Geography. Natives of New Holland, and other islands of the South 

 Pacific Ocean. 



Properties. Unknown. 



Examples. Goodenia, Velleia, Leschenaultia. 



. CLXXVII. STYLIDIE^e. 



STYLiDEiE, R. Brown Prodr. 565. (1810). 



Diagnosis. Monopetalous gynandrous dicotyledons. 

 Anomalies. 



Essential Character Calyx superior, with from 2 to G divisions, bilabiate or 



regular, persistent. Corolla monopetalous, falling off late ; its limb irregular, rarely 

 regular, with from 5 to 6 divisions, imbricated in {estivation. Stamens 2 ; filaments con- 

 nate with the style into a longitudinal column ; anthers twin, sometimes simple, lying over 

 the stigma ; pollen globose, simple, sometimes angular. Ovarium 2-celled, many. seeded, 

 sometimes 1 -celled, in consequence of the contraction of the dissepiment, often surmounted 

 with a single gland in front, or two opposite ones ; style 1 ; stigma entire or bifid. Capsule 

 with 2 valves and 2 cells, the dissepiment between which being sometimes either contracted 

 or separable from the inflexed margins of the valves, the capsule becomes as it were 1 -celled. 

 Seeds small, erect, sometimes stalked, attached to the axis of the dissepim'ent ; embryo 

 minute, enclosed within a fleshy, somewhat oily albumen — Herbaceous plants or nnder- 

 shrubs, without milk, having a stem or scape, their hair, where they have any, simple, 

 acute,' or headed with a gland. Leaves scattered, sometimes whorled, entire, their mar- 

 gins naked or ciliated, the radical ones clustered in the species with scapes. Flowers in 

 spikes, racemes, or corymbs, or solitary ; terminal, rarely axillary, the pedicels usually 

 with three bracteaj. 



Affinities. Nearly allied both to Campanulacese and Goodenovige, 

 from both which they are distinguished by their gynandrous stamens, and 

 from the latter by the want of an indusium to the stigma. The structure 

 of the sexual organs is highly curious ; the stamens and style are closely 

 combined in a solid irritable column, at the top of which is a cavity, in- 

 cluding the stigma, and bounded by the anthers. A singular blunder was 

 committed by Labillardiere, who mistook the epigynous gland for the stigma: 

 and another by L. C. Richard, who considered the labellum to be the female 

 organ. 



Geography. Chiefly found in New Holland. Species have been dis- 

 covered both in Ceylon and the South Sea Islands. 



Properties. Unknown. 



Examples. Stylidium, Forstera. 



CLXXVIII. SC^yOLE^. 



GooDENOViyE, § Scaevolese, R. Broivn Prodr. 582. (1810). 



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

 rium, an indusiate stigma, and definite erect seeds. 



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

Essential Character — Calyx superior, equal or unequal, in 5 divisions, some- 

 times obsolete. Corolla superior, monopetalous, more or less irregular, withering, or deci- 

 duous; 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 ?estivation. 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
