| Term | Synonyms | Category | Limitation | Definition |
|---|---|---|---|---|
| midnerve | = midrib, midvein; < costa, nerve, rib, vein | STRUCTURE | A primary vein that runs longitudinally through the center of a leaf or other basically laminar structure. See also lateral vein, secondary vein, tertiary vein, veinlet. | |
| midrib | = midnerve, midvein; < costa, nerve, rib, vein | STRUCTURE | A primary vein that runs longitudinally through the center of a leaf or other basically laminar structure. See also lateral vein, secondary vein, tertiary vein, veinlet. | |
| midvein | = midnerve, midrib; < costa, nerve, rib, vein | STRUCTURE | A primary vein that runs longitudinally through the center of a leaf or other basically laminar structure. See also lateral vein, secondary vein, tertiary vein, veinlet. | |
| mitre-shaped | = mitriform | solid shape | Broadest and transversely round to oval proximally, tapering bilaterally above the middle to a central peak; like a peaked hat or cap. | |
| mitriform | = mitre-shaped | solid shape | Broadest and transversely round to oval proximally, tapering bilaterally above the middle to a central peak; like a peaked hat or cap. | |
| mixed-craspedodromous | venation | Having a midvein that branches to either side along the length of the lamina, the secondary veins running thence toward the margin, some becoming indistinct before reaching it, others terminating there. | ||
| monadal | arrangement | pollen | Shed singly, or essentially so, only loosely and irregularly, if at all, coherent, each original tetrad having separated fully. | |
| moniliform | = beaded | solid shape | Elongate, relatively slender, transversely round, and more or less regularly constricted over its length, the whole straight or variously curved; like a necklace of beads. | |
| mono… | = one-…, single-…, uni… | prefix | Indicating presence of or constitution by one entity of the type denoted by the term's stem; as in monandrous, monocolpate, monocyclic. See also entries for particular terms with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. | |
| monocarpic | = hapaxanthic | reproduction | plant | Normally reproducing sexually only once, then promptly senescent. |
| monochasiate | architecture | inflorescence | Comprising one or more simple or compound monochasia. See also cincinnate, cymose, cymulose, dichasiate, helicoid-cymose, scorpioid-cymose. | |
| monochasiform | = monochasium-like | architecture | capitulescence, inflorescence | Resembling a monochasium, but not strictly such. |
| monochasium-like | = monochasiform | architecture | capitulescence, inflorescence | Resembling a monochasium, but not strictly such. |
| monochasium pl. monochasia | nominative | inflorescence | Determinate and falsely dichotomous with each axial segment bearing a single, sessile terminal flower; presumably derived from a dichasium by loss of the lateral flowers. See also cincinnus, cyme, cymule, dichasium, helicoid cyme, scorpioid cyme. | |
| monochlamydeous | architecture | flower | Having a monocyclic perianth. | |
| monoclinous | = synoecious | reproduction | taxon | Having all flowers functionally bisexual; this condition is implied by default if no other is specified. See also diclinous. |
| monoecious | < diclinous | reproduction | taxon | Having all flowers or spikelets functionally unisexual, and all plants having both staminate and pistillate types. See also dioecious. |
| monolete | architecture | spore | Having a single linear tetrad scar (surficial ridge or angle resulting from ontogenetic coherence with others produced from the same spore mother cell). | |
| monopodial | architecture | axes | Branching laterally, each axis of each order of branches produced by a single, persistently dominant, apical meristem. See also sympodial. | |
| …morphic | architecture | Existing within the taxon in the number of distinct structural states indicated by the prefix, the states segregated in different sets of plants or not; as in monomorphic, polymorphic, trimorphic. | ||
| motile | habit | Able to translocate by intrinsic means, as by flagellar propulsion. | ||
| mottled | coloration | Having one or more indistinctly delineated, irregularly shaped, areas of varying size and contrasting hue and/or intensity. | ||
| mound-shaped | = cushion-shaped, pulvinate, pulviniform | solid shape | Essentially round in transverse section, much broader than long or high, with a convex distal face that intersects either a more or less plane proximal face or, when the structure is sessile, its bearing surface. | |
| mucilage | substance | A slimy exudate. | ||
| mucilaginous 1 | = mucous; < glutinous | coating | Of a slimy substance, or becoming so upon wetting. |
