At least five species of Erigeron were found together at
this locality as follows« E. blooaeri (two collections 974 I
975, the former unusual for the great number of bracts on the
peduncles and subtending the phyllaries; both diploid, 2n=9 II),
E. chrysopsidis (976, rays yellow, no chromosome count), E.
elegantulus (979, blue-rayed triploid, 2n=27), E. linearis (980,
yellow-rayed pentaploid, 2n=ca. 45), and E. pumilis (982, tetra-
ploid, 2n=18 II).

In addition, two putative hybrids resulting from crosses
involving E. elegantulus and E. linearis were collected: 977
with white rays (unfortunately, no chromosome count) and 978
with cream rays (tetraploid, 2n=36).
