y LUPINUS ADSURGENS Drew, Bull. Torr. Club IG: 150. 1889. 

 According to Greene, Flora Franciscana 41, this is a syno- 

 nym of L. latifoliiis. It was originally collected in northwest- 

 ern California, in Humboldt county. The description is so 

 vague that it might be any oue of a dozen well known species. 

 The flowers are said to be light yellow, an unusual color for this 

 group. 



LupiNus CYTisoiDES Agardb, Syn. 18. 1835. 

 Collected in California by Douglas, perhaps in the neigh- 

 borhood of Santa Barbara, which place was the southern limit 

 of his journey in California. The species is not well known, 

 but is evidently distinct from latifolius. 



LUPINUS LATIFOLIUS Agardh, Syn. 18. 1835. 

 Also collected in California, and probably near Monterey. 

 Recent specimens from the vicinity of Monterey seem to corres- 

 pond fairly well with the original. One of them is my 6680^ 

 collected near Del Monte in 1903. 



LupiNUS viRiDiFOLius Heller, Muhlenbergia 2: 64. 1905. 

 Northern California on the upper Sacramento river. 



This section is confined to the Pacific slope, the species 

 usually occurring at rather low altitudes. L. con/usus is the 

 only one thus far recorded from the eastern side of the great 

 mountain range which separates the Pacific coast region from 

 the dry interior, but its presence there can be accounted for by 

 the fact that a gateway is found for the distribution of such spe- 

 cies along the Columbia river, a condition not found at any point 

 south of this stream. 



Arborei Agardh, Syn. 24. 1835. 

 This is Agardh's tribe H., which he describes as having 

 "stems decumbent and persistent, the calyx ebracteolate, deeply 

 bilabiate, keel ciliate." He also describes Z. arboretts as having 

 a sub-frutescent, decumbent stem, which is [never the case, as it 

 is always distinctly woody, and is certainly never normally de- 

 cumbent. However, nearly all of the species are decumbent at 

 the woody base. The flowers are among the largest in the
