specimens from " White Moss, Blackley/' Some of the plants 

 occur now in other mosses in the neighbourhood, but in the cases of 

 Drosera a ng/ica and D. longifolia (1. 32) it is nect;ssary to travel con- 

 siderable distances to obtain specimens. The White Moss, at Blackley, 

 has now entirely disappeared ; indeed, in 1858 Leo Grindon writes of 

 it as having been drained and cultivated for many years. It is not 

 mentioned at all as a locality for the district by either Woods, in his 

 Flora Maiicimiensis, in 1840, or by Buxton, in the Botanical Guide, in 

 1846. The only other local record, though not one of the Manchester 

 District, which need be mentioned, is that of Sisymbrium Sophia 

 (VII. 18), from Tarvin, in Cheshire, which is a station considerably 

 further inland than any mentioned in Lord de Tabley's " Flora of 

 Cheshire," or in Green's "Flora of Liverpool. "" 



Apart from local records, however, the collection contains a 

 number of interesting plants. Among these is a very fine specimen 

 of the now exceedingly rare Ladies' SHpper, Cypripedium cakeolus 

 (V. 14), from Arncliffe, Yorkshire. This specimen is undated, but 

 as the volume contains most of the Manchester records, and as early in 

 the next volume are plants dated 1797, it was in all probability before 

 that date. If so, the record would antedate those given for this 

 region in Lee's "Flora of West Yorkshire," where 1805 is given. 



The collection contains examples of three plants which were at 

 that date claimed as 'members of the native flora. These are 

 Potentilla alba (I. 56), Helianthernutn ledi/olium (II. i5), under the 

 name of Cistus salicifolius, and Euphorbia ^^ Characias" (VII. 230.). 

 The specimens of the last named, though incomplete, are certainly 

 E. amyi:;daloides, and not E. characias, which is a S. European 

 species. The plants recorded for Staffordshire and Worcestershire at 

 the end of the eighteenth century were ahnost entirely large 

 examples (jf E. amxgdaloides. The other two, Potentilla alba and 

 Helianihemutn Icdifolium, are both contributed by Robson, of 

 Darlington, whom we know cultivated a "botanic garden." As the 

 collection contains other plants labelled as coming from Robson's 

 garden, no information can be gained about the plants. 



The following list of the vascular plants is arranged in systematic 

 order. In each case the generally accepted Latin name is given first, 

 this is followed by that used by Dalton, if different. Then follows 

 the linglish name used and the locality or source of the specimen 

 and any other information in the herbarium. Any additions or 

 remarks not in the collection itself are enclosed in square brackets [ ]. 

 The references to the volume and page are given for each plant ; 

 the number of the volume being first, in Roman numerals, and 

 followed by tlie page number.
