Pringle’s type specimens of A. Huachucensis Baker, and 
the Rothrock specimens upon which Dr. Engelmann founded 
his description of A. Parryi. I have, therefore, though 
with considerable hesitation and reluctance, provisionally 
brought the three forms together as one species. I have 
felt obliged to call it A. applanata (though I have not been 
able to examine the European type specimens), as that is 
the oldest name. The Mexican type is described as 
having leaves more narrowed above the base than we 
find to be the case in the proportions of ours in mature 
plants. Mr. Baker describes it as having leaves 8 to 12 
inches long, 3 to 3} inches broad at the middle, narrowed 
to 2 to 24 inches above the base; flowers greenish- 
yellow, 24 to 3 inches long. At the time of my visit 
to Texas the flowering season was practically over, and 
-I was only fortunate enough to secure a very few re- 
tarded flowers, which were yellow and smaller than Baker 
describes. The herbarium material from Texas is very 
scanty and consists of a set of leaves labeled A. Wislizeni, 
accompanied by a very few flowers and capsules, in the 
Engelmann Herbarium. These were collected by Dr. 
Havard in the Guadalupe Mountains, October, 1881, possi- 
bly with the purpose of showing variations in the forms of 
leaves. The flowers in this set are much larger than the 
ones I saw. They have their filaments inserted at or a 
little above the middle of the tube. If there is no mistake 
as to the localities in which they were found, it seems to 
indicate that there is another form which I have not been 
able to separate by leaf characters. I hope it may be 
looked for. Similar flowers were collected by C. Wright 
in New Mexico in 1851 and 1852 (his number 1906). 
These flowers are not accompanied by leaves. Compari- 
sons should be made with A. Wislizeni, which has a similar 
insertion of stamens. A. Wislizeni has been credited to 
Texas by Dr. Engelmann in his manuscript notes, by Dr. 
Coulter in the Botany of Western Texas, and by Dr. 
Havard.
