by natives. Twelve 



Stamens 4 (the lower pair longer), anthers 

 2-celled. Upper lip of the corolla 

 spreading, lower longer. Herbs or 

 shrubs with a disagreeable odour. 



Leonotis. — Calyx 10 - toothed, 

 upper tooth larger. Corolla densely 

 hairy, tube much longer than the 

 calyx ; upper lip long, curved, lower 

 short, spreading, 3-lobed. Stamens 4. 

 Anthers in pairs, 2-celled. Herbs or 

 half shrubs, with bright scarlet or 

 orange flowers. L. Leonorus, R. Br.

Order Bor.vgin.^ce.?;. 



The deeply 4-parted ovary and the more or less irregular 

 flower, suggests the order Labiatea:. The flowers of this order 

 are not so distinctly 2-lipped. The leaves are usually alternate, 

 the stem round, and often succulent, and the strong odour of 

 the Labiatece is lacking. Stamens 5, epipetalous. The flowers 

 are arranged in a coiled cyme, which straightens as it lengthens. 

 Stem and leaves frequently rough with hairs. Fruit of four 

 separable nuts, or a berry. Seeds erect, basal as in Labiata;, but 

 radicle points upwards. 



Calyx 5 -parted, sepals lance-shaped. 



Lobostemon. — Corolla more or less zygomorphic, funnel- 

 shaped. Stamens joined at about the middle of the corolla, 

 each provided at base with a hairy bordered scale, which 

 protects the honey from short-tongued insects. Fruit of four 

 nuts. Herbs or shrubs with rough leaves and showy pink, 

 purple, or blue flowers. 



Echium is similar 10 LoluiitcDion. The stamens have no 

 scale at base, but its bristly calyx would discourage ants. 



Myosotis (Forget-me-not). — Corolla regular; tube closed
