Databasing and imaging of the PH type collection was initiated as 'Virtual Types' with an NSF grant (#0545170) awarded to Lucinda McDade and James Macklin in 2006. Since 2008, continued databasing and imaging of the PH type collection has been supported by the Mellon Foundation as part of the Latin American Plants Initiative (LAPI)/Global Plants Initiative (GPI).
Specimens from the general and special collections are also databased on an ad hoc basis and can be found here.
