though they still continue to grow afterward. The 
growth of the plant upward is checked by breaking 
off the buds. The Bitter Cassava is the more product- 
ive of the two. The yellowish tubers attain some- 
times a weight of 30 lbs. They do not become soft 
by boiling, like Aipi. 
Maoutia Puya, Weddell.—India, on mountains up 
to 4,000 feet. It is taller than Boehmeria nivea, and 
furnishes a similar fibre. This shrub belongs to a 
tribe of the nettle order, not possessing burning acrid- 
ity. None of the true nettles, such as the Girardini- 
as, nor allied stinging plants, have been recommended 
in this index, although from some an exquisite fiber 
is derived, as the writer wishes to guard against the 
introduction of any burning species, which possibly 
might disseminate itself in a mischievous manner in 
our ranges, and then probably could not be suppressed. 
Maranta arundinacea, L.—The true Arrowroot - 
plant. West India. The plant is introduced into 
this list not without hesitation, as it seems to require 
a warmer clime than ours to attain perfection. It fur- 
nishes most of the genuine West Indian Arrowroot, 
although other species, such as M. nobilis, M. Allouya, 
M. ramosissima, are also cultivated for a similar starch 
of their tubers. 
Matricaria Camomilla, L.—The annual Camo- 
mile. Europe, North and Middle Asia. <A highly 
useful herb in medicine. In many parts of the Eu- 
ropean continent it is much more extensively used 
than the ordinary perennial Camomile. The infu- 
sion of the flowers has rather a pleasant taste, without 
strong bitterness. The flowers serve as a tonic and 
especially as a sudorific, and possess a peculiar volatile
