Lemon — On the Structure and Development of the. ^ L. S.^Ross. 



(Bot. Gaz. XV. 262-267, PL xvi). 



From what is evidently careful study and examination, the 

 author says: ** that every part of the fruit has its origin from 

 some part of the leaf." The pulp clubs are' stated to be derived 

 from the leaf hairs, and in this connection it is of interest to note 

 that under the title " The Ideal Ovary," Mr. E. E. Sterns (BULLE- 

 TIN, xvi. I'j) says : ''Apropos of the Orange I may add here the 

 observation that the stalked, elongated, juice-filled cells of the 

 pulp, springing from the inner surface of the carpellary leaf, are 

 true trichomes in structure and position, and therefore, when we 

 revel in the fruits of Citrus Aurajitmm, we are, morphologically 

 speaking, eating hairs/' The excellent figures greatly assist in 

 understanding what has already been written on the subject.
