The Heliotrope which we figure is a native of South- 
eastern Brazil, Uruguay and Buenos Ayres. It bears a 
strong general resemblance to the Sweet-scented Heliotrope, 
H. peruvianum, Linn., figured long ago at t. 141 of this 
work, but is readily distinguished from its fragrant 
Peruvian congener by having odourless flowers. The 
species has long been known in gardens both in Europe and 
in North America, and we learn from Gray that it has 
become subspontaneous in Eastern Florida and often appears 
as a ballast weed about Philadelphia. The earliest descrip- 
tion, which we owe to Poiret, appeared in 1813; in 1829 
it was more fully described, apparently from South Brazil 
specimens of Sellow’s collecting, by Chamisso. There has 
never been any confusion between HH. anchusaefolium and 
fT, peruvianum, whether in herbaria or in gardens. But 
there has been, and still often is, both among horticulturists 
and botanists, a tendency to confuse with Poiret’s plant 
that described by Sir W. J. Hooker at t. 3096 of this work 
as Tournefortia heliotropioides. The two plants are, how- 
ever, specifically quite distinct, for that described by Hooker 
has broad elliptic leaves with petioles three-quarters of an
