1857.J REVIEWS. 247 



is still limited to sixteen octavo pages, and tlie original numbers 

 are retained. This is a valuable distinctive peculiarity of the 

 London Catalogue. The chief novelties are the following : — Ua- 

 nunculus Baudotii is introduced, vice R. confusus, now a variety 

 of the above. We have now got a Thalictrum minus, var. pubes- 

 cens. Draba verna has received a second ally called D. verna, 

 c, brachycarpa. Arabis ciliata is now attended hj A. b, hispida. 

 Viola Curtisii has also changed her state, and is now united 

 with V. lutea. Sagina maritima and S. apetala have been re- 

 spectively mated with S. densa and S. debilis. Rubus appears to 

 have received a slight diminution in the species, and a slight in- 

 crease in the varieties. There is a new comer in Onagracece, viz. 

 Epilobium rosmarinifolium ; in the same Order are also two va- 

 rieties recently introduced. Saxifraga hypnoides has lost several 

 joints from her tail, but it is still formidable enough. The Umbel- 

 lifers are very constant quantities, and the Composite are very 

 fluctuating. Hieracium has attained the respectable number 

 of thirty-three. There was a time in our remembrance when 

 this genus only mustered five species. This is an age of pro- 

 gress. Among the Salices, S. Helix has been degraded, and her 

 place is now vacant. No. 1005* is, like the Society under whose 

 auspices this Catalogue is published, in abeyance. The name 

 Epipactis ovalis, Bab., has been superseded by E. atrorubens, 

 Reich, The Potamogetons have received a considerable acces- 

 sion : they are now twenty-two. They were nineteen, with three 

 varieties, in the fourth edition. It is a subject of congratulation 

 among the more ancient of British botanists to see Hierochloe 

 borealis, like that ancient Celt, Divitiacus, restored again to a 

 place of dignity and honour. The species of the Order Characece 

 are now added for the first time. This is a summary of the 

 material differences between this fifth and the preceding fourth 

 edition. In the first list of exclusive species, Pceonia corallina 

 has been introduced to lead the band of interlopers, marked A. 

 This change has made a vacancy in No. 35, and Berberis vulgaris 

 has very appropriately been promoted to the vacant place. It 

 may be presumed that Reseda Phyteuma is a recent importation, 

 a new production of the ballast-heap. Hypericum anglicum has 

 moved into List B, worl^jng his way slowly upwards. Centaurea 

 paniculata is another candidate for admission; so is Veronica 

 peregrina. Viola stricta is now one of the species defuncta : it
