jimcea, and Lycopodium Selago, and under overhanging cliffs, the 

 delicate little Saxi/nr^a Careyana. 



The most conspicuous and beautiful of all, except, perhaps, the 

 Rhododendron, is Azalea caletidulacea, with the flame colored blos- 

 soms varying from golden yellow to crimson, and seeming as if the 

 mountain side were on fire. 



Several excursions to Little Roan, four miles away, and of 

 nearly equal height, gave us in addition and in great profusion, 

 Delphinium cxaltatum, Silene Virginiea. Liatris spicata, Rudbeckia triloba, 

 Cirsiuin muticiim, Castilleia coecinea, Fhysostegia Virgiuiana, and Melan- 

 thium Virgiiiicum, with conspicuous white flowers. A tramp of eight 

 miles to Roaring Rock was rewarded with several fine specimens of 

 Aconitiiin recliiiafuni, with blossoms rather more blue than white. 



Cimicifuga raceniosa and Americana are abundant ev-erywhere, the 

 latter a month later, succeeding the former and easily distinguished, 

 even at a distance, by the radiate arrangement of its stamens. 



The most abundant plant is Eiipatorium ageratoides, covering the 

 whole mountain for 2000 or 3000 feet of perpendicular height, until 

 replaced below bv Verbesina Siegcsbcckii. 



The Compositce are well represented in local forms. Solidago 

 spithanuea and glomerata are abundant on j^recipices, moiitieola and 

 piibens in open woods, and Ciirtisii, entirely replacing aesia on the 

 sides of the mountain. Nabaliis Roanensis, n. sp. occurs in the cleits 

 of the rocks 



Aster Curtisii is found on the sides of Iron Mountain, and was 

 noticed abundantlv along the railroad. 



Perhaps the most interesting plant is the rare and beautiful 

 Liliiiin Grayi. The specimens found were well marked, i to 5 flow 

 ered, horizontal, not nodding ; segments not at all recurved nor even 

 spreading: the flowers smaller, more truncate in outline, and much 

 darker than L. Canadeiise. The persistent and careful search of all 

 the botanists, with efficient help from many others, brought to light 

 only 10 specimens, all growing in clumps of Alder or Rhododendron, 

 and thus protected against cattle, sheep and hogs, those enemies of 

 all botanists, who bid fair at no distant time to exterminate it from 

 Roan. It is to be ho]:)ed that the Peaks of Otter, its other known 

 locality, may not be thus ravaged. 



Abies Eraseri m plentiTul near the summit, and very consi)icuous 

 with its abundant erect fringed cones. 



The turf is of a most vivid green even in August, and seems to 

 be made u]) of Fm annua, Danthonia comprcssa, and perhaps some 

 early flowering Carices Poa compressa occurs on Little Roan. 



Several moUusks have been detected on the mountain, by Mrs. 

 Andrews, either very rare, or unknown elsewhere. 



A trip to Bakersviile, ten miles away, was rewarded by Helian- 

 thus microcepluilus and atrorubens, and Euphorbia Lathyris, the latter 

 thoroughly naturalized along the roadsides and very conspicuous. 



Of most of the species enumerated above I have an abundant
