arrangement |
|
Disposed along the axis in the number of distinct ranks indicated by the prefix; as in two-ranked. |

epicotyl |
= plumule |
STRUCTURE |
|
A distinguishable nascent shoot developed in the embryo in some taxa, consisting of a shoot axis with unexpanded internodes and one or more leaf primordia, being that portion of the embryo above the level of cotyledon insertion; the primordial shoot, when developed by the embryo within a seed; the first bud of a spermatophyte, when developed by an embryo within the seed. In other taxa the shoot is represented in the embryo only by a quiescent apical meristem at the summit of the embryonic axis. |

|
leaf 2 pl. leaves |
= microphyll |
STRUCTURE |
|
A small, lateral, leaf-like enation that, evolutionarily, is not a true leaf, i.e., whose vasculature, if any, consists of only a single median strand not ontogenetically integral with the vasculature of the bearing stem and not associated with leaf gaps in the stele of the stem; in Psilotophyta, Lycopodiophyta, Equisetophyta. |
|
umbonate |
= bossed |
solid shape |
|
Having an umbo. |
|

|
Directed forward or upward, toward the distal end of the context of reference, parallel or at an acute angle to the bearing structure. |
|
biconvex 1 |
= lens-shaped, lenticular |
plane shape |
|

|
muricate |
|
relief |
|
Having short, hard, more or less acute, transversely round protrusions overall. See also muriculate. |
|
caruncle |
= strophiole |
STRUCTURE |
|
An outgrowth from the seed coat (testa) around or near the hilum and micropyle, or from the raphe. |
|
pale 1 |
= palea, palet, receptacular bract |
STRUCTURE |
|
A small papery (chartaceous) to membranous bract borne on the compound receptacle of a capitulum (head) in Asteraceae (Compositae). |
|
cone-shaped |
= conic(al) |
apex |
|
Transversely round, essentially triangular in median longitudinal section, and broadest proximally. See also obconic(al). |
|
pitcher-blade |
= ascidium, pitcher |
STRUCTURE |
|
A pitcher-shaped (ascidiform) leaf blade, sometimes lidded (operculate), usually carnivorous; esp. in Nepenthaceae, Sarraceniaceae. |
|
declined |
= inclined |
orientation |
|
Directed downward or backward. |
|
pyriform |
= pear-shaped |
solid shape |
|
Basically circular in transverse section, broadest toward one end, attenuate toward and much narrower at the other, both ends rounded; slenderly turbinate or obturbinate; like a pear. |
|
ellipsoid(al) |
|
solid shape |
|
Elliptic in any median longitudinal section; elongate, transversely circular, broadest at the middle, and symmetrically convex-attenuate to rounded ends. See also oblong. |
|
S-shaped 1 |
= sigmoid |
course |
|
Curved more or less regularly first in one direction and then in the opposite direction, like the letter S. |

STRUCTURE |
|
