antisepalous |
|
insertion |
equivalent floral structures |
Each inserted directly above or below a sepal. In place of this term, the phrase "opposite the sepals" is often used, but that contradicts the sense of opposite as otherwise employed (arrangement of lateral structures along an axis) and should be avoided. |

fusion |
equivalent and/or dissimilar structures |
Partially and irregularly coherent and/or adherent. |
|

A compound (branched) raceme, the elongate main axis either determinate or indeterminate, its lateral branches racemose. |

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. |
|
chaff 1 |

STRUCTURE |
|
Collectively, the paleae (pales, palets) sometimes borne on the receptacle of a capitulum (head) in Asteraceae (Compositae). |
|
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. |
|
mammose |
|
solid shape |
|
Having mammae. |
|
complex |
|
architecture |
|
Comprising two or more basic structural entities, at least two of which are dissimilar. |
|
inframedial |
|
position |
|
Slightly below the middle of the structure in point. |
|
eccentric |
|
position |
|
Having a center or axis of symmetry not coincident with that of the context of reference. |
|
asymmetric(al) 2 |
|
architecture |
flower |
Having the perianth members in whorls that are irregular and/or unequal in number of members. |
|
radicle |
|
STRUCTURE |
|
The primary root, or its primordium, in an embryo; the portion of an embryo axis that develops into the root. |
|
contortuplicate 2 |
|
vernation |
|
Folded and twisted. |
|
involute 1 |
|
margin |
|
Rolled adaxially. |
|
pericolpate |

architecture |
pollen grain |
Having more than three surficial grooves (colpi) oriented such that some or all of them cross meridians. |
|
contractile |
|
architecture |
structure |
Diminishing in length, or acquiring the potential energy for a sudden decrease, due to the generation of internal tension during tissue development. |
|
involute 2 |
|
vernation |
|
Each rolled adaxially from the lateral margins. |
|
pericolporate |
|
architecture |
pollen grain |

|
FEATURE |
|
A circumferential ring about a megaspore in the plane of its equator, raised above the remainder of the wall surface; in some heterosporous taxa of Polypodiophyta. |
