|
architecture |
compound or compound-complex structure |
Having the number of equivalent component parts indicated by the prefix (e.g., petals in a corolla), or having different component sets of equivalent parts of that number in each set (e.g., calyx and corolla in a perianth); as in monomerous, oligomerous, polymerous, tetramerous, trimerous. |

motile |
|
habit |
|
Able to translocate by intrinsic means, as by flagellar propulsion. |
deliquescent 1 |
|
