|---|---|---|---|---|
| mucilaginous 2 | = mucous; < glutinous | texture | Slimy. | |
| mucous 1 | = mucilaginous; < glutinous | coating | Of a slimy substance, or becoming so upon wetting. | |
| mucous 2 | = mucilaginous; < glutinous | texture | Slimy. | |
| mucronate | apex | Terminating abruptly in a short, hard point that is a continuation of vascular tissue. See also apiculate, mucronulate. | ||
| mucronulate | apex | Finely mucronate. See also apiculate. | ||
| mucro pl. mucrones, mucros | STRUCTURE | A short, hard, apical point that is a continuation of vascular tissue. See also apiculum. | ||
| multi… | = many-…, pluri…, poly… | prefix | Indicating presence of or constitution by a relatively large number of entities of the type denoted by the term's stem; as in multicarpellate, multicellular, multifacial, multiseriate. See also oligo… (few-…). | |
| multiciliate | architecture | Having several to many cilia. | ||
| multicipital | = many-stemmed | architecture | plant | Having many, more or less equal, principal stems arising at substrate level from a caudex or root crown. |
| multiple fruit | = coenocarp, infructescence (not recommended), syncarp; > fig, syconium | nominative | fruit | Compound and derived from the connate or coherent ovaries and accessory tissue(s), if any, of two or more adjacent flowers. |
| muricate | relief | Having short, hard, more or less acute, transversely round protrusions overall. See also muriculate. | ||
| muriculate | relief | Finely muricate. | ||
| muriform | = brickwork-like | arrangement | cells | Disposed like bricks in a wall; in parallel rows, the members in each row overlapping the boundaries between members of the adjacent rows. |
| muscariform | = broom-shaped, penicillate | solid shape | Having a proximal axis that bears a distal cluster of elongate slender branches or appendages, these variously ascending to erect; like a broom. | |
| mushroom-shaped | = fungiform | solid shape | Having a cylindric base and a considerably broader, pulvinate distal portion; like the generalized form of a mushroom. | |
| muticous | apex | Lacking a distinct terminal point (when one might be expected). | ||
| naked 1 | architecture | Lacking a covering that might have been expected. | ||
| naked 2 | architecture | bud | Lacking enclosing protective scales, the outermost embryonic components exposed and not differing significantly from those within. See also perulate. | |
| naked 3 | = achlamydeous | architecture | flower | Lacking a perianth. |
| naked 4 | = epaleate | architecture | receptacle (torus) | Lacking paleae; in Asteraceae (Compositae) |
| napiform | = turnip-shaped | solid shape | Depressed-globose overall and strongly acuminate (concave-tapered) at the base; like the generalized form of a turnip. | |
| navicular | = boat-shaped, cymbiform | solid shape | Like the generalized form of a boat hull, the walls relatively thin to moderately thick, the interior essentially empty and open along one side. | |
| near-bald | = glabrate | pubescence | Nearly glabrous, with only a very sparse covering of trichomes. | |
| neck (archegonial) | STRUCTURE | The distal narrowed portion of an archegonium above its bulbous base. | ||
| neck (floral tube) | STRUCTURE | The solid, usually constricted portion of a floral tube sometimes present between casing and collar when those are both present. |
