polygalacej:. 35 



Herbs, undershrubs, or slirubs, with flowers variable in colour, 

 in racemes, spikes, or heads, which are terminal or lateral. 



The generic name is derived from ttoXw {j>oly), much, and yaXa (gala), mOk, alluding 

 to the reputed eflects of the plant on the cattle that feed on it. 



SPECIES I.— POLYGALA VULGARIS. Linn. 

 Plates CLXXXV. CLXXXVI. CLXXXVII. 

 Eootstock producing numerous stems, and much branched, 

 especially at the base. Leaves of the base of the stems ovate, those 

 of the flowering shoots generally elliptical or lanceolate, becoming 

 gradually longer than those below, which are not collected into a 

 rosette at the base of the shoot. Calyx wings with the nerves 

 rather conspicuous, the central nerve almost unbranched to near 

 the apex, where it gives off branches which anastomose with the 

 lateral nerves, which have numerous anastomosing branches on the 

 outer side ; or rarely the lateral veins anastomose directly with the 

 central one. Strophiole of the seed with the lobes unequal, the 

 lateral ones about one-thu-d the length of the seed.

Stems woody and procumbent at the base, and then usually 

 ascending or erect, rather stiff, much branched near the base ; the 

 flowering shoots never umbellate. Leaves ascending, scattered 

 throughout, but more crowded below ; upper ones lanceolate. 

 Racemes many-flowered, terminal. Central bract about as long 

 as the pedicel when the flowers are fully expanded.

Branches erect or ascending, straight. Eacemes 10- to 20-

 Pedicels glabrous. Margin of the bracts, calyx wings, petals, and 

 capsule not ciliated.
