In Erica the author still retains his own pet, "E. Mackaiana 

 (Bab.),''' as a genuine species ; and he still omits to notice at all the 

 equally remarkable Cornish variety, alluded to in the ' British Flora.' 

 This omission will not elevate the author's reputation as a man of sci- 

 ence ; and it is only in its bearings upon science that we here men- 

 tion the point. The Mackaiana [Bab.) has the leaves of ciliaris, with 

 the flowers of Tetralix ; while the Watsoni [Benth.) has the leaves 

 of Tetralix, with flowers like those of ciliaris. The existence of 

 these two crossing varieties, as they may be termed, lessens the pro- 

 bability that either of them is a true species. It is therefore remark- 

 able to find only the one, which our author stands sponsor for, con- 

 sidered to be deserving of notice in the Manual. But there is doubt- 

 less truth in the adage which predicts strangulation to a dog with a bad 

 name ; and the Cornish heath may possibly have received a name 

 not acceptable to the author of the Manual ; having been described 

 in De Candolle's Prodromus under the name above mentioned. Both 

 varieties, in their extreme forms, do look very like species ; but the 

 links of connexion with Tetralix are so close as to render their dis- 

 tinctness very questionable, to say the least. 



In Orobanche several changes occur. The species which English 

 botanists have hitherto designated " O. major [Linn.) " is re-named 

 " O. rapum [Thuill)^'' on faith of Fries, who deems the Linnean O. 

 major to be our O. elatior. O. barbata (" Poir^') of the former edi- 

 tion now appears with the substituted name of O. Hederae [Duby), in 

 consequence of Koch stating that the English species is not the true 

 barbata. The Rev. Mr. Here's Cornish plant is adopted as a spe- 

 cies, under the name by which it has been already recorded in the 

 ' Phytologist,' that of O. amethystea [Thiiill). Another species is 

 added under name of 0. arenaria [Bork.), about which we must ven- 

 ture to remain a little sceptical. Tlie alleged " O. lucorum [Branny^ 

 is not noticed as a British plant. 



Primula vulgaris and P. veris are still retained for distinct species ; 

 nor can we censure this continued separation of two quasi- species 

 which have several characters of dissimilarity so strongly marked.
