None of the species of this genus possess any beauty, but are cultivated in gardens 

 and nurseries to mix with other shrubs for variety. Their singularity perhaps more 

 than anything else procures them a place in the shrubbery. Gerarde tells us " it 

 groweth in the garden of the Eight Honourable the Lord Treasurer, my very good 

 lord and master, and by his htmse in the Strand. Pliny hath written of it : ' The 

 timber whereof is very like to that of white Maple.' " Our good friend, who was 

 always willing to find some " vertue " in every plant of which he writes, says : " The 

 nuts are moist and full of superfluous raw humours, and therefore they easily procure 

 a readiness to vomit and trouble the stomacke, and therefore they be not to be eaten." 

 Haller says children eat the kernels ; but it must have been hardy children that did so, 

 if we are to believe Gerarde. The nuts being smooth and hard are sometimes appro- 

 priated to chaplets of beads or rosaries by Eoman Catholics,
