Answer

**Step-by-Step Solution:**

1. **Identify the Organism**: The question refers to Ophioglossum, a type of fern known for having a very high chromosome number.

2. **Understand Chromosome Numbers**: The somatic chromosome number mentioned in the question is 1262. We need to verify if this number is accurate for Ophioglossum.

3. **Research Historical Data**: Historically, Ophioglossum has been noted to have one of the highest recorded chromosome counts in the plant kingdom. The diploid number is often cited as 1260.

4. **Examine Current Understanding**: Recent studies have indicated that the chromosome number may vary, with some reports suggesting counts of 1520 chromosomes in certain species of Ophioglossum.

5. **Conclusion**: Based on the historical data, the statement claiming that the somatic chromosome number in Ophioglossum is 1262 is incorrect. The more accepted figure is 1260, making the statement false.

**Final Answer**: The statement is false; the somatic chromosome number in Ophioglossum is 1260, not 1262.
