The history and geographica! distribution are amply but tersely 

 handled. The probable origin of the species of the region the author 

 finds is from North rather than South America, proofs of which 

 he finds in the plants themselves as well as in the known geological 

 history, which is also briefly treated. The paper is particularly 

 interesting as being the first coroprehensive treatment oftheagaves 

 of the region. The bibliography is füll and there are many economic 

 and other notes which, together with the copious illustrations, in- 

 dices and lists showing occurrence by islands, collectors and col- 

 lections, and common names, make a verj- usable volume.
