370 REPORT ON THE PLANTS 
This tree, from the Capociras, near Barra do Rio Negro, is very 
unlike all other Trichilie known to me, and the ovules appeared to 
be solitary in each cell, even under a high magnifying power; but 
as Jussieu observes that they are often so closely combined as to ap- 
pear like a single ovule, it is possible such may be the case with 
this plant, or that, in the specimens before me, the flowers may be 
. sterile and the ovules imperfectly developed. In the absence of fruit 
I have, therefore, left it in Trichilia, to which it approaches nearer than 
to any other genus. 
The only plant belonging to Vitacee is a variety of Cissus sicyoides, 
Linn., from Santarem, with the leaves broadly but not deeply cordate, 
and sometimes scarcely more than truncate at the base, thus coming 
near to C. ovata, Lam., and showing that the two plants may very 
probably be mere varieties of one species, as already suggested by 
De Candolle. 
There are four Simarubee,—a variety of Simaruba versicolor, St. Hil., 
forming a bushy tree of about twenty feet in the campos near Santa- 
rem, having flowers rather smaller and more closely clustered than in 
. South Brazilian specimens, but precisely the same form as Blanchet’s 
. n.2727, referred by Planchon without hesitation to this species; and three 
 Sümnabe, all belonging to the small-flowered group, which come much 
nearer in general aspect to Simarudéa than to the large-flowered Simabe, 
although the structure of the flowers renders it necessary to associate 
them with the latter genus. One of these, a small irregularly-branched 
tree, from the south shore of the Rio Negro, near Barra, is the Simaba 
Guianensis, Aubl., or at any rate the common Guiana species, which 
. Planchon has, in all probability correctly, referred to the one so rudely 
figured by Aublet. The two following are new :— 
l. Simaba fetida, sp. n. ; caule arboreo, ramulis glabris, foliis glaber- 
rimis, foliolis 5-7 sicdidesddis obtusissimis emarginatisque, - 
- panieula laxa foliis longiore, floribus pro genere parvis, staminum 
squamis abbreviatis, ovario puberulo.—4r4or parva, ramulis leviter 
 angulatis glaucescentibus. ^ Foliola opposita, iria ultima digitata, | 
13-2 poll longa, 1-14 poll. lata, basi in petiolulum brevissimum 
longe angustata, integerrima, coriacea, nervis lateralibus subtus im- 
Tune et flores fere S. Guianensis. Petala vix 2 lineas 
- Drupe obovoideæ, rubræ, styli cicatrice versus apicem 
pericarpio crasso-carnoso, putamine lignoso oblique obovoideo
