obtriangular 2 |
= cuneate, wedge-shaped |
plane shape |

Inversely triangular; like the outline of the broad lateral face of a wedge, broadest at the apex. See also obdeltate. |
stoma 1 (broad sense) pl. stomata |
= stomatal apparatus, stomate |
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. |
puncticulate |
= small-dotted |
coloration |
|
Finely punctate (dotted). |
cartilaginous |
= cartilage-like |
texture |
|
Firm, dense, tough, somewhat pliable, and resilient, like human cartilage. |
membranous |
= membranaceous |
texture |
|
Extremely thin, pliable, and fairly tough; like animal membrane. See also chartaceous (papery, papyraceous), pergamentaceous (parchment-like). |
…segmented |
? …cleft, …fid, …lobate, …lobed, …parted, …partite |
solid shape |

Having the number of segments indicated by the prefix; as in ten-segmented. |
…angled |
= …gonous |
solid shape |
|
Elongate with the number of longitudinal angles indicated by the prefix, the intervening sides transversely flat or curved; as in four-angled. See also …angular (…gonal), deltoid, obdeltoid, triquetrous. |
paraphysis pl. paraphyses |
|
STRUCTURE |
|
An elongate, multicellular, sterile structure borne between sporangia within a sorus; in Polypodiophyta. |
supramedial |
|
position |
|
Just above the middle of the structure in point. |
rhizome |
= rootstock |
STRUCTURE |
|
An underground, usually horizontal stem, often superficially resembling a root but easily distinguished by the presence of nodes, from which it branches exogenously to produce the aboveground portion(s) of the shoot. |
bent |
= flexed |
solid shape |
|
Having an abrupt bend at some point along its length. See also declinate (inclinate), geniculate (kneed), inflexed, reflexed. |

architecture |
|
Lacking stomates in the epidermis. |
headed 2 |
= capitate |
solid shape |
|
Abruptly enlarged distally to a relatively short, terminal portion that is basically round in transverse section. |
staminodial |
|
position |
|
Upon or otherwise directly associated with the staminodes. |
