without overlapping; 

 iuduplicate, is valvate with the margins of the parts rolled or bent inward; 

 reduplicate is valvate with the margins of the parts rolled or bent outward; 

 contorted or convolute, when each part of the perianth overlaps its neigh- 

 bor all in the same direction, so that one edge of each part is exterior 

 and the other edge is interior or overlapped.

 two others by both its margins.

 toward the pistil; extrorse, with the line of dehiscence toward the corolla. 

 Apex: free termination of a leaf or its segments. It may be acuminate, long and 

 tapering; cuspidate, abruptly contracted to a sharp point; mucronate,
