BOTANY. 173 
stipulate leaves, found in New Holland, and not possessing any marked 
properties. Lindley notices two genera and ten species. Example: 
Stackhousia. 
Sub-class 4. Thalaméflore. 
Calyx and corolla present; petals distinct, inserted into the thalamus or 
receptacle; stamens hypogynous. This includes the hypogynous polypeta- 
lous orders of Jussieu, and a diclinous order (Menispermaceze). Sometimes 
the petals are abortive, and it is then difficult to determine whether the 
plant belongs to this sub-class, or to Monochlamydee. 
Orper 162. Cortartace®, the Coriaria Family. Flowers unisexual. 
Calyx campanulate, five-parted ; sestivation imbricate. Petals alternate 
with the calycine segments, very small, fleshy, with a keel on the internal 
surface. Stamens ten; filaments filiform, distinct ; anthers dithecal, oblong. 
Ovary composed usually of five carpels, attached to a thickened receptacle 
or gynobase, five-celled; ovules solitary, pendulous ; style 0; stigmas five, 
long and glandular. Fruit, consisting of five monospermous, indehiscent, 
crustaceous carpels, inclosed by the enlarged petals. Seeds pendulous, 
anatropal, exalbuminous; embryo nearly straight ; cotyledons fleshy ; 
radicle short and blunt. Shrubs with opposite square branches, opposite, 
simple, ribbed leaves, and scaly buds. They are found in small numbers in 
the south of Europe, South America, India, and New Zealand. Some 
of them are poisonous. Eight species of the single genus Coriaria are 
known. 
OrvEer 163. Ocunacrea, the Ochna Family. Sepals five, persistent, 
imbricated in estivation. Petals equal to, or twice as many as the sepals, 
deciduous, spreading, imbricated in estivation. Stamens five, opposite the 
sepals, or ten, or indefinite; filaments persistent, attached to a hypogynous 
disk ; anthers bilocular, innate, opening by pores, or longitudinally. Carpels 
as many as the petals, seated on an enlarged gynobase (thecaphore): ovule 
erect or pendulous, styles united into one. Fruit gynobasic, consisting of 
several succulent, indehiscent, monospermous carpels. Seeds anatropal, 
usually exalbuminous ; embryo straight; radicle short ; cotyledons thick. 
Undershrubs or trees, with alternate, simple, stipulate leaves, and pedicels 
articulated in the middle. They grow in tropical countries, and are 
remarkable for the large succulent prolongation of the receptacle to which 
the carpels are attached. They are generally bitter, and some of them are 
used as tonics. Lindley enumerates six genera, comprehending eighty-two 
species. Examples: Ochna, Gomphia, *Castela. This order is represented 
in North America by a single species, Castela nicholsonii. 
Orver 164. Smrarupaces, the Quassia and Simaruba Family. Flowers © 
usually hermaphrodite. Calyx in four or five divisions; stivation 
imbricated. Petals four or five, spreading or connivent into a kind of tube; 
eestivation twisted. Stamens twice as many as the petals; filaments 
arising from scales. Ovary four- or five-lobed, four- or five-celled, supported 
on a gynophore ; ovules solitary ; style simple; stigma four- or five-lobed.
