T. monticulum / T. pusillum var. monticulum if recognized.
In only a few clusters here; one larger colony nearby, but not numerous and absent from seemingly suitable habitat nearby.
(Not a new site.)
Nearly every plant lacking an unambiguous pedicel, but I did find at least one cluster with a very short (< 3 mm) pedicel.
I have seen at least one person describe these mountain populations as growing in "high elevation swamps". This was not the case here. They were all in well-drained sites, quite dry in mid-spring.
