47. COMPOSITACEJE. 
Introduced into Mad. scarcely before 1840, and first noticed 
on the walls of the Rib. de S ia Luzia in Funchal below the 
house of a former British Consul, Mr. Veitch, from whose 
garden, supplied with pi. and seeds occasionally by the Horti- 
cultural Society of London, it was probably thus at first a strag- 
gler ; this pi. had even in 1855 already spread in vast profusion 
over all the neighbourhood of Funchal and elsewhere, even in 
the N. of the island, up to an elevation of 2000 or 3000 ft. or 
more ; forming, in some places, hedges about cottage gardens, 
and in ravines (as up the Rib. de S ta Luzia almost to the foot of 
the great waterfall) thickly clothing the wet dripping perpendi- 
cular cliffs in many places as if perfectly indigenous. Unfortu- 
nately it seems inpplicable to any use but litter, and is entirely 
unfit for fodder. The Portuguese have given it a veiy apposite 
name, “ Inqa muito ,” — equivalent to Spread-much, or literally 
(as applied to insects) Swarm-much. It is originally from 
Mexico and was first brought to England in or about 1830.
