|
spine |
= thorn |
STRUCTURE |
|
Any sharp, stiff, simple or branched, woody appendage having vascular tissues confluent with those of the bearing structure. "Spine" is often preferred when the appendage is homologous with a leaf or stipule, and "thorn" when it is homologous with a branch. See also prickle. |

inflorescence |
A compound structure belonging to the penultimate subdivisional order of a sedge or grass inflorescence; consisting of one or more florets (each a diminutive flower subtended by specialized bractlets (bracteoles) called scales or glumes in sedges, lemma and palea in grasses), spicately arranged along a common axis (rachilla), the axis and florets together subtended by one or (usually) two bracts (first and second glumes). The spikelet is usually considered to be the basic unit of inflorescence in Cyperaceae and Poaceae (Gramineae). |
