|
STRUCTURE |
|
A hollow protrusion from a calyx or corolla, often nectariferous. |
bark |

spinose 1 |
|
apex |
|
Terminating in a rigid, tapering, sharp continuation of the central primary vein. See also spinulose. |
stipule |
|
STRUCTURE |
|
Any distinct, relatively diminutive, more or less foliaceous structure inserted on a stem alongside a petiole, or on a petiole near its base, and ontogenetically closely associated with the leaf; usually occurring as one of a pair disposed one to either side of the petiole. |
corolla tube 1 |
|
STRUCTURE |
|
A relatively narrow, fully connate portion of a sympetalous (gamopetalous) corolla proximal to a broader portion (limb) that comprises the distinct or connate distal portions of the petals; except in bisexual or staminate disc florets of Asteraceae (Compositae). |
mixed-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, some becoming indistinct before reaching it, others terminating there. |
cypsela pl. cypselae |
|
nominative |
fruit |
Like an achene but derived from an inferior, bicarpellate ovary and with accessory perianth tissue adnate to the pericarp; esp. in Asteraceae (Compositae). |
stylopodium pl. stylopodia |
|
STRUCTURE |
|
A discoid enlargement at the base of the styles; esp. in Apiaceae (Umbelliferae). |
diplostemonous |
|
architecture |
flower, androecium |
Having the stamens dicyclic, the proximal whorl with members directly above the sepals, the distal whorl with members directly above the petals. See also obdiplostemonous. |
bulliform |
|
solid shape |
|
Resembling a blister; broad, relatively thin at the periphery, the lower surface approximately flat, the upper shallowly to strongly convex. |
ovary |
|
STRUCTURE |
|
The proximal portion of a pistil (either simple or compound) within which the ovules are borne; usually of somewhat greater diameter and/or volume than the remainder of the pistil. |
emersed |
|
location |
structure of aquatic plant |
Above the water surface. |
oil-secreting |
|
exudation |
|
Producing and exuding an oily substance, often aromatic; when oil-secreting glands are indicated in the nominative, often they are called simply oil glands. |
suprabracteal |
|
position |
|
Upon the axes, each directly above (distal to) and very near a point of bract insertion. |
tillering |
|
architecture |
plant, stem |
Producing tillers; esp. in Poaceae (Gramineae) and other monocotyledons (Liliidae). |
exfoliating |
|
relief |
bark |
Shallowly and distantly fissured, falling away in thin, relatively large patches or sheets. |
