5 o ANNALS OF SCOTTISH NATURAL HISTORY 



without doubt as synonymous : the Arisaig locality is 

 not given ; nor is the fact that it represents C. camscens 

 in the Herb. Linn. C. Hudsonii, Benn., is used instead 

 of the earlier C. data, All., on account of the uncertainty 

 of Allioni's plant; but is there justification for this? 

 Under C. gracilis an additional variety to my List is given, 

 viz., var. sphczrocarpa (Uechtr.), from Sussex (Marshall), 2610. 

 The hybrid C. gracilis x Hudsonii (super- Hudsonit) is given 

 from Ranworth, Norfolk (C. E. Salmon). 



C. aquatilis, Wahl., a nova forma, angustata, Kuk., from 

 Forfar (Somerville), and Easterness (Marshall), is described. 

 Var. sphagnophila, Fr., from Clova (Boott.), S. Aberdeen 

 (Druce) 1218, etc., is also given. The var. epigeios (recorded 

 by Bennett) is made synonymous with stans (Drej.) Boott., 

 but is not cited for Scotland. Does it really occur there ? 



Hybrids of C. aquatilis x rigida and C. aquatilis x 

 Goodenoivii are from Scotland ; C. aquatilis x Hudsonii, 

 Ireland (R. W. Scully) ; C. aquatilis x salina, Wick 

 (Marshall). C. ccespitosa, L., is given, on A. Bennett's in- 

 formation, from Shetland (Beeby), and Yorkshire (Perceval) ; 

 but we still lack precise information of its occurrence as 

 British. C. Goodenoughii, as the spelling is altered to 

 here, has a var. recta (Fleisch), A. and G., which is a 

 common British form ; var. juncea (Fries) also frequent, 

 var. strictiforniis (L. H. Bailey), Altnaharra (Marshall) ; 

 var. subccespitosa, Kiik., Rosslare, Ireland (Marshall), and 

 stenocarpa, Kiik., based on my specimens from Glen Fiagh. 

 The last is also found in many other Scottish localities. 

 C. Goodenowii hybridises with rigida, Forfar, Argyll 

 (Marshall) ; and with gracilis ; but no British localities 

 are given, not even for x C. elytroides, Fr., which A. Bennett 

 recorded from Anglesey ; nor is the occurrence in Britain 

 of C. trinervis, Degl., also recorded by Mr. Bennett, alluded 

 to ; but doubts have been expressed as to the identity of 

 this, and therefore it is bracketed in my List till confirmed. 

 Neither is there any reference to C. hebridensis, A. Benn., 

 which is put under C. spiculosa in " Lond. Cat." as a var. 

 Kiikenthal considers C. spiculosa itself only a hybrid of 

 Goodenowii and salina super-salina, Kiik., but he does not 

 refer to a Scottish locality. Under C. rigida the var. infer-
