The population of Isoetes olympica near Suweida, Syria. I have been monitoring this population for several years. Our research during the past fifteen years has shown that this genus of grass-like plants, little changed since the days of coal swamps, has remarkable diversity in the Middle Atlantic States.
Dr Mustafa Pala and I examining an infestation of Cuscuta (probably C. palestina) in a lentil test plant at the International Center for Agricultural Research in the Dry Areas (ICARDA) research farm at Tel Hadya, Syria. I have worked on an ICARDA sponsored project for the past several years. May 2005.
Collecting Striga in Burkina Faso. This was so long ago the country was then known as Haute Volta and I had black hair! The majority of my research efforts over the past three decades has been with parasitic angiosperms, particularly those which cause damage in the African Sahel and the Middle East
Examining a shrubby species of Euphorbia near Fish River Canyon, Namibia. This shrub, which dominates the landscape, is the host of Hydnora africana one of the strangest plants in the world. It spends its entire life underground, dependent upon this shrub for its existence, then breaks through the rock soil and flowers. My colleague at the University of Namibia collaborates with my lab in this work.
En route to 4 000m to find the elusive nard, Nardostachys jatamsi. The well equipped, poised trekker in blue is Dr Luke Cutherell whose mountaineering experience proved invaluable. 5 July 2008 near Dunche, Nepal. 
My plant taxonomy class from the American University of Beirut at the Ehden Cedar Preserve on Mount Lebanon. Cedars are evident in the background as are patches of snow in this March photo.
I have a collaborative program with colleagues at the University of Peridenya in Sri Lanka. One of the areas of interest in that botanically diverse island is the Knuckles Preserve, shown here. It is an area of granite outcrops and seeps and home to at least one endemic amphibian. 
I am holding the pistillate inflorescences of Populus euphratica with the Euphrates River in the background. Eastern Syria at the city of Deir Ezzor. March 2007. This tree is likely the “Willow of Babylon” mentioned in the Bible.
The distinguished botanist/physician/Arabist George Edward Post (right), 1838-1909. One of the founders of the Syrian Protestant College, which became the American University of Beruit, Post published the first comprehensive flora of the Middle East. I have just completed a biography of his life and am editing his letters. Post also wrote extensively on plants of the Bible.
Entrance to Mor Gabriel Monastery near Midyat, Turkey. This is arguably the oldest monastery in continual use in the world. One of my interests is in the cultic use of plants by ancient Christian groups. May 2006.
Professor Gebisa Ejeta from Purdue University is on the right, holding Alectra vogelii, a serious parasite of cowpeas. I have the same in my hand. On the lower left is Striga hermonthica, the most serious parasitic weed in Africa which causes severa damage to sorghum (as here) but also other grains. This field trip was part of a Striga workshop held in Ethiopia. 10 November 2006. Professor Gebisa is the 2009 winner of the World Food Prize which has been called “the Nobel Prize for agriculture” for his work on developing Striga resistant sorghum strains.
On the west coast of the Greek island of Chios with an especially vigororous Onopordum sp. We were on the island to study Pistacia lentiscus var.chia which only grows here and is the source of mastic, a plant gum used since ancient times. 15 June 2009. 
Botanizing in Iraqi Kurdistan where I was accompanied by an armed guard on each trip.

The course is team taught with Professor Donald Leopold of ESF (not shown) and Peter Schafran shown in the middle of the last row.
