The fruits of Leucojum, which are of considerable size, reinain on the stalk 

 for some time, floating (from their porous structure) iipon the water until 

 disarticulation of the stalk takes place, when they are carried down the 

 stream till they become stranded on the margin among the flotsam and 

 jetsam. There decay of the cellular structure takes place, first at three 

 places on the apex of the fruit, through which the seeds escape. I have 

 seen large quantities of the frviits (resembling small olives) on the streams in 

 this district. It is to be hoped that this great adornment of our rivers will 

 not be too recklessly gatliered. Large quantities from Shilhngford have been 

 sold in the Oxford streets recently. 



Leucojum is recorded for Oxfordshire, Bucks, and North Wilts.

 Alien. Pointed out to me by the late Mr. Gr. Harris of Oxford, in the hedge 



near Bagley Wood, but I coiild find no evidence as to its being a garden 



escape, as it was not near houses, nor could I find it in any of the gardens at 



Kennington. 



A stranger in 1894 brought me some specimens which he said he had 



gathered in a wood on Boar's Hill, but I have not been able to corroborate 



his statement.
