the "Viviparae." A. Karvyinskii is kept as a synonym of 

 A. rigida, under which A. Ixtli is also entered, and which 

 A. Corderoyi immediately follows with the statement, once 

 more, that it was introduced through De Smet by Roezl. 



In his now otherwise voidable group ''Integrifoliae," Mr. 

 Baker here describes (p. 185) as A. integrifolia a plant with 

 rigid glaucous leaves devoid of prickles, received in 1S85 

 from the Missouri Botanical Garden. \Miat is said of it 

 hardly permits it to be placed far from macroacantha except 

 for the absence of marginal prickles. Mr. Gumey, long the 

 Head Gardener of the Missouri Botanical Garden, remembers 

 that somewhere about 1880 a packet of seed of "A. Bes- 

 seriana" was received (as he thinks from Haage and Schmidt), 

 from which not far from 100 seedlings were raised. All are 

 said to have been glaucous, some less than others; and he 

 recollects that while most were very prickly some were armed 

 only at the apex of the leaves. The local absence of prickles 

 on A. macroacantlia had also been noted by Salm.* There 

 seems to be a bare possibility that the type of A. integrifolia 

 was an extreme form of this lot of seedlings, of which several — 

 all, however, of the prickly macroacantha form — are still 

 extant. 



In 1893 a plant which had been obtained in 1875 from 

 Nardy of Hyeres, under the name A. Corderoyi, flowered at 

 Palermo. Not being satisfied with the name that it bore, — 

 as had been true in nearly all of the observations made by 

 Todaro on plants brought to maturity in the same garden, 

 when comparison was made with the type descriptions of 

 small specimens, — Dr. Ross, who was then at Palermo, 

 submitted a leaf to :Mr. Baker, who confirmed hi.s doubts, 

 so that the plant was describedf and subsequently well 

 figuredj by him under the name A. Bakeri. A leaf of a sim- 

 ilar plant cultivated at the Missouri Botanical Garden as A. 

 Corderoyi and understood to have been obtained as A. lurida 

 Jacquinixina from Ellwanger and Barry between 1875 and
