tiinetor^, long and slight!}' exceeding the flower-eluster ; calyx coniiiionly 7 

 to i» niiliinieteris long, with the [dicate sinuses characteristic of tiie genus, 

 the lohes equalingthe tube, triangular-lanceolate, acuminate, in fruitreach- 

 ing a length of 5 or 6 luillimetens ; corolla about 15 millimeters long, deep 

 blue to violet-[)ui-i)le, above the calyx exjianding into a funnel-shaped 

 throat, the narrowly ol)loiig-obovate obtuse moderately divergent lobes 

 about 5 millimeti'rs in length ; stamens slightly exserted, the anthers white, 

 the filaments of somewhat unequal length, but inserted almost equally 

 about halfway from the sinuses to the base of the tube; ovule single in 

 each cell of the ovary ; style also exserted, the stigma 3-lobed ; capsule 

 al)out half as long as the fruiting calyx, narrowly obovate, truncate or de- 

 pressed at the three-lobed summit, loculicidal in dehiscence, the 3 valves 

 partially breaking away from the axis; seed about 3 millimeters long, 

 olive-brown at maturity, linear-oblong, obtuse at l)oth ends, sulcate on 

 the axial fiice and attached to the placenta for ahjiost its whole length, 

 dull i)ut without distinct markings, developing the characteristic spiracles 

 of CoUomia in water. 



Type specimen in the United States National Herbarium, collected Au- 

 gust b3, 1896, near Crater Lake, in the Cascade INIountains of Oregon, at 

 an altitude of l.ilOO meters, by Frederick V. Coville and John B. Leiberg, 

 No. 429. 



This showy luid beautiful Collomia is remarkable for its peren- 

 nial habit and tlie dee}) violet-lilue color of its flowers. The 

 glandular hairs of the calyx and peduncles give oflf the odor 

 characteristic of most of the Collomias and some of the Phacelias. 

 The only other blue-flowered, perennial species of the genus is 

 Collomia deb Ills (Wats.) Greene, a variable plant, first collected in 

 southern Utah, later in western Montana, the Cascade Mountains, 

 and tlie nortliern 8ierra Nevada, one or more of its various forms 

 probabl}'' susceptible of varietal or specific separation. 



The plant grows in abundance in slightly moist, open, spar- 

 ingly grassy places in the forest, in the vicinity of streams and 

 wet meadows, about five kilometers west of the U2:)per camping 

 ground at Crater Lake, and continues southeastward at about 

 the same altitude, at least as far as the lower camping ground, 

 about two and a lialf kilometers south of the rim of the lake. 

 For one starting from tlie junction of the Rogue River and Fort 

 Klamath roads and traveling northward toward Crater Lake, 

 the most convenient and iirobably the first i)lace for finding the 

 plant is on the fiat ground where the road first crosses the stream 

 on which the lower cam[)ing ground is situated. Specimens 

 were seen here, but not in abundance. At the time of collect- 

 ing, the species was in full [lower, nnd very few of the specimens 

 had prodiice(l mature seeds.
