Notes:
Collected in French Polynesia, in the Marquesas on Nuku Hiva Island in A'akapa Valley. The name "Mei Kopumoko" refers to a "shark's thorax." The fruit is hard to cook and is traditionally pricked with a piece of wood to soften before cooking. It is considered an old variety of breadfruit and grows in both Hatiheu and A'akapa Valleys.

Geographical Information
Geographical information associated with living collections accessions at botanical gardens includes details on the native origin, collection site, and habitat of each plant. This data helps track the genetic diversity, ecological preferences, and conservation status of species. Accurate geographical records support research, restoration efforts, and the cultivation of plants in environments similar to their natural habitats.
Morphological Measurements
Measurements were taken 10 times for each tree or group of trees of a particular variety, using 10 individual fruits, male flowers, and leaves, respectively (Ragone & Wiseman, 2007). The following were selected for measurement:
Leaves: The third fully expanded leaf from the tip of a mature branch.
Fruit: Mature, firm, but not yet ripe fruit.
Male Flowers: Fully emerged male flowers.
Seasonality
Over a 10-year period, fruiting seasonality was observed in the breadfruit collections at Kahanu Garden (Maui) and McBryde Garden (Kaua‘i) within the National Tropical Botanical Gardens (Liu et al., 2014). Tree canopies were visually examined for the presence of full-sized, mature, and ripe fruit.
Full-sized fruit: Fruit at maximum size but not yet mature.
Mature fruit: Fruit displaying distinctive characteristics of maturation.
Ripe fruit: Fruit that were soft and ripe on the tree.
