308 THE BORAGE FAMILY. 
tube of the corolla, and alternating with its divisions. Ovary 
deeply 4-lobed (or, in some exotic genera, 2-lobed), with a simple 
style inserted between the lobes. Fruit consisting of as many 
small, l-seeded nuts, having the appearance of seeds, and en- 
closed within or surrounded by the calyx. , 
A numerous family in the northern hemisphere, with a few represen- 
tatives in the tropics or in the southern hemisphere; easily distinguished 
by the 4 seed-like nuts from all but Zabiatew, and from these by their 
alternate leaves and more regular flowers. 
Tube of the corolla open, without any scales or valves at its 
orifice. 
Stamens protruding beyond the corolla. 
Corolla oblique and more or less irregular, with erect, or 
scarcely spreading lobes . 1. ECHIUM. 
Corolla regular, with a straight tube and spreading limb 3. MERTENSIA. 
Stamens included in the tube of the corolla. 
Calyx tubular, the lobes not reaching to the middle 2. PULMONARIA. 
Calyx divided to the base. Nuts very hard . 4, LITHOPSERMUM, 
Tube or centre of the corolla more or less closed at its orifice 
by seales or valves, or stamens. 
Corolla tubular, with 5 smallteeth . : 8. SYMPHYTUM. 
Corolla rotate, the anthers erect, forming a cone in the 
centre 9. BoRAGO. 
Corolla (small) with a slightly bent tube, and rather oblique, 
spreading limb 7. LycopslIs. 
Corolla with a straight tube, ‘and regular spreading limb. 
Calyx broad, and somewhat flattened, enlarged after flower- 
ing, with small teeth between the large ones . . . 10. ASPERUGO, 
Calyx regularly 5-cleft. 
Nuts depressed, ovate or round, muricated and burr-like. 11. CyNoGLossumM. 
Nuts ovoid, erect, srnooth or wrinkled. 
Nuts wrinkled. Spikes with a bract under each flower. 6. ANOCHUSA, 
Nuts smooth and shining. Racemes without bracts. 
Flowers usually small . ’ ‘ ; 4 . 5, MYOoSsOoTIs, 
Among exotic genera, EA Hea) a hg 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 
Eutocas of our flower-gardens belong to the small allied Hydrophyllum 
family, which has the inflorescence and flowers of Boraginec, but the 
fruit is a capsule, and the leaves often divided. _ 
I. ECHIUM. ECHIUM: 
Coarse biennials, or, in exotic species, half-shrubby perennials, with 
blue or purple flowers. Calyx deeply divided. Corolla with a broad, 
open mouth to the tube, and an oblique limb, with 5 erect or scarcely 
spreading unequal teeth or lobes. Stamens protruding from the tube, 
and unequal in length. Style 2-cleft. Nuts wrinkled. 
A rather numerous genus in the Canary Islands and western and — 
southern Africa, with a few European and west Asiatic species, |
