Remarkable Formation of a Stem-root in a Willoiv. 



A paper by John Lowe, Esq., of Gainsborough, ' On a Remarkable 

 Formation of a Stem-root in the Decayed Trunk of a Willow,' was 

 read. The paper was communicated by Dr. Balfour. 



A sketch was exhibited of a large willow, in which a root had been 

 developed, in a peculiar manner, so as to form a main stem. Mr. 

 Lowe observed : — " The tree (Salix viminalis) having become decayed 

 in the centre, a root had evidently been sent down by a portion of the 

 upper extremity of the tree, through the rotten, sponge-like substance 

 which filled up the interior. Feeding upon this, and the moisture 

 absorbed by it, the root at length reached the ground, where it esta- 

 blished a firm hold. The circumference then died away, until, the 

 root now taking on the functions of the stem, and becoming entirely 

 denuded, at length became the only support of the living top. 

 The remaining part of the periphery only acts as a mechanical sup- 

 port. The circumference of the root-stem is eighteen inches at top, 

 and thirteen at the bifurcation, and about three feet above the ground. 

 It has latterly taken on more stem-functions, by putting forth several 

 branches. The tree is growing near Sleaford, where I have observed 

 its progress for some years." 



The reading of several papers was delayed till the next meeting of 

 the Society. 



A. G. More, Esq., of Trinity College, Cambridge, was elected an 

 Ordinary (Non-Resident) Fellow. 



The Phytological Club. 



A Botanical Association has recently been organized, with the 

 above title. Its objects are thus stated : — 



" The Phytological Club is established by individuals connected 

 with the profession of Pharmacy, who have associated themselves for 

 the purpose of mutual assistance in botanical pursuits. Amongst its 

 means for effecting this object, are the following : — The formation of 

 an herbarium of reference, the exchange of specimens between mem- 

 bers, the collection of facts relating to the popular uses of indigenous 

 plants, and correspondence with botanists in other countries, when 

 o))portiuiities offer."
