History of botany scope of the subject as technology has opened up new techniques and areas of study. Modern molecular systematics, for example, entails the principles and techniques of taxonomy, molecular biology, computer science and more. Within botany there are a number of sub-disciplines that focus on particular plant groups, each with their own range of related studies (anatomy, morphology etc.). Included here are: phycology (algae), pteridology (ferns), bryology (mosses and liverworts) and palaeobotany (fossil plants) and their histories are treated elsewhere (see side bar). To this list can be added mycology, the study of fungi, which were once treated as plants, but
On the cultivation of the plants belonging to the natural order of Proteeae conserved. However it was not possible to conserve species names until the 1980s, by which time the priority of Salisbury's species names had long been accepted. Thus "On the cultivation of the plants belonging to the natural order of Proteeae" is the source of numerous names of Proteaceae taxa. On the cultivation of the plants belonging to the natural order of Proteeae On the cultivation of the plants belonging to the natural order of Proteeae is an 1809 paper on the family Proteaceae of flowering plants. Although nominally written by Joseph Knight as a paper on cultivation techniques, all but
