gecidiospores were applied on June 10 to the foliage of Phalaris 

 arundinacea, which in twenty days bore a Uredo with dark 

 orange or reddish brown spores. Further details of our culture 

 will be published shortly." 



Cronartium ribicola. — He also sent specimens of this fungus, 

 observing that they were gathered on July 3 in the garden of 

 Mr. C. J. Boyes, Oakwood House, Setch, near King's Lynn. 

 " For several years past I have been looking out for this fungus, 

 but until the above-named day without success. It occurred on 

 Black, White, and Red Currant bushes in both stages — viz. 

 Uredo and Teleuto spores. The parasite was found sparingly 

 in two gardens adjoining Oakwood House. Several Pines of 

 various species are growing in these gardens, but the season is 

 too advanced for the Peridermium to be encountered in its 

 perfect stage." Dr. Masters observed that this disease on Pinus 

 Strobus has been known for several years, but it is only now 

 that the fungus has been traced to its source on Currant bushes 

 by Mr. Plowright. 



Daisy, Monstrous. — Dr. Masters showed drawings of a very 

 unusual form of flower, in which the ray-florets had cohered 

 into a campanulate cup, the styles and stigmas uniting into a 

 column. 



Tsuga Pattoniana and T. Hookeriana. — He also showed 

 branches of these trees, pointing out the differences, though 

 regarded as the same species. Prof. E. Smith remarked upon 

 the great differences which obtain between the maritime 

 horizontal form of Cupressus macrocarpa and the erect fastigiate 

 inland variety. Mr. Henslow alluded to the fact that the 

 Deodar, so different from the Cedar of Lebanon in habit in this 

 country, resembles it in its native home on the Himalayas. 



Carnations attacked by Hylemyia Grubs. — In response to the 

 request for observations made by the Scientific Committee, 

 " W. D." writes as follows to the Journal of Horticulture, 

 July 14, page 33 : " The earliest stage of the operations of the 

 grub is to be seen about the early part of June, and any 

 symptoms of decay in the main or lateral stems of the plant 

 should be examined, when a very small yellow grub will be 

 found, changing to a nut-brown colour as it gets older, eating 

 out the heart of the stem, but it cannot be seen until the 

 attacked part is cut away and examined. It also attacks the
