lower leaflets petiolate and often deeply lobed; fruit orbicular, 2 mm. 
long, the narrow ribs approximately equal (in section as well as in 
surface display), leaving broad intervals and large oil tubes, which are 
sunk in the channeled seed. 
Type locality, ‘Sat Suisun, California, in salt marshes;” collected by 
Bolander; type in Herb, Gray.

CaLiFoRNIA: In Suisun Marsh, Greene, September 29, 1889. 
In describing the habitat of this very local species Professor Greene says (Pittonia 
2:7. 1889): ‘‘ Very plentiful about Teal Station in the midst of the Suisun Marsh, and 
also near Martinez on the opposite side of Suisun Bay, growing among tall reeds and 
sedges in a hard but coarse and loose sod, the roots and base of the stem laved daily 
by the brackish tide water.”’

largest in section, but not wedge-shaped or closely contiguous; dorsal 
and intermediate ribs about as broad as the intervals; oil tubes large.
