Examination of the material in the Kew herbarium confirms the 
result arrived at by Burnat and other authorities, that it is best to 
treat S. lantoscana and S. australis as varieties of S. lingulata. 
Owing to the large number of intermediate forms it is difficult to 
divide S. lingulata (in the broad sense) into varieties, and it is quite 
probable that different results might be arrived at from the study 
of different herbaria. As a basis for future work, however, it may 
be well to state the conclusions arrived at from the study of the 
Kew material, which includes a fine series of specimens forming 
part of the Churchill herbarium, which was bequeathed to Kew in 
1906 (see Kew Bull. 1906, p. 387). 
Four more or less distinct races may be recognized. The first 
(fig. 1) is typical S. lingulata, Bellardi (var. Bellardii, Sternberg). 
This is characterized by numerous long linear acute leaves, 
channelled on the upper surface, with a conspicuous calcareous 
incrustation. It appears to be all but confined to the Italian part 
the Alpes Maritimes, and ave seen no specimens except 
in the Kew herbarium by a co-type, collected by Bellardi and 
distributed in Dickson’s Collection of Dried Plants, No. 63, as 
S. callosa, Smith. 
The second race corresponds to S. australis, Moric. (S. lingulata, 
var. australis, Engl.). It appears to vary considerably in the shape 
and size of the leaves according to situation, and is accordingly 
difficult to define. Well-grown plants from lower altitudes (fig. 2) 
have long broadly linear or linear-spathulate leaves, nearly flat on 
the upper surface.’ Specimens from higher altitudes have short 
broadly spathulate leaves, resembling those of Jantoscana, but 
broader. The distribution of S. australis is as follows, according 
to the Kew material :—Mountains of Carrara and Massa, Pistojan 
Apennines, Monte Majella and Monte Morrone in Abruzzo, 
mountains near Latronico in Basilicata, and the mountains of 
Northern Sicily. It is probably this race of S. lingulata which 
has been discovered recently in Calabria (Longo in Ann. di Bot. 
Roma, vol. i. 1903, p. 98). 
There are no Sardinian specimens of S. lingulata in the Kew 
herbarium but the figure given by Moris, Fl. Sard. t. 74, suggests 
that the Sardinian A belongs to S. australis. This is the view 
taken by Nyman, Consp. FI. Eur. p. 267, who gives the distribution 
of S. australis as Southern Italy, Sicily and Sardinia,
