1& TRUNKS. 



V. Form. 



Besides being occasionally ROUND, ANGULAR, &c* 

 the peduncle is termed 



1. FILIFORM, (Jiliformis) thread shaped, when it is 

 of slender structure like a thread. 



2. ATTENUATED, (atteuuatus) diminishing insensi- 

 bly in thickness from the base to the summit. 



3. lNCRAssATED,(mcrassato) thickening at the sum- 

 mit ; opposed to the last. Ex. Annual Sunflower, Hell- 

 anthus animus. 



VI. Length. 



1. SHORT, (ftrms) very little shorter than the 

 flower. 



2. VERY SHORT, (brevissiinus) much shorter than the 

 flower. 



3. EQUAL, (inediocris) of the length of the flower. 



4. LONG, (longus) somewhat longer than the flower. 



5. VERY LONG, (longissimus) more than twice the 

 length of the flower. Thornton. 



Observation. 1. Linnaeus very rarely admits ar.y other mensura- 

 tion than that arising- from the respective length* and breadth of 

 the parts of a plant compared with each other ; of which the above 

 is an example. 



2. Instead of using terms like the above, which would be liable 

 to mislead, authors express themselves more fully thus Peduncle 

 shorter than the flower as loner as the flower longer than the flower 

 ttoice as long as the flower, &c. 



5. Petiole. 



PETIOLE, (petidus) Leaf-stalk or Foot-stalk. A 

 species of trunk bearing the leaf only. 



Observation. 1. The peduncle and petiole were called by Lin- 

 nscus partial trunks, feeing" placed upon the general or universal 

 trunk, which proceeds immediately from the root. 



2. The petiole is commonly channelled on its upper side. The 

 channel ends in a concavity at the base on the side next the stem, 

 "#lnch is termed the AXILLA.
