but the result in the end is satisfactory, and I believe ‘that this interesting 
plant willcontinue to find a home at Kew, where also the only artificially 
raised O. Andersonianum that I know of is again in bloom. Its history has 
already been given (O.R., xviii. p. 212), and part of the plant was afterwards 
presented. R. A. ROLFE.

ITH the programme for the coming year, the Royal Horticultural 
Society has issued a leaflet respecting the revision of Pritzel’s Icones 
Botanicarum, a work which is already in hand, under the supervision of a 
Committee appointed by the Society. The original Icones Botanicarum, 
compiled by Dr. G. A. Pritzel, was published in 1866, and is an Index 
of published illustrations of every plant then known, and it contains over 
100,000 references to figures, the book and page being given in each case. 
Such a work was and is invaluable to those engaged in botanical or 
horticultural research, but as the last fifty years have been more productive 
of new plants than any previous half century, the necessity for revision and 
enlargement has been obvious for a long time past, and would have been 
carried out earlier had not war imposed a check. It is estimated that the 
new work will include about 250,000 references, and cost at least £3,500, 
possibly £4,000. Towards this cost the R.H.S. has voted £500 and the 
Veitch Memorial Trustees £100. The fund wasstarted with £250 from the 
International Horticultural Exhibition held in 1gr2. As the financial 
responsibility rests with the R.H.S., subscriptions are invited, and it is 
hoped that. everyone, whether a Fellow of the Society or not, who is 
interested in plants betanically or horticulturally, will make some con- 
tribution to a work which for the next 100 years at least will be the standard 
work of the kind. The names of those subscribing {1 1s. will be published

presentation copy; a subscriber of £50 will receive a copy bound in half- 
calf; and a subscriber of £100 will receive a copy bound in calf or vellum. 
The revision is being done at Kew, where the Director has found accom- 
modation for the typists who are preparing the manuscript. The members 
of the Pritzel Revision Committee are: Prof. I. Bayley Balfour, Mr. E. A. 
Bowles, Mr. F.J. Hanbury, Capt. Arthur W. Hill, Dr. B. Daydon Jackson, 
Mr. Gerald W. Loder, Sir Daniel Morris, Sir David Prain; (Dr A,B: 
Rendle, Dr. O. Stapf, and Sir Harry J. Veitch. | 
The revision of Pritzel’ was the subjeet of a lecture, by Dr. B. D. 
Jackson, at the R.H.S. meeting on January 28th, when the history and — 
objects of the work were explained.
