1. F. Icevis. Sea Heath. A native species with pink flowers, 

 growing in dense patches, and very pretty when in full bloom. 

 There are several other hardy species, none of them very showy. 



OEDEE XVII. CARYOPHYLLE^E. 



Annual or perennial herbs, sometimes woody at the base, 

 often enlarged at the joints. Leaves opposite, entire, with or 

 without stipules. Flowers regular, hermaphrodite, more rarely 

 unisexual by abortion, often in dichotomously branched cymes. 

 Sepals 4 or 5, persistent, free or cohering in a tubular calyx, 

 imbricate. Petals of the same number as the sepals, either 

 hypogynous or perigynous, entire or bifid or fringed. Stamens 

 8 to 10 or fewer, inserted with the petals. Torus usually 

 small. Styles 2 to 5. Capsule 1 -celled, or rarely 2- to 5-celied 

 at the base, membranaceous or crustaceous, dehiscing in valves 

 or at the top, rarely transversely. Seeds numerous, amphi- 

 tropal, albuminous, often reniform, embryo curved. Species 

 very numerous ; especially abundant in the temperate zone of 

 the northern, but extending to the utmost plant limit in the 

 frigid zones of both hemispheres. 



TRIBE I.SILENEJE. 



Sepals united, forming a 4- or 5-lobed tubular calyx. Disk 

 elongated, bearing the petals and stamens. 



1. DLAJSTTHUS. 



The presence of two or more bracts at the base of a tubular 

 calyx and peltate seeds with a straight embryo are the principal 

 distinctive characters. The numerous species are dispersed 

 across Europe, North Africa, and Central Asia, from the borders 

 of the Atlantic to the eastern extremity of China and Japan, 

 and one species is found in North-west America. The species 

 are particularly numerous in the Mediterranean region, and 

 about four extend to Britain. The name is derived from the two 

 Greek words %ios and avOos, literally Jupiter's flower. We 

 must limit ourselves to a review of those species more directly 

 interesting from a horticultural point of view. 



1. D. Caryophyllus. The parent of all the beautiful florist's 

 varieties known under the names of Carnation, Picotee, Clove,
