Non-albuminous seeds occur in
Vallisneria
Seeds, which store food materials in their cotyledons are called non- endospermic or exalbuminous seeds.(e.g., gram, pea, bean, almond, groundnut, mustard, sunflower).
Seeds, which store food materials in their endosperm are called endospermic or albuminous seeds. (e.g., castor, maize, wheat, barley, grasses, rice).
Vallisneria is a genus of freshwater aquatic plant, commonly called eelgrass, tape grass or vallis. It has a non albuminous seed.
So, the correct answer is 'Vallisneria'.
