Introduction to the Catalogues 



In the plan of the catalogues of species collected by members of the 

 Allan Hancock Expeditions, families are listed according to the sequence 

 of the Engler and Prantl system. The genera and species are listed alpha- 

 betically under each family. The first entry under the species heading is 

 the citation of collection together with any note that the collector may 

 have left upon his field label. It will be noted also that I have included 

 the date of collection, which I estimate of some importance because it 

 gives a record of the time of flowering or fruiting. In cases where the 

 specimen is sterile, it is either so indicated in parentheses along with speci- 

 men citation or is noted in the following paragraph.
