economical point of view, producing the common arrowroot of 
commerce. I obtained my specimens from Mons. Linden, of 
Brussels, who procured them from Kio Bianco. It requires the 
temperature of a moist stove, and grows vigorous^ in any rich 
light soil, if allowed plenty of pot room, and be supplied with 
water liberally during the growing season. It is increased by 
dividing the roots. — IF. W. S.
