2. A. tracyi Jepson. Similar to the preceding; puberulent and viscid 

 throughout, especially on the stems; upper leaves reduced to small bracts; 

 flowers larger and stamens longer; sepals retlexed ; petal spurs usually spread- 

 ing more widely, the throat nearly twice the ciiameter of the throat in no. 1, 

 and with its orifice cut backward obliquely and not horizontall}' ; styles very 

 long. 



Rocky places along streams. North Coast Ranges from Marin to Napa and 

 ilendocino cos. Also, apparently, in a glabrous form in the Santa Cruz Jits. 

 Rare. June-Sept.

3. A. formosa Fisch. Stems l^o to 3 feet high; flowers crimson to scarlet; 

 sepals 8 to 10 lines long; petal blades yellow, truncate, about % to i^ the 

 length of the crimson spurs which nearly or quite equal the spreading sepals; 

 follicles 10 to 14 lines long.

4. A. pubescens Cov. Stems 9 to 18 inches high ; leaves minutely soft- 

 pubescent or <|uite glabrous; leaflets small (4 to 6 lines long), cleft and crenate 

 at apex; flowers erect, cream yellow, varying occasionally to white or to shades 

 of red, pink or purple ; sepals oblong-ovate to ovate. 7 to 11 lines long. 4 to 5 

 lines broad; petal-blades obtuse, 4 to 5 lines long, their spurs 11 to 13 lines 

 long. 



Alpine, in rocky places, 9000 to 12,000 feet: Sierra Nevada from Tulare Co. 

 to JIariposa Co. The typical pubescent form occurs south of Kings Cation ; 

 the specimens received by us from north of Kings Caiion are glabrous or 

 nearly so.

7. DELPHINIUM L. Larkspur. 



Herbs, ours perennial, with palinately divided leaves. Flowers in terminal 

 racemes. Sepals 5, irregular, the upper one produced into a spur at the base. 

 Petals 4, in unequal pairs, with small spreading usually oblique blade on a 

 claw of about equal length, the upper developed backward into nectary- 

 bearing spurs, which are concealed within the spur of the calyx. Pistils (in 

 ours) 3, seldom more, becoming many-seeded follicles. — Species about 200. 

 North America. Europe. Asia and Africa, (Greek delphinion, larkspur, derived 

 from delphin, the flowers of some species resembling the classical figiu'es of the 

 dolphin,) 



The upper pair of petals are smaller tluiu the lower, usually whitish, rarely 

 yellowish, lavender, or bluish, very obliquely 2-lobed, the longer lobe com- 

 monly notched or emarginate; lower pair commonly the same color as the 

 sepals, limb slightly or deeply cleft (even in the same species), the upper sur- 

 face with a central tuft of hairs, or ciliate, or the whole surface more or less 

 hairy, but in this respect variable, even in one species. The species are difficult
