Orpver XXIII. CARYOPHYLLACEA.—CiLoveworts. 
Herbs, with the stems swelling at the nodes. 
Lvs. opposite, entire, destitute of stipules. Fils. regular. 
Cal.—Sepals 4—5, distinct, or cohering in a tube, persistent. _ : 
Cor.—Petals 4—5, (sometimes none) either unguiculate and inserted upon the pedicel of the ovary, or 
without claws and inserted on the outside of a fleshy disk. 
Sta. twice as many as the petals, rarely equal or few; anthers introrse. 
Ova. often stipitate. Styles stigmatose the whole length of their inner surface. 
Fr. a 1-celled capsule or imperfectly 2—5-celled, opening at the apex by twice as many teeth as there are 
stigmas. Seeds numerous. 
Genera 53, species 1055. Elevenofthe genera are North American, the remainder ate found in the 
temperate and frigid climates of the Eastern Continent. Properties unimportant. The order is noticeable 
chiefly for the beauty of a few of the cultivated species.
