QBARS - v30n3 J. F. Rock Rhododendrons 1929 Expedition

J. F. Rock Rhododendrons - 1929 Expedition
by Col. and Mrs. R. H. Goodrich, Vienna, VA

The following is a correlation of U.S. Dept. of Agriculture Plant Introduction Numbers, Rock Field Numbers, U.S. Dept. of Agriculture Plant Quarantine Numbers, and identification of the species. The Royal Horticultural Society Rhododendron Handbook, Part One, Species (1967) uses the USDA Plant Quarantine Numbers. An asterisk indicates the R. H. S had no listing of the species. In these cases, field notes are quoted. Personal notebooks of the late Joseph B. Gable of Stewartstown, Pa., were also used in this correlation. P. I.84174 (R.18442) identification is from Mr. Gable's notes. P. I. 84165 (R.18433) identification is from RHS 1972 Rhododendron Yearbook.

We are indebted to Dr. August E. Kehr of the U.S. Dept. of Agriculture and President of the American Rhododendron Society, for his aid and encouragement in this project, and to Mr. Howard Hyland of the U.S. Dept. of Agriculture Plant Introduction Division and his staff for assistance in locating data.
