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. |
|
monadal |
|
arrangement |
pollen |
Shed singly, or essentially so, only loosely and irregularly, if at all, coherent, each original tetrad having separated fully. |
|
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. |
|
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. |

|
midvein |
= midnerve, midrib; < costa, nerve, rib, vein |
STRUCTURE |

|
microsporocarp |
|
STRUCTURE |
|
A sporocarp that bears only microsporangia. |
|
microspore |
|
STRUCTURE |
|
A male spore; a spore of the smaller of the two types produced by the sporophytes of a heterosporous taxon; produced in a microsporangium; giving rise upon germination to a microgametophyte. |
|
microsporangium pl. microsporangia |
|
STRUCTURE |
|
A sporangium that produces microspores. |
|
micropyle |
|
FEATURE |
|
The small pore in the integuments of an ovule at its apex, through which the pollen tube grows; or the corresponding aperture or scar in the coat of the seed that develops subsequently. |
|

|
architecture |
plant |
Bearing microphylls. |
|
microphyll |
|
STRUCTURE |
|
A small, lateral, leaf-like enation that, evolutionarily, is not a true leaf, i.e., whose vasculature, if any, consists of only a single median strand not ontogenetically integral with the vasculature of the bearing stem and not associated with leaf gaps in the stele of the stem; in Bryophyta, Psilotophyta, Lycopodiophyta, Equisetophyta. |
|
