LECT. VI.] THE STEM. ITS DIVISIONS. 257 



Linnaeus and some others employ the term pro- 

 liferous (prolifer) to denote a modification of 

 the much-branched stem, in which the new 

 branches shoot out only from the summits of 

 the former ones *, as in the Scotch Fir, Pinus 

 sylvestris : but, as Sir J. E. Smith remarks, 

 the term is obsolete, and seldom used. 



c. " Abruptly branched (determinate ra- 

 " mosus), when each branch, after terminating 

 " in flowers, produces a number of fresh shoots, 

 " in a circular order, from 

 " just below the origin of 

 " those flowers ; as in na- 

 " ked- flowered Azalea, Aza- 

 " lea nudiflora, and many 

 " of the Cape Heaths f." 



d. Forked or dichotomous 

 (dichotomus) (fig. i), when 

 the divisions and subdivisions 

 are, throughout, in alternate 

 bifurcations ; as exemplified 

 in Corn Salad, Valeriana 

 locusta, Petty Spurge, Euphorbia peplus, and 



* <c Prolifer ex apicis centre emittens tantum ramos ; 

 " Pinus." Phil. Bot. 82. 28. 



f Smith, from whom this definition is borrowed, says that 

 the term determinate ramosus occurs frequently in the later 

 publications of Linnaeus, particularly the second Mantissa ; but 

 that he has not any where explained its meaning. Introd. p. 122.
