NATURAL ORDERS ee 
BORAGINACEE. 
The plants belonging to this Order are herbs, with cylin- 
- drical stems and very coarse leaves covered with stiff hairs, so 
that the plants almost sting. This hairiness is very charac- 
teristic of the Order, and is particularly well seen in Viper’s 
Bugloss and Borage. Many of the Boraginacee grow in waste 
places or on roadsides; the hairiness is therefore probably a 
protection against too rapid transpiration (p. 10). 
The Order includes two well-marked groups : 
(a) The Borage group ; 
_ (b) The Hehiotrope group. 
The genera belonging to the former group may again be 
subdivided into : | | 
(i.) Those that have corollas with ligules, as Borage, Com- 
frey, Hound’s-tongue. | 
(ii.) Those in which the corolla has either no ligules, or very 
small ones. To this division belong — 
Viper’s Bugloss, Lungwort, Gromwell, 
and others. | |

peacHstion A rough, hairy plant, 
of growing, unlike most of 
Comfrey. the Boraginaces, on moist 
banks. The lower leaves are stalked, 
the upper ones sessile. 
Inflorescence: a cyme, branching on 
one side only. 
Flower : regular and hypogynous. 
Calyx: 5-cleft, inferior, hairy. 
Corolla : tubular and narrow for half | :

Andrecium: stamens 5, shorter than the petals, epipe- 
talous. 
Gynecium: carpels 2, joined and superior; the ovary is 
4-celled, owing to a bending in of the midrib of each carpel ;
