As has been already said, one of the chief means of tracing 
these groups is through the cultivated varieties. Perhaps also 
the greatest good to be gained from an understanding of the 
botanical types is in the light it throws on the history and rela- 
tionships of the horticultural forms. Let us examine them in 
order. 
PRUNUS DOMESTICA MALIFORMIS.—For his types of this group 
(var. Armenioides Ser.), Seringe referred to the cultivated vari- - 
eties Abricotée, Mirabelle, Drap d’Or, and Abricotée-hative of 
Duhamel.* The citation of the first, Abricotée, is evidently an 
oversight, and incorrect, the same variety being given under the 
next head. Of these the Mirabelle seems to stand most clearly 
for the group in hand. This Mirabelle is not the Myrobalan 
known in this country and referred here to var. Myrobalana. 
Just what it is does not seem to be perfectly clear, thoue" 
Koch5 has discussed the distinction at length and Downing 
describes and illustrates the variety separately. Nearly all the 
leading works on pomology give the Mirabelle similar treatment; 
and though I am at present unacquainted with any such variety, 
* Direct references are given to Traité des Arbres Fruitiers 2:93, 95 and oe 
to op. idem, ed. nov. 5: 195. Figures are cited carefully. This is true for ali vari- 
eties.
