b, represents the peach deprived of one half of its pnlpy exterior, or 

 panextern, and exposing the nut or panintern ; c, represents the 

 nut divested of one of its valves, and showing the seed d. 



Order 7th. Baccati, (from bacca, a berry,) simple, succulent fruits, 

 containing many separate seeds. The genera in this order are the 

 following : 



Pyridio}7j* (frora pericleo, to lie around;) this is a regular fruit, 

 crowned with the adhering calyx. The pericarp is fleshy, and has 

 several cells, each of which contains one or more seeds ; the em- 

 bryo has two cotyledons, Avhich are large and fleshy. This genus 

 contains the apple and pear. The apple, (Dlalits communis^) Fig. 

 102, has a round, fleshy pericarp, crowned with the calyx; the seeds 

 are enclosed in five carpels, or cells, ranged around in the axis of the 

 fruit ; the cells are composed of membranaceous valves. The seeds 

 are tunicated, or coated ; a, represents an entire pyridion ; 6, the 

 same cut vertically; and c, the same transversely.!

Ptpo, (fiom the Latui pepo, a melon,) this is a legulai monoce 

 phalous fruit with a radiating placenta, containing many seeds ; the 

 panextern is solid and dry ; the panintern is pulpy. The watermelon 

 is globular, and the cucumber oblong. Fig. 103, represents the cu 

 cuMis anguria, sometimes called prickly cucumber ; a, is the entire 

 pepo, which is spinous, three-celled, and many-seeded. The cehs 

 and seeds are shown b}^ the same fruit cut transversely, as at b ; c, 

 represents a seed, this is tunicated and dicotyledonous; cZ, the same 

 cut vertically.

t A singular tact is pbseivable in the fruit of the apple : when cut in slices trans- 

 versely, it exhibits in its substance an exact representation of the five petals which 

 existed in the flower ; I have never, in any botanical work, met with a notice of this 

 phenomenon, and know not on what physiological principles it can be explained.
