 tomentose nor farinose), beautifully marked with the dark brown nerves.

• In order to save room, as the present is the last fasciculus to which the work can extend, we are obliged 

 to omit the notice of several interesting and some entirely new plants in this collection, but especially of 

 such as were found in Mexico during the previous voyage of Captain Beechey.
