XXXViii PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



Prunus, wild. — Mr. J. Fraser, F.L.S., exhibited dried fruiting 

 specimens of a Prunus which had small oval purple fruits, collected at 

 the top of Box Hill. He had not seen the plant in flower, but from 

 the form of the fruit, the shape of the foliage, and the shape of the stone, 

 he thought it probably a hybrid between the wild Sloe and one of the 

 cultivated Plums. 



Sequoia gigantea diseased. — Mr. A. Worsley said that trees of 

 Sequoia gigantea round Isleworth frequently died when they had 

 attained a height of 40 to 50 feet. One had recently died in his garden, 

 and on cutting up the part of the bole near the root he had found 

 stains of a greyish-purple colour evidently produced by the growth 

 of a fungus. 



Cypripedium niveum x C. insigne Sanderae ( = C. X Boltonii). — 

 Mr. R. A. Rolfe, A.L.S., exhibited a flower of a Cypripedium from 

 Mr. W. Bolton, of Wilderspool, from one of several plants raised from 

 C. X Boltonii, stated to be crossed with another form. All alike had 

 albino flowers, with a few minute brown spots on the standard. 

 C. x Boltonii itself provides a good example of a dominant white. 



Odontoglossum x Horsmanii. — Mr. Rolfe also exhibited a flower of an 

 Odontoglossum that flowered among some imported 0. Pescatorei with 

 Mr. W. Bazeley, Twyford, Berks. He referred it to 0. X Horsmanii, 

 Reichb., originally described as a natural hybrid between 0. Pescatorei 

 and 0. luteo-purpureum, but suggested that 0. sceplrum (not luteo- 

 purpureum) was the second parent, as it has the rounder shape and 

 broader segments of the latter, as was also the case with the earlier 

 form. The flower was cream-white, with a group of red-purple spots 

 on each segment, while the lip was yellow, with a red blotch in front 

 of the sceptrum-like crest. 



Oak with curious Foliage. — Mr. Bowles said he had received a com- 

 munication from Dr. Henry, who recognized the Oak, from which the 

 curiously -shaped leaves shown by him some time ago were derived, 

 as Quercus pedunculata var. scolopendri folia, a variety the origin of 

 which is not known. The tree from which the specimens were gathered 

 occupies a position in an old pasture, and is unlikely to have been 

 grafted. See Journal R.H.S. 40, p. clxxxi. 



J anuary -flowering Plants. — Mr. Bowles also exhibited flowering 

 specimens of Correa magnifica from a shrub on a south wall, Sycopsis 

 sinensis from one in the open, and Euphorbia biglanduhsa, as 

 examples of plants flowering normally in his garden in January. 



Scientific Committee, February 2, 1915. 



Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, with seventeen 

 members present and others. 



Primula malacoides &c.—Mr. A. Worsley showed an inflorescence of 

 P. malacoides (now bearing seed) in which the perianth was extremely 

 small. Since its introduction P. malacoides has produced a consider-
