hairy than usual of D. asperrima, Splitg. (Pl. Nov. Surinam., 1842, 
p. 1), published also by Miquel (Linnæa, vol. xviii. p. 611) under the 
name of D. Surinamensis. It is an intermediate form between the old 
D. rugosa, Poir., figured in Delessert's * Icones? under De Candolle's 
name of D. Brasiliana, and the D. radula, Mart., Herb. Fl. Bras. 
no. 239 ; all of which may possibly prove to be varieties of one species 
extending over tropical Brazil and Guiana, and perhaps also into Colum- 
bia and some of the West Indian islands. Mr. Spruce describes the 
first single specimen he gathered as from a low procumbent shrub, and 
those more generally distributed as from a shrubby climber attaining 
about fifteen feet in height, with pale green flowers, strongly smelling 
of ripe peaches, and usually apetalous; there are also a few specimens 
of a smoother variety, with more constantly petaliferous flowers. All 
were from the campos near Santarem. 
The Anonacee include the widely diffused Xylopia grandiflora, St. Hil., 
the Xylopia barbata, Mart., apparently confined to this part of Brazil, a 
new Anona, described below, and two Guiana species of Guatteria. The 
one, G. Ouregou, DC., has already been indicated in North Brazil; the 
other, G. Schomburgkiana, Mart. (Fl. Bras. Anon. p. 36), agrees in - 
every respect with Schomburgk’s specimens, except that the pedicels 
are perhaps rather longer. The same species appears again among 
Hostmann’s Surinam plants (no. 1221), and has been published by 
Steudel (Flora, 1843, p. 754) under the name of Anona Hostmanni. 
Mr. Spruce found it on gravelly hills near Santarem. The new Anona, 
above mentioned, was from the Serra d’Escamas, near Obidos, where it 
formed a dwarf shrub of about three feet high, allied in other respects 
to the A. tenuiflora, Mart. (Fl. Bras. Anon. p. 10. t. 3). There were, — 
unfortunately, but three or four. desta received. li may be thus
