SITUATION AND POSITION OF LEAVES. 145 



as in Paris quadrifolia, t. 7, Polemonium 

 cceruleiun, t. 14, &c. 



Rarnea, branch-leaves, sometimes differ 

 from those of the main stem, and then 

 require to be distinguished from them, 

 as Melampyrum arvense, t. 53. 



Alterna, alternate leaves, stand solitarily 

 on the stem or branches, spreading in 

 different directions, as those of Borage, 

 t. 36, and innumerable other plants. 



Sparsa, scattered irregularly, as in Genista 

 tinctoria, t. 44, Lilium chalcedonicum, 

 Curt. Mag. t. 30, and bulbiferum, t. 36. 



Opposita, opposite to each other, as Saxi- 

 fraga oppositifolia, Engl. Bot. t. 9, 

 Ballot a nigra, t. 46, &c. 



Conferta, clustered, or crowded together, 

 as those of Trientalis europita, t. 15. 



Bina, only two upon a plant or stem, as 

 in the Snowdrop, Galanthus nivalis^ 

 t. 19, Scilla bifolia, t. 24, and Con- 

 vallaria majalis> t. 1035. 



Terna, three together, as Verbena tri- 

 phylla, Curt. Mag. t. 367. The plants 

 of Chili and Peru seem particularly dis- 

 poned to this arrangement oi their leaves.
