13. L. rivularis Dougl. Canon Lupine. Nine Finger. Stems erect, several 

 from the root-crown and forming a clump, branched above, usually red-brown, 

 2 to 5 feet high ; herbage minutely appressed-pubescent or glabrate ; lower leaves 

 long-petioled, usually withered by flowering time, the middle leaves largest; leaf- 

 lets commonly 7 to 9 (5 to 12), oblong-oblanceolate, mostly acute, 2 to 6 inches 

 long ; racemes 8 to 18 inches long, rather lax ; flowers 5 to 7 lines long, whorled or 

 scattered; pedicels 1 to 3 lines long; petals light blue, purple or pink, rarely yel- 

 lowish, fading brown; keel somewhat exposed, arcuate (almost right-angled), 

 ciliate on upper edges at middle, or from middle to claws ; pods dark brown, densely 

 hairy, about 1^/4 inches long; ovules 7 to 10; seeds mottled with dark brown. 



Open woods or thickets, hillslopes or canons, 100 to 7200 feet : coastal region 

 from Los Angeles Co. to Humboldt Co. ; Sierra Nevada from Tulare Co. to Modoc 

 Co. South to Lower California, north to Washington. Apr.-May. 



Tax. note. — The type of Lupinus rivularis Dougl., a species published by John Lindley, is 

 presumably preserved in the Lindley Herbarium, Cambridge University, England. Four sheets 

 from that herbarium (which concern matters at issue) have been studied. We annotate them as 

 follows: First is a sheet with the label "Herb. Soc. Hort. Lond. America boreali-occiden talis. 

 Douglas 1830." This specimen is chosen as the type. Its origin is unquestionable. We may 

 confidently believe it the plant named Lupinus rivularis by Douglas. The sheet bears an annota- 

 tion by Asa Gray: "I suppose the wild of L. rivularis Lindl. (non Ag.). A G." The term "America 

 boreali-occidentalis", northwest America, in the case of Douglas plants, means almost invariably 

 Oregon or Washington. The indication "California" by Lindley (Bot. Eeg. t. 1595), as to origin 

 of the Douglas plant, was doubtless an error, or used in the extended and loose sense of that early 

 day as applying to the region stretching nearly or quite to the Columbia Eiver. Moreover, and 

 quite conclusively, Douglas was exploring the present territory of Oregon and Washington in 

 1830 and did not arrive in California (Monterey) until December 22 of that year. His specimen 

 is a flowering one. 



Specimens from Montesano, Wash. (Seller 3906), match the type sheet rather closely. In 

 pubescence and shape and size of leaflets the following Calif ornian plants come rather close: 

 Alton, Humboldt Co., Tracy 6376; St. Helena, Jepson 26t; Crystal Springs Lake, San Mateo 

 Co., C. F. Baker 470. 



The general appearance of the specimen in the Lindley Herbarium, here taken as the type, 

 is strikingly like the illustration accompanying the original diagnosis (Bot. Eeg. t. 1595). The 

 resemblance holds as to foliage, inflorescence and flowers. The leaflets are 5 or 6 to 8, exactly 

 oblanceolate, 1 to 1% inches long, shortly apiculate, glabrous above, strigulose below, the margins 

 usually hairy. The stems have a thin pubescence of fine short ascending hairs. The pedicels and 

 calyx are more densely pubescent than the stem. The lower calyx-lip is narrow and long, and 

 strongly keeled as far as the entire apex ; the upper lip is narrow, keeled and notched at apex. 



Second is a sheet which has no label and appears to be, without reasonable doubt, a duplicate 

 of the sheet first mentioned. 



Third is a sheet with the label "California. Douglas", the label being the light blue label or 

 ticket so commonly used by Douglas. The sheet bears also a label with the note "Lupinus rivu- 

 laris B E. 1595" apparently in the hand of J. G. Agardh. There is also an annotation by Asa 

 Gray in his scarcely decipherable hand: "not Lupinus rivularis B E 1595. Agardh is wrong, 

 but = L. arboreus!! A. G." Asa Gray's determination is quite correct. The sheet also bears a 

 specimen of Lupinus arboreus collected by Coulter, in California, the label carrying the name 

 Lupinus rivularis Liudl. These specimens may well have been collected at Monterey, possibly at 

 the time when Douglas and Coulter botanized together near the old Spanish capitol.
