arrangement |
pollen |
Shed in groups of four, each an intact tetrad with original configuration unchanged; geometric arrangement of the grains may be tetrahedral, tetragonal, or linear, depending upon mode of pollen mother cell division. |
|
cyathiform |

solid shape |
perianth, calyx, corolla, pappus |
Having a cupulate tube and an indistinct, erect limb. See also cotyliform, urceolate (urn-shaped). |
|
chasmogamous |
|
reproduction |
flower |
Having the perianth open at anthesis, allowing deposit of pollen from other flowers (physiological receptivity aside). |
|

|
reproduction |
taxon |
Basically monoecious but with some or all plants bearing some bisexual flowers. |
|
autotrophic |
|
nutrition |
plant |
Independent of other organisms for its nourishment, itself synthesizing all essential substances not directly available from the non-living environment. |
|
hemispheric(al) |
|
solid shape |
|
Half-spheric(al); broadest at the base and uniformly rounded to the apex, circular in any transverse section, and half-circular in any median longitudinal section. |
|

|
prominence |
|
CHARACTER |
|
Elevation or depression of a discrete feature relative to the surrounding surface. |

plane shape |
|
Having a relatively broad circumferential rim or ridge that protrudes laterally. |

FEATURE |

Compound with two orders of leaflets, each order bifoliolate. |
|
semicircular |
|
arrangement |
