CENTRAL AFRICAN PLANTS 173 



botanists in Britain agree with Hooker in the colour of the 

 flowers, for, if so, the British plant may not be identical with 

 what is known as Papaver hybridum L. = P. hispidum Lamk. in 

 France. The root-leaves have a petiole as long as the leaf, while 

 the stem-leaves are sessile. On the under side of the leaves the 

 petiole has a prominent raised rib clothed with long bristly hairs, 

 which continue upwards along the centre of the leaf segments. 

 The peduncles supporting the buds are always much deflexed, 

 and afterwards assume an erect position. — H. S. Thompson. 



Paludella squarrosa in Cumberland ? — While engaged in 

 working through the collection of Mosses made by the late Rev. 

 Augustin Ley, which, together with his collection of Flowering 

 Plants, have been left to the University of Birmingham, I have 

 found a specimen of Paludella squarrosa, gathered by Mr. Ley, 

 labelled " Scawfell Pikes, Cumberland, August 1871." The speci- 

 men consists only of a single stem, probably found among other 

 mosses, and sent in 1874 to Mr. H. Bos well for verification. I 

 wish to draw attention to this specimen so that search may be 

 made for the moss in the above locality, with the hope that it 

 may be found to be still growing in Britain. — E. Cleminshaw. 



REVIEW. 



Wissenschaftliche Ergebnisse der Detctschen Zentral- Africa-Expe- 

 dition, 1907-1908, unter Filhrung Adolf Friedrichs, Herzogs 

 zu Mecklenburg. Botanik : herausgegeben von Dr. J. Mild- 

 braed. Parts i-v. Leipzig : Klinkhardt & Biermann, 

 1910-1912 (Price 21 m. 60 pf.). 

 This work is a record of the botanical results of an expedition 

 to Central Africa under the leadership of Adolph Friedrich, Duke 

 of Mecklenburg. The object of the expedition was a systematic 

 exploration of the North-west portion of German East Africa, and 

 of the great valley from Lake Kivu to the Albert Nyanza and the 

 neighbouring districts of the Congo Free State, whence a course 

 was taken across the continent to the Cameroon s. The numerous 

 memoirs by well-known experts contained in this record bear 

 eloquent testimony to the conscientious thoroughness with which 

 the task was executed. Our German brethren enjoy a deservedly 

 high reputation for energy and enthusiasm in the field, a reputa- 

 tion in no wise dimmed by Dr. Mildbraed, who accompanied the 

 expedition as botanist and under whose editorship the work has 

 been published. In the first part the Pteridophyta and Mono- 

 cotyledones are dealt with, the Ferns and the Orchids specially 

 predominating ; the second treats of the remaining Cryptogamia, 

 with the Mosses and Hepaticae as chief items ; parts 3 and 5 are 

 concerned with the choripetalous Dicotyledones ; while to the 

 Sympetalous part 4 is dedicated, its chief constituents being the 

 Rubiaceae and Compositae. 



The value to science of work of this kind is twofold. On the 

 one hand it introduces to notice forms, generic and specific,
