| Term | Definition | |
|---|---|---|
| Branched inflorescence | An inflorescence with at least two orders of rachises, i.e., the central rachis has branches emanating from it. |  |
| Bud | A young shoot from which leaves or flowers may develop, the former is a leaf bud and the latter is a flower bud. |  |
| Calycine rim | Referring to a calyx in which the calyx-lobes are fused at their bases to form a rim that extends beyond the summit of the ovary. | .thumb.jpg) |
| Calycine ring | The scar or vestigal calyx-lobes left around the circumference of the fruit at the points where the calyx-lobes (sepals) were attached. |  |
| Calyx-lobes | The outermost whorl of floral parts and nearly equivalent to sepals. See the general glossary for definitions of calyx and sepals. |  |
| Calyx-lobes imbricate | Overlapping of the adjacent edges of the calyx-lobes or sepals. |  |
| Calyx-lobes not imbricate | The base of the sepals do not overlap. |  |
| Canopy tree | A species of tree in which adult individuals occupy the more or less continuous canopy layer of a forest which, in lowland neotropical rainforests, is less than 20 m in height. |  |
| Carpel | The fundamental unit of the gynoecium, often considered to be a folded, specialized leaf. |  |
| Caruncle | An outgrowth or appendage at or near the hilum or near the point where the funicle originates of some seeds, |  |
| Cataphyll | Scale-like bract inserted toward the base of a newly expanded vegetative or reproductive shoot. |  |
| Cauline inflorescence | Refers to flowers or fruits that arise below the leaves from the main trunk of a shrub or tree. |  |
| Centrifugal stamen initiation | A developmental process in which the stamens first initate near the center of the androecium (i.e., around the style) and then progressively toward the outside of the androecium. In other words, the stamens initiate and develop from the inside to the outstide of the androecium. |  |
| Centripetal stamen initiation | A developmental process in which the stamens first initate on the outside of the androecium (i.e., around the edge of the staminal) and progressively develop from the outside to the inside of the androecium. | |
| Cerrado | A Portuguese term referring to a savanna-like vegetation best developed in central Brazil but also found in patches in the Brazilian Amazon and in other South and Central American countries where it is called savanna. |  |
| Chalaza | The part of an ovule or seed opposite the micropyle. In this part of the embryo sac the integument(s) are not differentiated from the nucellus.. |  |
| Chartaceous | With a thick paper texture | |
| Chimera | An animal or a plant with genetically and morphologically different tissue on the same plant. The term is derived from Greek mythology and refers to a mythological animal composed of a lion, goat, and a serpent. Sometimes this term is also used to describe a plant derived from grafting, e.g., stems of Brazil nut trees grafted onto the root stock of another Brazil nut tree resulting in parts of the same tree with different genetic makeups. In Lecythidaceae, we use this term to describe the spontaneous occurence of anomalous flowers on a plant with normal flowers and assume that this difference is caused by a mutation. |  |
| Circumscissile capsule | Referring to a fruit that opens by an operculum. |  |
| Cloud forest | A mid-elevation vegetation type often covered in clouds. Cloud forest is dominated by trees covered with mosses and liverworts. Species of orchids are abundant in this vegetation type and tree ferns are often conspicuous. Depending on local climate, distance from the sea, and isolation from other mountain ranges, cloud forest can be found between 500 and 4000 meters but it is most frequent between 1000 and 2000 meters. |  |
| Colleter | In Lecythidaceae, a multicellular, unbranched glandlike structure found along leaf blade margins. Up to the present only Cariniana estrellensis has been shown to have colleters. |  |
| Columella (pl. = columellae) | A woody outgrowth that descends into the fruit from the interior, middle of the operculum. |  |
| Complanate | 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. |  |
| Concolor (adj. = concolorous) | When two sides of an organ, such as a leaf blade, are the same color. | |
| Coriaceous | With a leathery texture | |
| Cork warts | Very small brown to reddish-brown dots that appear on the abaxial leaf blade surfaces of some species of Lecythidaceae. They are also called punctations in descriptions by various authors. |  |
| Corrugate | Having the suface of an organ wrinkled or wavy. |  |
| Cortex | A band of tissue in a stem or root between the bark and the vascular tissue. The cortex is made of of large, thin-walled parenchyma cells. |  |
| Cortical bundle | A vascular bundle found in the cortex of a stem. |  |
| Cotyledons | Seed leaves, i.e., the embryonic leaves. |  |
| Cotyledons absent (= embryo macropodial) | A massive embryo that shows no obvious cotyledons. |  |
| Cotyledons bowed | Referring to cotyledons that are arched in such a way that they form an air chamber thought to aid in dispersal, either by the wind or by water. |  |
| Cotyledons cryptocotylar | Cotyledons that remain within the seed coat at germination. In the Lecythidaceae the seed coat is thin and fragile and breaks apart as the embryo increases in size. |  |
| Cotyledons epigeal | At germination the cotyledons emerge from the seed coat above the ground. |  |
| Cotyledons fleshy, irregular (= cotyledons plano-convex) | Seed leaves (= cotyledons) that are fleshy and irregular. |  |
| Cotyledons foliaceous (= cotyledons leaf-like) | Cotyledons that look like leaves but differ in their opposite instead of alternate attachment. Same as cotyledons leaf-like which is the preferred term. |  |
| Cotyledons hypogeal | A type of seed germination in which the cotyledons are retained below the ground. |  |
| Cotyledons leaf-like (= cotyledons foliaceous) | Cotyledons that look like leaves but differ in their opposite instead of alternate attachment. | |
| Cotyledons phanerocotylar | A type of seed germination in which the cotyledons emerge from the seed coat at germination.. |  |
| Cotyledons plano-convex (= cotyledons fleshy, irregular) | Same as cotyledons fleshy. We no longer use plano-convex because the cotyledons are very irregular and are not plano-convex as in, for example, the embryo of species of Gustavia. |  |
