acicular 2 |
= acerose, needle-shaped |
solid shape |
|
Rounded in cross-section and very slenderly elongate, broadest near the middle, and gradually attenuate to an acute apex and a slightly blunter base; like a needle. |

solid shape |
|
Gradually diminishing in width or diameter from one end to the other. |
|
depressed |
< flattened |
solid shape |
|
Flattened distally, perpendicular to the longitudinal axis, as though pressed from the top, the external surface otherwise basically convex. Often used in combination with some other term that describes the overall shape exclusive of ("before") flattening, e.g., depressed-globose. See also compressed (complanate), obcompressed. |
|
epipetalous |
|
position |
|
Upon the petals, or partially adnate thereto and apparently arising therefrom. |
|
intercostal |
|
position |
|
Between the costae. |
|
bi… 2 |
= double-…, twice-… |
prefix |
|
Indicating presence of two hierarchical orders of the type of entity or pattern denoted by the term's stem; as in bicrenate, bipinnate. 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. |
|
furrow |
= colpus, fossula, groove, sulcus, vallecula |
FEATURE |
|
An elongate depression that is relatively shallow and narrow. |
|
stoma 2 (strict sense) pl. stomata |
= stomatal pore |
FEATURE |
|
The aperture between and regulated by the two guard cells of a stomate (stomatal apparatus). |
|
nodule |
|
STRUCTURE |
|
A small nodiform (gongylodate, gongyloid, knob-shaped, knot-shaped) segment or protrusion; esp. in roots of Fabaceae (Leguminosae) and harboring nitrogen-fixing bacteria. |
|
punctiform |
= dot-like |
plane shape |
|
Very small and generally circular in outline. |
|
vascular |
|
insertion |
|
Upon or otherwise directly associated with the vasculature. |
|
firm |
|
texture |
|
Yielding under only moderately strong pressure; only slightly deformable without internal structural disruption. |
|
leaf scar |
|
FEATURE |
|
A scar on a twig or stem due to abscission of a megaphyll; having an outline like that of a transverse section through the base of the petiole, sheath, or blade that was inserted there. |
|
parchment-like |
= pergamentaceous |
texture |
|
Very thin, pliable, and fairly tough; like parchment. See also chartaceous (papery, papyraceous), membranaceous (membranous). |
|
barbel |
= barbella |
STRUCTURE |
|
A small barb. |
|
campanulate |
= bell-shaped |
solid shape |
|
Circular in transverse section, inflated proximally, thence broadening gradually to a flared distal portion. |
|
hard |
= indurate(d) |
texture |
|
Yielding only under strong pressure; not deformable without internal structural disruption. See also callose (callous), hard-coated (corticate), hard-stemmed (sclerocaulous). |
|
surficial |
= superficial |
insertion |
|
Directly upon the surface of the structure in point. |
|
concave-tapered 2 |
= attenuate |
base |
|
Gradually diminishing in width or diameter toward the proximal end, the sides longitudinally concave. Corresponds with acuminate for apex shape. |
|
embryo sac |
< megagametophyte |
STRUCTURE |
|
The multinucleate generative cell of an ovule, within which fertilization and zygote formation occur; resulting from meiotic division of a megaspore mother cell within the nucellus, and thus genetically haploid; its contents generally considered to represent an evolutionarily reduced gametophyte. |
|
rhombate |
= rhombic |
plane shape |
|
Broadest at the middle and more or less regularly attenuate to either end, the sides angled at the middle and more or less straight from there to either end. |
|
indehiscent |
|
dehiscence |
|
Not splitting or forming an aperture at maturity, the contents being released for dispersal only after decay, digestion, or erosion of the structure. |
|
trigonous |
= three-angled, triquetrous; > deltoid, obdeltoid |
solid shape |
|
Elongate with three sides that meet at acute or obtuse angles. |
