cuculliform |
= cucullate, hood-shaped |
solid shape |
|

solid shape |

farinaceous 2 |

Loose, dry, and disintegrating in finely granular pieces like meal or flour. |
|
fusion |
|
CHARACTER |
|
Physical connection of equivalent or dissimilar structural entities (as recognized on evolutionary, morphological, anatomical, ontogenetic, and/or topological grounds). Terms that denote the interconnection of equivalent structures are predicated on a single collective subject and suffice in themselves to describe the condition; e.g., "sepals connate." However, those that denote the connection of dissimilar structures require explicit notation of each type of structure involved, in either a compound-subject construction or else a single-subject/object-of-preposition construction; e.g., "stamens and corolla adnate" or "stamens adnate to corolla." Qualifying detail is sometimes appropriate; e.g., "filaments connate basally," "filaments adnate to the petals over their lower halves." |
|
squama pl. squamae |
= lepis; < scale, trichome |
STRUCTURE |
|
A relatively thick, planate trichome. See also squamella (squamule). |

Having the number of sulci indicated by the prefix; esp. pollen grains; as in monosulcate, polysulcate, 3-sulcate. |
|
transverse 2 |
|
orientation |
|
Perpendicular to the long axis of the context of reference. |
|
verticillate |
= cyclic, seriate, whorled |
arrangement |
|
Disposed along the axis in groups of three or more, the members of each group (cycle, series, verticil, whorl) inserted regularly around the axis at the same level. |
|
medial |
= central, median |
position |
|
At, upon, or closely ranged about the structural or symmetrical midpoint or axis. |
|
bullate |
= blistered, puckered, pustulate |
relief |
|
Having relatively coarse, irregularly disposed, rounded protrusions or convexities resembling blisters. See also papillate (papillose). |
|
prickly |
|
architecture |
|
Bearing prickles. |
|
discoid 1 |
= disciform |
solid shape |
|
Relatively thin with two round, plane or convex, opposite broad faces and a rounded circumferential edge; like a disc. See also lenticular (biconvex, lens-shaped), meniscoid, placentiform (placenta-shaped), trochlear (pulley-wheel-shaped). |
|
resinous 2 |
|
texture |
|
Having the consistency of resin. |
|
four-… |
= quadr(i)…, tetra… |
prefix |
|
Indicating presence of or constitution by four entities of the type denoted by the term's stem; as in four-angled, four-petaled, four-ranked. |
|
spine |
= thorn |
STRUCTURE |
|
Any sharp, stiff, simple or branched, woody appendage having vascular tissues confluent with those of the bearing structure. "Spine" is often preferred when the appendage is homologous with a leaf or stipule, and "thorn" when it is homologous with a branch. See also prickle. |
|
head-shaped |
= capitate, capitiform |
solid shape |
|
Basically globose and resembling a head in the context of occurrence. |
|
subglobose |
= suborbicular, subrotund, subspheric(al), subspheroid(al) |
solid shape |
|
Broadly ellipsoid with a length:width ratio closely approaching 1:1; almost globose, slightly longer than broad. |
|
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…). |
|
ligule 1 |
|
STRUCTURE |
|
A strap-shaped enation from or distal portion of a structure. |
|
vallecula pl. valleculae |
= colpus, fossula, furrow, groove, sulcus |
STRUCTURE |
|
A longitudinal depression that is relatively shallow and narrow; esp. in fruits of Apiaceae (Umbelliferae). |
|
ligule 2 |
|
STRUCTURE |
|
An adaxial, distal enation from a leaf sheath, especially in most grasses (Poaceae) and sedges (Cyperaceae); usually unitary and membranous, sometimes instead consisting of a row of ciliate processes. See also hastula. |
|
vallecular |
|
insertion |
|
In or otherwise directly associated with the valleculae; esp. in fruits of Apiaceae (Umbelliferae). |
|
areolate |
|
relief |
|
Having numerous, small, irregularly disposed, transversely angular, shallow depressions or low protrusions overall. |
|

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. |
|
bracteolate |
= bractleted |
architecture |
|
Bearing or subtended by one or more bracteoles (bractlets, prophylls). |
