[A] The composite leaves are bright green and toothed, and the tree is in flower between July and November.

The flowers are very small and beige to whitish, are bisexual and group two by two in long racemes.

[1] The concentration of Gevuina avellana in forest is highly irregular and difficult to predict.

[5] The Flora of Australia retains these 2 species in Gevuinia,[6] but the most recent classification places the Australian and New Guinea species as Bleasdalea bleasdalei and B. papuana[7] The seeds are eaten raw, cooked in boiling water or toasted.

[8] The seed has a very high concentration of monounsaturated oils and is also obtained for several purposes in Chile.

[12] It grows well in temperate oceanic climates with cool temperatures where frosts occur commonly in winter, and has thrived in southern New Zealand.

[citation needed] New varieties of greater yield than the original wild stock are being developed in both Chile and New Zealand.

[citation needed] As of 1982, only a tiny fraction of the nuts of wild stands were collected for processing.
