 a line or less long, erect: calyx-segments linear, longer than the nutlets, 

 spreading but not enlarged in fruit, hirsute with ferruginous hairs when 

 young: corolla 1-2 lines in diameter; the appendages in its throat not con- 

 spicuous : nutlets ovate-oblong, slightly carinate ventrally, transversely

A. Chorisiana Greene Pitt, i, 13. Pubescence sparse and appressed 

 except on the calyx: stem 1-2 feet high, freely branching, the branches at 

 length recurving': larger leaves 2-4 inches long : racemes elongated, loose 

 and leafy below: pedicels filiform, 4-8 lines long: calyx little accrescent, 

 the campanulate segments about a line long : corolla 3-5 lines broad : nut? 

 lets ovate, little more than half of a line long, carinate ventrally only, the 

 keel and scar closely approached but not covered by the lateral angles, the 

 obtuse rugae of the back running into more or less favose meshes among 

 minute granulations. On Vancouver Island B. C. and at San Francisco 

 Bay California, perhaps at intermediate stations. 



A. hirta Greene 1. c. 161. Setose-hispid throughout with spreading 

 or somewhat deflexed hairs and no appressed pubescence: stem erect and 

 stoutish, 10-16 inches high, simple below with several pairs of connate- 

 sheathing linear leaves, loosely racemose above: racemes in pairs, bract- 

 less : pedicels slender, a line long : calyx 2 lines long, not enlarging in fruit. 

 its segments erect in fruit, very hirsute : corolla 3 lines broad : nutlets 

 ovate, dark-colored, scarcely carinate except ventrally, the dorsal face 

 granulate and obscurely rugulose. In wet places, Umpqua Valley Oregon. 



A. Sconleri Greene 1. c. 18. Eritrichiim, Scouleri A. DC. Sparsely 

 appressed-hirsute : stem 6-18 inches high, usually diffusely branching from 

 the base with slender ascending branches and few pairs of connate-clasp- 

 ing linear leaves: flowers in geminate, or sometimes paniculate slender 

 racemes, most of them bractless, very fragr^t : pedicels erect or ascending, 

 at most a line long: calyx erect and not enlarged in fruit; corolla 3-4 lines 

 broad, the appendages in the throat conspicuous, yellow, puberulSnt : nut- 

 lets ovate, %] line long, carinate on both sides at the apex and ventrally 

 down to the linear-oblong scar, dorsal surface obviously granulate and in- 

 distinctly rugulose. Common in wet places, western Oregon and Wash. 



A. Hendersoni A. Nelson Eryth. vii, 69. Sparsely and rather softly 

 strigbse-pubescent throughout : stem simple at the base, sparingly branch- 

 ed above, erect, slender, 8-16 inches high : leaves brci'adly linear, 2-3 inches 

 long, acutish : racemes naked, at length long and slender, the uppermost 

 geminate with a flower in the fork : pedicels short : calyx-segments linear, 

 in fruit about 2>g lines long, strigose-hispid : corolla 2)^-3 lines in diame- 

 ter, the throat nearly closed by the conspicuous emarginate appendages : 

 nutlets ovate, subacute, 1-1 J^ lines long, very closely and finely miiriculate, 

 with a few small rounded papillse interspersed, moderately carinate on the
