ported to new situations wliere the struggle was absent. Tlie Rev. INI. J. Berkeley 

 believed that he had lately ascertained the connexion of a hitherto mysterious 

 disease of the roots of peach-trees with an insect very similar to the PhijUoxcra. 



On tlie Flora of Moa'K % A. W. Hatxe, J/..-1. 



The 2-10 plants found in Moab from the beginning of February to the middle of 

 March belong to 58 natural orders, of which b)^ far the best represented are :— Legu- 

 minosm with 3-5 species, Compositte and Cruciferfe. each with 26, and Graminacea) 

 23. The remainder belonged to Liliaceas, ScrophulaT-iacea3, Labiatae, Boraginacene, 

 Umbelliferse, &c. From the great abundance of springs, the eastern shore of the 

 Dead Sea is comparatively fertile. The most conspicuous difference which results 

 is the abundance of the date-palm, of which, on tlie west, only a single clump sur- 

 vives near Jericho. 



Summari/ Anahjsls of the Flora of Sussex {Fluenofjams and Ferns). 

 % W. B.'Hemsi,ey. 

 The total number of indigenous species (after Babington's ' INIanual ') is about 

 1000. This number would be reduced by about 100 if we take Hooker's ' Student's 

 Flora ' for our authority on species. 



To the above numtier we may add 59 fully established introduced species, 

 bringing the total up to 1059. 

 Separating this number into the throe primary divisions, we haver- 

 Dicotyledons 77(5 species, or 73-28 per cent. 



Monocotyledons 250 „ 23-81 „ 



Acotyledons 33 „ 311 „ 



1059 100-00 



Herbaceous species 937 „ 88-47 per cent. 



Woody species 122 „ 11-53 „ 



1059 100<)0 



Perennial species 7t'>7 „ 72--12 per cent. 



Annual or biennial species 1'92 „ 27-58 „ 



1059 100-00 



A few of the more interesting featares of the Flora are : — number of species to 

 area (1461 square miles), species peculiar to certain formations, maritime species, 

 and rare species, especially those of the " Atlantic " and " Scottish " types. 



Maritime and salt-marsh species 76 



Peculiar to the chalk 50 



Essentially bog-plants 3(5 



Aquatic and marsh-plants 213 



Amongst rare water- and marsh -plants may be mentioned -. — Isnardla paliisln's, 

 Limnanthcmum nymplueokk's, Scirpus carin'ntus, 8. iriqueter, and Fotam«i/cion 

 acntifuUus. 



Belonging to the " Scottish "' type of Watson -.—^Pyrola media, ^Hahcfiaria 

 albifla, and ^Festuca si/Zvaft'ca, with several others, all very rare and local. 



Cicendia _filiformis, *Slhili(irpin ciiropo'a, *Vicia hitea,' Bartsia viscosa, ^Genista 

 pilosa, and Melittis Mclisso2)li)jllum may be noted as south-western tvpes exteudino- 

 to Sussex. ' ^ 



Alchemiila vulgaris and Care.v monlana are interesting on account of their distri- 

 bution. 



A prominent feature of the Wealden flora is the extent of heath laud and the 

 great size the heath attains.
