pubescence |
|
Of or bearing relatively short, slender, soft, more or less erect, capillate trichomes. See also puberulent. This is one of the most ambiguous terms in the botanical lexicon; it should not be used unless its intended meaning is explicit. |
|
megagametophyte |

PLANT |
|
A gametophyte whose fertile organs (gametangia) are all archegonia. |
|
flanged |
|
solid shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |
|
ventral (not recommended) |
= adaxial |
position |
|
On or pertaining to the side or portion of a lateral structure that faces (or would face) toward the bearing axis when (or if) the axis of the lateral structure is (or were) oriented in the same general direction as the bearing axis. |
|
papillar(y) |
= papilliform |
solid shape |
|
Small, conoidal, and protruding from a larger structure; resembling a pimple; esp. trichomes. |
|
sperm |
> antherozoid, spermatozoid |
STRUCTURE |
|
A male gamete. |
|
awn |
= arista, bristle, seta |
STRUCTURE |
|
A slender, more or less straight and stiff, fine-pointed, terminal or subterminal appendage or prolongation, sometimes a continuation of the bearing structure's central primary vein, as on a glume, lemma, or palea in Poaceae (Gramineae). |
|
retrorse |
|
orientation |
|
Directed generally backward, toward the proximal end of the context of reference, parallel or at an acute angle to the bearing structure. |
|
ala 1 pl. alae |
= wing |
STRUCTURE |
|
Any elongate, relatively thin protrusion or appendage. |
|
nodal |
> interpetiolar |
insertion |
|
Upon or associated with the nodes. |
|
small-sawtoothed |
= serrulate |
margin |
|
Finely sawtoothed (serrate). See also scalloped (crenate), small-scalloped (crenulate), small-toothed (denticulate), toothed (dentate). |
|
headless 2 |
= acephalous |
solid shape |
|
Not terminating in a head-like portion, esp. when one might be expected. |
|
crested |
= cristate |
apex |
|
Having a laterally elongate, relatively thin, irregular or notched protrusion. |
|
pinnatifid |
> pinnatisect; < pinnate |
solid shape |
|
Pinnately divided. |
|
sterile frond |
= trophophyll |
STRUCTURE |
|
A frond that does not bear sporangia; in Polypodiophyta. See also fertile frond. |
|
diamond-shaped |
= rhomboid |
solid shape |
|
Transversely square, broadest and longitudinally angular at the middle, regularly attenuate to angular ends, all faces essentially plane; like the stylized shape of a diamond. |
|
laticiferous |
|
exudation |
|
Producing and exuding latex. |
|
branch |
|
STRUCTURE |
|
Any higher-order division of or outgrowth from an axis, vein or veinlet when such division or outgrowth is equivalent in nature to the structure of origin. |
|
fibrous |
|
texture |
|
Having tough, woody or sclerotic strands distributed through a softer matrix. |
|
scale-like |
= squamiform |
solid shape |
|
Isodiametric to elongate in broad outline, relatively very thin, and planate to moderately concave-convex. |
|
ovule |
|
STRUCTURE |
|
A complex reproductive structure borne by a seed-plant sporophyte, consisting of outer, sporophytic tissues that enclose a haploid, gametogenic tissue usually regarded as a highly reduced megagametophyte. Following fertilization, the entire structure matures to become a seed that contains an embryo, the first stage of the next sporophytic generation. Ovules (and seeds) are borne naked on megasporophylls (in Pinophyta) or within an ovary (in Magnoliophyta). |
|
inclined |
= declined |
orientation |
|
Directed downward or backward. |
|
prophyll(um) pl. prophylls, prophylla |
= bracteole, bractlet; < bract |
STRUCTURE |
|
