138 Johnson. — On Arceuthobium Oxycedri. 
examined by Solms-Laubach. A summary of the investi- 
gation as a whole is given at the end of the paper. My 
knowledge of the plant is limited to spirit and herbarium 
material, all the figures being derived from spirit specimens 
of the plant, for which my thanks are due to Dr. Scott, to 
whom the material was given by Mr. Thiselton Dyer.
