Order XXIII. HYPERICACE^. 

 By J. M. Coulter, 



Herbs or shrubs with opposite entire leaves dotted with pellucid spots or dark 

 glands, and no stipules. Flowers perfect, regular, hypogynous, solitary or 

 cymose. Sepals 4 or 5, imbricated in bud, herbaceous and persistent. Petals 

 4 or 5, mostly convolute in bud, deciduous, and yellow or flesh-color. Stamens 

 usually numerous and 3- or 5-adelphous, occasionally with alternating glands ; 

 anthers 2-celled, longitudinally dehiscent, mostly versatile. Carpels 2 to 5, 

 united to form a 1-celled or more or less perfectly 3-5-celled ovary, which 

 contains numerous anatropous ovules ; styles as many as the carpels, slender, 

 distinct or more or less united. Fruit (in ours) a septicidal capsule ; seeds exal- 

 buminous ; embryo usually straight. — A small order, but represented in all 

 temperate and warmer regions. Its close relationship to Guttiferce has suggested 

 its inclusion in that order, from which it differs in its often herbaceous habit, 

 comparatively thin leaves, perfect flowers, and filiform styles. 

 1. ASCYRUM. Sepals 4, very unequal, the outer pair very broad, the inner much smaller. 



Petals 4, very deciduous. Stamens numerous, distinct or slightly united at base, with no
