variations in the seedlings he had obtained, and the Committee 

 recommended the award of a Certificate of Appreciation to Mr. 

 Grove. 



Lime Wood attacked by Fungus. — Mr. E. A. Bowles showed a 

 specimen of Lime from a branch which had fallen from a tree in the 

 avenue at Forty Hall, Enfield, in which the annual rings of wood were 

 separated from one another. This separation had evidently been 

 brought about by a fungus, the mycelium of which could be discerned 

 as a thin pellicle between the rings, but could not be further identi- 

 fied until fruit was obtainable. 



A Curious Onion. — Mr. H. J. Chapman showed a curious onion 

 consisting of a basal stem portion from which roots had developed 

 and a fistular leaf of over an inch in diameter and more than a foot 

 in length. It was perhaps the result of injury to the terminal buds 

 of the shoot, and the direction of all the food and water into one 

 channel. 



Abnormal Agapanthus. — Mrs. Bischoffsheim sent an inflorescence 

 of Agapanthus umbellatus having a few flowers branching from the 

 stem about three inches below the main bulk of them. The stem 

 bent sharply there, and owing to the tension set up had cracked and 

 broken. This kind of malformation is very common in Agapanthus. 



Malformed Cypripedium. — Mr. C. J. Lucas sent a curious mal- 

 formed specimen of Cypripedium warnhamensis X C. insigne upon 

 which Mr. W. C. Worsdell, F.L.S., reported as follows : — The anterior 

 sepal is separating, or rather has begun to divide, into its two original 

 components, as shown by the apical division and the extension of 

 the arc of insertion of the sepal towards the " posterior " side. One 

 of the narrow elongated petals had disappeared. The other had 

 become displaced in order to occupy the median posterior position 

 of the posterior sepal, which has also vanished. Thus there is 

 dimery of the corolla, lateral petal, and labellum in the median plane, 

 and a tendency to dimery of the calyx, which, if it had been carried 

 through, would have resulted in two sepals placed in the trans- 

 verse plane, at right angles to the two petals. The two lateral 

 stamens of the inner whorl, normally fertile in Cypripedium, are 

 here quite absent. Instead, the medium stamen of the inner whorl 

 is present and fertile just above the big staminode.

Outgrowths on Saxifrage leaf. — Mr. W. H. B. Fletcher, of Aldwich 

 Manor, Bognor, sent leaves of Saxifraga ligulata var. ciliata with 

 small curious leaf-like outgrowths at the junction of the petiole 

 and leaf-blade. 



Podophyllum Emodi. — Mr. H. J. Elwes, F.R.S., showed a fruit of
