This species has long been attributed to Mon- 

 terey: by Brewer and Watson, Bot. Cal. 1:32,-1876; 

 by Gray, Syn. Fl. 1»: 161,— 1895; and by other au- 

 thors following them, including the present writer. We have, however, never collected it at 

 Monterey and there are no specimens of it from Monterey Co. in the herbaria at Berkeley, Stan- 

 ford or Pacific Grove, and we have no definite modern record of the occurrence of this species on 

 the Monterey Peninsula. 



Var. macdonaldiana Jepson. Stems 3 to 5 inches high, several from a branched caudex; 

 herbage glabrous; petals oblanceolate, truncate, 4 lines long; stamens with broad filaments, 

 the upper and lower pairs exceeding the sepals, the lateral pair much shorter. — Northwestern 

 Mendocino Co.

In the Botanical Magazine (t. 6087) J. D. Hooker cites San Francisco as the station for the 

 Douglas collection, but there is no locality given on the original Douglas spm. (Herb. Hook., 

 Kew). Search at Kew and elsewhere gives no evidence that a definite station is known for any
