prefix |
|
Indicating presence of or constitution by two entities of the type denoted by the term's stem; as in bicarpellate, biciliate, bifid, bilocular. See also entries for particular terms beginning with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. |

= cartilaginous |
texture |
|
Firm, dense, tough, somewhat pliable, and resilient, like human cartilage. |
|
cone |
= strobilus; > female cone, macrostrobilus (not recommended), male cone, megastrobilus, microstrobilus |

|
A slender stem that grows horizontally upon or just beneath the ground surface, rooting at the nodes and giving rise to erect shoot segments at some nodes and/or at its apex. |
|
fimbria pl. fimbriae |
= fringe |
STRUCTURE |
|
A marginal series or cycle of regular, slender, closely adjacent, more or less flexible divisions or protrusions, when treated as an aggregate structure. |
|
