170 ENGLISH BOTAXr. 



I am indebted to Mr. Wilkinson of Scarborough for a fine series of 

 fresh specimens of this plant from the Forge Valley station. 



Two-leaved Smilacina. 



German, ZweihliUtrige Scliattenhluine. 



GENUS III.—P OLYGONATUM. Toumef. 



Perianth tubular-cylindrical, clavate, coloured, deciduous; limb 

 ■with G minute suberect or spreading-ascending teeth at the apex. 

 Stamens 6, inserted in the middle of the perianth tube, included ; 

 anthers rather long. Ovary free, sessile, 3-celled ; ovules 2 to 6 

 in each cell ; style slender ; stigma subcapitate, obscurely 3-lobed. 

 Berry globose, 3- to 6-seeded. Seeds subglobose ; testa thin, pale or 

 fuscous. 



Herbs with thick creeping rhizomes, and simple erect or arching 

 leafy stems. Leaves sessile, usually alternate, rarely opposite or ver- 

 ticillate, striate. Flowers rather large, greenish-white (rarely pink), 

 drooping, on axillary 1- or few-flowered peduncles. 



The name of this genus is derived from the Greek words iro\u£, many, and 

 yivv, angle or joint, from the many joints of the rootstock.
