Among exotic genera, Hehinospermum Lappula, a south European 
annual, which has all the appearance and the small flowers of a Myosotis, 
but with triangular, very rough nuts, has been occasionally found in isolated 
localities in England, when accidentally introduced with Continental weeds. 
The well-known sweet Heliotrope of our gardens belongs to a large exotic 
genus, truly Boragineous, though somewhat anomalous in the closer union 
of the nuts. The Nemophilas and Hutocas of our flower-gardens belong 
to the small allied Hydrophyllum family, which has the inflorescence and 
flowers of Boraginea, but the fruit is a capsule, and the leaves often 
divided.

Coarse biennials, or, in exotic species, half-shrubby perennials, with 
blue or purple flowers. Calyx deeply divided. CoroJla with a broad, open 
mouth to the tube, and an oblique limb, with 5 erect or scarcely spreading 
unequal teeth or lobes. Stamens pr otruding from the tube, and unequal 
in length. Style 2-cleft. Nuts wrinkled. 
A rather numerous genus in the Canary Islands and western and southern

—Stem erect, 1 to 2 feet high, covered with stiff, spreading, almost 
prickly hairs. Radical leaves stalked and spreading, but often withered 
away at the time of flowering; the stem-leaves linear-lanceolate, several 
inches long. Flowers showy, at first of a reddish purple, turning after- 
wards bright blue, in numerous one-sided spikes, forming a long terminal 
panicle. Corolla about 7 lines long, the narrow part of the tube about as 
long as the calyx, the limb very-oblique, the longest stamens longer than 
its lower lobes. 
On roadsides and waste places, throughout Europe and western Asia, 
except the extreme north. Dispersed over a great part of Britain, abundant 
in some parts of southern England, but becomes rare in the north; in 
Ireland chiefly near the east coast. Fl. all summer.
