62 THE VOYAGE OF H.M.S. CHALLENGER 



particulars are given of its introduction into the Bermudas. Among Sir J. H. Lefroy's 

 notes are some dimensions of trees of Coccoloba uvifera growing at Ardsheal. One had a 

 trunk six feet four inches in girth. Bat the writer says, " These may be called upright 

 branches rather than stems, many of them springing from a very broad base or trunk only 

 two or three feet in height, which is supported on a wide mass of thick and knotted roots 

 that are only partially covered by the sandy earth. One of these short trunks measures 

 twenty-one feet ten inches round, and has seven erect stems or branches."
