shoot 2 |
|

|
A vascularized axis that is differentiated into nodes and internodes and that branches exogenously from the former, together with any non-axial structures borne from it. |
|
vallecular |
|
insertion |
|
In or otherwise directly associated with the valleculae; esp. in fruits of Apiaceae (Umbelliferae). |
|
elaiosome |
|
STRUCTURE |
|
A fleshy outgrowth from the seed coat (testa) that contains a high proportion of oil, usually attracting ants for dispersal. |
|
microphyllous |
|

|
architecture |
flower, perianth, corolla |
Having the petals essentially alike in size and shape. |
|
peripheral |
|
position |
|
Upon or otherwise directly associated with the outer surfaces or regions of a three-dimensional structure. Although use of this term in two-dimensional contexts is technically correct, traditionally the term marginal is preferred in such cases. |
|
ephemeral |
|
duration |
plant |
Annual with a very short life span; germinating, growing, reproducing, and dying within a brief period of favorable conditions, the entire cycle being completed within a few weeks. |

|
architecture |
|
Divisible into essentially equal halves along one or more lines or planes. |
|
cotyloid |
|
architecture |
flower |
Having general adnation among the different sets of floral structures, thus having the ovary inferior and/or having a floral tube. |
|
lacuna pl. lacunae |
|
FEATURE |
|
A hole or cavity; an empty space surrounded by tissue in two or three dimensions. |
|

|
architecture |
flower |

tepal |
|
STRUCTURE |
|
Any member of an undifferentiated perianth; may be green and foliaceous or colored and petaloid, distinct or else connate with one or more others, and/or free or else adnate with one or more other floral structures. |
|
cryptic |
|
coloration |
|
Similar to its natural background, from which it is not readily distinguished. |
|
centrifugal |
|
development |
|
Proceeding away from the center, thus more advanced centrally than peripherally within a given frame of reference. |
