Turning to .the fruits in fluid, to the figure from Dr. Trimen, and to that
accompanying Cervantes' account of Ule, these all agree in consisting of a fleshy
circular disk, 1-3 inches in diameter, clothed beneath and on the circumference
with densely imbricating triangular scales, and bearing on the upper surface 8-30
confluent orange-red, thick, coriaceous, one-seeded carpels, with more or less pro-
minent pyramidal crowns. These carpels present important differences, possibly
specific; but from the materials available it is not possible to determine what may
constitute a species amongst them, and I shall therefore confine myself to defining
the typical C. elastica more exactly than has hitherto been done, and follow this
by descriptions of the forms allied to it.
