SHORT NOTES. 



trichoplnjJhim, as being ■without stipules ; he also wrongly describes 

 LeiiLdozia sctacca as being Avithout, although under the description 

 of the genus Lepidozia he says: "Plants stipulate." Mitten {Jonrn. 

 Linn. Sue. (1864) ), evidently dissatisfied with the company which IL 

 trirhophijlluw was in, removed it to a new genus — Cluctopds; but 

 as Spruce, Carrington, Stephani, and most authorities retain 

 DuuKutier's genus for this species, I follow them. — W. H. Pearson. 



PoTAMOGETON RUTiLus Wolfgang. — In the Berne Herbarium 

 (kindly sent me by Dr. Fischer) is a sheet of specimens labelled, 

 " Potcunogeton pmiUum. Ely, Cambridgeshire, 25 July, 1825 {Hensloiv, 

 1825)." Part of these are true pusillns, and part P. rutilus, but 

 they are not mixed, so that it may be a label has been lost ; they 

 are "Ex herb. Guthnick." Still this plant should be kept in mind 

 by British collectors. I am aware that Dr. Lees records it in his 

 Flora of West Yorkshire (p. 418), but his description will apply to 

 several forms of pusillns ; and in continental herbaria a proportion 

 of the plants under the name are not the plant of Wolfgang, although 

 several have three notes of admiration placed after the names. — 

 Arthur Bennett. 



Adiantum Capillus- Veneris at Morecambe Bay. — On July 13th, 

 1893, Mr. W. H. Stansfield, of Southport, and I, when botanizing 

 on the northern shores of Morecambe Bay, found Adiantum Capillus- 

 Veneris growing in cavities of the mountain limestone near the sea. 

 In July, 1894, we visited the spot again. There is a large tuft and 

 two small plants. We believe that the maidenhair is here truly 

 wild ; this opinion is shared by Mr. J. G. Baker, of Kew. The rock 

 on which it grows is that which it chooses for its home in Co. Clare; 

 the station is in the same latitude as its habitat in the Isle of Man, 

 and not sixty miles distant from it; the climate is little less favour- 

 able than that which it endures in the south-west of our island. 

 We gathered only one frond, which we have deposited in the British 

 Museum. — A. H. Pawson. 



Cnicus tuberosus and other Wilts Plants. — It may be in- 

 teresting to botanists to know that the rare Wiltshire thistle still 

 exists in the locality given for it in Preston's Flora of Wiltshire. 

 In 1891 I visited the place in June, but the specimens were then 

 very young, and were very difficult to recognise from C. acaulis 

 without the desperate resort of digging them up. In fact, I felt 

 some amount of doubt as to their being true C. tuberosus. Tliis last 

 September, while on a driving tour through western England, 

 I again visited the locality, and, as the plants were in good 

 condition, had no longer doubt as to their correct identity, nor 

 had I difficulty in separating them from the C. acaulis with which 

 they grew, and with which I believe they hybridise. Although 

 growing on a dry chalk down, some specimens of tuberusus were 

 two feet high. Occasionally the stem was branched, bearing two or 

 even three heads. The shape of the anthode is different from that 

 of acaulis, which is more cylindiical, while tuberosus is more hemi- 

 spherical. The colour of the flowers is also different in the two 

 plants ; C. tuberosus is more of a rose-pink colour, while acaulis ia
