called a Scape (L. stalk). In an inflorescence, when each 

 individual flower has a separate 

 peduncle, this separate peduncle 

 is called a Pedicel. When a 

 pedicel has a bract, this bract is 

 called a Braeteole. Bracts around 

 a solitary flower, or around an 

 inflorescence, form an Involucre; 

 when around a single flower in a 

 cluster (Teasel, Fig. 105), or 

 around a secondary cluster 

 (Parsley, Fig. 139), they form, 

 an Involucel. The calyx-like 

 involucre around the flower in 

 the Mallow, the Cotton (Fig. 

 10), and Pink is called a Calyc- f. 

 ulus. Bracts and their deriva- 

 tives (involucre, spatha, etc.) are 

 often showy and flower-like. an!LVo?s7eS;'T, ft.''"" '^"'""^ ' 



In the Coek's-oomb the anomalous peduncle, enlarged, simulates a 

 crest. In the Venetian Sumach, as it is called (its close cousin 

 is in Alabama), the anomalous pedicles (Fig. 137) are the most con- 

 spicuous part of the inflorescence, and give the tree its varioiis common 

 names, — Wig-tree, Smoke-tree, Mist-tree. The French call it Arbre 



aux perruques — Pow- 

 dered-wig-tree. Few 

 of its flowers are per- 

 fect; the pedicels 

 lengthen, branch, 

 and become finely 

 feathered, giving 

 the large panicles a 

 light, fleecy look.
