Answer:

The orthotropous ovule is found in Pinus.

Explanation:

The pine tree is heterosporous in nature. It bears ‘male and female’ cones on the same tree during the spring season. They bear spirally arranged closely packed sporophylls around a central axis. The sporophylls of the female cone have a lower bract and a larger bract scale.  

The larger ovuliferous scale bears two ovules side by side and this arrangement is called as orthotropous ovule. The ovules produce 4 megaspores by meiosis but only one matures.
