Classification of Plants 217 



GG. Fruit i- or few seeded. 



Fruit winged or ribbed ; trees or 



shrubs COMBRETACE^. 



Fruit not winged ; flowers uni- rarely 



bisexual, herbs, in wet places . Haloragidace^. 

 CC. Inflorescence usually an umbel, either 

 racemose or cymose; ovules solitary, 

 pendulous ; seeds endospermous. (Co- 

 hort Umbelliflorae.) . 

 D. Fruit a drupe or berry, 2-4 celled ; 

 trees or shrubs. 

 Leaves alternate, palmate with small 



stipules Araliace^. 



Leaves opposite, penninerved, exsti- 



pulate CoRNACE^. 



DD. Fruit a schizocarp, 2-celled. 



Herbs or shrubs with simple or com- 

 pound leaves, petioles sheathing . Umbellifer^. 



Series H. — Sympetalae. 



Calyx and corolla present, the petals united, rarely free or nearly so. 

 Ovules with a single integument. 



A. Flowers as a rule pentacyclic and isocarpic, 

 i.e. with five floral cycles and number of 

 carpels equal to parts in the other cycles. 

 Floral formula K5, C5, S5 + 5 (in which 

 either whorl may be wanting in some 

 forms), G (5). 

 B. Stamens diplostemonous (twice as many 

 as petals) the outer whorl alternating with 

 the petals or by the suppression of the 

 outer whorl equal to and opposite to the 

 petals, rarely, by branching of the fila- 

 ments, stamens many ; epipetalous. 

 C. Outer whorl of stamens fertile or repre- 

 sented by petaloid staminodia ; placen- 

 tation axile, woody plants with simple 

 leaves. (Cohort Ebenales.) 

 Plants milky, fruit a drupe or berry, seeds 



erect . . . . . . . Sapotace^. 



Plants not milky, seeds hanging, fruit 



a berry Ebenace^. 



CC. Outer stamens absent, inner opposite 

 to petals ; placentation basal or free 

 central. (Cohort Primulales.)
