[Plate 1] represents a branch of the coffee-tree in blossom and fruit, and the lettered figures at the foot have reference to the dissection of the flower and fruit.
A—The flower, cut open, to show the situation of the five filaments, with their summits lying upon them.
B—Represents the flower cup, with its four small indentations enclosing the germ or embryo seed-vessel, from the middle of which arises the style, terminated by the two reflexed spongy tops.
C—The fruit entire, marked at the top with a puncture like a navel.
D—The fruit open, to show that it consists ordinarily of two seeds, which are surrounded by the pulp.
E—The fruit cut horizontally, to show the seeds as they are placed erect, with their flat sides, together.
F—One of the seeds taken out, with the membrane or parchment upon it.
G—The same with the parchment torn open, to give a view of the seed.
H—The seed without the parchment.
Lindley and Paxton only enumerate two species: C. arabica, native of Yemen, and C. paniculata, indigenous to Guiana.
