Rhodostachys andina. — Mr. Bowles also showed flowers of a Brome- 
liad raised from seed collected in Chile by Mr. Elwes, and probably 
Rhodostachys andina, figured in the Bot. Mag. t. 7148. 
Uncommon Fruits. — Fruits of a variety of Diospyros Kaki called 
' Vashomarri ' and of Encephalartos caffer were shown from the Duke 
of Devonshire's gardens at Chatsworth. 
Curious growth in Pear. — Mr. Sandeman, of Ware, sent a curious 
hard growth, consisting largely of sclerenchymatous cells, from the 
inside of a Pitmaston Duchess Pear. It seemed to be of gall nature, 
for on cutting it open two grubs of an unknown species were found 
feeding in it. 
Scientific Committee, November 21, 1916. 
Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, and six members 
present. 
Ptelea trifoliata. — Mr. W. C. Worsdell, F.L.S., showed shoots of 
Ptelea trifoliata seedlings with five leaflets. The tree itself bears tri- 
foliate leaflets, but suckers at times have five leaflets, as in the case of 
the shoots shown, so that this character appears to be confined to the 
juvenile stage. No specimens in the Herbarium at Kew or the British 
Museum show five leaflets. 
Damage by Stoke-hole Fumes &c. — Dr. J. A. Voelcker drew attention 
to specimens he had received showing damage to various plants, par- 
ticularly in the occurrence of brown spots on the leaf -tissue by fumes 
from coke fires and ovens. 
Damage to Apple by Capsid Bugs.— Mr. E. M. Holmes, F.L.S., sent 
an apple from a Wisbech garden having warts, russeted on the outside, 
over its surface, each of them with a brown stain about the middle. 
These, which seem to have become increasingly prevalent during the 
past few years, are the result of attacks by Capsid bugs upon the 
growing fruits. 
Passiflora Failing to Flower. — Shoots of a Passion Flower which 
failed to produce flowers were received from Ashford. Neither the 
parent plant nor offshoots from it planted in different spots had 
flowered, and inspection of the shoots showed that they bore the leaves 
characteristic of immature shoots, not those characteristic of flowering 
shoots. It appears that the offshoots from Passifloras almost always 
take a considerable time to arrive at the flowering condition. 
Scientific Committee, December 5, 1916. 
Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, and eight 
members present. 
Terrestrial Orchid from New Zealand.— Mr. H. J. Elwes, F.R.S., 
referred to a terrestrial Orchid from New Zealand, grown from tubers
