SB 5.20.8
yatra ha vai salmali plaksayama yasyam vava kila nilayam ahur bhagavatas chandah-stutah patattri-rajasya
sa dvipa-hutaye upalaksyate.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
On Salmalidvipa there is a salmali tree, from which the island takes its name. That tree is as broad and tall as the plaksa tree — in other words 100 yojanas [800 miles] broad and 1,100 yojanas [8,800 miles] tall. Learned scholars say that this gigantic tree is the residence of Garuda, the king of all birds and carrier of Lord Visnu. In that tree, Garuda offers Lord Visnu his Vedic prayers.
