| Abstract: | Isoetes xbruntonii is the hybrid between the diploid I. engelmannii (2n = 22) and the tetraploid I. hyemalis (2n = 44). An apparently sterile triploid (2n = 33), it has megaspore features intermediate between the two parents, but does not exhibit hybrid vigor. Isoetes xbruntonii is frequent at localities in the outer Coastal Plain of Virginia. |
