Report for 1912 of the Botanical Exchange Club. Vol. iii. 

 Part. iii. by the Secretary (June, 1913) : Part iv. by the 

 Editor and Distributor, John Cryer (August, 1913). 

 Price 3s. 6cZ. each. Oxford : Blackwell. 

 The earlier of these two parts is entirely the product of Mr. 

 Druce, and contains a great variety of material, some of which is 

 of considerable interest. Besides the " Plant Notes for 1912, etc.," 

 there is a section devoted to " Botanical Publications, 1912," con- 

 taining a list of the publications of the year and of such papers in 

 periodicals as Mr. Druce considered worth notice — Mr. Pugsley's 

 Monograph of Fumaria and other important papers published 

 in this Journal find no place. Obituary notices of Alfred Fryer 

 A. O.Hume, W. W. Fowler (adapted from this Journal), Thomas 

 Hilton, John Piquet, and George Maw — whose death last year we 

 omitted to notice — are followed by " new county and other 

 records" from various sources, mostly of Mr. Druce's own obser- 

 vation and including a large number of aliens. We note inci- 

 dentally that Mr. Druce queries the identity of Linum bienne 

 Mill, with L. angustifolium Huds. (see Journ. Bot. 1912, 246), 

 although he gives no reason for his doubt. "Vide spec." is 

 attached to many of the records, but we find no explanation of this. 

 The Eeport has for frontispiece a " new species " of Lepidium, 

 which is described by Dr. Thellung (who ought to know) as 

 L. peregrinum ; the figure represents a wretched specimen, with 

 hardly an indication of inflorescence, found by Miss Hayward, 

 with other species, on the too famous rubbish-heaps at Galashiels, 

 and supposed to be from Australia. If the figure adequately repre- 

 sents the material on which the species (which is described at 

 great length) is based — and if it does not, we do not know why 

 it is given — we think most botanists will hesitate before accepting 

 it. Aliens abound in the Pieport, but we do not propose to 

 mention them here. Three pages are devoted to Bosa Boths- 

 childii Druce — a plant which the describer has " associated with 

 the name of my friend on whose estate it grows " ; it also occurs 

 over a considerable tract of country. The plant knowm as Sedum 

 acre (Auct. Brit, non aliorum) is described by Mr. Druce's " dis- 

 tinguished friend Prof. Graebner" — who says it "belongs to quite 

 a large number of forms endemic in Britain" — as S. Drucei. 



Taraxacum balticum Dahlstedt has been found by Mr. Druce 

 in Oxfordshire : a hybrid between Linaria purpurea and L. 

 repens, which came up in Mr. Druce's garden, is described and 

 named x L. Dominii. The Plantago montana of Hudson, which 

 has been generally referred to P. maritima, is named by Mr. 

 Druce, who considers it "a distinct race," P. Hudsoniana. 

 There are some interesting notes on forms of Chenopodium album 

 by "my friend Dr. Murr, the well-known expert on this genus," 

 the exact status of which it is not quite easy to ascertain ; among 

 them several new names seem to have been secured. Two of Dr. 

 Carl Lindman's splits from Polygonum aviculare, with numerous
