Lin. syst. Monadélphia, Polydndria. Stamens 20, with the 
filaments connected into a tube at the base; cells of anthers 
drawn out. Disk annular, 20-toothed, surrounding the ovary. 
Stigma 5-lobed. Fruit drupe-formed, containing a 5-celled pu- 
tamen; cells 2-seeded from abortion, each separated by a bony dis- 
sepiment.—Trees flowing with balsam. Leaves entire, commonly 
margined by small gland-like dots, with the limb running down 
the petiole, and even down the stem, therefore sessile. Flowers 
axillary and terminal, corymbose, and irregularly cymose. 
1 H. parvirro‘rum (St. Hil. fl. bras. 2. p. 89.) leaves short, 
obovate, tapering into the petiole, emarginate and mucronulate 
at the apex; inflorescence longer than the leaves: peduncles 
and petals smooth. h.S. Native of Brazil in the province of 
Rio Janeiro. Petals green.

2 H. monra‘nvum (St. Hil. fl. bras. 2. p. 90.) leaves sessile, ob-

Geraes. Petals green.

3 H. parsamirervum (Aubl. guian. 1. p. 564. t. 225.) leaves 
ovate-oblong, half stem-clasping, with a decurrent nerve on 
the back; inflorescence longer than the leaves ; peduncles 
smooth as well as the petals. h.S. Native of Guiana and 
Cayenne. Myrodéndron amplexicaúle, Willd. spec. 2. p. 1171. 
Bark thick, abounding in red balsamic fluid, resembling styrax in 
smell; after it has exuded from the bark it becomes brittle and 
transparent, and when burnt affords a very agreeable odour. 
The negroes and the natives of Guiana use the bark for the 
purpose of slips to make flambeaus. They also use the wood 
in building their houses. The resin, according to Aublet, might

be used medicinally in the same manner as balsam of Peru. The 
tree is called Red-wood by the Creoles on account of the wood 
being red.

4 H. crassiròLıum (Mart. fl. bras. 2. p. 143. t. 198.) leaves 
coriaceous, stalked, obovate-oblong, entire; petioles winged; 
petals pubescent on the back. h .S. Native of Brazil on mount 
Serra de Arara-coara, on the confines of Peru. Cymes axillary, 
trichotomous. Flowers small, white. 
Thick-leaved Humirium. Tree 8 to 12 feet. 
5 H. rrorrwu'npum (Mart. fl. bras. 2. p. 145. t. 199.) leaves 
obovate or oblong, with a short acumen at the tip, emarginate, 
quite entire, tapering into the short petiole ; branches and pedicels 
2-edged ; petals smooth. h. S. Native of Brazil in the 
province of Bahia. Cymes trichotomous, axillary. Flowers small, 
white. 
Bundle-flowered Humirium. Tree 20 to 30 feet. 
Cult. These elegant trees will thrive well in a mixture of 
loam and sand, and ripened cuttings will root in sand under a 
hand-glass, in heat.
