BERMUDIAN FERNS 
By tHe Rev. Roserr Honter. 
Ina ee, of wild plants made between 2nd August, feat 
and 7th May, 1865, by me in Bermuda, ten ferns occur. These w 
kindly named a si years ago by Mr. Baker, F.L.S., of Kew. 
came too late for his edition of Sir William Hooker's “ Synopsis Fili- 
cum (1874), and as only one of the ten, Acrostichum aureum, is formally 
mentioned in that standard work as growing in Bermuda, their publi- 
“sna even at this remote date may not be without interest.

ON SOME HYBRID BRAMBLES. 
By Dr. W. O. Fock. 
Occurren in the study of the nearly inextricable ir pacuaage of 
European Rubi, I have endeavoured to obtain by diff 
idea of the true relationship between the innumerable ae goa 
j ow 
hybridisation might be capable of accounting for the numerous 
it 2 es between the links of the whole 
group. I think that a series of pee st ments will in the end enable us 
_ to answer the question, and I have made an amy to take the first 
steps in this directi 
ion. 
Amongst the ——. Rubi there are three closely allied forms, 
viz., R. bifrons, Vest., R. villicaulis, Koebl., and 2. gratus, dis- 
tinguished by me some yearsago. They belong to the group of Valli- 
caules, and have arcuate, angulate, more or less hairy stems without 
aciculi or sete, rooting in autumn at the ends. ‘The stamens are 
longer aa the pistils, and after flowering bend together and cover 
In R. gratus the stem is decidedly angulate, t 
i and moderately strong, the leaves digitato-quinate, the 
rome hairy and green on both sides, the inflorescence rather lax and 
leafy with scattered short prickles, the sepals in the fruit spreading or
