apex of a twig {EtdUicium) solitary or few cymose {North America,

5. Drimys Forst. — Flowers hermaphrodite or polygamous. Calyx 

 gamopliyllous sacciform or cupiiliform membranous valvate, at 

 authesis irregularly cleft or breaking open. Petals 2-ao spirally 

 imbricated in oo whorls. Stamens ao in a spiral on a cylindrical 

 receptacle ; filaments free rather thick ; anther-cells extrorse parallel 

 or diverging dehiscing longitudinally. Carpels l-oo (usually few) 

 pseudo-verticillate free, ovaries with oo oblique or transverse ovules 

 in two vertical rows; style short, apex dilated stigmatiferous. 

 Fruit simple or more frequently multiple ; carpels indehiscent many- 

 seeded. — Evergreen trees or shrubs ; leaves alternate exstipulate 

 with pellucid dots. Flowers cymose, either axillary or lateral to 

 branches a year old or older {Eudrini^s), or in the axils of leaves or 

 bracts on younger twigs ; cymes simple or branched, more rarely 

 1 -flowered {South America, Neio Zealand, Australia, Borneo). See 

 p. 151. 



6. Zygogynum H. Bn. — Flowers hermaphrodite ; peduncle 

 dilated around base of receptacle into a short orbicular subentire 

 cupule (calyx?). Petals (?) few unequal concave thick imbricate 

 deciduous. Stamens go {oi Drimj/s). Carpels oo arranged in a spiral, 

 cohering into a single oo-ceUed ovary ; ovaries oo-ovulate ; ovules 

 oblique in two vertical rows on inner angle ; styles short distinct, 

 apex capitate stigmatiferous. Fruit syncarpous. . . . — Small ever- 

 green tree ; leaves alternate exstipulate dotted ; flowers solitary 

 terminal; peduncle thick articulated at base {Neio-Caledonia). See 

 p. 156. 



IV. EUPTELEEiE. 



7. Euptelea Sieb. & Zucc. — Flowers polygamous. Receptacle 

 somewhat concave. Perianth 0. Stamens co sHghtly perigynous. 

 Filaments free, shortly fihform, anthers basifixed, apiculate ; cells 

 adnate, lateral dehiscing longitudinally. Carpels co stipitate, inserted 

 in a nearly simple verticil in the bottom of the receptacle ; ovary 

 1-cellcd; ovules 1—4 inserted on the ventral angle, obliquely 

 descending, micropyle extrorse superior, or horizontal or sub-
