that the supposition of a leaf-like expansion of the elements of a 

 single stem is insufficient to explain the usual appearances, and is 

 founded on a false analogy between fasciated and certain other ano • 

 malous stems." 



The specimens exhibited were from a collection formed by the 

 author and now in the Museum of Queen's College, Cork, They 

 consisted of — 1, an intimate adherence of two stems of Bunium 

 flexuosum ; 2, an entire adherence of two stems with their heads of 

 flowers of Hieracium aureum, and of two or more stems of Primula 

 veris ; 3, a fasciated stem of Ranunculus bulbosus, with the terminal 

 flower formed by the union of two, and the stem showing other signs 

 of composition ; 4, a fasciated stem of Cheiranthus Cheiri, apparently 

 consisting of at least three united branches ; 5, a fasciated stem of 

 Veronica maritima ; 6, two stems of the same plant, in which the 

 buds which usually produce individual flowers have produced se- 

 condary stems themselves flower-bearing, so as to transform a simple 

 into a compound spike; 7, a fasciated stem of Aucuha Japonica, 

 seeming to prove the composite nature of such stems ; 8, a fasciated 

 stem of Cotoneaster microphylla, in which the composite structure is 

 peculiarly evident ; 9, a fasciated stem of Fraxinus excelsior showing 

 a crowd of buds and of small branches in a linear series at the ex- 

 tremity of fasciated portions, and also showing the curved contrac- 

 tion of the fasciated branches from weaker branches being connected 

 with a stronger one. The author also referred to a remarkable 

 fasciculation ot Asparagus officinalis in the same collection, the upper 

 portion of which is spirally twisted, and the crowded branches from 

 which seem to prove the presence of several stems ; and to some fine 

 specimens of fasciations from the Society's collection which were 

 placed upon the table.
