iophores sparingly branched, septate ; springing from the com- 

 pact peripheral cells of the stroma. 



Allied most nearly to E. scabriun Corda, in having i -celled 

 conidia ; differing much in the larger polygonal cells composing 

 the stroma, the much longer, branched, septate conidiophores, 



and finally its parasitic habit.

THE HOME OF DUDLEYA RUSBYI 



By H. H. Rusby 



In the North American Flora (22 : 35) the type locality ot 

 this plant is given as " near Prescott, Arizona." The mis- 

 take, perhaps copied from an inaccurate distribution label, 

 should be corrected, especially since the species has been col- 

 lected but once, and under conditions of environment quite dif- 

 ferent from those about Prescott, 200 miles to the northwest. 

 Careful search was made on a number of occasions and in various 

 directions, but only the little cluster of a half dozen plants first 

 collected was ever seen. The plant is apparently a genuine 

 rarity, and this brief description of its locality and habitat is 

 given in the hope of aiding some future collector to rediscover it. 

 ■ At Clifton, Arizona, there was, in 1881, a copper smelter, 

 located close to the right bank of the San Francisco River, and 

 supplied with ore brought by a short railroad from mines owned 

 by the Leszynsky Brothers. These mines were about four miles, 

 as I remember, from the smelter. Several miles beyond them, that 

 is, several miles farther up the canon, were some very rich 

 mines owned by the Metcalfe Brothers, then undeveloped except 

 for so much work annually as the law required for the holding 

 of the claims. These mines were on the north side of the 

 cafion, and included a small mountain of ore rich in native cop- 

 per. Just at the base of this mountain, but in the bank on the 

 opposite side of the canon, was a dug-out hut, built for the 

 accommodation of the prospectors who worked this mine. In 

 this hut I lived in the late winter and early spring of that year, 

 when but few plants had commenced their annual growth. The
