prefix |
|
Indicating presence of or constitution by one entity of the type denoted by the term's stem; as in unicellular, unifloral, unifoliate. 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. |
|

= capitiform, head-shaped |
solid shape |
|
Basically globose and resembling a head in the context of occurrence. |
|
furcate |
