Having one or more indistinctly delineated, irregularly shaped, areas of varying size and contrasting hue and/or intensity. |
|
carina 1 pl. carinae |
= keel |
STRUCTURE |
|
An elongate, median longitudinal ridge that is basically triangular in transverse section and resembles the keel of a boat; esp. in leaf blades and sheaths, glumes, lemmata, paleae, sepals, petals. |
|
grooved |
= colpate, fossulate, furrowed, sulcate, valleculate |
architecture |
|
Having one or more relatively narrow and shallow longitudinal depressions (grooves). |
|
spinulose |
|
architecture |
|
Finely spinose. |
|
crest |
= crista |
STRUCTURE |
|
A laterally elongate, relatively thin, irregular or notched, apical protrusion. |
|
barb 1 |
|
STRUCTURE |
|
Any relatively short, stiff, sharp, acutely inserted or bent, antrorse or retrorse, terminal or lateral appendage. |
|
pluri… |
= many-…, multi…, poly… |
prefix |
|
Indicating presence of or constitution by a relatively large number of entities of the type denoted by the term's stem; as in plurilocular, pluriseriate. See also oligo… (few-…). |
|
tartar-like |
= tartareous |
relief |
|
Rough and crumbling spontaneously, becoming erose. |
|
trophophyll |
= sterile frond |
STRUCTURE |
|
A frond that does not bear sporangia; in Polypodiophyta. See also fertile frond. |
|
rough 2 |
= scabrate, scabrid, scabridous, scabrous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
|
anticlinal |
|
orientation |
|
Perpendicular to some given plane of reference; applied especially to the plane of cell division when it is oriented at right angles to the generalized plane of the structural surface. |
|
flexuous var. flexuose |
= zig-zag |
course |
|
Having alternating angular bends to either side, more or less straight between the bends. |
|
obtuse 1 |
= blunt |
apex |
|
Bluntly angular; having an angular tip whose generalized sides intersect at an angle of 90° or more. |
|
climbing root |
< aerial root |
STRUCTURE |
|
An aerial, usually adventitious root that, by some means, serves to anchor a climbing shoot portion to the structure(s) that support(s) it above ground level. |
|
stomate |
= stomatal apparatus, stoma (broad sense) |
STRUCTURE |
|
A localized functional epidermal unit consisting of a microscopic pore and two encircling specialized cells, the guard cells, which, through changes of turgor pressure in response to environmental conditions, regulate the size of the pore and thus the rates of transpiration and gas exchange through it; the whole surrounded or not by associated, cytologically distinctive epidermal cells, the subsidiary or accessory cells, which, when present, are regularly oriented in relation to it. |
|

STRUCTURE |
|
A rudimentary, unexpanded stem, stem branch, inflorescence, inflorescence branch, or flower, or a combination thereof, in a resting state; enveloped or not by subtending protective scales. |
