जातकम् १
विप्रलैस्तनुचंद्रेज्यार्कैस्तरूणां जनिं वदेत् ।स्थलांबुभेंदोशकृतश्चेतरेषामुदाहृतः ॥ ३७ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 37.
When the lagna (rising sign), the Moon, Jupiter and the Sun are weak, tell the birth of trees. Whether a tree is of land or of water comes from the navamsha (one-ninth part of a sign). The same is said for the others. (Our text is unclear here: the word read as 'weak' is damaged.)
Simple meaning: A weak lagna, Moon, Jupiter and Sun point to trees. The navamsha shows land or water trees.
स्थलांबु च पतिः खेटो लग्नाद्यावन्मिते गृहे ।
The number of trees is told by how far the planet stands from the lagna.
अंतःसारा रवौ सौरे दुर्भगाः क्षीरिणो विधौ ।
Each planet shows what kind of tree: the Sun hard wood, the Moon milky, Mars thorny.
पुष्पिता भार्गवे स्निग्धाश्चंद्रेऽथ कटुकाः कुजे ।
Venus gives flowering trees. The Moon gives oily ones and Mars bitter ones.
