A medicinal herb that is native to Pern. In the Northern Continent, it takes the form of small, branchy, drooping trees with fragrant pink flowers. In the Southern Continent, where grubs are well established, the trees are much larger - at Paradise River Hold, Fellis Tree trunks grow larger than 3 men could span with fingers touching. Fellis Trees have clusters of berry-like fruit with tough skins that are boiled and strained to get the juice.
