the species agree with Dicksoniæ, and also with Balantium 
in the rhizoma or base of the stipes being densely covered 
with long articulated soft fulvous hairs, the appearance of 
which gave rise to the fabulous story of Barometz or the vege-

Observations on the genus HEMYTELIA, of Mr. R. Brown, By 
Grorce Garpner, F.L.S. Professor of Botany and 
Natural History in the Andersonian University, Glasgow. ` 
(With a Plate.—Tab. XII.) 
On my last journey to the summit of the Organ Moun- 
tains, in April, 1841, I found in shady wooded ravines, at 
an elevation of about 6,000 feet, a Tree Fern, from six to 
eight feet high, agreeing with the characters of Hemitelia, as 
given by Presl in his Tentamen Pteridographie, and which 
I imagined might prove to be a new species. Since my 
return to England, I have had an opportunity of comparing 
it with a fine set of specimens of Hemitelia Capensis in the 
Herbarium of Sir William Hooker, from Mund, Harvey, 
Drége and others; and also with individuals in Mr. Brown’s 
Herbarium, collected at the Cape by himself in the year 
1801. A careful comparison proves that the Cape and the 
Brazilian plants are identically the same. 
The genus Hemitelia was first established by Brown in his 
Prodromus Flore Nove Hollandie, in the following observa- 
tions made under the genus Alsophila, at page 158 :—“ Cya- 
thea multiflora Sm., horrida Sm., Capensis Sm., cum aliis 
ineditis, præsertim ab Indià Se, distinctum genus 
efformants a nobis Hemitelia dictum, in quo sori Aiso- 
phile similes, latere vene insident, involucro instructi 
fornicato, basi semicirculari infra receptaculum . inserto, 
marginibus solutis, demum reflexo et persistente.” ` 
Sueceeding authors have adopted the genus, retaining in 
it all the above mentioned species, and others from the
