CXxiv PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 
Aberrations in Tropaeolum majus.— Colonel H. E. Rawson, C.B., 
showed a further series of aberrations in Tropaeolum which he attri- 
buted to interference with the incidence of certain rays of light, 
brought about by shading in various ways. 
Scientific Committee, May 16, 1916. 
Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, and twelve 
members present. 
Bryanthus taxifolius. — Mr. J. Fraser, F.L.S., showed a specimen 
of the common British plant Bryanthus taxifolius collected in 1883 in 
the Sow of Atholl. He said it had recently been found again and its 
exact locality made known in a local paper, with the result that it 
had become almost if not quite extinct. 
Abnormal foliage of Haematoxylon. — Mr. W. Fawcett, F.L.S., 
showed a specimen of the foliage of Haematoxylon produced after the 
trees had been stripped by a hurricane. It was many times larger 
than the normal, which he also showed. The difference was similar 
to that which resulted from the complete cutting back of such plants 
as Ash and Euonymus europaeus, which immediately thereafter produce 
very much larger leaves than they normally bear. 
Tropaeolum malformed. — Col. H. E. Rawson, C.B., showed a further 
series of specimens illustrating malformations in Tropaeolum majus. 
In these the posterior petals had become stamens, and in one an 
anther had developed a small leaf -like appendage. In two instances 
axillary proliferation was also occurring in the flower. 
Double purple Anemone. — Mr. E. A. Bowles showed the flowers 
of the double Anemone nemorosa bracteata which develop a purplish 
colour as they become older and fade. He suggested that this was 
probably Clusius' Anemone purpurea fl. pi. 
Various Plants— -Mr. H. J. Elwes, F.R.S., showed a number of 
uncommon and interesting plants from his garden at Colesborne, 
including Notholirion macrophyllum (= Lilium Thompsonianum) . 
This plant rarely flowers in England, but is more to be relied upon, 
Mr. Elwes believes, if the bulbs are lifted every year and the small 
ones removed. A new Iris related to Iris japonica from Burma, 
called by Mr. Dykes I. Wattii. A beautiful white Paeony for which 
the name Paeonia Willmottiae had been proposed, and the rarely 
seen Alpinia nutans, of which Mr. Elwes said he had seen a form in 
Formosa with drooping racemes a foot in length. 
Dry-rot among Books. — Mr. W. G. Smith sent a painting to illustrate 
the following note : — " The drawing represents one book only from a 
collection of similar examples which were attacked by the fungus 
Merulius lachrymans in the library of F. J. Gurney, Esq., at Eggington, 
near Dunstable, in 1915. The growth of the fungus started from 
beneath the floor boards, whence it grew upwards and matured itself
