138 LETTER XXXVIII. 



The cells of the ovary contain about four ovules, placed 

 upon a prominent placenta {fig. 3. b.). The style 

 rises from between the points of the lobes of the 

 ovary, and is di^^ded at its apex into four obscure 

 teeth. The seed-vessel is a light brown dry capsule, 

 splitting into four coccoons {fig. 4. «.), in each of 

 which is a sinofle seed, and which surround the 

 thickened hardened gynobase (Jig. 4. b.). The seeds 

 are dark bro\\Ti, pitted, angular bodies {fig. 5.), con- 

 taining an embryo lying in the midst of fleshy albu- 

 men {fig. 6.). 



Such is the structure of Garden Rue, and the same 

 is found more or less in the numerous genera referred 

 to its tribe. As you are little likely to meet with 

 many of them, I will only remark that some are 

 curious, as Correa, for having their petals imited 

 into a tube, like that of a Monopetalous plant, and 

 that they do not diflPer much from the Orange Tribe 

 (Vol. I. p. 86. Plate VI. 2.), except in their dry split- 

 ting fruit, their great fleshy gjnobase, and thefr albu- 

 minous seeds.
