SHORT NOTES 47 



alba, Ulmus glabra, Salix caprea, S. caprea x {cinerea ?), 

 S. aurita x caprea, S. {aurita ?) x caprea, Taxus baccata and 

 Asparagus maritimus, whilst Marcliantia polymorpha covered most 

 of the bare places. There were no catkins on the willows, so the 

 Rev. E. F. Linton, who saw them in sitiX, could not with certainty 

 name all of them. The Mulberry {Morus nigra) occurred in this 

 same corner some years ago, but has been removed. On the 

 gravelled border of other parts of the court were to be found Ilex 

 Aquifolium, Gratagus Oxyacantha, Betula alba, Salix caprea, S. 

 cinerea x {aurita ?), and Asplenium Buta-muraria (growing from 

 a joint in the wall). Most interesting were two plants of the sea- 

 coast grass Festuca rottbcellioides, discovered by Mr. Jenkinson, 

 the Librarian, and transplanted by him from Clare College, where 

 numerous traces of it could still be seen in the autumn, though 

 the authorities had done their best to destroy it by means of a 

 weed-killer. Many of the above plants, unfortunately, were 

 ruthlessly destroyed during the holidays by the too energetic 

 gardener. The front court, too, has its interest for botanists. 

 Most Cambridge men have noticed the ferns Pteris aquilina, 

 Lastrea Filix-mas, Asplenium Trichomanes, and the beautiful tufts 

 of Asplenium Buta-muraria, that have for years grown, together 

 with Linaria Cymbalaria, undisturbed, with their roots deep down 

 in the cracks between the Senate House steps — " the best locality 

 for ferns in Cambridgeshire ! " All the ferns excepting A. Tricho- 

 manes occur elsewhere in the court. The list could be lengthened 

 considerably if the names were given of the flowers that make the 

 lawn gay in summer, when it has been left unmown for a short 

 time. In the middle court the most conspicuous plants during 

 the last year or two have been Erigeron canadense (in great 

 abundance), Epilobium montanum, and Linaria Cymbalaria. —

Euphorbia gibraltarica (pp. 10, 13). — The attribution of 

 this name to Mr. N. E. Brown is an error for which I am not 

 responsible. Mr. Brown was good enough to help me in working 

 out the species, but the ultimate naming and description are my 



own. A. H. WOLLEY-DOD. 



Utriculakia ochroleuca. — To the list of counties on p. 10 

 should be added: "92. Aberdeen S. Dr. Trail sp." — Arthur

That the first edition of this work, published in 1905, in two 



volumes, containing 581 and 1025 pages respectively, supplied a 



generally felt demand is sufficiently indicated by the fact that it 



has long been out of print. In view of the enormous amount of 



work published during the last eight years in this extremely pro-
