442 GOODENIACE.E STYLIDIACE^E. 



erect, exalbuminous; embryo straight; cotyledons fleshy, plano- 

 convex; radicle minute, inferior. Stemless herbaceous plants, with 

 radical, exstipulate leaves, and capitate flowers, supported on scapes, 

 and surrounded by an involucre of enlarged bracts. Natives of New 

 Holland. Their properties are unknown. The order contains as yet 

 only 1 genus, and 9 species. Example Brunonia, 



920. Order 108. Goodeniacete, the Goodenia Family. (Monopet. 

 Epigyn. and Perigyn.) Calyx persistent, usually equal, with 3-5 divi- 

 sions, sometimes obsolete. Corolla inserted into the calyx, monopeta- 

 lous, 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 5-partite, uni- or 

 bilabiate, the thin part of the segments being at the edges, which are 

 folded inwards in aestivation. Stamens 5, distinct, inserted with, but 

 free from, the corolla, and alternate with its segments; anthers not 

 articulated with the filaments, distinct or cohering, bilocular, with longi- 

 tudinal dehiscence; pollen-grains either separate or united in fours. 

 Ovary more or less united to the calycine tube, 1-2- or 4-celled, some- 

 times with a gland at its base; ovules definite or 00, attached to a 

 central, often free, placenta; style 1, simple, rarely divided; stigma 

 fleshy, undivided or 2-lobed, surrounded by a cup-like indusium. 

 Fruit a 1-2- or 4-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. Some are eaten 

 as pot-herbs. The order is divided into two suborders: 1. Good- 

 enieae, with dehiscent capsular fruit, and numerous seeds. 2. Scaevoleas, 

 with indehiscent, drupaceous, or nut-like fruit, and seeds solitary, or 

 two in each cell. There are 14 known genera, according to Lindley, 

 and about 150 species. Examples Goodenia, Velleia, Leschenaultia, 

 Sc83vola, Dampiera. 



921. Order 109. Styiidiacere, the Stylidium or Stylewort Family. 

 (Monopet. Epigyn.) Calyx adherent, persistent, with 2-6 divisions, 

 bilabiate, or regular. Corolla gamopetalous, falling off late, limb 

 usually irregular, 5-6-partite, segments with a central vein; aestivation 

 imbricated. Stamens 2 ; filaments united with the style into a longi- 

 tudinal 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 1; stigma entire or bifid. Fruit a bivalvular, bilo- 

 cular, or spuriously unilocular capsule, with septicidal dehiscence. 

 Seeds 00, small, erect; embryo minute, enclosed in fleshy, somewhat
