is in the beginning a reference to the various works 

 quotedj an explanation of the abbreviations used, a systematic 

 table of the families (Orders) of British Plants, and the general 

 contents. 



On the whole it may, we believe, be confidently stated, and 

 indeed inferred from what we have above related of it, that this 

 work, on the subject it professes to treat, is the most complete of 

 any yet offered to the public ; and perhaps an additional recom-

On the Botany of the District lying betiveen the Rivers Cray, 

 Ravensbourne, and Thames ; being the first Report of the Bo-

The author of the above-named pamphlet informs his readers 

 that the limits af the district are defined " by a line .commencing 

 at the junction of the Ravensbourne with the Thames, thence

 source of the Cray, in Orpington ; thence along the Cray to its 

 influx into the Darent, along the Darent to its junction with the 

 Thames, and thence along the Kentish shore of the river to the 

 starting-point,^' 



The compiler of this interesting list is not quite accurate in 

 stating that the sole British example of Frankenia is confined to 

 salt-marshes on the eastern coast, unless he reckons St. Helenas 

 Spit, Isle of Wight, to be so situated. The writer of this notice 

 has collected it there, and it is registered in the ' Flora Vectensis ' 

 as a Vectian plant. In reference to Hutchinsia petrtea and 

 Centranthus Calcitrapa, the author very truly states that they 

 grow on the wall of Eltham Churchyard ; but it is respectfully 

 submitted whether there be any authority for what follows, viz. 

 " They are both of them escapes from the garden of a well-known 

 botanist, who lived there many years ago.'^ Another question 

 may be asked : What is Armeria tenuifolia ? — a misprint for 

 Arenaria tenuifolia?
