The Procedure of Sr&ddha Performance - Verse 74-75

The Aloe wood is to be desired by all. It has the same benefit as that of a horse-sacrifice. The following trees should be avoided— Slegmataka, Naktamala, Kapittha, Salmali, Nipa, Vibhitaka and the creepers also. Similarly the trees on which birds reside must be avoided. Those trees which are considered unworthy of sacrifice should also be avoided.
