sword-shaped 1 |

Upon the leaves, or partially adnate thereto and apparently arising therefrom. |
|

position |
|
Within, upon, or otherwise directly associated with the bark. |
|
ceraceous 2 |
cereous, waxen, waxy |
texture |
|
Having the consistency of wax. |
|
stellate 2 |
= star-shaped |
plane shape |
|
Having four or more intersecting radiate lobes or portions, each distally slender; like the stylized outline of a star. |
|
pith |
|
STRUCTURE |
|
The central ground tissue of a stem or, when present, of a root, consisting of thin-walled parenchyma cells; distinct and more or less soft and spongy relative to the other tissues of the axis; sometimes partly or wholly degenerating after secondary growth has begun. |
|
pseudoaxillary |
|
insertion |
|
Only apparently axillary; originally extraaxillary but displaced to the axil by differential growth during development. |
|
leftward |
= sinistrorse |
orientation |
|
Directed to the left, relative to the direction of growth along an explicit or implicit axis of reference. See also rightward (dextrorse). |
|
torus 2 pl. tori |
= receptacle |
STRUCTURE |
|
The short, expanded, compound axial structure surmounting a peduncle and basal to two or more flowers, or to the florets of a capitulum (head) in Asteraceae (Compositae), where it may bear paleae (receptacular bracts), scales, bristles, trichomes, or subulate enations, and may be smooth or variously pitted (alveolate, foveolate). |
|
firm |
|
texture |
|
Yielding under only moderately strong pressure; only slightly deformable without internal structural disruption. |
|
arcuate 1 |
|
course |
|
Curving more or less regularly in one direction. |
|
bracteate |
= bracted |
architecture |
|
Bearing or subtended by one or more bracts. |
|
pallid |
|
coloration |
|
Relatively pale; not strongly colored. |
|
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). |
|
compound |
= composite |
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). |
|
inflexed |
|
orientation |
|
Bent adaxially at some point along its length. |
|
suffused |
|
coloration |
|
Having two or more hues, shades, and/or intensities intermingled, the contrasting components distinguishable only submacroscopically. |
|
embryotega pl. embryotegae, embryotegas |
|
STRUCTURE |
|
A small, hardened, lid-like portion of the testa (seed coat) at the micropyle of some seeds, detaching at germination. |
|
reniform 1 |
= kidney-shaped |
plane shape |
|
Broadly elongate and arcuate, each end bluntly rounded; like the generalized outline of the broad face of a human kidney. |
|
massula pl. massulae |
|
STRUCTURE |
|
A body of coherent pollen grains, dispersed as a unit; esp. in Asclepiadaceae, Orchidaceae. |
|
unilateral 2 |
= one-sided |
orientation |
|
Disposed or directed toward one side only. |
|
nectar |
|
SUBSTANCE |
|
An aqueous exudate of high sugar content. |
|
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." |
|
bearded |
= barbate |
pubescence |
|
Having one or more limited sectors bearing relatively long, erect, flexible, capillary trichomes. |
