on both sides of an interior wall. Close to one of these walls were 
bookshelves and books. The fungus luxuriated among the books, some 
of which were placed one upon the other on the shelves ; it grew upon 
and in the bindings and amongst the leaves ; it made the leaves 
stick together, and reduced them to soft pasty masses ; it caused 
the paper to be broken and pieces to drop out. In favourable posi- 
tions the flesh of the fungus developed a thickness of from one to 
one and a half inches. On the surface a good typical hymenium was 
produced with abundant reddish-brown spores. As the books were 
removed, a colourless fluid dripped from them. 
Scientific Committee, June 6, 1916. 
Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, with ten members 
present, and Mr. R. Farrer, visitor. 
Certificates of Appreciation Recommended.' — A Certificate of Appre- 
ciation was recommended to Mr. H. J. Chapman for his work in raising 
Dutch Irises belonging to the Xiphium section, that flower about a 
fortnight earlier than the Spanish ; and to Messrs. Charlesworth for 
work in raising the new intergeneric hybrid Orchid, Wilsonara x 
insignis (Oncidioda X Charlesworthii x Odont. illustrissimum) , com- 
bining species of the genera Cochlioda, Oncidium, and Odontoglossum, 
exhibited by Mr. Gurney Wilson, F.L.S. 
Weldenia Candida. — A Botanical Certificate was recommended to 
this bog plant, with frogbit-like foliage, shown at the Chelsea meeting 
by Messrs. Bees, of Liverpool. 
Aberrations in Tropaeolum. — Col. H. E. Rawson, C.B., who recently 
showed pressed specimens of Tropaeolum majus in which multi- 
spurred peloria and proliferation had separately appeared on different 
plants, now exhibited specimens in which both were combined in the 
same flower as well as on the same plant. 
Allium narcissiflorum varying.* — Mr. Bowles drew attention to a 
slender form of A. narcissiflorum which Mr. Reuthe exhibited in the 
Hall, collected from the Alpes Maritimes. It had smaller flowers, 
narrower foliage, and longer stems than the normal form, which was 
also exhibited. 
Hybrid Saxifrages and Viola.* — Mr. Murray Hornibrook sent from 
his garden at Knapton, Abbeyleix, Queen's Co., two apparently hybrid 
Saxifrages and a hybrid Viola, with the following notes : 
" Saxifraga Aizo-retioides.— -This was a small plant sent to me, 
growing among the rosettes of a collected plant of S. aretioides. Mr. 
Irving, of Kew, who saw it here last year, took it back for comparison, 
and thinks it a natural hybrid, and intermediate between its parents. 
It seems nearer to 5. Aizoon, but note its Kalischia habit of growing 
from one tap-root ; in one of the plants sent (the flatter one) the 
rosettes lie so loosely on the surface that this characteristic is easily
