 he himself— p. 717— placed under A. albicans), noting as 

 differentials from his macracantha its somewhat thinner, 

 broader and less glaucous leaves with larger more hooked 

 prickles. Shortly after the publication of his monograph 

 he found a small plant, obviously of this alliance, in the Cor- 

 deroy collection, which, because of its few leaves, he called 

 paucifolia,— subsequently changing this to oligophylla when 

 the earlier name was found preoccupied. Mr. Baker follows 

 Jacobi's lead in ranging A. jmgioniformis among the flexible- 

 leaved species of his own group "Viviparae," — ^apparently 

 knowing it only from description. He also acts on sugges- 

 tions made by Engelmann in 1873, in treating A. Karwinskii 

 as a synonym of A. Ixtli* Here, for the first time, is given 

 a description, accompanied by a woodcut, of A. Corderoyi 

 (p. 398, /. 79), which, placed but one remove from A. IxLli 

 in the monograph, is said to be recognizable at a glance by 

 its very rigid narrow bright green leaves and by the shape of 

 its dark brown erecto-patent prickles. Mr. Baker's mono- 

 graph was rendered into Italian by Baron Ricasoli and the 

 translation published in the following year.f What was 

 said of these species in the Gardeners' Chronicle is here re- 

 peated (pp. 237, /. 24, 241, 306). Fenzi notes A. Besserer- 

 iaim as being cultivated in Florence J at this time; and a 

 few years later Croucher§ comments on it; and it (spelled 

 Besseriarm) and A. Corderoyi as then understood are saidj| 

 to have been collected by Roezl. Mr. Baker's conclusions 

 were embodied in Hemsley's list of Mexican plants,1I except 

 that A. Karwinskii is placed under A. rigida, which replaces 

 the Ixtli of Baker's monograph.
