report, Prof. Oliver explained that the present contribution could 

 only be regarded as a very imperfect statement of the subject, 

 and that he was busily employed in following up some of the 

 more novel lines which he has indicated." Prof. M. Foster 

 moved, and Mr. McLachlan seconded the motion, that the report 

 should be presented to the Council. 



Arum with Two Spathes. — Dr. Masters exhibited a specimen 

 of this common phenomenon, and remarked that no florist had 

 made any attempt to fix it. The question was raised whether it 

 was desirable to do so, as some thought that two spathes were 

 no improvement to the flower. 



African Produce. — Messrs. J. Wrench & Sons forwarded 

 samples of leguminous and other seeds raised in South Africa from 

 English origin. As a general result they had remained constant 

 in character. The Committee expressed their thanks to the 

 exhibitors. 



Scientific Committee, March 14, 1893. 



Dr. Maxwell T. Masters, F.R.S., in the Chair, and 

 ten members present. 



Sargasso Weed. — Mr. Blandford exhibited a specimen 

 collected off the Azores. He also remarked upon a perfectly 

 successful experiment of bringing fresh green Cocoa-nuts from 

 Jamaica in the refrigerator of a vessel. 



Tipuloe in Soil. — Dr. Miiller exhibited some grubs which 

 were pronounced to be a species of this insect allied to the 

 common T. oleracea, or Daddy Long-legs. 



Blue Primulas. — Mr. Wilson exhibited about fifty varieties of 

 different shades of blue, plum-blue, and bluish-violet Primroses, 

 all being seedlings from the original " Scott Wilson," and grown 

 at Weybridge and Wisley. 



Knotted Oak Branch. — Dr. Masters exhibited a specimen of 

 this well-known peculiarity, the stems being sometimes used for 

 walking-sticks. He had referred it to a fungologist, who had 

 detected the presence of the fungus Dichaena discina. It was a 

 question, however, to be solved whether this fungus was the 

 cause of the knob-like protrusions or not. It was referred to 

 Prof. H. Marshall Ward for further examination and report. 



Cecidomya Taxi. — Prof. Farmer exhibited specimens of
