duration |
plant, stem |
Normally living one year or less; growing, reproducing, and dying within one cycle of seasons. |
|

insertion |
|
Upon or otherwise directly associated with the costa(e) of a laminar structure. |
|
pilosulous |
|
pubescence |
|
Finely pilose. |
|

|
texture |
|
Liquid and weakly cohesive, flowing freely; like water. This term often implies also transparency. |
|

SUBSTANCE |
|
An aqueous exudate of high sugar content. |
|
rhytidomal |
|
insertion |
|
Within, upon, or otherwise directly associated with the bark. |
|
cauline |
|
position |
|
Upon, arising from, or otherwise directly associated with the stem. |
|
lateral |
|
position |
|
To, toward, at, or upon a side, not apical or basal. |
|
planoconvex |
|
solid shape |
|
Relatively thin with opposite broad faces, one plane and one convex. |
|
extravaginal |
|
position |
|
Distal to or outside the leaf sheath. |
|
nutlet |
|
nominative |
fruit |
A small, relatively hard-coated mericarp; esp. in Lamiaceae (Labiatae), Verbenaceae. |
|
cylindric(al) |
|
solid shape |
|
Solid and transversely round with a more or less uniform diameter, the ends blunt. |
|
levering |
|
habit |
trichome |
Forming part of a pappus and reflexing at maturity, thus helping to loosen the individual fruit (cypsela) from the capitulum (head); in Asteraceae (Compositae). |
|
stamen |
|
STRUCTURE |
|
A seed-plant organ that produces and releases pollen; usually comprising a stalk (filament) that bears a locular structure (anther) containing sporogenous tissue; however, the filament may be lacking and the anther sessile, or the stamen may be undifferentiated, the whole then consisting of microsporangia embedded in or borne upon the surface of a more or less planate body of sterile tissue; one of the constituent organs of a bisexual or a staminate flower; may be distinct or else connate with one or more others and/or may be free or else adnate with one or more other floral structures. |
|
obvolute 1 |
|
arrangement |
cotyledons |
Having each cotyledon folded inward longitudinally, the two facing one another with their edges overlapping alternately (each enveloping one side or the other). |
|
basipetal |
|
development |
|
Proceeding toward the base, thus more advanced apically or distally than basally or proximally within a given frame of reference. |
|
prothallus pl. prothalli |
|
STRUCTURE |
|
A very diminutive thallus that is reproductively mature and undergoes no further growth; in Polypodiophyta, Pinophyta. |
|
coalescent |
|
fusion |
equivalent and/or dissimilar structures |
Partially and irregularly coherent and/or adherent. |
|
panicle |
|
nominative |
inflorescence |
A compound (branched) raceme, the elongate main axis either determinate or indeterminate, its lateral branches racemose. |
|
sepal |
|
STRUCTURE |
|
One of the one or more constituent members of a calyx; usually green and leaf-like, but sometimes with color and/or texture otherwise, sometimes petaloid; may be distinct or else connate with one or more others and/or may be free or else adnate to one or more other floral structures. |
|
umbellate |
|
architecture |
inflorescence |
Comprising one or more umbels. |
|
adventitious |
|
derivation |
|
Arising more or less unpredictably from an organ, tissue, or site that is an unusual, abnormal, or atypical origin for structures of its type. |
|
follicle |
|
nominative |
fruit |
Dry, longitudinally dehiscent, one-locular, one- to many-seeded and derived from a single, superior, simple ovary; dehiscing along a single adaxial suture. |
