spatulate var. spathulate |
= spatula-shaped |
plane shape |
|
Elongate, broadest near a rounded apex, gradually attenuate to a narrower base; like the outline of the broad face of a spatula blade. |

STRUCTURE |
|
A motile male gamete, produced within an antheridium. |

|
fusiform |
= spindle-shaped |
solid shape |
|
Elongate, transversely round, broadest at the middle and regularly attenuate to either end. |
|
thorn |
= spine |
STRUCTURE |
|
Any sharp, stiff, simple or branched, woody appendage having vascular tissues confluent with those of the bearing structure. "Spine" is often preferred when the appendage is homologous with a leaf or stipule, and "thorn" when it is homologous with a branch. See also prickle. |
|
echinate |
= spinose, spiny |
architecture |
|
Bearing spines. |
|
aculeate |
= spinose, spiny |
margin |
|
Having slender, stiff, sharp projections oriented in the general plane of the structure. |
|
helical 2 |
= spiral |
course |
|
Curving with regularly increasing radius from one end to the other in one general plane. |
|
helical 3 |
= spiral |
course |
|
Curving with constant or regularly increasing radius from one end to the other through three dimensions. |
|
strombuliform |
= spire-shaped |
solid shape |
|
Attenuate-spiral in three dimensions, the coils contiguous or not. |
|
glittering |
= splendent |
reflectance |
|
Interruptedly glossy (laevigate, lustrous, polished, shining, shiny, and thus sparkling when viewed from changing angles. |
|
spore case |
= sporangium |
STRUCTURE |
|
A spore-producing organ; basically capsular, often supported by a slender stalk (sporangiophore), often lidded (operculate). In Bryophyta and Polypodiophyta, a distinct portion of the sporangial wall effects regular dehiscence at maturity. Spore cases or their equivalents are also present, but of little or no descriptive significance, in seed plants. |
|
sporocarp |
= spore body |
STRUCTURE |
|
A multicellular structure that bears and more or less encloses several to (usually) many sporangia, the latter often aggregated into sori within it See also megasporocarp (macrosporocarp, not recommended), microsporocarp. |

|
short-shoot |
= spur |
STRUCTURE |
|
A first- or higher-order woody stem branch having relatively unelongated internodes, thus proximate nodes, and limited duration of growth, usually branching little if at all; often a main locus of flower production; usually more or less perpendicular to the axis that bears it and resembling a spur projecting from it; sometimes becoming more or less spinose after elongation ceases; esp. in Rosaceae. |
|
calcarate |
= spurred |
base |
|
Having a relatively slender protrusion resembling a spur. |
|
lepis pl. lepides |
= squama; < scale, trichome |
STRUCTURE |
|
A relatively thick, planate trichome. See also squamella. |
