the plant is abundant it would be advi.sable to break up the pasture, 

 cultivate it well for two or three years with root crops, and then lay it 

 down with good and suitable seed " (pp. 735, 7H0, l.c). 



AnthriscAis sylvestris (Beaked Parsley), fig. 7. — Common in woods 

 and hedgebanks, sometimes spreading into fields. . . . Cases are recorded 

 of this weed being injurious to stock ; but this rarely happens, as it is 

 universally avoided." The species should not be allowed to spread from 

 seed (p. 73G, I.e.). 



Pulicaria dysenierica (Fleabane), fig. 8. — This plant occurs along 

 ditch sides, streams, and headlands of fields. It should be destroyed 

 (p. IHC), I.e.). 



Plantago media (Lesser Plantain), fig. 9. — " A common weed in 

 lawns and pastures. ... It may easily be distinguished from the larger 

 Plantain by its smaller spike of flowers, which are lavender-coloured 

 when in bloom, and by the leaves being without a stalk. This weed 

 cannot be got rid of unless its perennial root is spudded out " 

 (p. 737, I.e.). 



ItliinanlkuH Crista-rjalli (Yellow Rattle), fig. 10. — This comrfjf)n plant 

 is a root parasite. It is abundant in damp pastures and marshlands. To 

 prevent the spread of the weed the plant should be cat while in flower 

 (p. 737, i.e.). 



Verbena offieinalis (Vervain), fig. 11. — Reported from Hampshire as 

 injurious to pastures. " Plants should be prevented from seeding, but the 

 whole plant may be removed by pulling when the soil is soft with rain " 

 (p. 737, I.e.). 



Allium vineale (Crow Garlic), fig. 12. — " The whole plant is pervadea 

 with a garlic taste and odour, which is communicated to the milk and its 

 products. . . . To clear it out of a field where it is abundant it would 

 be necessary to break up the field with a somewhat deep plough, and 

 cultivate it, so as to clean the ground " (p. 738, I.e.). — B. N. 



FROM CURRENT HORTICULTURAL PERIODICALS. 



Abies arizonica (Merriam) ; A. lasiocarpa var. arizonica 



(Masters). By C. A. Purpus, of San Diego, California (Die Gart. 8G, 

 p. 427 ; coloured fig.). — Discovered in 1896 by Dr. Hart Merriam on the 

 mountains of Northern Arizona, where it was also seen by Purpus in 

 the summer of 1900, and who considers it to be the most striking of all 

 the West American Abies. It is especially distinguished by its peculiar 

 cork-like whitish bark and blue-grey foliage, much resembling in colour 

 that of Picea i)unfjenH. — A. H. K. 



Abies lasiocarpa var. arizonica. By M. T. M. {Gard. Chron. 

 p. 86 ; 9/2/1901). — The tree is very distinct for cultural purposes, the 

 colour of the foliage surpassing that of Picea j>?^7Zf7e72S arfjentca, and as 

 it grows at an altitude of 7,000 ft., exposed to great cold, it should be
