Abstract：Ampelocalamus microphyllus and A. luodianensis are climbing shrubby bamboo species with high ornamental value. There are no enough records of the morphological characteristics of their flower and fruit in the existing literature, leading to the disputes in their taxonomy. The authors observe carefully and record the morphological characteristics of their flower and fruit during the flowering and seeding periods at their original habitats, and collect the seeds and determined their nutritional components. The results show that:1) The flower and fruit of the two species have similar morphological characteristics. The main distinction is that A. microphyllus has more veins on its lemma and shorter stalk on the back of the glumelle than A. luodianensis; 2) The seed of both A. microphyllus and A. luodianensis are rich in protein, polysaccharide, carbohydrate and mineral elements, especially calcium, magnesium, potassium, copper, iron, zinc and manganese, which can be used as edible plants. The selenium content in A. microphyllus seeds meets the standard of selenium rich food and therefore can be used as selenium rich food.
