Notes:
The embryo of Neotropical Lecythidaceae is of three types based on the presence or absence as well as the type of cotyledons. Type 1: The cotyledons are leaf-like or foliaceous. This type of cotyledon is found in all species of Cariniana, Couratari, and Couroupita, and some species of Allantoma. Type 2: The cotyledons are thick, fleshy, irregular, and consist of two or more; this type is found in all species of Gustavia. Type 3: In this type the cotyledons are absent and the hypocotyl takes over their role; this type is called a macropodial embryo and is common in all of the zygomorphic-flowered genera except for Cariniana, Couratari, and Couroupita.
