the name of Asperijolice, or Rough-leaved plants ; but the present 

 name of the Order is now preferred as being more comprehensive, 

 a few plants in it having perfectly smooth leaves. The Borage 

 Tribe are natives principally of the temperate regions of the 

 northern hemisphere, especially of the warmer parts, and are more 

 numerous in the Old than the New World. Most of them bear 

 their flowers in spikes or racemes, which are rolled up round the 

 terminal flowers as a centre, and expand a few at a time. The pre- 

 vailing colour is blue or purple, but many, when first opening, are 

 of a reddish hue, which subsequently deepens, so that it is not un- 

 usual to see flowers of different tints on the same spike. They 

 possess no remarkable properties, but abound in a soft mucilaginous 

 juice, which gives a coolness to beverages in which they are steeped, 

 on which account Borage is a constant ingredient in the various 

 forms of drink known as " cup." The roots of Alkanet and some 

 others contain a red substance which is used as a dye. Comfrey 

 (Symphytum officinale) is sometimes grown as an esculent vegetable, 

 but is little valued except as food for horses. The plants of the 

 genus Myosotis are popularly known by the name " Forget-me-not." 

 The true Forget-me-not is M. Palustris. The fragrant Heliotrope, 

 or Cherry-pie, of our gardens belongs to a genus of this Order.
