 brous above,, rough underneath, with very short scattered stellate hairs. Pe- 

 dicels filiform, often longer than the leaves, although sometimes short. Sepals 

 about 1 line. Petals 1^ lines long. Anthers pale, almost glabrous, not 

 longer than the filaments. Ovary villous or pubescent, with 2 supei-posed

OiiDEn XIV. POLYGALE^. 



Plowers hermaphrodite, irregular. Sepals 5, free, much imbricate, the 3 

 inner ones usually larger and petal-like. Petals 3 or 5, rarely all free, most 

 trequently 2 or 4 in pairs united at the base with the lower concave or helmet- 

 shaped petal or keel and often with the stanunal tube. Stamens 8, rarely 5 or 

 4, usually united to above the middle in a sheath open on the upper side. 

 Anthers erect, 1- or 2-celled, usually opening by a single terminal or oblique 

 pore. Torus small, or rarely expanded into a disk within the stamens. Ovary 

 free, 2-cellcd or rarely 1-celled, or in a few flowers 3- to 5-celled. Style simple, 

 usually curved at the top, with a variously shaped entire or 2-lobed stigina. 

 Ovules usually solitary in each cell, pendulous, anatropons wit.h a ventral 

 raphe. Seeds pendulous, the crustaceous testa often hairy, and bearing a 

 caruncle at the hilum or at the opposite end. Albumen fleshy or rarely defi- 

 cient. Embryo straight, with flat, convex, or rarely thick and fleshy cotyle- 

 dons. — Herbs, undershrubs, or small shrubs, nu'cly (in ^mera or species not 

 Australian) tall shrubs, climbers or trees, glabrous or hairy, but without stel- 

 late hairs. Leaves usually alternate and entire, without stipules, very rarely 

 opposite. Plowers solitary or in spikes or racemes, rarely paniculate, the 

 pedicels usually articulate at the base, with a subtending bract, and 2 brac- 

 teoles, 



A considerable Order, widely dispersed over nearly the whole globe. Of the three Aus- 

 trahan genera, one is the largest and most exteusivel}- diffused of the whole Order, here re- 

 prcbeuted by a very few species of an Asiatic or African type ; another is Asiatic, of which 

 Olid species extends to Australia ; the third is endeiiiic. 



Sepals nearly equal. Anthers 4 or 5. Flowers minute, in terminal 



spikes 1- Salomonia. 



Inner sepals larg:cr and petal-Hke. Anthers 8. 



Capsule ovate or orbicular, scarcely contracted at the base. Seeds not 

 comose. 

 Lateral petals united with the carina (which is always crested in the 



Australian species) , . . - . 2. Polygala. 



Lateral petals aduate to the staminal columu, hut distinct from the 



carina, which is not crested ........•■.•- 3. Comfspfkma, 



Capsule cuueate, very narrow at the base. Seed hairs forming a
