Hoya stenophylla was named as a species by Rudolf Schlechter. I have seen his name attached to a number of Hoya species so I did a little research on him and will share some of it here. Schlechter was born in 1872 in Berlin, Germany and was the 3rd of 6 children. He authored several works on orchids and proposed at least 1,000 species in Orichidaceae alone. He traveled the world extensively collecting plants and spent several years in what was then called German New Guinea. It was while living here that he discovered H. stenophylla with the name meaning slender leaves. He died in 1925, leaving behind a vast herbarium, which sadly was destroyed in the bombing of Berlin in 1945.
