Saguaro boot -- A collaboration of hole-pecking woodpecker and hole-waterproofing saguaro cactus. I photographed some and decided to write more about them. (Jan 31, 2011 DYK w 5,100 hits)
Pseudobiceros hancockanus -- Who could resist Anna Frodesiak's request to write up this penis-fencing flatworm? Article was a 27B redirect when I set to work on it.
Gustav Gassner -- German botanist and phytopathologist who wrote the 1918 paper that called scientific attention to vernalization. He had an article in German Wikipedia; the 1931 text on food microsopy is still used and known as "Der Gassner." (Feb. 6, 2011 DYK w 706 hits)
Castilleja septentrionalis -- Lovely and endangered alpine flower also known as "pale painted cup." There seem to be a lot more Castillejas with no articles, so I will expand this article a bit and then probably create some more. (Feb. 18, 2011 DYK with 1.6 k hits)
Alan B. Slifka -- Philanthropic idealist whose goals included harmonious coexistence of Arabs and Israelis. Lots of obits but my favorite is the blogger who called him "a true lamadvavnik," one of the 36 righteous who keep humanity on track. (Feb. 19, 2011 DYK with 485 k hits)
