William Baxter. 

 Botanic Garden, Oxford, Sept. 28. 1833. 



That true and elegant naturalist, Hurdis (an Oxonian), was 

 he who said, — 



" Not a tree, 



A plant, a leaf, a blossom, but contains 

 A folio volume; " 



and the proverbiality his saying has attained proves that the 

 truth of its sentiment is generally felt. Mr. Baxter con- 

 tributes not a little to illustrate its truth, not only in the above 

 communication, but in the cheap and excellent periodical now 

 in the course of publication, entitled Figures and Descriptions 

 of one Species in a Genus of the Flowering Plants of Britain, 

 In that work, a plurality of associations are drawn together 

 and connected with each of the plants figured, and among 

 these associations, not rarely a notice, from Mr. Baxter, of the 

 species of fungus which have been found to inhabit the plants' 

 leaves and herbage, is supplied. — J. D. 



The common Berberry (Berber is vulgaris L.) is perfectly harm- 

 less to the Crops of Wheat which may grow near it. (VI. 367.) 

 — To Mr. Babington*s pertinent practical fact (VI. 367.), 

 illustrative of this assertion, I would add, that the parasitic 

 fungus which diseases the leaves of the berberry is ^cidiuni 

 Berberidis Persoon, and is in species and genus most distinct 

 from the parasitic fungus, Puccini« Graminis Persoon, which 

 is frequently found infesting the herbage of crops of wheat. 

 A figure of ^cidium Berberidis is given in Loudon's Ency- 

 clopcedia of Plants, p. 1045. No. 16676*. ; and one of Pucciniflj 

 Graminis in p. 104-7. No. 16710. In hedgerows around corn 

 fields in some neighbourhoods, plants of the berberry are not 

 rare (by Shaker's Lane, near Bury St. Edmunds, as one in- 

 stance) ; and it is probable that the charging on the berberry 

 the diseasing of the wheat, or other corn, which has grown near 

 it, has arisen from the likely case of the berberry being infested 

 with its parasitic fungus, the ^cidium Berberidis Pers., at the
