210 NATURAL HISTORY OF PLANTS. 



curtails); calyx valvate or slightly imbricated, 3 -partite, Gynse- 

 ceum as in Mercurialis. Germen cells 3, alternating with sepals, 1- 

 ovulate; style branches liaear-lanceolate, stigmatiferous within. 

 Capsule 3-coccous; seeds subglobose scantily arUlate. — Humble 

 herbs prostrate thin-stemmed scandent ; leaves alternate membrane- 

 ous, crenate-dentate or lobed, 2 -stipulate ;^ flowers axillary with rudi- 

 mentary twigs ; male solitary or few ; female solitary, finally much 

 longer pedunculate.^ (Chili^ Equatorial Andes, Magellan Alps, 

 Island of J. Fernandez ^). 



66. Mercurialis T,* — Flowers monoecious or dioecious, apetalous, 

 usually 3-merous ; male calyx valvate. Stamens definite {Trisme- 

 gista^ A8'e2'c?e&^), alternating with sepals (2, 3) or subindeflnite, 

 usually 00 {Linozosiis^ Claoxylon,^ Erythrococca ^ ) ; filaments cen- 

 tral free inserted on rather convex receptacle ; anther cells 2, rimose, 

 free, from the first ( Claoxylon) or more or less late erect ; sometimes 

 but rarely adnate to the connective [Seidelia, Adenoclme). Glands or 

 Qo (possibly glanduliform staminodes ?) inserted on receptacle usually 

 exterior to fertile stamens. Female calyx valvate or slightly 

 imbricated. Germen 2-3-locular ; cells 1-ovulate ; style branches 

 same in number, papillose stigmatiferous within. Glands of hypo- 

 gynous disk alternating with germen cells and equal in number to 

 them, either linear (Idnosotis) or more or less widely squamiform, 

 sometimes very small ( Claoxylon). Fruit 2-3-coccous ; seeds thinly 

 arillate at micropyle or more rarely on both sides. — Herbs or under- 

 shrubs sometimes small shrubs (Erythrococca), shrubs or trees
