Term
| Vivipary vs. Cryptovivpary |
|
Definition
Vivipary-Hypocotyl (embryonic stem) breaks through seed coat and fruit wall while still attached to parent plant (Rhizophora mangle).
Cryptovivipary-Hypocotyl breaks through seed coat while attached to parent plant (Avicennia germinas and Laguncularia racemosa), but through the fruit wall after it drops off. |

| FW marshes with little water movement; similar to Lacustrine marshes (but no express connection with a lake). |
|
|
Term
|
Definition
| FW marsh occuring along rivers and streams. This type of marsh has high water flow, but are not widespread (swamps usually dominate this area). |

|
Definition
| Type of depressional marsh that retains some level of water all year. |
|
|
Term
|
Definition
| Type of depressional marsh that does not necessarily retain water year-round. Can be vernal (small) pools or playas (>1 acre). These marshes have a high degree of endemism. |
