In this concise and interesting eoharesiagate Professor Hein- 
richer summarizes, particularly from the standpoint of the 
cultivator, certain phenomena of structure and development in 
hemiparasitic and holoparasitic seed-plants, ile chiefly from 
the flora of Central Europe, and belonging to the Scrophulariacee, 
Orobanchacee, Convolvulacee (Cuscuta), Lauracee ote San- 
talacee, Loranthacee, and Rafflesiacee (Cytinus). The a count be
