Bloomeria aurea Kell. Same range as the last. 



Brodiaea capitata Benth. Ranging up into the lower part of the pine belt, fre- 

 quent at lower levels. 



Smilacina sessilifolia Nutt. Common in springy ground near the head of Cold- 

 water Fork of Lytle Creek, alt. 7000 ft. Upper Transition Zone. (No. 1448.) 



Yucca Whipplei Torr. This common valley species ranges well into the Transi- 

 tion Zone. One plant was noted at 8200 ft. alt. on the steep south slope of 

 Ontario Peak. 



Lilium Parryi Wats. Very common at 7000 ft. alt., Upper Transition Zone, in a 

 small side canon of Prairie Fork. (No. 1703.) 



Lilium Humboldtii Roezl. & Leicht. A few plants along streams in the lower part 

 of the Transition Zone. 



Fritillaria atropurpurea Nutt. var. pinatorum (Davids.) Johnston, comb. nov. 

 F. pinetorum Davidson. A single plant of this species was collected at the 

 Old Hydraulic Mine, growing at 7750 ft. alt. in decomposed granite on a north- 

 facing slope. Another single plant was found growing in a similar habitat 

 at 7250 ft. alt. in Icehouse Canon. Both stations are in the Upper Transition 

 Zone. Dr. Hall (No. 1504) collected the plant in Swartout Valley at 6000 ft. 

 alt. 



This variety is distinguished from the species by its erect pedicels, slightly 

 smaller flowers and stouter habit of growth. 



Calochortus invenustus Greene. In decomposed granite in the Upper Transition 

 Zone. Frequent. (Nos. 1397, 1606.) 



IRIDACE.E 



Sisyrinchium oreophilum Bickn. Common in springy places in the Upper Transi- 

 tion Zone. Not seen lower than 6500 ft., nor higher than 8200 ft. alt. Cer- 

 tainly distinct from the valley form, being smaller, more slender and un- 

 branched; the fruit is smaller and thinner walled; the flower is smaller and 

 much darker in color. A good variety at least. Det. E. P. Bicknell. (No. 

 1409.) 



ORCHIDACE^E 



Corallorhizamultiflor a Nutt. Seen at three stations. At Kellys Cabin, the lar- 

 gest colony, the plants were growing in rich moist ground under the pines at 

 8250 ft. alt. A single plant was found in a rotting pine log on the saddle be- 

 tween Baldy and Pine Mt. Another individual was seen under the pines at 

 8750 ft. alt. on the west spur of Baldy. All these stations are in the upper- 

 most part of the Transition Zone. (No. 1669.) 



Limnorchis sparsiflora (Wats.) Rydb. Frequent in marshes in the lower two- 

 thirds of the Transition Zone. Highest seen at 8000 ft. at the Old Gold 

 Ridge Mine. Our lower station is the marsh below Camp Baldy, where it is 

 very common at 4200 ft. alt. in the Upper Chaparral Belt. (No. 1433.) 



Epipactis gigantea Dougl. With the last in the pine belt, but extending to much 

 lower levels, reaching the foothills and valley. (No. 1529.)
