46 NATURAL HISTORY OF PLANTS. 



connected with the Saholacccc. He enumerated besides, Ggrostemonea 

 in connexion with the Phytolaccacca? ; they were ranged after the 

 THupJiorbiacea by Lindlky, 1 who distinguished into two very 

 different orders the Petweriacece 2 {Petiveria, Seguieria, Gatlesid), 

 and the Phyfotaccacece, 3 to which he joined the genus Stegnosperma, 

 recently established by Bentham. 4 Moquin-Tandon, who in 

 1S49 formed the first complete monography of the group Phyto- 

 laccacece? divided it into eight tribes : Seguieriea, which are the 

 Petiveriacea of Lindley ; Rivinea, comprising, besides Rivina and 

 Mohtana, the genus Ledenbergia of Klotszch ; 6 Microtea (with the 

 single genus Microtea) ; Limece, which comprises, besides Limeum 

 (and Semonvillea) the Anisomeria of Don ; 7 the Gisechiece, of which 

 Giseckia is the type, and by which it is connected with Phytolacca, 

 Pircuma and Ercitta ; the Stegnospermea (Stegnosperma) ; Gyros- 

 temoncce, formed of different genera united by us to Gyrostemon 

 (Codonocarpus, 8 Cyclotheca), and of Didymotheca f and Tcrsonicce, 

 represented by the single genus Tersonia. Since then we have 

 connected 10 with Phytolaccacece, as the type of a special series, the 

 Barbeuia of Dupetit-Thouars, 11 doubtfully attributed to Rosacea. 12 

 The Agdestis of Sesse and Mocinno has been indicated 13 as belonging 

 to the Phytolaccacece, where it forms a special series on account of 

 the form of its receptacle and its inferior ovary ; and the ancient 

 genus Thelygonum has appeared to us, not without some doubt, capable 

 of being connected as the title of a distinct series with the Phyto- 

 laccacece with unicarpellary gynseceum, like the Rivinacece. Thus we 

 find assembled in this small family eighteen genera grouped in six 

 series and comprising about seventy-five species. All those, eight 

 or nine in number, which constitute the Gyrostemon series are Austra- 

 lian. It has also the only known species of the genus Monococcus. To 

 America belong exclusively all the Ercillas, Anisomerias, Agdestidece,
