 calyx.) D. C. prod. 1. p. 351. Caryophylleae, Lam. Sepals 

 grown together into a cylindrical or campanulate tube, 4 or 5- 

 toothed at the apex. 



I. GYPSO'PHILA (from yi/^oe, gypsos, lime, or plaster, and 

 ^J\EW, phileo, to love ; because the plants of this genus chiefly 

 prefer a limestone or chalky soil.) Lin. gen. no. 768. D. C. prod. 

 1. p. 351. 



LIN. SYST. DecdniJria, Digynia. Calyx campanulate, angu- 

 lar, somewhat 5-lobed ; margins of lobes membranous. Petals

 posed in diffuse panicles. 



SECT. I. STRU'THIUM (Struthium is the Latin for fullers'herb.) 

 Ser. mss. and D. C. prod. 1. p. 352. Calyxes free from scales 

 at the base. 



1 G. OCCELLA'TA (Sibth. et Smith, fl. graec. t. 387.) flowers 

 capitate ; petals ovate, marked by a purple circle ; stems diffuse ; 

 leaves spatulate, downy on both surfaces. If. . H. Native of 

 mount Delphi in the island of Negropont. Cucubalus poly- 

 gonoides, Willd. spec. 2. p. 690 1 Petals entire, white, marked 

 with a purple circle as in Di&nthus delloides. Stems diffuse, 3

2 G. THYMipbuA (Sibth. et Smith, fl. grsec. t. 388.) flowers 

 somewhat capitate ; stems diffuse, somewhat dichotomotis ; leaves 

 spatulate, downy on both surfaces ; petals obovate, rounded, 

 not spotted. If. . H. Native of mount Parnassus. Habit of 

 G. occellata. Stem more elongated and more branched. Calyx 

 hairy. Flowers 2 or 3 in each tuft, white. Plant diffuse.

 nearly semi-cylindrical, axillary ones crowded. If. . H. Native 

 of Spain. Barrel, icon. 64. t. 119. Stems shrubby at the base. 

 Flowers white. Petals hardly emarginate. This herb is said 

 to be used instead of soap for scouring by the Spaniards at pre- 

 sent, as it was by the ancients. It would be curious to know if 

 the plant contains fossil-alkali, like many succulent maritime 

 plants, and whether the saponaceous qualities of Saponaria offi- 

 cinalis be owing to the same cause.
