IN the 13th volume of the Linnean Transactions, Mr. Lindley 
has described, under the name of Chamemeles coriacea, a plant 
which was originally discovered by Masson in Madeira, and 
named Crategus coriacea. ‘This description appears to be the 
only one, founded upon an examination of specimens, in exist- 
ence; the accounts given by DeCandolle and Sprengel in their 
latest works being apparently wholly derived from it, and not 
claiming to rank as independent descriptions by furnishing any 
fresh or additional particulars of their own. It may therefore 
be inferred that the plant is of sufficient rarity to render the’ 
completion of its history a matter of interest. This must be my 
apology for undertaking the task without having it in my power 
to consult Mr. Lindley’s original paper and description ; for 
which reason I shall confine myself principally in this place to 
an account of the fruit, which, not E mentioned by. DeCan-

sirous it should be honoured by a place in-the Transactions of
