This species does not appear to have been figured, with the exception of its fruit, and 

 seems to have been confounded with C. latifolia ; and therefore its characters as given by 

 modern botanists cannot be relied on ; that of Swartz is the only one on which we can 

 depend. Swartz describes it as a tree of middle height, with a smooth trunk, its branches 

 being erect, not spreading horizontally, and straight and angular. It grows in arid 

 stony places, near the seashore, in Jamaica. The leaves, near the summit of the branches, 

 are alternate, 2-3 lines apart, they are 4J-7^ inches long, 2-24 inches broad, on a thick 



petiole 2-3 lines long. The peduncle of the flower is 1} inch, of the fruit 2 inches long ; 

 the concave segments of the calyx are 1J inch long, 6 lines broad ; the tube of the corolla 

 is 1J inch long, with an oblique mouth 1 inch broad, a little below which it has a 

 transverse ringent upward duplicature on the ventral side ; the upper lip of the border is j 

 inch long, extremely broad ; the lower Up is \ inch long, with 3 short broad lobes. The fruit, 

 of which I have seen a specimen in the British Museum, is shaped exactly like that 

 figured by Gaertner, is 3f inches long, 3 inches in diameter, supported by the persistent 

 lignified disk, upon a somewhat slender peduncle; the pericarp is somewhat thinner than 

 is shown in Gaertner's drawing, is hard, and can scarcely be called brittle, pitted externally 

 with numerous very deep dots, internally is lined with a pithy submembranaceous laminar 

 polished coating, in which 4 main placentary nerves, cruciately disposed, are imbedded, the 

 intervening spaces being filled by a reticulated network of branching fibres. The seeds 

 are fewer in number, and much larger, than those in the preceding section, and are well
