pass through their. life eycle ata great. rate, especially the 
herbaceous vegetation, and in order to obtain a good representa- 
tive collection it is necessary to carry on field work for a whole 
season. Up to the present Mr. Lely has collected nearly ‘six 
hundred specimens* and there is promise of more to follow. 
The fact that these represent about four hundred species of 
plants shows the care the collector has taken in order to avoid 
duplication of specimens. 
The following list of species indicates the large number of 
interesting new records for the flora of Northern Nigeria and their 
previously known distribution. It should be noted that the 
flora as represented by these examples is much more closely 
related with that of the East African plateau, the Zambesi Basin, 
and Angola than with the flora of Upper Guinea as a whole.
