Brassicaceae Steptanthus inflatus

Squaw Cabbage (Streptanthus inflatus) along the Grass Valley Route.

A portion of the Grass Valley Route threads the boundary between the China Lake Naval Weapons Station and the Grass Valley Wilderness. This portion is known informally as the "Northwest Passage" as it is the only route through this area and avoids a lengthy detour. The Navy has built a stout barbed wire fence along the border, with a ditch and a berm just inside. These Squaw Cabbage (Streptanthus inflatus) have found the berm to be a preferred habitat, and are very grateful to the Navy.

In Weber & Wittmann (2012), keys directly to R. sphaerocarpa in Brassicaceae Key A at couplet 17, then gets lost at couplet 5 in their key to Rorippa, over the question of whether the plant is erect or decumbent. In Ackerfield (2015), keys fairly easily to R. palustris, the only question being whether the stem is hirsute. In Harrington (2nd ed., 1964), keys easily to R. islandica, for which Harrington gives R. palustris as a synonym.

In Weber & Wittmann (2012), keys directly to R. sphaerocarpa in Brassicaceae Key A at couplet 17, then gets lost at couplet 5 in their key to Rorippa, over the question of whether the plant is erect or decumbent. In Ackerfield (2015), keys fairly easily to R. palustris, the only question being whether the stem is hirsute. In Harrington (2nd ed., 1964), keys easily to R. islandica, for which Harrington gives R. palustris as a synonym.
