BORAG1NACE.E. BORAGE TRIBE. 427 



tube of the corolla longer than the calyx ; style longer 

 than the corolla. Parasitic on Heath, Thyme, Milk 

 Vetch, Potentilla, and other small plants, but most 

 abundant on Furze, which it often entirely conceals 

 with tangled masses of red thread-like stems. The 

 flowers are small, light flesh-coloured, and wax-like. 

 Soon after flowering the stems turn dark-brown, and in 

 winter disappear. Fl. August, September. Annual. 



* Other species of Dodder, which more or less resem- 

 ble the preceding species, are C. Europcea (Greater 

 Dodder), which is parasitical on Thistles and Nettles ; 

 C. Epilinum (Flax Dodder), parasitical on Flax, to 

 crops of which it is sometimes very destructive ; C. 

 Hassiaca, parasitical on Lucerne ; and C. Trifolii 

 (Clover Dodder), parasitical on Clover, with the seeds of 

 which it is supposed to have been introduced.

Calyx in 5, rarely 4, deep divisions, not falling off ; 

 corolla of one petal, 5- or rarely 4-cleft, frequently 

 having valves or teeth at the mouth of the tube ; 

 stamens 5, inserted into the corolla and alternate with its 

 lobes ; ovary 4-parted, 4-seeded ; style I, rising from 

 the base of the divided ovary ; fruit consisting of 4, rarely 

 2, nut-like, distinct seeds, each enclosed in a pericarp. 

 Herbs or shrubs with alternate leaves, which are usually 

 covered with hairs or bristles rising from a swollen 

 base. This character was considered by Linnaeus suf- 

 ficiently constant to give to the natural order the name 

 of ASPERIFOLLE, or Rough-leaved plants, but the present 

 name of the order is now preferred as being more com- 

 prehensive, 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 clusters, which are rolled up round the ter-
