SCIENTIFIC COMMITTEE, OCTOBER 22. 



CCXXXV 



that although Art. xii. of the rules of horticultural nomenclature 

 (JouENAL E.H.S., vol. xxxvii. p. 151) permitted the use of names of 

 Latin form (wdth . signs of hybridity) for such crossbred plants as 

 this, it would be more convenient if vernacular names were chosen, 

 generally from the classics. In the instance under consideration, the 

 Committee recommended that the exhibitor should be asked to choose 

 such a name. 



Tomatos with pale, round spots. — Some Tomato fruits with pale 

 spots, circular in outline, about J inch in diameter, and each having a. 

 minute black spot in the centre, were sent from Highgate. Micro- 

 scopic examination failed to reveal the presence of a fungus, and the 

 Committee concluded the damage was probably the result of punctures 

 by a hemipterous insect, possibly white fly, or a species of Lygus. 



Potatos with super-tuheration. — Potatos showing growth after the 

 first stage of tuber production were sent from Bush Hill Park. These 

 are frequent this season, owing to rains during August. 



Glassiness in Apple. — A specimen was sent from Battle showing 

 the peculiar soddening of the tissue called glassiness. This is not at all 

 infrequent this season, several specimens having been received at the 

 Society's laboratory, and Mr. Chittenden said he had found similar 

 fruits on trees at Wisley (on the sunny side of the tree) as early as 

 My. 



Scientific Committee, Octobee 22, 1912. 



Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, and eleven 



members present. 



Bordeaux injury. — Mr. Hill, M.A., showed, on behalf of Mr. 

 Massee, V.M.H., some Apples to illustrate the russeting due to the 

 action of Bordeaux mixture upon their skins. 



Antirrhinum sporting. — Mr. Chittenden showed from a garden near 

 London stems of an Antirrhinum bearing short, leafy growths in the 

 axils of the bracts instead of flowers. The leaves were very small. 

 A similar specimen was subsequently sent by Messrs. E. Veitch, of 

 Exeter. 



Rhododendron sporting. — Sir George Holford exhibited a Ehodo- 

 dendron raised from the cross R. javanicum ' Euby ' x R. javanicum 

 ' Ne Plus Ultra.' It bore two inflorescences, one having bright red 

 flowers, the other not quite so deep in colour and with yellow corolla 

 tubes. The two parents had both crimson-scarlet flowers of slightly 

 different shades. The flowers on the two trusses were of the same 

 age. Ten plants of the cross had flowered, each bearing flowers of a 

 richer colour than either of the parents, but none of the others had 

 shown similar sporting proclivities. 



Grey Oak. — Dr. Voelcker sent a piece of Oak wood of .a peculiar 

 greyish-blue colour from a tree struck by lightning. The Committee 

 thought the coloration was probably the result of exposure to sun and 

 air, especially as the tint approached that of weathered Oak palings.
