Catalogue of the African Plants collected by Dr. Friedrich Welwitsch 
in 1853-61. Dicotyledons, Part I. By William Philip Hiern, 
M.A., F.L.S. Pp. 336. 8vo. London. Printed by order 
of the Trustees of the British Museum, 1896. 
The volume under discussion is the first of a series and contains 
Ranunculaceae to Rhizophoraceae. Many new species are de- 
scribed and the very copious notes in reference thereto add ma- 
terially to the value of the work and bear testimony to the inde- 
fatigable ardor and ability of the collector, who had all the usual 
concomitants of African travel to struggle against, as well as to 
the patience and skill ofthe compiler. Dr. Welwitsch’s African col- 
lections have been estimated at upward of 5,000 botanical species 
and some 3,000 species of insects and other animals, a large 
proportion of which were new toscience. A second part will finish 
the Dicotyledones and a third one will be devoted to the remain- 
ing groups. In the nomenclature line there is much of interest, 
and among generic changes the following should be noted: 
Chienfugosia Cav. (1786) replaces Fugosia Juss.; Cracca L. (1753): 
Lephrosia Pers. (1807); Meibomia Heister (1732) ex Fabric. (1759), 
Desmodium DC. (1813); Canavali Adans. (1763), Canavalia DC. 
(1825); Doticholus Medik. (1787), Rhynchosia Lour. (1790)3

In this contribution we have the author’s final conclusions in 
regard to this exceedingly interesting organism—conclusions 
_which are amply defended by an array of facts which skeptics 
will find it difficult to controvert. 
What. appears like phylogeny is represented by the vertical 
arrangement of the organisms in well-defined zones, beginning 
with simple fibres and evolving upwards through “cakes” and 
“balls” of matted fibres into “ fingers” and finally into the gigan- 
tic coiled stems at the summit—a vertical range all told of some _ 
75 meters. A
