500 to 2000 feet above the sea, as A, maciilatum, L., is in Engkud ; occurring 
in precisely similar situations, viz. moist shady banks, under walls and hedges 
by roadsides, and in damp sheltered places all over the island, flowering from 
March to May. It is, therefore, doubtless the plant intended by Professor O. 
Heer, under the name of A. Italicum. Indeed, till I met with Webb's de* 
scription (in January, 1857) of his A. Canarlense^{P\i^iQgv, iii. 293, 294) I had 
been content to refer the Madeirau plant to A, Italicum^ Mill., as a form, or 
at most a mere variety, — an opinion which is indeed somewhat more disturbed, 
but not entirely removed, by the liigh authority of Dr. Schott. Tlie plant is 
called in Madeira Bigaloa or Blgallioay and arrowroot is occasionally prepared 
from its corms. It is justly accounted a troublesome and noxious weed, and 
^QT^ diiBcult of extirpation.

MEMORANDA. 
Calltina VuxGARib IN Newfotjndlawd. — Mr. Murray, late of the Geolo- 
gical Survey of Canada, and now engaged in a sui'vey of JVewfoundland, lias 
brought to Montreal specimens of this plant, which were collected by Ju^lge 
Bobinson on the east coast of ^Newfoundland, near Ferryland (lut. 47", long. 
52^ 5(y), and which are stated to be from a small patch of the plant not more 
than three yards square. Tiie locality is in the same part of the island to 
■which the specimens collected hj a Mr. Gormacfc {or M'Cormack), and for- 
merly in the collection of the Linnean Society, are referred (Joum. Bot., Vol. II- 
p. 55), namely, the south-east peninsula 5 and two additional localities m thia 
peninsula are noticed in Cormack's label, namely, the head of St. Mary's Bay 
and Trepassy Bay or Harbour. It is supposed that the Conuack who collected 
these specimens is the wcU-kuown explorer of the interior of Newfoundland ;
