Description:
Apparently a nucellar selection of C hystrix. Source of seed unknown, possibly from other C hystrix accessions (CRC 2454/PI 539248; CRC 3103/PI 539249). Both of these were received before the date of the nucellar block planting (1972). This would make sense as the nucellar selection would be a way to achieve a clean source prior to Thermotherapy or STG. However, this is conjecture.
