Orper 113. Sryutpraces, the Stylewort Family. Calyx adherent, 
persistent, with two to six divisions, bilabiate, or regular. Corolla gamo- 
petalous, falling off late, limb usually irregular, five- to six-partite, segments 
with a central vein; estivation imbricated. Stamens two; filaments 
united with the style into a longitudinal column; anthers didymous, rarely 
simple, lying over the stigma; pollen simple, globose, or angular. Ovary 
cohering with the calyx, bilocular, or by contraction of the dissepiment 
unilocular, often surmounted by one gland in front, or by two opposite ones ; 
ovules anatropal; style one; stigma entire or bifid. Fruit a bivalvular, 
bilocular, or spuriously unilocular capsule, with septicidal dehiscence. 
Seeds 00, small, erect; embryo minute, inclosed in fleshy, somewhat oily 
albumen. Non-lactescent herbs or undershrubs, with alternate, scattered, 
or somewhat verticillate, entire, exstipulate leaves. They are well distin- 
suished by their gynandrous structure. The column formed by the union 
of the filaments and style possesses, in the species of the genus Stylidium, 
a peculiar irritability. The plants are principally natives of marshy places 
in New Holland. Some are found at the southern point of South America. 
There are five known genera, and 121 species. Examples: Stylidium, 
Forstera. 
Orver 114. Goopentacea, the Goodenia Family. Calyx persistent, 
usually equal, with three to five divisions, sometimes obsolete. Corolla 
inserted into the calyx, monopetalous, more or less irregular, marcescent or 
deciduous; its tube split at the back, and sometimes separable into five 
pieces, when the calyx only coheres with the base of the ovary ; its limb 
five-partite, uni- or bilabiate, the thin part of the segments being at the 
edges, which are folded inwards in estivation. Stamens five, distinct, 
inserted with, but free from, the corolla, and alternate with its segments : 
anthers not articulated with the filaments, distinct or cohering, bilocular, 
with longitudinal dehiscence; pollen grains either separate or united in 
fours. Ovary more or less united to the calycine tube, one-, two-, or four- 
celled, sometimes with a gland at its base; ovules definite or 00, attached 
to a central, often free, placenta; style one, simple, rarely divided ; stigma 
fleshy, undivided or two-lobed, surrounded by a cup-like indusium. Fruit a 
one-, two-, or four-celled capsule, or drupaceous or nut-like. Seeds definite 
or indefinite, with a thickened, often hard testa; embryo straight, in fleshy 
albumen ; cotyledons leafy ; radicle inferior. Herbs, rarely shrubs, not 
lactescent, with scattered, exstipulate, usually alternate leaves, and distinct, 
never capitate flowers. They are found chiefly in Australia, and in the 
South Sea Islands. The order is divided into two sub-orders. 
Sub-order 1. Goodeniee, with dehiscent capsular fruit, and numerous seeds. 
Sub-order 2. Scevolee, with indehiscent, drupaceous, or nut-like fruit, and 
seeds solitary, or two in each cell. There are fourteen known genera, 
according to Lindley, and about 150 species. Examples : Goodenia, Velleia, 
Leschenaultia, Sczevola, Dampiera. 
Orver 115. Brunonracea&, the Brunonia Family. Calyx persistent, five-
