with five to fifteen divisions, and having usually alternating petaloid segments, 
and glands or scales in front of the outer divisions. Stamens perigynous, either 
single or in parcels of three or six, alternating with the outer divisions of the 
perianth ; anthers dithecal, with longitudinal dehiscence. Ovary partly 
adherent to the tube of the perianth, one-celled ; ovules numerous, anatropal, 
pendulous, attached to two, three, or five parietal placentas; styles three to 
five, simple, filiform, or subulate. Fruit either baccate or capsular. Seeds 
small, ovate; embryo in the axis of fleshy albumen; cotyledons leafy ; 
radicle superior. Trees or shrubs with alternate leaves, having deciduous 
stipules. It contains tropical plants, which do not possess any important 
properties. Lindley mentions eight genera, including thirty species. Exam- 
ples: Homalium, Nisa. 
OrverR 64. Samypacrea, the Samyda Family. Perianth four- to five- 
divided, usually colored inside; eestivation somewhat imbricate. Stamens 
inserted into the tube of the perianth, two, three, or four times’ as many as 
its divisions, either all fertile, or the alternate ones sterile, shorter, and 
fringed ; filaments monadelphous at the base; anthers erect, ovate, two-celled. 
Ovary free, one-celled; ovules 00, attached to parietal placentas, semi-anatro- 
pal; style one, filiform; stigma capitate or slightly lobed. Fruita coriaceous, 
unilocular, three- to five-valved capsule, partially dehiscent. Seeds 00, fixed 
irregularly on the pulpy inner surface of the valves, with a fleshy arillus, and 
a hollowed hilum; embryo large, in the midst of oily or fleshy albumen; 
cotyledons ovate, foliaceous ; radicle pointing to the extremity remote from the 
hilum. ‘Trees or shrubs, with alternate, simple, stipulate leaves, usually hav- 
ing pellucid, round, or linear markings. Natives of tropical regions, chiefly in 
America. There are five known genera, and eighty species. Examples: 
Samyda, Casearia. 
OrpEr 65. CHAILLETIACE®, the Chailletia Family. Perianth five-parted, 
with an incurved valvate estivation. Stamens inserted into the base of the 
perianth, five inner fertile opposite the segments of the perianth, five outer 
sterile, petaloid, usually with glands at their base; anthers ovate, versatile, 
dithecal. Ovary free, two- to three-celled; ovules twin, pendulous; styles 
two to three. distinct or combined; stigmas capitate or obscurely two- 
lobed. Fruit dry, one-, two-, or three-celled. Seeds solitary, pendulous, 
exalbuminous ; embryo thick; cotyledons fleshy; radicle superior. Trees 
or shrubs, with alternate, stipulate leaves, and axillary peduncles, often 
cohering to the petiole. They are natives of the warm parts of Africa and 
South America. The fruit of Chailletia toxicaria is said to be poisonous. 
There are four genera, and ten species known. Examples: Chailletia, 
Tapura. 
OrveER 66. AQuiILARIACEs, the Aquilaria Family. Perianth coriaceous, 
imbricate or tubular, limb four- to five-lobed; sestivation imbricate. 
Stamens usually ten fertile, alternating with ten sterile, in the form of 
petaloid scales, sometimes eight or five; filaments inserted into the orifice 
of the perianth, often united; anthers dithecal, with longitudinal dehiscence. 
Ovary free, ovate, compressed, two-celled; ovules two, suspended, anatropal ; 
stigma usually sessile, large and simple. Fruit a pyriform, sessile, or
