CLASSIFICATION. 



the ^ pistil. Carpels 2 combined into a 2-or 1- celled ovary or 

 distinct except in the styles. Ovules many parietal or covering 

 a large axile placenta. 



Exceptions : — 



Stipnlee or stipular lines sometimes occur in Loganiacese, and L. some- 

 times toothed in Buddleia. Fls. irregular in a few GentianaceaB and 

 stamens fewer than the petals. 



CoroUa often imbricate or valvate in Loganiaceae. 



Ovules only 2-8 in each cell in a few Apocynaceae. 



72. Th3 Strychnine Family. 



Trees, shrubs or herbs with sometimes stipnlar lines. Jnice 

 not milky. Cymes usually dense. Calyx 4-5-toothed. Ovary 

 2-celled. Pr. dehiscent or indehiscent. 



72. Loganiacese (p. 419). 



73. The Gentian Family. 



Kerbs. Jnice not milky. Fls. 4-5'merous, often showy 

 in dichasial cymes. If irregular, fls. small and stamens 

 reduced in number. Ovary 1-celled with parietal placenta- 

 tion, rarely placentaa meeting, and ovary 2-celled. 



73. GentianaceaB (p. 420). 



74. The Oleander Family. 



Trees, shrubs or herbs, often climbing, abounding in milky 

 juice, with opp, or whorled leaves. Calyx 5-lobed. Corolla 5- 

 lobed, rotate or salver-shaped, often with a corona. St. with 

 their anthers rarely distant, usually conniving, and sometimes 

 adhering by a point of the connective to the swollen base of 

 the stigma. Ovary 2-celled, or of two distinct carpels connate 

 in the style. Fruit baccate, drupaceous or of follicles. Seeds 

 often with a coma of hairs. 74. ApooynaceaB (p. 423). 



75. The Asclepias or Mudar Family. 



Climbing herbs, rarely erect shrubs, abounding in milky 

 juice (with very few exceptions), rarely leafless (Sar- 

 costemma) differing from the apocarpous Apocynacece essen- 

 tially in the pollen, which forms one or two waxy, more rarely
