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. 



Order 64. Samydace.^i;, the Samyda Family. Perianth foux'- to five- 

 divided, usually colored inside ; aestivation 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. Fruit a 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, Avith 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. 



Order 65. Chailletiace.^, the Chailletia Family. Perianth five-parted, 

 with an incurved valvate aestivation. 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-. tAvo-, 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. 



Order 66. Aquilariace^e, the Aquilaria Family. Perianth coriaceous, 

 imbricate or tubular, limb four- to five-lobed ; aestivation imbricate. 

 Stamens usually ten fertile, alternating with ten sterile, in the form oi' 

 petaloid scales, sometimes eight or five ; filaments inserted into the orifice 

 of the perianth, often united ; anthers dithecal, Avith longitudinal dehiscence. 

 Ovary free, ovate, compressed, two-celled ; ovules two, suspended, anatropal ; 

 stigma usually sessile, large and simple. Fruit a pyriform, sessile, or
