BOTANICAL GAZETTE. 146 



acres, with rocky bluffs at the northern and southern ends, a mile 

 and a half apart, named res|)ectively Roan High Knob and Roan 

 High Bluff, rising about 100 feet above the slope, the former reaching 

 an altitude of 3690 feet. The soil is deep, rich and black, the green 

 turf dotted with clum])s o{ Alnus viridis ?ix\6. Rhododendron Catawbiense. 

 'i'his latter presents one of the most beuitiful sights tliat can be imag- 

 ined, with its domes of rosy inflorescence 6 and 8 feet in height, and 

 so abundant that the whole mountain to]) is colored by it. The dis- 

 tinction between this and R. niaxiniiim, founded on the shape of the 

 leaves and the tomentoseness of young leaves and branches, is hard 

 to be maintained, in many cases. But the color is unlike any of the 

 numerous shades of R. maximum and the capsules are smooth, while 

 those of the other are viscid hairy. 



The hotel is built of logs, but is comfortable enough for a botan- 

 ist, and comfortably kept by Mr. L. B. Searle, who engineered the 

 road up the mountain. 



The average daily temperature is from 55 to 65 degrees ; twice 

 the mercury reached 75 degrees for an hour or two, and once it was 

 45 degrees. The spring \vhich supplies the house has a temperature 

 of 45 degrees. Roaring fires are in demand morning and evening. 



The first thing to be done, was to secure specimens of those 

 early species which were going out of flower. After that, the daily 

 task was to watch the successive blooming of different species, 

 and to explore new localities. 



In moist places we find abundantly Diphyllcia cymosa, Cardamine 

 Clcmatitis, Saxifraga civsa .ind Iciicanthemifolia, Ligiisticum actieifolium 

 and Chclov.e Lyoni. 



In the w(jods occur plentifully Thalidrum davatiim, Astilbe de 

 caiidra, Ariscema polymorphiini, the common species on the mountain, 

 with leaflets less acimiinate than A. triphy/liim, and the lateral ones 

 rhomb )idal. when not lobed, sometimes one, sometimes two- 

 leaved, /lex moniieola, Veiceinium crxtliroearpon, "a blueberry bush 

 with acranbeir)- flouer," Meiiziesia ferniginea, var ^^/oluilaris, a strag- 

 gling rusty .shrul), with the blossom of a checkerberry, and Galium 

 latifolium. 



Lower down are found jolentifuUy Blephilni hirsuta, Pyenanthe- 

 muiii moiitanum. Rudheckia laciniata, Cacalia renifoDiiis, Mouarda fistu- 

 losa and didvma, Lophanthus scropliularice/olius, Seutellaria 7'ersieolor, 

 Veratrum pan'i/lorum, and many other species more or less common 

 elsewhere. 



In the open plains we collect Trautvctteria palmala, Arenaria 

 Xlalm. Houstoiiia seifyllifoiia (e\trywhere forming e.xtensive patches, 

 so as tf) interfere with the grass) Houstonia purpurea, var. montana, 

 and Danthoiiia comprcssa. Among the njcks and on the edges of the 

 j)re(;i pices are found Paronychia ariiyroeoma, Geum radiatum -av^^ geni- 

 cula/iim, Heuchera i^il'osn, S'dum Rhodiola and telephioides, CEnofhera 

 glauea, Angelica Curlisii, Cynthia Dandelion^ var. montana, Vaceinium 

 Constabhi'i, I^eiophyllum buxifolium, var. prostratum, Campanula divari 

 cala, Cuseuta roslrala, Agroslis rupesfris, Carex u:sli7'alis, debilis, and
