Balansa, 1854, No. 137 in Boissier’s Herbarium, in which there is also a specimen found in the fields in Servia, and a variety with brown beards sent by Pancic, growing in Servian meadows. The same botanist (of Belgrade) has just sent me wild specimens from Servia, which I cannot distinguish from T. monococcum, which he assures me is not cultivated in Servia. Bentham writes to me that T. bœoticum, of which he saw several specimens, is, he thinks, the same as T. monococcum.
