CXviii PKOCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



not gone far the two anther lobes could be seen around the mouth of the 

 spur. 



Malformed Orchid. — Mr. Eolfe, A.L.S., exhibited an Odontoglossum in 

 which the petals had acquired somewhat the coloration of the lip. 



Primrose flowering. — Mr. A. W. Hill, F.L.S., said that there was at 

 present flowering at Kew a common primrose which had been brought 

 from Shetland last year, and had thus retained the habit of flowering 

 at the season usual in Shetland. 



Tr achy carpus excelsus monoecious. — Mr. Bowles exhibited an in- 

 florescence of Trachy carpus excelsus, and remarked that although most of 

 the flowers were staminate in the inflorescence for some years, a few 

 pistillate flowers had developed and had produced fruit. This was most 

 evident in the inflorescences which had developed late in the season. 



Scientific Committee, June 22, 1909. 



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

 members present and Professor Hugo de Vries, visitor. 



Jessamine shoot with adventitious roots. — Mr. Saunders, F.L.S., 

 showed shoots of white jessamine from a wall, having large numbers 

 of adventitious roots springing from all round the nodes on the stem, 

 and occasionally from internodes. It was suggested that possibly the 

 roots had become dry, and this had induced the plant to attempt to 

 make roots at other parts of the stem. Mr. Pickering, F.E.S., mentioned 

 that the peculiarity of producing abundant adventitious roots appeared 

 to be innate in certain varieties of apples, especially in ' Northern Spy,' 

 the variety so largely used for stocks in New Zealand and other places. 

 Mr. Chittenden, F.L.S., remarked that the same character was to be seen 

 in the variety 1 Oslin,' a variety long ago known as the ' Burrknot/ on 

 account of the frequent formation of burrs upon the branches. 



Exotic Solarium, — Mr. A. W. Sutton, V.M.H., exhibited a flowering 

 plant of a Solanum, the seed of which had been sent him by a corre- 

 spondent at Monte Video, collected in Uruguay, and called by him 

 "a wild Tomato." The plant was referred to the secretary for further 

 examination. It proved to be Solanum sisymbrifolium, first introduced 

 about the beginning of the last century. 



Malformations in Trifoliums. — Mr. Fraser, F.L.S., showed examples 

 of Trifolium hybridum var. elegans (Lavi) with typical forms for 

 comparison, collected at Coulsdon, Surrey, in which the pedicels were 

 elongated and the pistil elongated and stipitate. He also showed 

 T. fragiferum, collected at Mitcham, with axial proliferation of the 

 inflorescence, and T. dubium, in which the pedicels of the original 

 inflorescence were many times branched and bore many capitula, the 

 sepals showed partial phyllody, the stamens pistilody, the pistils, which 

 were stipitate, showed phyllody ; in many flowers axial proliferation was 

 to be seen, and in some cases the capitulum became an elongated raceme. 



Flowers of Streptocarpus malformed. — Mr. Odell showed flowers of 

 Streptocarpus malformed in a manner similar to those exhibited by him
