If you are talking about Asian rice, it is all the same species, just different varieties. In fact there are 1000's of varieties of rice grown in both upland and lowland systems. Lowland rice is grown in fields that can be flooded and they are either rain-fed or irrigated. Upland rice is grown without flooding usually on hillsides in more mountainous regions. Different countries and regions have their own preferences for varieties of rice.
