CXviii PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY 



This fungus is a native of Switzerland, and has previously been recorded 

 as attacking species of this section of Saxifraga in this country (see 

 Journal of Botany, 1908, p. 153). Puccinia Pazschkei differs from 

 P. saxifragae in having the teleutospores warted instead of striate, 

 and it does not appear to attack the British species of Saxifrage. 



Scientific Committee, July 15, 1913. 



Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, and ten 

 members present. 



Proliferation in Rose. — Mr. J. T. Bennett-Poe, V.M.H., showed a 

 Rose having a fasciated and branched shoot bearing several buds 

 developed from its centre. The branch below the flower showed no 

 sign of fasciation. 



Lithiasis in Pear. — Mr. W. A. Voss sent a small Pear, ' Doyenne 

 Boussoch,' from a tree of about twenty-five years of age, showing 

 peculiar developments of " stone-cells " breaking through the 

 epidermis here and there. Only one or two fruits on the tree, which 

 was bearing a heavy crop, were affected, and these were from 

 the end of a branch. The trouble is one not commonly met with 

 in England, and has been attributed by German investigators to 

 insufficient water-supply. 



Alder diseased. — Mr. J. O'Brien, V.M.H., sent fruits of Alnus 

 gluiinosa, gathered near Le Touquet from a tree bearing many similar 

 ones, in which some of the carpels had grown out in a peculiar fashion, 

 becoming fleshy and somewhat curled, standing out like leafy 

 projections from the cones. The development of these peculiar 

 growths is due to the attack of the fungus Ascomyces alnitorquus. 



Poplar diseased. — The Ven. Archdeacon Meredith sent leaves of 

 a Poplar with large golden-yellow areas upon them, occupying in 

 some cases half the leaf surface, due to the fructification of Ascomyces 

 aureus, a fungus nearly allied to the one producing leaf-curl in Peaches. 

 One or two of the leaves showed on their upper surfaces the silvery 

 appearance characteristic of the attack of Slereum purpureum as seen 

 in Plums. 



Liparis lacerata. — Mr. J. O'Brien showed an inflorescence of 

 Liparis lacerata (Ridley, in Journ. Linn. Soc. xxii. 1886, p. 284. 

 Malay Peninsula, Perak, &c., Dist. Tenasserim. Borneo). A small 

 example is represented in Burbidge's drawings of Borneo plants 

 in the Natural History Museum. The species was little known until 

 it flowered with the Hon. N. Charles Rothschild, and was noted in the 

 " Gardeners' Chronicle," February 15, 1913, p. 99. from a plant sent to 

 him by a collector in Borneo. The present specimen, flowering with 

 Sir Marcus Samuel, was obtained from the same source. Some of the 

 flowers had dropped, but the spike was about nine inches in length. 

 Robinia Pseudacacia monophylla. — Mr. E. A. Bowles showed flowers
