CLXXVIII. SCiEVOLEiE. 



GoodenovijE, § Scsevolese, R. Brown Prodr. 582. (1810.) 



Diagnosis. Monopetalous dicotyledons, with a 1-4-celled inferior ovarium, 

 an indusiate stigma, and definite erect seeds. 



Anomalies. A Molucca species of Scaevola exists, with opposite leaves. 

 R. Br. 



Essential Character. — Calyx superior, equal or unequal, in 5 divisions, sometimes 

 obsolete. Corolla superior, monopetalous, more or less irregular, withering - , or deciduous ; 

 its tube split at the back ; its limb 5-parted, with 1 or 2 lips, the edges of the segments being- 

 thinner than the middle, and folded inwards in activation. Stamens 5, distinct, alternate with 

 the segments of the corolla ; anthers distinct or cohering-, 2-celled, bursting- longitudinally ; 

 pollen simple. Ovarium 1- 2- or 4-celled, with 1, seldom 2, erect ovula in each cell ; style 1, 

 simple; stigma fleshy, surrounded by a membranous cup. Fruit inferior, indehiscent, dru- 

 paceous, or nut-like. Seeds with a thickened testa; albumen fleshy, enclosing an erect em- 

 bryo ; cotyledons foliaceous ; plumula. inconspicuous. — Herbaceous plants or sft.ru 6s, without 

 milk, with simple or stellate hairs, if any are present. Leaves scattered, undivided, without 

 stipule. Inflorescence axillary or terminal. Mowers distinct, never capitate, white, blue, or 

 yellowish. 



Affinities. Combined, on account of their indusiate stigmas, by Mr. 

 Brown, with Goodenovia and Brunoniaceee, from the former of which they 

 differ in habit, indehiscent fruit, and definite seeds ; from the latter, in their in- 

 ferior ovarium and habit. 



Geography. Natives of the South Seas and the islands of the Indian 

 archipelago. The species are abundant in New Holland, 



Properties. Unknown. 



Examples. Scaevola, Diaspasis, Dampiera. 



CLXXIX. BRUNONIACEvE. 



Goodenovia, § 2. R. Brown Prodr. 589. (1810.) 



Diagnosis. Monopetalous dicotyledons, with regular flowers, a superior 

 entire ovarium, a single erect ovulum, capitate flowers, and a stigma with an 

 indusium. 



Anomalies. 



Essential Character.— Calyx inferior, in 5 divisions, with 4 bractese at the base. Corolla 

 monopetalous, almost regular, 5-parted, inferior, withering. Stamens definite, hypogynous, 

 alternate with the segments of the corolla ; anthers collateral, slightly cohering. Ovarium 

 1-celled, with a single erect ovulum ; style single ; stigma enclosed in a 2-valved cup. Fruit 

 a membranous utricle enclosed within the indurated tube 6f the calyx. Seed solitary, erect, 

 without albumen ; embryo with plano-convex fleshy cotyledons, and a minute inferior radicle. 

 — Herbaceous plants, without stems, and simple glandless hairs. Leaves radical, entire, with 

 no stipulse. Flowers collected in heads, surrounded by enlarged bracteaj, blue.
