OBSERVATIONS ON HOLL'S LIST. 29 
The sugar used commonly in Madera is, and ever was, im- 
ported almost entirely from Lisbon (a little being only occa- 
sionaly introduced from London, or direct from Brazil,) not 
exclusively by the English; and it all comes originaly from 
the Brazils. 
* Carex muricata, Linn." The very common Carex of 
Madera is certainly C. divulsa, Good. ; but according to Pro- 
fessor Henslow's observations, it may nevertheless be also 
rightly named by Mr. Hóll. Imust observe, however, that I 
have never been able to discover the least tendency in the 
Madera plant, which abounds everywhere, to depart from 
the form of C. divulsa, and approach to that of C. muricata. 
** Gladiolus Byzantinus, Mill.” Had Mr. Holl procured this 
plant in flower, he would have discovered it to be not G. 
Byzantinus, Mill., but G. segetum, Ker, in Bot. Mag. t. 719, 
(G. communis, Sm. in Fl. Gr., not Linn.) On account of 
the thin pulp surrounding the kernel of the seed beneath the 
spermoderm, this plant was afterwards referred by Mr. Ker 
to Antholyza. By others it has been distinguished, on account 
of this character and the subglobose shape of the seeds, 
as a genus; under the somewhat inappropriate name of 
Spherospora. 
* Amaryllis Belladonna, Linn.” Not by any means local, 
as Mr. Héll’s observation would imply, but abounding every- 
where in the Chestnut woods. Inthe north, I have witnessed 
whole acres in the woods completely covered in October 
with its lovely flowers; a scene exceeding in beauty even the 
dreams of poets. 
“ Dioscorea sativa, Linn.” The plant here intended is, 
without a doubt, my Tamus or Tamnus edulis. See Camb. 
Trs. The true D. sativa, L., I have nowhere seen in the 
Island; but D. alata, L., is still perhaps existing in one or 
two gardens, though merely as an object of curiosity. 
* Allium Cepa, Linn.," has no more title to a place inthe 
Madera Flora than in a Flora of Germany, France, or Eng- 
land. : 
* Dracena Draco, Linn." The “wood” of D. Draco,
