| Term | Definition | |

| Anther dehiscence poricidal | Anthers that open (dehisce) and release pollen via a terminal pore. |  |
| Anther theca (pl. = thecae) | The chambers of an anther in which the pollen is produced. Same as pollen sac. |  |
| Antherode | The anther of a staminode; an anther that bears pollen that does not germinate. |  |
| Anthers basifixed | Anthers attached to their filaments at the very base. |  |
| Anthers black | Anthers that look black at anthesis either because the anther is black or because the pollen is black. |  |
| Anthers orange | Anthers that look orange at anthesis either because the anther is orange or because the pollen is orange. |  |
| Anthers versatile | Anthers that are attached above the base and can be moved more freely on the apices of their filaments than can anthers that are attached at their bases (= anthers basifixed). | |
| Anthers white | Anthers that look white at anthesis either because the anther is white or because the pollen is white. White anthers are common in neotropical Lecythidaceae. |  |
| Anthers yellow | Anthers that look yellow at anthesis either because the anther is yellow or because the pollen is yellow. |  |
| Anthesis | The expanding and opening of a flower; another way of saying "in flower." |  |
| Appendage-free ligule | The part of a ligule between the staminal ring and the androecial hood that is free of stamens, staminodes, and vestigial stamens (collectively called appendages), or at least the appendages are very sparse compared to their density in the staminal ring or on the hood. |  |
| Appendages | Same as androecial appendages. | |
| Arched tertiary veins | Referring to tertiary veins that orginate from the midrib and arch downward to the infra adjacent secondary vein. |  |
| Areole (areolate) | Referring to the smallest area of leaf tissue surrounded by veins, the sides of which can be comprised of any order of vein (Ellis et al., 2009). |  |
| Aril | A fleshy outgrowth from the base of the funicle. |  |
| Aril basal | An aril located at the base of the seed. |  |
| Aril basal-lateral | An aril starting at the base and extending part way up the side of the seed. |  |
| Aril half I-beam | An aril that runs the length of the side of the seed and then abruptly turns to cover one or both ends of the seed. |  |
| Aril lateral | An aril that runs along the side of the seed such as in many, but not all, species of |
 |
| Aril spreading | The aril spreads around the entire seed and, thus, looks like a sarcrotesta. In contrast to a sarcotesta, a spreading aril arises from the I-beam aril and not the seed surface. |  |
| Articulation | A joint between two separable parts, e.g., between a leaf and a stem or between a lower and upper part of a pedicel, |  |
| Asymmetric | Referring to a structure that can be divided into numerous mirror-image halves. This and its associated terms are usually, but not exclusively, applied to flowers. Opposite of symmetric. |  |
| Awn (awned) | The terminal extension of the midrib of an organ such as a bract (bearing awns). |  |
| Axillary | Referring to a structure that arises from the leaf axils. | |
| Axillary inflorescence | A inflorescence that arises from a leaf axil |  |
| Bark | The tissue of the trunk and branches external to the vascular cambium. |  |
| Bark fissured | Bark with distinct longitudinal grooves. |  |
| Bark not fissured | A bark that does not have conspicuous vertically oriented fissures. |  |
| Bark rough | Bark without fissures and scallops yet with very shallow irregular cracs and often shedding small pieces of bark. |  |
| Bark scalloped | A bark that peels in irregular plates that leave conspicuous depressions. |  |
| Bark smooth | A bark without fissures, scallops, or roughness. | |
| Blade | The expanded part of the leaf supported by the petiole |  |
| Blaze | See slash. | |
| Bole | In trees, the unbranched portion of the stem. Same as trunk. |  |
| Brachyparacytic stomata | Same as paracytic stomata | |
| Bract | A reduced and frequently otherwise differentiated leaf that is often associated with inflorescences and subtends the pedicels of flowers. |  |
| Bracteole (adj. = bracteolate) | A small bract usually inserted on the pedicel. In the Lecythidaceae bbracteoles usually are in pairs inserted on pedicels. | |
| Bracteoles above articulation | Bracteoles inserted above the bracteoles in the pedicel/hypanthium continuum of Lecythidaceae. |  |
| Bracteoles below articulation | Bracteoles inserted below the articulation in the pedicel/hypanthium continuum of Lecythidaceae. | |
| Branch | All divisions of a plant. |  |
