Among nine Terebinthacee (two Anacardiee and seven Burserea), 
three only are referable to published species, the Zrattinickia rhoifolia, 
Willd. (with a trifid calyx, trifid corolla, and six, not five, stamens), 
from Barra, and two, or perhaps three Zcicz, from Santarem, closely 
allied to numerous specimens from Guiana and Brazil, which constitute, 
most probably, the 7. Guianensis, Aubl, and J. heterophylla, DC., but 
which it is difficult to identify with certainty, without comparison with 
authentic specimens. The following are the new species :— 
1. Cyrtospermum gummiferum, gen. nov.—Char. gen. CYRTOSPERMUM. E 
Calyx parvus, 5-partitus. Corolla... Stamina 10, sub disco a 
hypogyno inserta. Ovarium . . . Drupa ovoidea, erecta, acu- 
tiuscula, pericarpio tenui.  Ændocarpium osseum, dissepimento duro 
curvato separatum in loculos 2, altero parvo laterali vacuo, altero. 
hune fere cireumdante, sectione transversa hippocrepico. Semen 
unicum, loculo conforme et pariter curvatum, ex apice pendulum ; 
testa tenuis; albumen nullum; radicula brevis, supera; cotyledones 
late, carnosulæ, dissepimento ineumbentes.— Species unica C. gum- 
miferum.— Arbor 40-pedalis, ramulis crassis. Folia simplicia (fere 
Semecarpi), ad apices ramorum approximata, semipedalia v. paulo 
longiora, rarius fere pedalia, cuneato-oblonga, obtusissima v. retusa, - 
basi angustata et in petiolum brevem decurrentia, rigidula, glabra, - 
parallele penninervia et tenuiter reticulato-venosa. Panicule axil- 
lares, parum ramosæ, 3—4-pollieares. Flores ex reliquiis suppe- - 
tentibus parvi videntur, fascieulati. Drupe semipollicares, pur- -
