characters of Colletia. Fruit drupaceous, finally coriaceous, dry 

 capsular, surrounded at base to greater or less height with the 

 persistent receptacular cupule and disk ; cocci 3, crustaceous, finally 

 2-valvate. Testa of subereot plano-convex seed coriaceous; micro- 

 pyle in general finally lateral; albumen fleshy; cotyledons of 

 slightly fleshy embryo orbicular or shortly ovate ; radicle very short 

 inferior. — Eamose shrubs, foliate or more rarely leafless; twigs 

 decussate, often spinescent, articulate or subarticulate at nodes ; 

 leaves (small or minute) coriaceous rather thick, imperceptibly 

 pehninerved, oftener obovate, sometimes serrate ; flowers axillary 

 solitary or oftener few cymose ; pedicels waving ; other characters 

 of Colletia} {Trop. alpine and extra-trop. America^ Australia^ New 

 Zealand?) 



35 ? Adolphia Meissn.^ — Flowers nearly of Colletia ; receptacle 

 much shorter subcampanulate, lined with a disk as far as the 

 insertion of petals and stamens. Petals 5, inserted between the 

 3-angular-ovate and recurved lobes of the calyx, small, cucuUate, at 

 base rather longer attenuated subspathulate. Stamens 5, oppositi- 

 petalous and inserted at margin of disk, nearly equal in length 

 to corolla ; anthers small ; cells 2, finally confluent in one above 

 and hence hippocrepiform-rimose. Germen subglobular or at 

 base adnate to receptacular cavity and disk, glabrous; cells 3, 

 1-ovulate ; style slender, 3-lobed at stigmatose apex. Fruit drupa- 

 ceous finally coriaceous subdry subglobular, surrounded at base 

 with the somewhat enlarged and adnate cupule of receptacle, 

 3-coccous ; cocci chartaceous, perforated at the base, finally sepa- 

 rate and dehiscent within. Testa of suberect broadly oblong plano- 

 convex seed coriaceous; albumen fleshy; cotyledons of somewhat 

 fleshy embryo orbicular; radicle short inferior. Other characters
