FEATURE |

A diminutive crena (scallop). See also dens (tooth), sawtooth, sawtoothlet, toothlet. |
|
primocane |

STRUCTURE |
|
A biennial or perennial stem before it has begun flowering, when the latter does not occur until at least its second season of growth; esp. in Rubus (Rosaceae). |
|
dissected |
? cleft, divided, lobate, lobed, parted, partite, segmented |
plane shape |
|
Having two or more component sectors or peripheral protrusions that are delimited by concavities in the surface or margin and that are not proximally distinct from the remainder of the whole. The meanings of this term and its approximate synonyms sometimes have been supposed to differ according to the depth of the delimiting concavities relative to the midline or midpoint of the overall structure, and/or to the shape or proportions of the protusions or sectors; however, there has been little consistency in the applications of the various terms according to such distinctions, which are ones only of degree and are necessarily arbitrary in any case. In general usage, these terms differ only indistinctly and connotatively: cleft, lobed (or lobate), parted (or partite) and segmented tend to connote fewer protrusions or sectors; lobate usually connotes as well a generally rounded shape; dissected tends to connote more numerous sectors that are elongate and angular. See also cut (incised, lacerate, torn), laciniate (slashed). |
|
reticulodromous |

Upon or otherwise directly associated with the internodes. |
|
liguliform |

solid shape |
|

|
acute |

Sharply angular; regularly and more or less straightly attenuate to an angular tip, the sides intersecting at an angle of less than 90°. |
|
macrosporophyll (not recommended) |

STRUCTURE |
|
A sporophyll that bears only megasporangia and, in Pinophyta, naked ovules that develop subsequently. |
|
bractleted |
= bracteolate |
architecture |
|
Bearing or subtended by one or more bractlets (bracteoles, prophylls). |
|

FEATURE |
|
A longitudinal, transversely rounded depression; esp. along the adaxial surface of a petiole or petiolule. |
|
parchment-like |
= pergamentaceous |
texture |
|
Very thin, pliable, and fairly tough; like parchment. See also chartaceous (papery, papyraceous), membranaceous (membranous). |
|
corolla tube 2 |
|
STRUCTURE |
|
The portion of the corolla of a bisexual or staminate disc floret proximal to the level of filament insertion; in Asteraceae (Compositae). |
|
pollinium pl. pollinia |
|
STRUCTURE |
|
A mass of coherent pollen grains disseminated as a unit by adhering to a pollinating insect, representing the entire content of a single theca or of fused thecae; often distally attenuate to a sterile caudicle (translator arm), which may attach to a viscidium, either directly or through an intervening stipe; esp. in Asclepiadaceae, Orchidaceae. |
|
ray 2 |
= lamina |
STRUCTURE |
|
The distal, relatively flat portion of the corolla of a ray floret, terminating in 0--4 teeth or lobes; in Asteraceae (Compositae). |

= hypanthium (strict sense) |
STRUCTURE |
