FUSAEA AND GEANTHEMUM, NEW GENERA. 
One noteworthy plant which has been placed under Duguetia 
must undoubtedly be removed from that genus. It was originally 
described (1775) by Aublet under the name Annona longifolia; but 
Baillon, notwithstanding the fact that the carpels become solidified 
into a fleshy syncarpium instead of remaining discrete, as in Dugue- 
tia, that the hairs of the indument clothing its new growth are simple 
instead of stellate, and that the stamens are radically different from 
those of the latter genus, placed this plant in the genus Duguetia, 
under the name D. longifolia, setting it apart, however, from the 
rest of the genus under the sectional name Fusaea. That it is not 
congeneric with the plants of the genus Duguetia is so evident that 
the present writer does not hesitate to raise Baillon’s section to the 
dignity of a genus, which must also include Annona rhombipetala 
Ruiz & Pav. 
Another plant which must receive generic distinction is Anona 
rhizantha Eichl2 This species, though resembling Duguetia in its 
stellate-hairy and scurfy indument and in the discrete carpels of its 
fruit, differs radically from it as well as from Annona in its peculiar 
stamens, which closely resemble those of the genus Raimondia, in 
being devoid of an expanded head or swelling at the tip of the con- 
nective above the pollen sacs. From Raimondia it is separated by 
the character of its fruit as well as by its indument and the much 
greater development of the inner petals of its corolla. This plant 
was placed in the genus Aberemoa (Duguetia) by Robert E. F ries, 
who set it apart from the rest of the genus under the sectional name 
Geanthemum. From the peculiarities above noted, however, it is 
evident that it cannot be included in the genus and the present writer 
feels compelled to raise Fries’s section to generic dignity.

Duguetia, section Fusaea Baill. Adansonia 8: 326. 1868. 
Stem subsarmentose, branching, the younger parts, including petioles and 
peduncles, clothed with simple hairs; flowers perfect; calyx relatively large, 
8-parted, the lobes sometimes separate nearly to the base, sometimes united for 
a great part of their length and irregularly torn in anthesis (Sagot) ; leaves 
alternate, entire; flowers (fig. 73) perfect; petals large, sericeous-pilose, all 
imbricate, ovate-spatulate, the inner ones somewhat larger than the outer; 
outer row of stamens sterile, converted into small obovate imbricated petaloid 
appendages surrounding the androecium; inner stamens fertile, with the con- 
nectives dilated at the apex over the pollen sacs; fruit (synearpium) globose,
