TAXONOMY : 
The currently accepted scientific name of heart-podded hoary cress is
Cardaria draba (L.) Desv. [8,12,17,23].  It is a member of the
Cruciferae family.  Heart-podded hoary cress was originally placed in
the genus Lepidium [34].  There are two recognized varieties of
heart-podded hoary cress [9,23,31]:

C. d. var. draba
C. d. var. repens (Schrenk) O. E. Schulz

According to Hickman [12], C. d. var. repens is a hybrid of C. draba and
C. chalepensis (lens-podded hoary cress) (L.) Hand.  

It was originally thought that there was only one species of Cardaria in
North America.  In 1933, Bellue reported three distinct species.  Some
taxonomists still do not distinguish between the three hoary cresses
[22].
