Broadly ellipsoid with a length:width ratio closely approaching 1:1; almost globose, slightly longer than broad. |
|
thrice-… |
= tri…, triple-… |
prefix |
|
Indicating presence of three hierarchical orders of the type of entity or pattern denoted by the term's stem; as in thrice-pinnate. See also three-… (tri…). |

STRUCTURE |
|
A longitudinal depression that is relatively shallow and narrow; esp. in fruits of Apiaceae (Umbelliferae). |

plane shape |
|
Basically obovate but with several proximal concavities on each side, these sinuses opposite one another in pairs and decreasing in size toward the base; like the frontal outline of a lyre. |

texture |
|
Hard, dense, fine-grained or compactly fibrous, and tough; resembling the substance of animal horn. |

STRUCTURE |
|
A structurally and functionally specialized root serving as an aboveground aerating organ; found in some woody taxa of wet habitats, notably some mangroves. |
|
…ranked |

arrangement |
|
Disposed along the axis in the number of distinct ranks indicated by the prefix; as in two-ranked. |
