CAULOPHYLLUM

FIG. 106. Caulophyllum. A, development of fruit and seeds. The seed forces 

 its way through the young pericarp, the latter withers and the seeds mature, 

 becoming globose and deep blue when ripe. B, transverse section of a secon- 

 dary root, showing endodermis (End) with prominent Casparyan Spots; 

 the pericambium made up of a single layer of thin-walled cells (P); a central 

 hadrome on the other side of which is the leptome, each strand of which con- 

 tains a proto-leptome cell (PL). C, transverse section of a secondary root, 

 showing endodermis (End) ; pericambium (P) ; leptome (L) ; tracheae (H) ; and 

 pith (Conj). D, transverse section of a secondary root showing the hyphse of 

 one of the fungi. E and F, transverse sections of a mature stem showing epi- 

 dermis (Ep) ; collenchyma (Coll) ; cells of cortex (C) ; stereome (St) in which 

 occur large secretory ducts (S). G, transverse section of a young stem 

 showing the origin of the secretory ducts; the nature of these has not been 

 determined, although they seem to be characteristic of Caulophyllum. 

 After Holm.
