Gussone in 1842 restored specific rank to S. australis, having in 
the meantime seen specimens of typical S. Lingulata from the Col di 
Tenda (Florae Siculae Synopsis, vol. i. /p. . Subsequent 
writers on Sicilian botany, including Strobl in Flora, 1887, p. 164, 
and Lojacono, Flora Sicula, vol. i. part 2, p. 209, also kept up 
S. australis ; whereas Engler, Monogr. d. Gattung Saxifraga, 1872, 
p- 237, Nyman, Consp. Fl. Eur. p. 267, and Fiori and Paoletti, Fl. 
Anal. Ital. vol. i. 1898, p. 538, who dealt with a wider area, treated 
it as a variety of S. lingulata. 
Sazifraga lantoscana, Boiss. et Reut., was discovered by the 
authors in the Lantosque valley, Alpes Maritimes, and was 
described in Boissier, Diagn. Pl. Nov. ser. 2, No. 2, 1856, p. 63, 
from flowering specimens cultivated in Boissier’s garden at 
Valleyres. : 
Ardoino, Fl. Alp.-Mar. 1867, p. 149, and Rouy, Suites Fl. Fr. 
vol. ii. p. 61, retained S. lantoscana as a distinct species. Engler, 
Monogr. d. Gattung Saxifraga, 1872, p. 237, reduced it to a variety 
of S. lingulata ; and this reduction has been accepted by Nyman, 
Consp. Fl. Eur. 1882, p. 267; Arcangeli, Comp. Fl. Ital. 1882, 
. 255; Ball in Trans. Linn. Soc. ser. 2, vol. v. 1896, p. 160; 
Fiori and Paoletti, Fl. Anal. Ital. vol. i. 1898, p. 538; Rouy and 
Camus, Fl. de France, vol. vii. 1901, p. 79; Burnat, FI. Alpes 
Marit. vol. iii. 1902, p. 260; and Coste, Fl. de France vol. ii. 1903,

* Boissier et Reuter (l.c.) ont caractérisé comme suit la var, 3: 
*‘ Affinis S. lingulatae, Bell., vallis finitimae Tendensis incolae, ab ea 
differt virore minus griseo ad brunneum magis vergenti, foliis supra 
saepius conyexis nec ut in S. dingulata sulcatis, foliis inferne multo 
minus longe attenuatis raroque et obsoleteque acutatis, crusta 
marginali tenuiori et ob paginae superioris convexitatem minus 
icua. M. Engler (l.c.) s’est borné a la diagnose suivante : 
‘Folia brevia, inferne minus longe atténuata, apice non attenuata, 
crusta marginali tenuiori.’ On sépare facilement les échantillons 
typiques de cette variété dont les feuilles subspatulées ou cunéi- 
formes vers leur base ont environ 30 4 40 mm. long., parfois moins, 
sur 5’ 7 mm., parfois 8 mm. de larg., avec un sommet obtus, plus 
ou moins arrondi, rarement acutiuscule, tandis que les échantillons 
de la var. a ont des feuilles plus longues (jusqu’A 11 cm.),
