362 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 



for his britannicum, which is based on the record in Lightfoot's Flora 

 Scotica, p. 455, but Lightfoot's record is taken from Sibbald, who 

 states that it was found " by the seaside between Blackness and the 

 Queensferry," and Lightfoot himself queries this record. If it were 

 ever found there it would be only as an alien, as which it has from 

 time to time appeared north of the Tweed. Petrak cites without any 

 query the plate in Sowerby [sic Syme] Eng. Bot. v., t. dclxxxvii. 

 The details of the hullschuppen in his monograph are drawn from a 

 Huntingdon specimen. He gives as its habitat " Locis apricis, lapi- 

 dosis, siccis, elatioribus Britannicae et Scotiae." But it is by no 

 means an upland species, in fact it is almost absent from our chilk 

 hills, and in Yorkshire does not ascend (see Lees Fl. N.W. Yorks.) 

 above 300 feet. Besides C. eriophorum 13 allied species are 

 described, as well as several hybrids. It is to be regretted that the 

 author had not the opportunity of seeing our British plant growing 

 in its native state. 



A Manual Flora of Egypt. R. Muschler. 2 vol., pp. 1312 

 8vo. Friedlander, Berlin, 40/. A most handy work written in 

 English, with an introduction by Prof. Ascherson and Schweinfurth, 

 with clear descriptions of 1504 species, an account of the Phyto- 

 geography and Geology, Glossary, Tabular view of Species, an 

 Alphabetical list of the Arabian names, and the history of Botanical 

 discovery in Egypt. We notice Weingaertneria is rightly retained in 

 preference to Corynephorus, despite the Actes, that Pennisetum 

 americanum L. correctly displaces P. typhoideum, but that Lepturus 

 incur vatus, Hordeum maritimum, and Juncus glaucus are wrongly 

 used for L. incurvus Druce, H. marinum Huds., and J. inflexus L. 



La Flore Saharienne, un Apercu Photographique. Dr A. 

 S. Gubb, Paris. Paul Geuthner, le Rue Jacob, 1913. pp. xxxii., 

 129, with 126 photo reproductions of characteristic desert plants. 

 The Arab names are given where possible, and many of the illustra- 

 tions are of plants in situ, not the least interesting being that of the 

 Cauliflower of the desert — the weird Anabasis aretioides from the 

 Sahara ou de Bou-Hamama, and that of the striking Phelipaea 

 violacea. The Rose de Sable does not, as its name might suggest, 

 belong to the Rosaceae, but is an extraordinary crystallization of 

 sulphate of calcium of a rose-like form varying in size from an 

 apple to a man's head.
