 Numerous ("aliforinan specimens have been referred to this species, which seem to 

 iK^long more ])roiierly cither to //. imdwlhttn or //. nnicdta. Specimens from wet land 

 on the shore of Silver Lake, near Tucson, An/.. {I'rimjle in 1881 and Deirey in 1891), 

 seem to represent a form of this species, in which the axis of inflorescence i.s elon- 

 gated, the whorls being distant and few-(lowered, and the pedicels are longer than 

 we have seen in Californian specimens. We have not Ix'en able to confirm the state- 

 ment that the species occurs in Texa.s and Mexico.
