HYPERICUM UNDULATUM FOUND IN CORNWALL. 219 
spiny point.—New Holland (Ferd. Mueller!).—This is the only form 
known to me from New Holland, and although it differs very much in 
outward look, I can neither separate it by any distinctive characters 
from N. graminea or from the Piedmontese plant described under the 
name of N. Alaganensis, Pollini (1824, under Caulinia), or N. inter- 
media, Nocca and Balbis (1821), and recently illustrated by M. Cesati. 
GENTIANA GERMANICA, Willd. 
In the interesting letter from Dr. Grisebach which we had the plea- 
sure of publishing in March last, he says that the sestivation is not to 
be trusted as a specific character for G. Germanica, as he has seen 
cases of both kinds being found on the same individual plant. Never- 
theless he appears to think that the quincuncial sestivation is the more 
common on that plant. I havé now before me a considerable number 
of fine fresh specimens of G. Germanica, kindly sent by the Rev. H. 
H. Crewe, from Buckland, in Buckinghamshire. I find that most of 
the flowers on these specimens have contorted cestivation, but that one 
flower here and: theré presents the quinéuncial structure, described by 
Grisebach in the ‘Iter Hungaricum,’ as quoted in our page 65 ; but 
I do not find that there is any regularity in the arrangement of the 
flowers, although it is perhaps more usually the terminal flower of the 
stem or a branch that has the quincuncial structure; yet I have seen the 
terminal flower contorted and a lateral flower close to it quincuncial. 
I fully agree with Dr. Grisebach in believing that the estivation is 
here of no value even as a specific character. The ‘ tubo sensim am- 
pliato” of G. Germanica is well seen on these specimens when the 
flowers are expanded. It is truly a funnel-shaped tube, and thus 
differs considerably from the usual nearly cylindrical tube of G. 
Aniarélla.—C. C. BABINGTON. 
HYPERICUM UNDULATUM FOUND IN CORNWALL. 
Mr. James Cunnach, of Helston, Cornwall, has found this plant 
abundantly in bogs near that town. He has known it, but not by
