STRUCTURE |
|
Any sterile structure deemed to represent a modified pistil, homology being inferred on the basis of structural similarity, ontogeny, and/or position; sometimes nectariferous, sometimes connate with others or adnate to other floral structures. |
|
pistillodium pl. pistillodia |
= pistillode |
STRUCTURE |
|

Having a more or less tubular, radially or bilaterally symmetrical body closed at the base and broadening toward a more or less open apex sometimes lidded or overarched by a prolongation of one side; like a pitcher. |
|
pith |
|
STRUCTURE |
|
The central ground tissue of a stem or, when present, of a root, consisting of thin-walled parenchyma cells; distinct and more or less soft and spongy relative to the other tissues of the axis; sometimes partly or wholly degenerating after secondary growth has begun. |
