SCIENTIFIC COMMITTEE. 
Ixv 
A far-travelled root. — Mr. Fraser reported that Mr. Boodle had come to the 
conclusion that the root which Mr. Bowles showed at the Committee some 
time since was not the root of an Ailanthus, but of some species of Juglans, and 
Mr. Bowles said that /. nigra was certainly growing on his lawn a very long 
distance from the place where the root had been found. 
Double Antirrhinum. — Mr. Hay drew attention to the flowers of a double 
Antirrhinum which he showed. The spike was decidedly pretty and looked 
more like that of a stock than an Antirrhinum. 
Flowers capturing wasps. — Mr. Bowles showed the petals of a flower of Lilium 
Henryi, to draw attention to the groove near their base into which wasps forced 
their way to get to the nectar, and were unable to extricate themselves afterwards. 
Various hybrids. — Mr. Marsden Jones showed specimens of a hybrid between 
a double form of Dianthus fragrans and D. barbatus, which had double flowers 
and broader green instead of narrower glaucous leaves as in D. fragrans. He 
also showed a hybrid between Delphinium nudicaule and D. cashmirianum, the 
flowers of which showed traces of both parents. 
Proliferation in Cardamine dentata.- — Mr. Jones also showed drawings of a 
flower of Cardamine dentata, in which the ovary had opened and produced a 
vegetative growth from the base. 
Mr. Praeger's Monograph on Sedum. — Mr. Hales moved and Mr. Hosking 
seconded the following resolution, which was carried unanimously : " This 
Committee desires to record its appreciation of the excellent work on Sedums 
by Mr. Lloyd Praeger which appeared in the last number of the Society's Journal ; 
and they feel confident that work of this character must add to the prestige 
of their Journal." 
Malformed Nemesia and Oenothera. — Specimens of these plants were shown, 
the one from Mr. E. H. Berkley, the other from Mr. C. E. Pearson, in which the 
flower buds were multiplied to an extraordinary extent. Each bud was perfect, 
though the parts had not developed to the full, and both ovary and anthers 
appeared to be empty. In the Nemesia the flower-stalk had elongated as usual, 
giving the plant the appearance of an umbellifer, while in the Oenothera (which 
had appeared in a sowing of ' Golden Glow ' and had retained the reddish color- 
ation of the upper roots which characterizes that variety), there being no flower- 
stalk, the inflorescence was more like that of a beet. 
Scientific Committee, August 23, 1921. 
Rev. W. Wilks, M.A., in the Chair, three members, and Mr. E. A. Bunyard 
(visitor), present. 
Large leaf of Populus canadensis. — Mr. George Paul showed a leaf from a 
stool shoot of Populus canadensis, with one of P. lasiocarpa for comparison. 
The leaf exceeded that of the latter in size, measuring over eight inches in 
diameter. 
Melanthera sp. from Kenya. — -Mr. Van der Weyer sent flowers of a species 
of Melanthera from Kenya which had flowered in a greenhouse in 1920 and 
outdoors this year ; apparently setting seed, and coming freely from cuttings. 
Enations on Yucca filamentosa. — He also sent a piece of a leaf of Yucca fila- 
ment osa with a horn-like enation on the side near the apex similar to those 
which have before been shown to the Committee. 
Hybrid Buddleias.- — Some flowers of the F 2 generation of Buddleia globosa X 
magnifica were sent by Mr. Van der Weyer. The majority of the seedlings 
approached B. magnifica and none had given a cream spike. He also remarked 
that the F 2 generation of B. globosa x B. madagascariensis (which in F 1 gave 
flowers in orange balls slightly larger than those of B. globosa and without 
scent, the leaves being like those of madagascariensis) has leaves more like those 
of B. globosa. 
Various plants. — Mr. H. J. Elwes showed various plants from his garden, 
including Buphane (poison bulb), which requires heat and good feeding (fig. 
in Gard. Chron. from Salisbury, Rhodesia, at the opposite time of the year) ; 
Hedychium Elwesii, about 2 feet 6 inches high, with bronzy green leaves, purple 
below ; H. coronarium x Gardnerianum, a very sweet-scented, yellow-flowered 
cold-house plant like Gardnerianum ; Agapanthus inapertum, a comparatively 
new species. 
Solanum ' ovigerum.' — A plant shown under the name of Solanum ovigerum 
by the Hon. Vicary Gibbs was awarded a Botanical Certificate. [This plant 
was subsequently recognized as 5. texanum (S. integrifolium).]
