Comparing these, it is seen that with both stocks greater growth 

 was produced by the pruned trees in the first year, and this was true 

 of all the ten sets in the experiment. 



In the second year the same is true for * Peasgood's Nonesuch ' 

 and for all the other varieties on Paradise stock, but three of the five 

 varieties on Crab stock gave greater growth in the trees not pruned 

 in the season of planting. 



In 1914 all the trees on Paradise stock pruned in the season of 

 planting again gave greater growth than did those not pruned, but 

 four of the five varieties on Crab stock gave greater growth in the 

 trees not pruned in the season of planting. 



The fifth, which behaved like those on Paradise stock (as it did in 

 1913), was ' Mr. Gladstone,' and this, from its different habit of growth, 

 might be expected to behave abnormally. These results uphold the 

 advocates of pruning in the season of planting so far as dealing with 

 trees on Paradise stock is concerned, but they also suggest that trees 

 on Crab stock in which the pruning in the season of planting was 

 neglected may tend to recover in time, and they help to explain the 

 differences of results so frequently reported. 



Calanthe x Branchii. — Mr. Gurney Wilson, F.L.S., drew attention 

 to the plant shown at the last meeting in order to show that crosses 

 had previously been made between the evergreen and deciduous 

 species of Calanthe, referring to the account of the exhibitions given 

 in the Gardeners' Chronicle vol. xx. (1896), p. 602, when Messrs. 

 Sander, on November 10, showed Calanthe x alhata (C. veratrifolia 

 X C. X Cooksonii x Sedenii), " a curious break between the ever- 

 green and the deciduous Calanthes with white flowers, intermediate 

 in form between the parents," mentioned in the Journal R.H.S., 

 vol. 20. p. ccxv ; and to Card. Chron, vol. xxxiv. (1903), p. 310, 

 when, on October 27, Mr. H. J. Elwes showed a spike of a Calanthe, 

 subsequently called C. X Elwesii. This was a cross between C. 

 veratrifolia and C. Stevensii, " a singular hybrid between the ever- 

 green and the deciduous sections, and with white flowers apparently 

 intermediate. The plant was said to resemble C. veratrifolia in 

 habit." 



Scientific Committee, December 15, 1914. 



Mr. E.. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, with nine 

 members present, and Miss C. Pellew, and Mr. J. Coutts, 

 visitors. 



Pelargonium hybrids. — Mr. J. Eraser, F.L.S., showed dried 

 specimens to illustrate the variation in certain forms, such as Pelar- 

 gonium X Moreanum, and made remarks on the origin of certain 

 hybrids. 



Primula floribunda, &c. — Prof. W. Bateson, F.R.S., exhibited a 

 range of forms raised between a plant of Veitch's form of Primula
