b in ^g. 47.), which is situated in the axil of a leaf. Each flower consists 

 of a pitcher-shaped calyx, which includes an ovarium, and has, connected with 

 this, a thread-shaped and downy style that is extended»beyond the top of the 

 calyx to the length of nearly an inch, as may be learned from Nuttall and 

 Lambert. Not any corolla. In Jig. 47., a and c, portions of the style which 

 had remained in some of the flowers until the fruit was progressing to perfec- 

 tion, are shown. In these two figures, also, the situation of the nuts into 

 which the ovariums have at length been rendered, is shown. In a dried por- 

 tion of a fruit now present, that was, when undried, 3 in. in diameter, a cen- 

 tral roundish axis, about half an inch across in its narrowest diameter, more 

 in its broadest, is obvious, upon which the individual fruits or calyxes 

 are arranged : this axis is not rendered obvious in b o^ Jig. 47. The nuts 

 are not situate at the base of the calyx, but at some little distance up their 

 length ; each nut is about three eighths of an inch long, and half this broad, 

 compressed, oval, with blunt ends, and a notch in the uppermost of them. 

 The calyxes in the fruit have their tips consisting of seemingly four tumid 

 lobes unequal in size : these, and some difference in the height or length of 

 the calyxes or individual fruits, gives the surface of the entire fruit {Jig. 46.) 

 its tubercular appearance. 



The dried portion of a fruit, now present, has, when sraelled to, precisely 

 the scent of honeycomb, but in a fainter degree. 



The Size, Figure, Colour, Juiciness, and Use of the Fruit. — Dr. Mease, of 

 Philadelphia, has sent to the Conductor, at three different times, three several 

 fruits of the Madura aurantiaca, as noted in VI. 103., 483. ; X. 61. Of the 

 first sent, noticed in VI. 103., the Conductor has there observed, " We have 

 had a drawing and section of it made, of the full size, by Mr. Sowerby." The 

 figure of the section is presented in the same place, but not the figure of the 

 drawing mentioned ; implying, doubtless, the entire fruit. Fig.A^Q., in the pre- 

 sent notice, represents an entire fruit ; and as this figure has been lying 

 by, it is doubtless the figure then prepared, so that it {Jig. 46.), and the figure 

 of the section {Jig. 47.), repeated here from VI. 103., now present a fuller 

 representation of the first fruit sent by Dr. Mease : a in^g. 47. is, perhaps, 

 slightly magnified. On this fruit Dr. Mease has communicated (VI. 103.) 

 that " It weighed 15 oz. when pulled : but it is not ripe;" and the Conductor 

 has added, " It measures 9 in. round one way, and 9\ in. the other. The 

 colour is a greenish yellow ; the taste acid, it not being half rjpe„" On the 

 second fruit, noted in VI. 483., as received from Dr. Mease, not any particu- 

 lars are stated. On the third, which the Conductor has noticed (X. 61.) 

 receiving, he has noticed, " It is about the size of a large orange .... though 

 evidently gathered before it was fully ripe • . . ." Its diameter was 3 in. ; a 

 dried portion now (May, 1835) remaining has shrunk to 2 in. " The Macliira 

 is conspicuous by showy fruit, in size and external appearance resembling the 

 largest oranges." — James's Exjjedition to the Rocky Mountains, as quoted in 

 Gard, Mag, I. 357. M. aurantiaca " inhabits deep and fertile soils in valleys. 

 The Arkansa appears to be the northern limit of the range of the Maclura, 

 and neither on that river, nor on the Canadian, does the tree or the fruit 

 attain so considerable a size as in warmer latitudes. In many specimens of 

 the fruit examined by Major Long, at the time of his visit to Red River, in 

 1817, several were found measuring 5^ in. in diameter." — Id. and Ibid. Nut- 

 tall has remarked, " I cannot learn that any individual has ever seen its ripe 

 fruit. These [the unri[)e fruit Nuttall must have now meant, because, if he 

 had meant ripe fruit, then some one had seen and tasted it], according to the 

 report of Major Long (see his Narrative, ii. 158.) are quite as large as those 

 of the shaddock tree, yellow, and very beautiful to the eye, but, in his opinion, 

 always unpleasant to the taste." — Nuttall in Lambert's Appen., and quoted in 

 Gard. Mag. I. 357. The fruit is not esculent. — Rajinesque, in Gard. Mag. 

 viii. 247. I never knew the fruit to be used as an article of food. — A. H. 

 Sevier, delegate in the Congress of the United States from the territory of 

 Arkansas, where the Madura aurantiaca abounds. In a communication from
