Chronological Sequence of the Species. 



Linnean species. — Tbree of tbe species included in this Synopsis 

 were described by Linnaeus, each of which is to be found under a 

 different genus. 



Gypsophila riyida (1753) = T. rigicla Boiss. 



Dianthus saxifrayus (1753) = T. saxifraga Scop. 



Saponaria Ulyrica (1767) = T. Ulyrica Fisch. et Mey. 

 The post-Linnean species up to 1824. — Six species belong to this 

 period ; they include : — 



T. compressa (1798) of Algeria. 



T. graminea (1806). Neither described nor figured afterwards in 

 the ' Fl. Graeca ' with the next three species. 



T. dianthoides, cretica, and ochroleuca, in the 'Fl. Graeca' (1823). 



T. armerioides (1824) of Anatolia. 



From this date to the completion of Boissier's ' Diagnoses ' 

 (1859). — During this period eleven more species were described; 

 they are : — 



T. striata (1830), in Central Asia. 



T. pachyyona (1837), in Western Asia. 



T. fasciculata (1841). Transferred from Saponaria by Boissier 

 in « Suppl. Fl. Orient.' (1889). 



T. Gasparrini and T. brachypetala (1842). 



T. thessala, syriaca, Sibtlwrpii, and hispidula ; described in the 

 first series of Boissier's 'Diagnoses' (1849). 



T. Orphanidesiana, from Mt. Parnassus (1855).

From 1860 to the present year seven species have been added : — 



T. arenicola (1860). 



T. Haynaldiana (1870). 



T. Peronini, macra, and phthiotica, described in Boissier's
