BOTANY. 129 
ascending ; style simple; stigma simple. Fruit inclosed in the calyx, 
drupaceous, usually unilocular by abortion. Seeds usually solitary, erect, 
or suspended; embryo slender, in the axis of fleshy albumen; cotyledons 
flat, foliaceous ; radicle long, pointing to the hilum. Trees or shrubs, with 
alternate, exstipulate leaves, and frequently stellate hairs. They are 
chiefly natives of warm countries. There are two sections: 1. Styracea, 
with a more or less valvate zstivation of the corolla, and long anthers. 2. 
Symplocée, with a quincuncial corolline estivation, and roundish anthers. 
Lindley gives 6 genera, including 115 species. Examples: Styrax, Halesia, 
Symplocos. | 
Storax, a well-known balsamic, resinous substance, is the concrete juice 
of Styrax officinale, a native of the Mediterranean region. Styrax benzoin, 
a tree growing in Sumatra and Borneo, furnishes gum benzoin. North 
American representatives are species of Halesia or Snow-drop tree, found 
in the southern States.

ditto exposed; d, anthers; e, the pistil; f, section of ovary; g, fruit; h, 
portion of the pericarp removed, showing the stone; 2, the stone with the 
upper portion removed; k, section of seed. 
Orver 107. Cotumenuraces, the Columellia Family. Calyx superior, 
quinquepartite. Corolla rotate, inserted into the calyx, five- to eight-parted ; 
zestivation imbricate. Stamens two, inserted in the throat of the corolla; 
anthers roundish, three-lobed, extrorse, each consisting of six linear, sinuous 
cells, arranged in pairs, dehiscing longitudinally, and attached to a three- 
lobed, fleshy connective. Disk fleshy, perigynous. Ovary adhering to the 
calycine tube, two-celled ; ovules 00; style simple, smooth; stigma capitate, 
two-lobed. Fruit, a bilocular. bivalvular capsule, with both septicidal and 
loculicidal dehiscence. Seeds 00; testa smooth and coriaceous; embryo 
straight, in the axis of fleshy albumen; cotyledons oval, obtuse; radicle 
long, pointing to the hilum. Evergreen shrubs or trees, with opposite, 
entire, exstipulate leaves, and solitary yellow flowers. Natives of Mexico 
and Peru. Their properties unknown. There is one genus mentioned, 
including three species. Example: Columellia. 
Oxver 108. Eracripacea, the Epacris Family. Calyx five-, rarely four- 
parted, often colored, persistent. Corolla inserted at the base of the calyx, 
er hypogynous, deciduous or marcescent, monopetalous, sometimes separable 
into five petals; limb with five, rarely four equal divisions, sometimes by 
the cohesion of the segments bursting transversely ; estivation imbricated 
or valvate. ‘Stamens inserted with or on the corolla, equal in number to, 
and alternate with its segments, rarely fewer; anthers one-celled, without 
appendages, opening longitudinally ; pollen round, or formed of three united 
erains, attached to a single central receptacle. Ovary sessile, free, 
plurilocular, rarely unilocular, surrounded by scales at the base ; ovules 
solitary or 00; style one; stigma simple, sometimes toothed. Fruit 
drupaceous, baccate, or capsular. Seeds albuminous ; embryo slender, in 
the axis of fleshy albumen, and about half its length. Shrubs or small trees, 
‘with alternate, rarely opposite, exstipulate leaves, which are sometimes half-
