Though differing from Boissier’s character in the colour 
of the petals, which that author describes as rosy, and their 
length, which he states to be only twice that of the sepals, 
this so well agrees not only with the rest of his good de- 
scription, but with native specimens in Munby’s Herbarium 
and others collected by Lefebvre, and communicated by 
Prof. Reichenbach, that I have no doubt of the correctness 
of the identification. As a species it is, as Boissier points 
out, near the widely-diffused G. sylvaticum, but differs in 
being wholly eglandular, with more deeply-divided and silky 
leaves, as also in the woody tuberous rootstock; though 
the latter may well be a climatal character. : 
G. atlanticwm is a native of Algiers, where it is found in 
rocky places, near Constantine by Boissier, on the banks of 
the Chiffa by Munby, on the peak of Mérid by Choulette, 
and in oak forests near Blidah by Lefebvre. The specimen 
here figured flowered in June 1878 and 1879 in the garden 
of the artist, Mrs. Barnard, on Leckhampton Hill near 
Cheltenham, from a root brought by Mrs. Thiselton Dyer 
in 1875 from Algeria.
