Species of the Cladouiei by the act ion of Hydrate of Potash. 413 



f. adspersa, Flk. = Coem. CI. Belg. 175. In my herbarium 

 I have this state from Gand (Abbe Coenaans), Isus, Sima (Wil- 

 ford), Australasia (Colenso). 



f. recurva (HoflFm.) (Dill, xvi. f. 27 d) = Richardson, 26 ; 

 Mudd, B. C. 48, 49 ; Coem. CI. Belg. 185. 



This state I have from Louvain (Abbe Coemans), Bagni di 

 Lucca (Dr. Deakin), Pyrenees (Dr. Deakin and Mr. Spruce), 

 Yorkshire (Mr. Mudd), Leicestershire (Rev. A, Bloxam), and 

 Shropshire. 



Var. corymhosa, Nyl. = Coem. Clad. Belg. 184, 187, 188, 

 190, 191, 192, 193, 194, 195; Coem. 1030; Nyl. L. P. 22. 



This I have from Northern and Middle Islands and St. Pa- 

 trick's River (Colenso), Australasia (Dr. J. D. Hooker), British 

 Columbia (Dr. Lyall), Subat (Dr. Philippe). 



Dr. Nylander notes these reactions in herb. Delise : — C race- 

 mosa,\ar. niic?-ocarpa, Del. ,K—= [mihi corymbosa) ; C.racemosa, 

 var. thyrsoidea, Del., K— = {corymbosa) ; C. tortuosa, Del., 

 K— = [corymbosa] ; C. racemosa, var. rangifera, Del., is 

 partly corymbosa, K—', and that Pries, L. S. 58, " C. racemosa," has 

 K dilute fuscescens (= corymbosa); and also Fries, L. S. 117, 

 " C. subulata'^ K dilute fuscescens, and comprises (1) subulata 

 (= 6), {2)corymbosa (s= $), and (3) furcata, tenuis fuscescens 

 (K-). 



Var. spinosa, PIk. (Dill. t. xvi. f. 25) = Coem. Clad. Belg. 

 180, 186. 



This I have also from Kifferschwyl (Schsercr), Genoa (Prof. 

 DeNotaris). 



Dr. Nylander (m litt.) remarks that it will be necessary to 

 separate the C. spinosa (Flk.), given in Coem. Clad. Belg. 180, 

 under the name C. furcata, and with the synonym " C. ykr- 

 cata 7] racemosa subv. spinosa in hb. Flk.," and again in No. 186 

 under the name of " C. furcata," inasmuch as these two numbers 

 have the free reaction K + , which here indicates only a distinct 

 variety ; for there is frequently in furcata and corj/mbosa a slight 

 yellowish reaction which quickly turns to fuscescent. See also 

 remarks under C. verticillaris, antetl. 



Var. crispata, Flk. = Scha?r. 276, 277; Tuck. 31 ; Mudd, Br. 

 C. 45 ; Coem. CI. B. 199, 200; Richardson, 27, 28, 29 ; Fellm. 

 32,33; Anzi, C. C. 22. 



Dr. Nylander {in litt.) remarks that he considers crispata 

 to be nothing more than a variety of furcata ; just as amau- 

 rocrcea is of uncialis. 



I possess also specimens of crispata from Lheris (Dr. Philippe), 

 Peklin (Dr. Harslingsky), Bagni di Lucca (Dr. Deakin). 



32. C. grypea. Tuck, (in Agass. Journey to Lake Superior, 

 App.), is, according to Dr. Nylander {in litt.), distinct from^Mr-
