specimens heretofore referred to A. flavescens Watson with long 

 slender stems, small flowers and reduced leaves. 



AQUILEGIA CvERULEA VAR. FLAVESCENS (Wat.) (A. JtoVeSCeilS 



Watson Bot. Kinsr v 10.) 



There is a complete transition from flavescens through 

 caerulea to chrysantha. Most of the species of Aquilegia are 

 little more than soil and moisture varieties of two or more poly- 

 morphous species. 



Aquilegia Formosa var. desertorum. Delicate slender 



plants growing in the crevices of rocks near springs, about a 

 foot high, stems flexuous; radical leaves rarely over }i as long 

 as the stems, small, biternate; primary divisions of petiole i to 

 ij4 inches long, the central one-half longer, secondary divisions 

 1 to 6 lines long the central one twice the lateral ones and 

 filiform; petioles dilated only at very base; nodes 2 to 3 inches 

 apart; upper petioles reduced to rudiments and with primary 

 divisions filiform, 6 to 12 lines long, the secondary divisions 1 

 to 2 lines long, or only the central one present and leaflets 

 either 3-lobed or incised and divisions 1 to 3-toothed, all leaflets 

 about 6 lines long, deeply incised, usually broadly cuneate- 

 obovate, or when parted the divisions are of this shape; upper- 

 most bract generally3-lobed with oblong lobes 2 to 3 lines long- 

 Whole plant rather glaucous, glabrous except the upper inflores- 

 cence which is glandular-hairy. Peduncles 2 to 3 inches long 

 in fruit, 5 to 10, rarely branched, flowers red, nodding, 15 

 lines long; filaments 5 lines long; sepals dark, elliptical- 

 lanceolate, 4 lines long, spreading but not reflexed; blade of 

 petals rounded, about as long as wide, 2 lines long, fully as 

 wide as sepals, yellow; spur 8 lines long, the lower half linear 

 and nectary well developed, straight; pods erect, 8 lines long ex- 

 clusive of the long and filiform spreading styles (4 lines long), 

 nervose, membranous; seeds black and shinning, about ^ 

 line long. Collected at Flagstaff, Ariz., Aug. 29, 1884. 



ESCHSCHOLTZIA MINUTIFLORA VAR. DaRWINENSIS. A foot high, 



freely branching toward the top; leaves nearly all radical, stem 

 leaves reduced to mere rudiments; peduncles usually shorter 

 than the 2-inch-long, slender capsules; torus turbinate, with
