Mannans, in which mannose units are linked predominantly in j8-d-(1—>4) bonds, are found in the red seaweed Porphyra umbilicalis, in the seed of the tagua palm (Phytelephas macrocarpa) in the form of massive thickening of the cell walls of the endosperm, and in the endosperm of members of the Umbelliferae and of the Compositae (e.g., lettuce seed). 

Ivory nut IHie nutlike seed of e South American oalm (Fhytelephas macrocarpa). It is as large as a hen s egg and contains a very hard endosperm, which under the name of vegetable Ivory, Is used for turning and carving, as for buttons, etc.

Palmyra pahn (Borassus flabellifer), galactoman-nans e.g. lucerne (Medicago sativa), seeds of Sesbania aegyptiaca, glucomannans e.g. white spruce (Picea glauca), Larix decidua, jack pine (Pinus banksiana), Bletilla striata and Narcissus tazetta.
