It's a Desmodium (tick trefoil). Not sure of the species. The little triangular segments of the seed pod will stick to clothing, pets, etc.

Two Globularia hybrids are commonly used here: x indubia and 'Blue Eyes'.

Aeschynanthus lobbianus , Lipstick Vine perhaps.

Cypripedium acaule in particular. “Caule” references a stem and the “a” on the front negates it: so it’s the stemless lady slipper. Cypripedium and paphiopedium and phragmipedium and mexipedium are all related in the same subgroup within the orchid family.
