and united at base in front of the filament ; style deeply 2-cleft ; capsule globose, 

 shorter than the calyx, 4-seeded ; seeds punetate-reticuJate. 



Moist sandy spots on granite domes or on rocky slopes in open forest, 4100 to 

 8500 feet : Sierra Nevada from Eldorado Co. to Tulare Co. May-Aug. 



Field note. — Tlie stems or branches of Phacelia eisenii, a somewhat delicate plant, are usually 

 a little flexuous. The racemes are very loose and % to 2% inches long. The initial raceme or a 

 pair of racemes is borne at the very base of the plant, the successive racemes remotely scattered 

 in the axils up the branches to the terminal raceme. The pedicels are often abruptly retrocurved 

 at the very apex.
