bulbil |
= bulblet |
STRUCTURE |
|
A small bulb-like structure produced from a sterile or fertile plant structure other than a bulb, usually within a leaf axil, leaf sinus, or inflorescence, serving as a vegetative propagule. |
endosperm |

STRUCTURE / SUBSTANCE |
|
A genetically triploid (3n chromosomes) nutritive tissue in a seed; containing stored carbohydrate and/or oil utilized by the embryo prior to and especially upon germination; derived from fusion of the two polar nuclei (n + n chromosomes) of the embryo sac with a sperm nucleus from the pollen tube (n chromosomes). See also perisperm. |
resin |
|
SUBSTANCE |
|
A substance of high molecular weight consisting of organic acids, esters, and/or terpenes, produced within plant tissue and exuded from wounds as a liquid that hardens to an amorphous glassy state upon exposure. |
composite |
= compound |
architecture |
|
Unitary as a whole but comprising two or more equivalent substructural entities, these topologically distinct (e.g., leaflets in a compound leaf) or not (e.g., carpels in a compound pistil). |
crista pl. cristae |
= crest |
STRUCTURE |
|
A laterally elongate, relatively thin, irregular or notched, apical protrusion. |
six-… |
= hexa… |
prefix |
|
Indicating presence of or constitution by six entities of the type denoted by the term's stem; as in six-angled, six-sepaled, six-styled. |
hastula pl. hastulae, hastulas |
= ligule misapplied |
STRUCTURE |
|
An outgrowth or enation from the petiole apex at its junction with the adaxial surface of a palmate leaf blade; often woody in texture; variously shaped, its adaxial outline usually resembling an inverted V or U, or a semicircle with the opening proximal; esp. in Arecaceae (Palmae). |
phyllopodium pl. phyllopodia |
|
STRUCTURE |
|
A stem-like axis composed of fused leaf bases; esp. in Arecaceae (Palmae), Musaceae. |
lanciform |
= lancehead-shaped, lanceoloid |
solid shape |
|
Considerably longer than broad, compressed or not, broadest near the base and somewhat concavely attenuate to the apex, the attenuation in all median longitudinal planes or else largely confined to one, depending upon the extent of compression, if any. See also oblanciform (oblanceoloid). |
thrice-… |
= tri…, triple-… |
prefix |
|
Indicating presence of three hierarchical orders of the type of entity or pattern denoted by the term's stem; as in thrice-pinnate. See also three-… (tri…). |
female |
= feminine |
reproduction |
|
Of the sex that produces megaspores and ova. |
scabrid |
= rough, scabrate, scabridous, scabrous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
ostiole |
|
STRUCTURE |
|
The distal aperture of a syconium (fig); in Ficus (Moraceae). |
prolate |
|
plane shape |
|
Symmetrically elongate parallel to the developmental or polar axis. |
botuliform |
= sausage-shaped |
solid shape |
|
Arcuately cylindric with rounded ends. |
ear-shaped |
= auriform |
solid shape |
|
Resembling a mammalian outer ear. |
coating |
|
CHARACTER |
|
Exudate that covers the surface proper. See also indumentum (vesture), pubescence. |
macrophyll (not recommended) |
= leaf, megaphyll; > frond, needle |
STRUCTURE |
|
A principal, vegetative shoot organ borne laterally from a stem node; its vascular tissues, if any, continuous with those of the stem; undergoing no significant secondary growth; usually more or less bilaterally symmetrical; comprising a distal, usually laminar blade and/or a proximal stalk (petiole) or sheath; usually a primary site of photosynthesis. |
friable |
= brittle |
texture |
|
Dry, firm and easily broken. |
sharp |
= acute |
apex |
|
Acutely angular; regularly and more or less straightly attenuate to an angular tip, the sides intersecting at an angle of less than 90°. |
perianth |
|
STRUCTURE |
|
Collectively, all the sterile, primary, lateral organs (tepals, or sepals and/or petals) of a flower; inserted upon the floral axis immediately beneath (proximal to) the reproductive organs (androecium and/or gynoecium) and surrounding them, often protectively; lacking in some taxa; the individual members typically laminar and more or less foliaceous; widely regarded as consisting of the evolutionarily modified leaves of a fertile shoot; the constituent members undifferentiated with respect to one another, or else differentiated into more or less distinct floral envelopes (calyx and corolla), one or the other of which is deemed lacking in some taxa due to evolutionary reduction following differentiation. |
subround |
= subcircular; suborbicular misapplied, subrotund misapplied |
plane shape |
|
Compressed circular or very broadly elliptic, only slightly longer than wide. |
calyx pl. calyces |
|
STRUCTURE |
|
Collectively, the sepals of a flower, whether distinct or connate; the outer or proximal envelope of a differentiated perianth, whether the other envelope (corolla) is also actually present or is deemed to be secondarily absent due to evolutionary reduction. |
knob-shaped |
= gongylodate, gongyloid, knot-shaped, nodiform |
solid shape |
|
Approximately globose, the surface convoluted or not, like a knob or knot; usually applied only to structures or components that are relatively small. |
ten-… |
= deca… |
prefix |
|
Indicating presence of or constitution by ten entities of the type denoted by the term's stem; as in ten-carpeled, ten-stamened, ten-winged. |
