Penstemon digitalis species, which can be important for taxonomy. Scientists estimated the genome size for 40% of the species in the genus; using "Flow Cytometry." "Penstemon digitalis" has one of the largest genomes of the genus"Penstemon". Like other "Penstemon" species, it is used in roadside planting because it is easily grown and showy. It is recommended for easy use in gardens from the Midwest to the Atlantic coast and Pacific Northwest by the American Penstemon Society. "Iowa's Living Roadway Profiler" from the Iowa Department of Transportation says that the plant's "decorative seed capsules add interest in the fall and winter". One of
New Drug Application Review should complete within 6 months. The decision comes in a "Complete Response Letter". Biologics, such as vaccines and many recombinant proteins used in medical treatments are generally approved by FDA via a Biologic License Application (BLA), rather than an NDA. The manufacture of biologics is considered to differ fundamentally from that of less complex chemicals, requiring a somewhat different approval process. Generic drugs that have already been approved via an NDA submitted by another maker are approved via an Abbreviated New Drug Application (ANDA), which does not require all of the clinical trials normally required for a new drug
