timeters long and slightly exceeding the flower-cluster ; eal yx commonly 7 

 to 9 millimeters long, with the plicate sinuses characteristic of the genus, 

 the lobes equaling the tube, triangular-lanceolate, acuminate, in fruit reach 

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

 blue to violet-purple, above the calyx expanding into a funnel-shaped 

 throat, the narrowly oblong-obovate obtuse moderately divergent lobes 

 about 5 millimeters 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 

 about 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 both ends, sulcate on 

 the axial face and attached to the placenta for almost its whole length, 

 dull but without distinct markings, developing the characteristic spiracles 

 of Collomia in water. 



Type specimen in the United States National Herbarium, collected Au 

 gust 15, 1896, near Crater Lake, in the Cascade Mountains of Oregon, at 

 an altitude of 1.900 meters, by Frederick V. Coville and John B. Leiberg, 

 No. 429. 



This showy arid beautiful Collomia is remarkable for its peren 

 nial habit and the deep violet-blue color of its flowers. The 

 glandular hairs of the calyx and peduncles give off 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 <&&#& ( Wats.) Greene, a variable plant, first collected in 

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

 and the northern Sierra Nevada, one or more of its various forms 

 probably 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 upper 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 half kilometers south of the rim of the lake. 

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

 Klamath roads and traveling northward toward Crater Lake, 

 the most convenient and probably the first place for finding the 

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

 on which the lower camping ground is situated. Specimens 

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

 ing, the species was in full flower, and very few of the specimens 

 had produced mature seeds.
