 Reason is not given for the change in the order, 

 which may have been unintended. Described to be 

 dioecious and tetrandrous in the Appendix to Lam- 

 bert's Monograph on the Genus Finns, in ii. 1828. 

 p. 32*. The account in Gard. Mag., i. 356, 357., 

 has been taken from this Appendix. " Dioe^cia 

 Tetrandria N." (Sweet, in his Hort. Brit., end of 

 ^^ 1830.) The N, impHes, Nuttall is the authority. 

 ■^ It is spoken of as dioecious- sexed in Gard. Mag., 

 ii. 350., vi. 483. and note * ; and Messrs. Prince, 

 nurserymen. New York, offer, in their catalogue 

 for 1832, plants of the female at seventy-five cents 

 (three quarters of a dollar) each ; and plants of the 

 male at a dollar each.

The following considerations are adducible, without violence, in relation 

 to the question, — Are the sexes of Maclura aurantiaca dioecious or monoo- 

 cious ? Of three fruits sent to the Conductor by Dr. Mease of Philadelphia, 

 noticed in VI. 103, 483., X. 61., it is stated of those noticed in VL 103., 

 X. 61., that they had been produced in the nursery of Mrs. M'Mahon, near 

 Philadelphia. It is probable that that mentioned in VI. 483. had been pro- 

 duced therein also ; but this is not stated. Now, in the notices of two in- 

 stances of fruit out of this nursery not any mention of a male tree or plant, 

 growing there is made ; which it is rather hkely that Dr. Mease would have 

 made had the case been so. Of the third fruit sent, noticed in X. 61., and 

 there stated to be out of the said nursery,' the Conductor, in the page cited,
