L. virginicum vs. L. densiflorum

L. densiflorum obovate fruit, petals not obvious, sometimes really long, dense racemes (hence the name), and I think the elongating racemes have tighter clusters of flowers at their head than does L. v.. I still have a hard time with these two species.

L. acutidens vs. L. oxycarpum

In 1925 Jepson named a plant Lepidium oxycarpum var. acutidens (A. Gray) Jeps.
Makes me wonder if he thought these two species were not too distinct...

Species I have trouble distinguishing

L. strictum from L. oblongum
L. nitidum from L. virginicum in Southern CA
L. oxycarpum from L. acutidens

Lepidium nitidum anther #

Jepson Flora CA says it has 4 anthers, Flora North America says it has 4 or 6. Ihsan Al-Shebaz did both treatments. Here is an observation with a definite L. nitidum (flat pedicel) showing 6 anthers, so I guess 4 or 6 is right. https://www.inaturalist.org/observations/39395108
