|
oil-secreting |
|
exudation |
|
Producing and exuding an oily substance, often aromatic; when oil-secreting glands are indicated in the nominative, often they are called simply oil glands. |
|
tuberous 1 |
|
architecture |
plant |
Bearing tubers. |
|
discal |
|
insertion |
|
Upon or otherwise directly associated with the floral disc. |
|
pseudolamina pl. pseudolaminae |
|
STRUCTURE |
|
The expanded part of a phyllode (phyllodium), resembling a blade but evolutionarily derived from the petiole. |
|
coherent |
|
fusion |
equivalent structures |
Joined superficially, with no significant histological continuity. |
|
included |
|
position |
anther, style |
Not protruding beyond the floral envelope. See also exsert(ed). |
|
papilla pl. papillae |
|
FEATURE |
|
A small, conoidal protrusion resembling a pimple. See also pustule (blister, bulla). |
|
septate 2 |
|
architecture |
trichome |
Unicellular to multicellular with transverse partitions (septa) that are common cell walls (intercellular) and/or intrusions from longitudinal cell walls (intracellular). |
|
pyramidal |
|
solid shape |
|
Transversely triangular or polygonal, broadest at the base and regularly attenuate to an angular apex, all faces essentially plane. |
|
submergent |
|
location |
structure of aquatic plant |
Descending from above the water surface to a point beneath it. |
|
concolor(ous) |
|
coloration |
|
Uniform in hue and intensity of color; esp. leaves with identically colored adaxial and abaxial surfaces. |
|
bud scale |
|
STRUCTURE |
|
A scale that, alone or aggregated with others, envelops and protects a bud. |
|
insertion |
|
CHARACTER |
|
Mode or locus of attachment of a structure to some dissimilar bearing structure. The lexicons relating to insertion and position overlap to a great degree, since these two morphological concepts are often inseparable in practice. Also overlaps conceptually with arrangement, habit, orientation, and shape. |
|
elastic |
|
texture |
|
Resiliently deformable with no loss of structural integrity. |
|
androdioecious |
|
reproduction |
taxon |
Having some plants with only bisexual flowers and others only staminate ones. |
|
microspore |
|
STRUCTURE |
|
A male spore; a spore of the smaller of the two types produced by the sporophytes of a heterosporous taxon; produced in a microsporangium; giving rise upon germination to a microgametophyte. |
|
rank |
|
FEATURE |
|
A sequence of lateral structures arising from the same axis at successive points along its length and diverging from it in the same direction. |
|
superaxillary |
|
insertion |
|
Internodal but close to and directly above the axil(s). |
|
calyptrate |
|
architecture |
|
Having or constituting a calyptra. |
|
isostemonous |
|
architecture |
flower, androecium |
Having the stamens essentially alike in size and shape. |
|
persistent |
|
duration |
structure |
Remaining attached and conspicuous until the bearing structure reaches maturity. |
|
smooth 1 |
|
relief |
|
Even or unrelieved overall. Strictly applied, this term refers only to the surface proper; however, it is often used to mean glabrous as well. |
|
antheridium pl. antheridia |
|
STRUCTURE |
|
A male gametangium; a multicellular fertile organ of a mature gametophyte within which male gametes (antherozoids, spermatozoids) are produced and from which they are discharged, in some taxa forcibly, through a pore. Technically present but highly reduced and of no descriptive significance in Magnoliophyta and part of Pinophyta. |
|
glochidiate |
|
pubescence |
|
Bearing glochids (glochidia). |
|
mucro pl. mucrones, mucros |
|
STRUCTURE |
|
A short, hard, apical point that is a continuation of vascular tissue. See also apiculum. |
