| Androecial hood | In zygomorphic-flowered Lecythidaceae with ligules, the distal part of the ligule that has become modified either by the outgrowth of appendices (= staminodes, vestigial stamens, or nectar-producing vestigial stamens), by an abrupt change in direction of the ligule, or by both. Androecial hoods are usuallly separated from the staminal ring by an appendage-free part of the ligule (the only known exception is |
 |
| Androecial hood appendages swept inward | A androecial hood type in which appendages arise from an expanded apical or subapical part of the ligule from where they curve into the flower but do not form a coil (e.g., as in species of |
 |
| Androecial hood double-coiled | The androecial hood is coiled twice inward. |  |
| Androecial hood flat | The androecial hood is not curved or coiled inward at all |  |
| Androecial hood flat, thick | The androecial hood, as seen in medial longitudinal section, is thickened dorsiventrally. |  |
| Androecial hood flat, thin | The androecial hood is not curved or coiled inward and it is not thickened as viewed in a medial longitudinal section. |  |
| Androecial hood horizontally oriented (= hood horizontally oriented) | An androecial hood with the first coil oriented at more-or-less 90 degrees to the main axis of the flower. |  |
| Androecial hood obliquely oriented (= hood obliquely orientated) | An androecial hood that is oriented at an angle less than 90 degrees to the main axis of the flower. |  |
| Androecial hood once-coiled | The androecial hood turns inward once |  |
| Androecial hood split | A separation of the androecial hood into a posterior hood extension and an anterior hood extension. |  |
| Androecial hood triple-coiled | The androecial hood makes three turns inward |  |
| Androecial hood: Bertholletia-type | The Bertholletia-type of androecial hood has appendages that are swept back into the interior of the hood which are called vestigial stamens; these appendages do not have anthers. | |
| Androecial hood: Corythophora alta-type | A thickened hood, bearing staminodes. |  |
| Androecial hood: Couratari-type | The androecial hood has an extra external flap found only in species of |
 |
| Androecial hood: Couroupita guianensis-type | In this type of hood, there is an appendage-free area between the staminal ring and the androecial hood proper. The appendages bear normal looking anthers but they contain fodder pollen (=staminodes) and the hood is slightly thickened. |  |
| Androecial hood: Couroupita subsessilis-type | This type of androecial hood has three features: 1) an invagination, 2) a notch on the distal end as viewed from above, and 3) staminodes. |  |
| Androecial hood: Eschweilera-type | In this type of hood, the interior of the hood forms an inward coil and the vestigial stamens at the end of the coil are nectar-producing. |  |
| Androecial hood: Lecythis corrugata-type | In this type of androecial hood, the hood is flat and thickened, there are no appendages with anthers on the hood, and the vestigial stamens are poorly developed. | |
| Androecial hood: Lecythis idatimon-type | The androecial hood is flat and there are only vestigial stamens representing the appendages of the hood. |  |
| Androecial hood: Lecythis ollaria-type | This type of androecial hood turns inward but does not form a complete coil, the vestigial stamens are all the same size, and lack anthers; thus, they are called vestigial stamens. |  |
| Androecial hood: Lecythis persistens subsp. persistens-type | The androecial hood of this type is flat and the appendages of the hood are with anthers that bear fodder pollen and, thus, are called staminodes |  |
| Androecial hood: Lecythis pisonis-type | The androecial hood is separated from the staminal ring, the hood is flat, and there are staminodes proximally and vestigial stamens distally. | |
