The plant here figured is one of two closely allied species 
of Acacia, A. spadicigera and A. sphxrocephala, remarkable 
for their enormous horn-like stipules. Both are included 
under Mimosa cornigera, Linn. (Acacia cornigera, Willd.), 
which was founded on the Arbor cornigera of Hernandez, 
** De Historia Plantarum Nove Hispanie”’ (p.86), published 
in 1651, who unfortunately gives no description of the 
plant, only two rude woodcuts of the leaves and stipules, 
with a brief account of the latter forming the home of a 
stinging ant. 
The history of the twin Acacie cornigere is horticulturally 
interesting, one of them having been in cultivation previous 
to 1692, in the Royal Gardens of Hampton Court, under 
the names of the Horn’d Acacia, or Cuckold tree, and of 
which a leafing branch with stipules was figured by Pluke- 
net in the “ Phytographia”’ in 1696, as Acacia Americana 
- + + aculeis cornua bovina referentibus. Plukenet does not 
describe the flowers, but cites Hernandez’ plant as a 
JANUARY Ist, 1895,
