time during research for several days, if looked for outside the 
basin. I lost much time by not being sooner aware of this 
Circumstance. 
The shrubs which are most abundant in the Caldeira are 
Erica scoparia, Juniperus (species unascertained), Myrsine 
retusa, Laurus Canariensis, and Vaccinium Maderense (or pa- 
difolium). Though the flowers of this Vaccinium are much 
longer than those of the Madeira specimens, I am disposed 
to regard the Azorean plant as the same species; not detect- 
ing any other well marked difference. Viburnum Tinus, He- 
dera (Heli ?), Ilex Perado, and a handsome shrubby Eu- 
Phorbia, also occur among the more abundant species first 
named. This EupAorbia is nearly allied to E. mellifera, but 
Is much larger in all its parts, and more especially in its 
leaves. It grows like a great forked candelabrum, with long 
and stiff branches, which terminate in tufts of darkly glau- 
Cus leaves and umbels of yellow flowers. 
Among the Ferns, as far as my recollection serves, the 
most conspicuous for their size or frequency were Wood- 
. wardia radicans, Pteris arguta, and aquilina, Aspidium fæ- 
msecii, and angulare:—Trichomanes speciosum, Hymenophyllum 
 *Unöridgense, Cystea fragilis, Acrostichum squamosum, and 
ng ium monanthemum, though less conspicuous, were 
-Plentiful enough in many places, on wet and shady rocks.
