is also called circimiatus, when we speak of threads and fine 

 tubes. 



The opposite of all the various bendings is plain or eve^i 

 (planus^, (30.) 



VII. Simplicity/, or Composition of the Parts. 



45. 



A part is called simple (simplex), either when it is not di- 

 vided into separate parts, or when it proceeds without inter- 

 ruption ; or, lastly, when it has certain subordinate parts 

 placed only in one row. 



Simple stalks are thus opposed to the branched ; simple 

 lines to those that are articulated ; simple covers, or calyces, 

 to the double or threefold, as also to the scaly.

With respect to composition, we remark the following kinds 

 in the leaves. 



A leaf is said to be compound (compositum), when it con- 

 sists, generally, of several distinct parts, which have a com- 

 mon stalk, or point of insertion. A simple leaf may be 

 deeply lobed, without being on that account compound, pro- 

 vided the substance of the leaf is still united in the base. 

 Hence there are transitions from the folium palmatum, or 

 hand-shaped, to the finger-shaped or digitatum. When two 

 leaves stand together on a common leaf-stalk, they are said to 

 be binate (hinatum), or conjugate (conjugatum), as in the 

 genus Zygophyllum. When three of them stand on a com- 

 mon leaf-stalk, the leaf is said to be ternate (ternatum), as in 

 clover. When there are five, they form the quinate leaf (qui- 

 natum^. When there are seven, they form the septinate 

 leaf (septinatum). The two latter are said to be fingere4 

 (digitatum).
