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. |

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. |

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). |

STRUCTURE |
|
A stem-like axis composed of fused leaf bases; esp. in Arecaceae (Palmae), Musaceae. |

apex |
|
Sharply angular; regularly and more or less straightly attenuate to an angular tip, the sides intersecting at an angle of less than 90°. |
|
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 |
|

|
female cone |
= macrostrobilus (not recommended), megastrobilus |
STRUCTURE |
|
A cone (strobilus) whose fertile organs are all megasporophylls. |
|
scabridous |
= rough, scabrate, scabrid, scabrous |
relief |
|
Having small, stout, stiff, more or less acute protrusions. |
|
woolly |
> lanate |
pubescence |
|
Of or bearing relatively long, moderately stout, intertwined, somewhat matted, capillate trichomes. |
|
cleft |
? dissected, divided, lobate, lobed, parted, partite, segmented |
plane shape |
|
Having two or more component sectors or peripheral protrusions that are delimited by concavities in the margin or surface and that are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |
|
oval |
= elliptic(al) |
plane shape |
|
Elongate, widest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |

STRUCTURE |
|
A marginal series or cycle of regular, slender, closely adjacent, more or less flexible segments or protrusions, when treated as an aggregate structure. |
|
sheath (leaf) |
|
STRUCTURE |
|
The lower (basal or proximal), fundamentally laminar but strongly involute portion of one of the non-petiolate leaves characteristic of most monocotyledons (Liliidae); distinct from the leaf blade, which, when present, is borne distally upon it; analogous, though not necessarily homologous, with a petiole; usually more or less completely enclosing a portion of the stem above the node from which the leaf is borne. |
|

= horned |
apex |
|
Bearing one or more cornicula (horns). |
|
perianth tube |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a syntepalous (gamotepalous) perianth proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the tepals. |
