Non-resupinate
|
Turned 180° in development; e.g., flowers of most orchids in which the lip originates in the uppermost position but twists in such a way that the labellum faces downward at anthesis. Some orchids do not twist, thus the labellum faces up at anthesis. |

|
|
Obdiplostemony (obdiplostemonous)
|
With two series of stamens with twice the number of stamens as petals and those of the outer series inserted opposite the petals and those of the inner series inserted opposite the sepals. Obdiplostemony is sometimes very difficult to determine in flowers at anthesis but become apparent with microtome and SEM studies of bud development (Endress, 2010). |
|
|
Oblanceolada
|
Con forma lanceolada invertida. Se refiere a la forma de una lámina de una hoja u otra estructura similar, cuando es más ancha hacia la porción distal, sus márgenes son divergentes y cuya relación longitud/ancho es 3:1 o mayor |
|
|
Oblanceolate
|
Referring to a leaf, bract, sepal, petal, or other structure in which the greatest width is distal to the midpoint and the length-to-width ratio is 3:1 to less than 6:1. |
|
|
Oblate
|
Spheroidal but flattened at the ends; i.e., slightly broader than long. With the widest point at the middle and the length to width ratio 0.75/1 or less. This term can also refer to both three-dimensional a two-dimensional shapes. |
|
|
Oblate
|
A sphere that is flattened at both poles or a sphere that is shorter in height than it is in width. The term can refer to both three- and two-dimensional shapes. |

|
Oblique

Referring to a leaf base or similar structure in which the two sides are unequal. |
|
|
Obliquely zygomorphic
|
An extension from the abaxial side of the androecium of Cariniana. |
|
|
Oblong
|
Referring to a two dimensional shape in which the greatest width extends throughout a middle zone at least one-third the length of the blade (in this zone the margins are more-or-less parallel) and the length to width ratio is 2:1 to less than 3:1. Other types of oblong shapes are determined by the length to width ratio. |
|
|
Oblonga
|
Se refiere a la forma de una lámina de una hoja u otra estructura similar, cuando posee márgenes paralelos cuya extensión es al menos un tercio de la longitud total de la lámina |
|
|
Oblongoid
|
