apex |
|
Having a distal boundary that is generally straight or plane and approximately perpendicular to the central axis. |
|
truncate 2 |

Having a generalized proximal boundary that is more or less straight or plane and approximately perpendicular to the central axis. |
|
trunk |
= bole; < main stem, primary stem |
STRUCTURE |
|
The relatively stout, columnar, main stem of a distinct aboveground portion of a tree. |
|
tuber |
|
STRUCTURE |
|
An enlarged, basically subterranean stem segment or thallus outgrowth containing a high proportion of storage tissue and functioning as a perennating and often vegetatively propagative structure. |
|
tubercle |
|
FEATURE |
|
A small, rounded, knot-like swelling or wart-like protrusion. |
|
tubercular |

solid shape |
|
Comprising small knot-like segments. |
|
tuberoid (root-stem) |

STRUCTURE |
|
An axial outgrowth that descends from a bulb and eventually forms a new bulb; esp. in Orchidaceae. |
|
tuberous 1 |
|
architecture |
plant |
Bearing tubers. |
|
tuberous 2 |
|
architecture |
structure |
Resembling a tuber in shape and texture, but not ontogenetically such; esp. roots. |

tubiform |
= trumpet-shaped |
solid shape |
|
Obteretely tubular with a relatively short distal flare (the limb if a perianth, calyx, or corolla). |
|
tubular |
|
solid shape |
|
Cylindric or attenuate-cylindric overall and with a hollow interior open at one or both ends. |
|
tuft |
> coma |
STRUCTURE |
|
A distinct, compact, relatively dense, homogeneous aggregation of plants or constituent structures such as stems, branches, leaves, bracts or trichomes. |
|
tufted 1 |
= cespitose |
habit |
plants |
Growing in distinct, compact, relatively dense, turf-like aggregations. |
|

pubescence |
|
Of or bearing tufts of soft, fine, capillate trichomes that rub off easily. |
|
tumid |
= swollen, turgid |
solid shape |
|
