by Aublkt' under the luiine of Auoiia /o/if/i/o/la (fig-s. :233, 235), tlie 

 outer stamens are sterile and transformed into imbricated petaloid 

 blades, while the surface of the ripe fruit is also nearly smooth, features 

 sufficient to characterize a special section of the ^enus Ahercmoar 

 This genus consists of South American trei!s and shrubs, whose

^ We hiive called it Ftiscea {Adansonia, viii. 

 326). This section is also distinguislied by its 

 inflorescence, by these petaloid staniinodes ex- 

 ternal to the fertile stamens, by the union of the 

 styles at the top into a single mass, and by the 

 structure of the fruit, which finally becomes h 

 spherical woody mass, like a wooden ball hollowed 

 out into monos])ermous cells and whose surf ice 

 gives but little indication of the fact that this 

 multiple fruit really consists of a large number of 

 ovaries originally free (see fig. 235). 



3 It is in this way that they are arranged in 

 A. longifolia, represented in fig. 233. Moreover 

 we see that the bracts on the axes of the different 

 generations may have leaf-ljiids in their axils. 



There are also two flowers of difterent generations 

 in the inflorescence of Anona ? unijlora Dux. 

 {Mop., 7(5; UC, Prodr., i. 8G, n. 21; Icun. 

 Dcless., i. 23, t. 87), which is an Aberemoa, hut 

 whose specific name must needs be changed for 

 this reason. Accordingly we have proposed {Adan- 

 sonia, viii. 327) to call it Duquetia Candollei. 



* The situation of the inflorescence is lateral 

 in A. loiiffifolla. The uniparous cyme really arises 

 from the axil of a leaf, a leaf that has already 

 fallen, on a last year's branch. Beside it, and 

 from the same axil, a young branch developes at 

 the same time. Now the inflorescence rises 

 up and remains united to a very variable extent 

 by its jieduncle either to the young branch or to 

 the last year's one. Something analogous may 

 be observed in Monodora.
