 the mountains of Colorado, while the range of E. Dnnniiiondii ex- 

 tends further north.

Epilobium Palmeri sp. nov. 



Perennials propagating by turions or occasionally with more 

 leafy rosettes ; stem 4-6 dm. high, branched, glandular pilose, 

 nearly terete, usually reddish or brownish ; leaves sessile or nearly 

 so, ovate or ovate-lanceolate, rounded or obtuse at the base, acute, 

 denticulate, 3—4 cm. long, more or less pubescent ; petals pink or 

 light purple, about 5 mm. long ; pod 4-6 cm. long, 1.5 mm. thick; 

 seeds brown, more or less papillose, without a beak ; coma white 

 or in age somewhat tawny, 6-8 mm. long. 



The type was named E^. tetragonuni L., which species is not 

 found in the United States. It resembles much E. brevistyhim and 

 E. ovatifoluiin in habit, but is characterized by the pubescent stem 

 and leaves.

Gayophytum intermedium sp. nov. 



Profusely branched glabrous annual ; stem white and shining, 

 with more or less peeling bark, 3-7 dm. high, erect; leaves linear 

 or nearly so, light green ; sepals about 1.5 mm. long, soon spread- 

 ing or reflexed, yellowish; petals 1.5—2.5 mm. long, ro.se with 

 yellow base ; capsule 8—12 mm. long, nearly twice as long as the 

 reflexed pedicel, somewhat clavate and torulose, somewhat 

 strigose when young; seeds 1.75 mm. long, glabrous. 



This species is intermediate between E. dijfusnin and E. raino- 

 sissiiimm in some respects. The flowers approach the latter more 

 in size but the former in coloration. The pod is comparatively 

 longer than in either. In both it is scarcely longer than the 

 pedicels. E. intermedium grows in sandy soils in Colorado at an 

 altitude of 1,500-3,000 m.
