and wart resistance in potatos ; and to Pantia Ralli, Esq., for work in raising 
Brassolaeliocattleya x dtrina, the result of a cross of a Brassolaelia with Catileya 
citrina, producing a lemon flower with a fringed labellum and a downward 
tendency of growth. 
Scientific Committee, November 2, 1920. 
Mr. E. A. Bowles, M.A., in the Chair, and seven members, with Mr. E, A. 
BuNYARD and Mr. Crane, visitors, present. 
White and Grey Poplars. — Mr. J. Eraser showed specimens to illustrate 
the differences between these two species, especially referring to Populus alba 
var. nivea, recognizable by its small catkins, of which only the female form 
is known in England, the male occurring in the Channel Islands, and to the 
thicker and more clumsy branches of P. canescens, the catkins of which are 
long. Both species show parallel variations in the amount of tomentum. 
Pear-shaped Sport of Apple. — Mr. Bunyard showed an apple of the variety 
' Houblon,' remarkably like a pear in shape, similar to sports which had been 
shown at previous meetings and to the pear- apple, in which variety, however, 
the form is constant. 
Variation in Leaves of Raspberry. — Mr. Bunyard also showed a piece of a 
raspberry cane giving rise from a sucker to a flat-leaved spring growth, whereas 
the principal canes were almost| smooth and the leaves curled and crinkled. 
Such canes were generally regarded as seedlings or rogues, and destroyed, but 
it was not clear whether they were different, because one was juvenile, the 
other aged, or produced at a different season, or whether we have to deal with " 
a chimera. 
Variation in Apples. — ^Mr. Crane showed fruits of Cox's Orange Pippin 
from different trees, to illustrate the remarkable range of variation seen in 
this ' fruit. One was ver}'- highly coloured and the other orange, sometimes 
with red streaks, sometimes without. Both were from orchard-house trees. 
Apple-blossom Weevil. — Mr. Chittenden showed, on behalf of Mr. G. Fox 
Wilson, a photograph of some Apple-blossom Weevils on an apple branch, to 
illustrate the efficient manner in which their colouring hides them. Many 
pass summer and winter there hidden, others are found among the roots of 
grasses. 
Scientific Committee, November 16, 1920. 
Mr. E. A. Bowles, M.A., in the Chair, and five members present. 
Fruit of Feijoa Sellowiana. — Mr. E. A. Bowles showed specimens of this 
highly aromatic fruit from Mr. Woodward's garden at Nice. This Myrtaceous 
shrub is not very hardy in England, but where it grows it flowers freely. 
Weevil Galls of Turnips. — Mr. Chittenden showed, on behalf of Mr. G. Fox 
Wilson, photographs of galls on roots of Turnips, caused by the weevil Ceutor- 
rhynchus sulcicollis. The galls had been bitten through and the larvae which 
they contained eaten by mice and birds. 
The late Mr. Reginald Farrer. — The Committee unanimously desired to 
express their condolence with the late Mr. Farrer's parents in the loss which 
they and horticulture have sustained through his untimely death in Upper 
Burmah. 
Scientific Committee, November 30, 1920. 
Mr. E. A. Bowles, M.A., in the Chair, and six members present. 
Mints. — ^Mr. J. Eraser showed a series of hybrid mints and their varieties, 
comparing his specimens with the published descriptions. 
Variation in Eucalyptus citriodora. — Mr. Worsley showed leaves of Euca- 
lyptus citriodora from seedlings, some of which were of the common citriodora 
type, with glandular leaves and a cup-shaped base to the blade, the other with 
almost glabrous leaves, little odour, and almost without the cup-shaped base 
to the blade. These two forms had appeared upon seedlings, but he had now 
found both on one plant. 
Momordica cochinchinensis . — Fruit of this plant, the seeds of which contain 
a very quick-drying oil, were sent from Kew.
