﻿bank near Rhayader, Radnorshire, in 1888, by the Rev. A. Ley, and 

 distributed through the Exchange Club without a name. In the 

 summer of 1889 I gathered it from the same locality, when we came 

 to the conclusion that it was a hybrid between the above species. 

 It grew in one large patch consisting of scores of plants, and I have 

 seen nothing like it either from the immediate neighbourhood or 

 elsewhere. Both the supposed parents were growing with it, and 

 flowering at the same time. Dr. Lindeberg thought that it could 

 not be a hybrid for the simple reason that the two species do not 

 flower simultaneously. As a matter of fact, the railway-bank is 

 mown for hay, so that II. sciapkiium had been cut down just before 

 blossoming, and had thrown laterals freely, which bore flowers 

 much later in the season than usual. Both Mr. Ley and I are still 

 of opinion that the plant is a hybrid, though I admit the point 

 would be very difficult to prove. In character it is just intermediate. 



I have not attempted in these notes to deal with many points, 

 such as the sweeping changes in the section rigida. To give reasons 

 and data for all alterations and additions would far exceed the 

 scope of an already very long paper. Such deficiencies are, I trust, 



I cannot conclude without acknowledging the great assistance I 

 have received in this and other recent work from Miss R. F. Thompson. 

 I have also to thank the Rev. E. F. Linton for communicating certain 

 useful identifications he has recently received from Dr. Dahlstedt, and 

 other correspondents for various notes, information, and specimens. 



CONTRIBUTIONS TO THE FLORA OF SOUTH AFRICA. 



A number of Ericaceous plants which appeared to be new have 

 accumulated in my herbarium, and I had intended describing them 

 all. The appearance of the Index Kewensis has revealed the un- 

 expected fact that there are about 105 species there accepted which 

 do not appear in any form in Bentham's Monograph in DC. 

 Prodromus, vol. vii ; although by far the larger number of these 

 were published prior to 1840, the date of that paper. Species of 

 Linnzeus, Berg, Thunberg, Lamarck, and other old authors, besides 

 about thirty species of Tausch in the Flora for 1834 and 1839, 

 appear to have escaped Bentham's notice ; and there are also some 

 which have been subsequently published. Of many I have no access 

 here at the Cape either to descriptions or specimens. I have there- 

 fore confined myself (with one special exception) to species which 

 by the remoteness or the high altitude of their station may be 

 almost safely supposed to be undescribed. 



My friend Prof. Guthrie, who has studied this Order, has given 

 me so much kind help that the following pages are really as much 

 his as my own ; and it is only by his wish that it takes its present form.
