or THE FLOWER-STALK. 129 



scales become leafy, and render the Sea- 

 pus a proper Caulk. 



The Stalk is spiral in Cyclamen, Engl. 

 Bot. t. 548, and Valisneria spiralis, a won- 

 derful plant, whose history will be detailed 

 hereafter. 



Linnaeus believed * that a plant could 

 not be increased by its Scapus, which in ge- 

 neral is correct, but we have already re- 

 corded an exception, p. 112, in Lachenalia 

 tricolor. The same great author has ob- 

 served -f that " a Scapus is only a species of 

 Pedunculns." The term might therefore be 

 spared, were it not found very commodious 

 in constructing neat specific definitions of 

 plants. If abolished, Pedunculus radicalism 

 a radical flower-stalk, should be substituted 

 in its room. 



4. Pedunculus, the Flower-stalk, springs 

 from the stem, and bears the flowers and 

 fruit, not the leaves. Pedicellus, a par- 

 tial flower-stalk, is the ultimate subdivision 

 of a general one, as in the Cowslip, and 

 Saxifraga umbrosa, E/igL Bot. t. 6G3.
