Collected by Prof. Haussknecht in 1867, on rocks of Mt. Lhahu 

 in Kurdistan. Similar to the preceding, but of a glaucous and 

 more graceful habit ; and differs further in its very small leaves, 

 broader bracts and fuller calyx. 



13. T. rigida Boiss.; L. Sp. Plantarum, ed. 1, p. 408 (Gypso- 

 phila). — Puberula pumila. Caules 13-15 centim. ascendentes 

 corymbose paniculati teretes. Folia subulata acuta margine sca-

This is the veritable Tunica minima of Dalechamps (1513 — 

 1588), described on p. 1191 of his ' Historia,' published the year 

 before his death. Included by Linnaeus in Gypsophila. The 

 Gypsophila rigida figured in the ' Fl. Graeca,' tab. 382, is T. saxifraya. 

 The Tunica of Eupp, in ' Fl. Jenensis,' p. 105 (1718) includes only 

 species now included in Dianthus. 



Bectio IV. Gypsophiloides. — Flores solitarii basi nudi. Calyx 

 tenuiter 5-v. 15-nervius. Polytocnr'.
